Title: [ANN][GRS][DMD][DGB] Pallas optimized groestl opencl kernels Post by: pallas on September 12, 2014, 08:00:34 AM **** MYRIAD GROESTL ****
If you are looking for the closed source myriad groestl miner (for DGB, SFR, etc.) look here instead: https://satoshibox.com/fttcfvpiyhbod7ueidmgdhym ABOUT This is my optimized Groestlcoin / Diamond and similar opencl kernel (groestl + groestl algorythm, not myriad-groestl which is groestl + sha, see the top of this post for the latter). It is based on the sph version originally available on sph-sgminer but is now totally rewritten. It should be compatible with all sph-sgminer versions and derivates. PERFORMANCE v1 - to be compiled with catalyst 14.6 or 14.7: R9 290x @1125 Mhz: ~26.4 Mh/s R9 290 @1200: ~25 Mh/s R9 280x (stock): ~18 Mh/s 7950 @1200: ~16 Mh/s R9 270X: ~9.7 Mh/s v2 - experimental hawaii only bin: R9 290x @1125 Mhz: ~34.4 Mh/s R9 290 @1100: ~30.6 Mh/s Wolf0's Tahiti binary: R9 280x: ~25 Mh/s HOW TO USE - Stop the miner - Replace groestlcoin.cl, diamond.cl and/or the kernel you want to use with this one (it's inside the "kernel" folder) - Remove all the .bin files (in the main folder) - Set worksize to 256 only (-w 256) - Run and enjoy! TWEAKING Set intensity from 20 to 22. Thread concurrency and all the other parameters are useless. This kernel doesn't make use of gpu ram, so set the ram clock to THE MINIMUM POSSIBLE VALUE; for example 150 MHz for R9 290. Now play with the core clock until you find the highest stable value (probably between 1100 and 1200 for the R9 290). COMPATIBILITY Tested working stable on R9 290, 280x and 7950. Should work on any recent amd gpu but performance is not guaranted to be optimal. I doesn't work with cryptohunger optimized pool: use the conventional port or another pool. Also do not replace the optimized kernel of grs-sgminer but the normal one. TROUBLESHOOTING Try the following: - Sure you set worksize to 256? - Replace the generated .bin file with this one (64 bit, r9 280(x) and 290(x) only): LINK EXPIRED (diamondHawaiiw256l8.bin), see below for a newer binary file - Lower the intensity - Lower the core speed (are you sure you put the ram clock to the lowest possible value?) - Since it uses more power, it could be a cooling issue too: check the gpu temperature DONATIONS This work took me months of coding and testing and unslept nights; please show your appreciation (you are making more money by using it!) by donating to: BTC: DISABLED DOWNLOAD Opensource Kernel (v1): https://app.box.com/s/9vikvemf7acio3uns7taorodqmod42ej Experimental Hawaii bin (v2): https://app.box.com/s/zsr29tfgv4tpxs1q7451dayzaw3wnoee Wolf0's Tahiti bin (https://bitcointalk.org/index.php?topic=779598.msg11778971#msg11778971): https://ottrbutt.com/miner/wolf-groestlcoinTahitigw256l4.bin Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: pallas on September 12, 2014, 08:19:21 AM A BIT OF HISTORY
The first gpu miner for groestlcoin and similar was sph-sgminer by phm. Optimizing the original implementation was trivial (almost 3x the speed could be achived!), so probably there are tens of optimized versions around, many of which have been kept private: mining groestlcoin and similar was always unfair for most people, at least for non-devs. Hopefully this kernel will end this and should also level the field between amd and nvidia. I believe my version is faster than many of the other kernels because of the time I dedicated to it and the thousands of tests I did. FINAL ADVICES I suggest to keep "good binaries": make a backup of the fastest .bin files you have, so you can recover them in case of driver problems. Also this will enable you to get 1 o 2 percent more hashrate because of compiler variance (try removing the bin and running 3/4 times to see the variance in action). Or use the provided bin file (see the OP) which should be a good one. I've experienced lower power usage with catalyst 14.9 compared to 14.6 beta (a bit less compared to 13 but still better). Speaking of optimization, this should be kept in mind: buy a power meter for your miner(s)! But it looks like the compiler included in 14.9 drivers produces binaries which run considerably slower than older releases. If you are on 14.9, use the provided bin file instead of the kernel source in .cl format.

Good stuff! Have you tried other groestl algorithms? Like byte slicing or bit slicing? Did you also have strange situations where better looking code actually ran slower? PS: I wish you had opened the code earlier, Groestlcoin even had a bounty for an optimized miner. Thanks srcxxx Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: pallas on September 12, 2014, 09:00:40 AM Hi pallas! Good stuff! Have you tried other groestl algorithms? Like byte slicing or bit slicing? Did you also have strange situations where better looking code actually ran slower? PS: I wish you had opened the code earlier, Groestlcoin even had a bounty for an optimized miner. Thanks srcxxx I did a lot of optimizations which looked smart but lead to slower code. You can't imagine how many. Some of them I though of while in bed and made me not sleep until I could try them. Then the delusion :-D I believe it's because of the optimizations the compiler does but most of all about local memory and cache access. If you optimize some instructions but leading to less parallelism in memory access, you'll get slower code. That's typical for groestl because the speed is limited mostly by the memory (otherwise it would be faster like keccak, blake etc.). I know there was a bounty: my code was unfinished and, at the time, it was the only way I could mine without loosing money.

I know there was a bounty: my code was unfinished and, at the time, it was the only way I could mine without loosing money. I know. I actually think that the compiler is not that clever and that's why sometimes worse code runs faster. Also, I looked at ASM and some stuff there is just plain not optimal. Perhaps it'll be improved in future versions of AMD drivers. Also, most ASM code only uses .xy from a register. I tried making it work on ulong2 or ulong8 - only slower. I wish it was possible to write GPU code in assembler... Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: pallas on September 12, 2014, 09:33:44 AM Again it's mostly about memory for groestl: optimizing register operations might lead to unnoticeable gain but you may loose on memory access.

To use the bin file correctly, you have to remove all bin files in the main folder, download pallas bin file, put it into the main folder, start your miner, copy the filename of your automatically created bin file after you started the miner. Then you stop the miner and rename pallas bin-file with the copied filename.

I am not sure if you understand it yet, but your profits are not going to increase. Unfortunately. :-( Perhaps in the upcoming 5-10 days, but then it'll all be as before. And you'll be paying more for electricity. That is one of the reasons I did not open source my miner. Cause not only you are going to move to the faster kernel. Everybody will move to the new kernel. So not just your hashrate will increase, everybody's hashrate will increase as well. And so, the total coins distribution between miners will not change, but you're going to pay more to electricity companies. The new kernel eats a lot more electricity and makes more heat. Which is bad for the algo we're mining. Also it makes CPU mining a lot less profitable compared with GPU mining. Also bad. The root of all evil, srcxxx Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: pallas on September 12, 2014, 10:20:01 PM Hi guys!

The root of all evil, srcxxx hmmm not exactly. the biggest miners are already using optimized miners made by themselves; this kernel puts the common people on a higher level so they can compete. smaller miners will make more coins and biggest ones less.

Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: pallas on September 16, 2014, 09:35:23 AM if someone is still getting hardware errors, ensure you are using a worksize of 256 (-w 256 on the commandline).
some optimizations depend on it so don't set it to a lower value. also don't set it to a higher value simply because 256 is the maximum and that value will be used instead.

I didn't quite grok all your tricks :) I only use 3 arrays of 32 integers for intermediate results, so memory usage should be almost minimal and such buffer reusing could be an independent optimization, quite sure you have tried the rest :) Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: pallas on September 24, 2014, 05:58:15 PM I did the best I could to reduce register usage, but in the end using more 64 bits turned out to be faster. Probably private memory is not fully used...

(was stable at 1.087v using previous kernel). Best for me 1160gpu/1500mem threads 1, TC 24576 (it does make a difference). Temps rise dramatically with minor increase in voltage sadly and have capped my overclock attempts as over 75c is enough for me :( I have been unable to lower mem clock it seems to be locked (powercolor R9 280x). Cooler ambient temps coming but will not gain all that much as temps seem to rise exponentially with overclocking (nice heater LOL).

You should be able to push 73+ Mhs with 4 cards ... (volt mod and proper heatsink paste application). It's a pity you can't reduce mem clock because it would save you watts and lower the card temperature (and also let you overclock the core more). I think the 280x has a maximum core/ram clock range like the 7950: I used to set it at 1150 core and 1000 ram. If the hashrate changes with thread concurrency, it's probably just compiler variance and not due to the TC buffer which is not used at all. Try removing the bins and restart a handful of times, you'll probably see different hashrates with the exact same settings. Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: utahjohn on October 01, 2014, 04:21:10 PM Researching inability to lower mem clock, I use VBE7.0.0.7b.exe and atiwinflash to do the volt mod on 280x and 7950.

Temp dropped from 76-77C to 72C with current settings (1170 GPU 500 MEM) 18.5MHs after 10 min ... will probably lower memclk to 150 like on OP :) Lowered memclk to 150 by bios mod and gpu to 1.112V Temp 71C after 25 min at 1171/150 18.48Mhs :) I'm happy with that and will leave it alone for a week to see if stable :) Display driver crash after 30 min, lowering clock by 1 ...

Could you share your full set of parameters passed to the sgminer? Me, on 280x I can't get past 7.45 Mhs, with the sph-sgminer version 4.1.0-105-gf02f. The hash rate increase due this optimized kernel has been about 7% only. Thanks. Could not locate 14.7RC3 (I am on Linux), only 14.4, will try. The bin provided by pallas is for Hawaii (290), not for Tahiti (280), correct? this is 14.9 (non-beta) for linux: http://support.amd.com/en-us/download/desktop?os=Linux+x86 the hawaii binary should work on tahiti as well. Any benefit for upgrading to 14.9? using the old binary, made with 14.6, I noticed less power usage with 14.9. Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: DMDCreeper on October 03, 2014, 03:48:43 PM I am getting better hash rates with this than with grs-sgminer (solo mining).
R290 - 20.8 mh/s vs 18.3 mh/s with grs R280x - 17.3 mh/s vs 14.6 mh/s with grs I am not seeing much advantage to increase intensity above 20. I am seeing that both cards are running hotter - using more power. I have the 14.6 beta driver package installed. However, I have two questions about what I am seeing. 1. My R290s are set to 1100 for GPU speed, yet they are actually running under 1000. I am seeing speeds of only 937. auto gpu is disabled. I increased powertune to 20 and the gpu speed increased slightly but not to the speed setting of 1100. Can anyone explain this? 2. I set the memory speeds on the R290s to 150. With grs-sgminer I don't have to, they run at that speed simply because the memory is not used. With this software, the memory on the R290s runs are 1250 and I cannot change that. On the R280X, the memory is running at 1500 and I cannot lower it no matter what I set it to. Can anyone explain this? BTW, I was using the 13.12 driver package before and I could not get the hash rates that I am getting with the newer drivers. The best I could get out of the R290s was about 13.8 mh/s. With grs-sgminer and the 13.12 drivers I was getting 18.3 mh/s.

If you can't get linux tools to mod the vbios, PM me for options. Also note that vbios is card mfr specific, so I can't just give a .ROM for Powercolor card and have it work on a different card ...

Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: pallas on October 07, 2014, 08:02:36 AM It looks like the compiler included in 14.9 drivers produces binaries which run considerably slower than older releases.
The same happens for other algorythms as well, for example on X11. I've tweaked the code a bit but I still can't reach full speed, so I will keep on trying or, eventually, wait for a new driver release. Meanwhile, if you are on 14.9, use the provided bin file instead of the kernel source in .cl format.

Optimizing the original implementation was trivial (almost 3x the speed could be achived!), so probably there are tens of optimized versions around, many of which have been kept private: mining groestlcoin and similar was always unfair for most people, at least for non-devs. Hopefully this kernel will end this and should also level the field between amd and nvidia. I believe my version is faster than many of the other kernels because of the time I dedicated to it and the thousands of tests I did. FINAL ADVICES I suggest to keep "good binaries": make a backup of the fastest .bin files you have, so you can recover them in case of driver problems. Also this will enable you to get 1 o 2 percent more hashrate because of compiler variance (try removing the bin and running 3/4 times to see the variance in action). Or use the provided bin file (see the OP) which should be a good one. I've experienced lower power usage with catalyst 14.9 compared to 14.6 beta (a bit less compared to 13 but still better). Speaking of optimization, this should be kept in mind: buy a power meter for your miner(s)! But it looks like the compiler included in 14.9 drivers produces binaries which run considerably slower than older releases. If you are on 14.9, use the provided bin file instead of the kernel source in .cl format. If you want to fix it for 14.9, remove the naive implementation of the B64_# macros and use swizzle. Worked for me. Thanks, but I've already tried any combination of bitwise operations and vectors (as_uchar...): I could make it work but hashrate is about 20 Mh/s vs 25 Mh/s of 14.6 beta.

Ah, I see - I just saw it go from 7MH/s to... I think 20, on 14.9, so I figured it worked; never mind, then.It's funny how some little changes lead to huge hashrate drops (depending on compiler version); but it's true for memory intensive algos only, as far as I can see.

Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: realhet on December 31, 2014, 10:59:08 PM Hi All,
I registered here because I need a little help from you, who develops this OpenCL kernel. A month ago I've found the Groestl algo on the amd dev forums, thanks to Wolf0 who mentioned it on there. I thought it will be a good algo to test my skills in GCN asm, and I'd like to play with it, maybe I can optimize it better than the OCL compiler (or maybe not, but at least I can learn from it anyways). So the help I'm seeking is this: - Please send me the latest version of this kernel (I see everyone altering it a bit, just don't know which is which) - And pls give me a test vector with these things: - global kernel dimensions, workgroup size(I guess it's 256) - kernel parameters: dump "char *block", and the "target" value - And of course the above testcase must find a GroestlCoin hash. Thank you in advance (I already sent it to Wolf0 on the amd dev forums, but the moderation there can take more time there and later I found this more appropriate place for my question) And have a Happy New Year, btw Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: realhet on January 01, 2015, 09:22:12 AM how exactly do you do GCN ASM? I'm interested. I wrote an assembler for it. You can try it at realhet.wordpress.com. (Use Cat 13.4 or older, otherwise examples will crash.) My first thoughts compiling the OCL kernel (on a 7770): - Its 2.5 times bigger than the instruction cache. (and there are no loops in it, so I guess it often reads from ram.) - T0 and T1 is located in the gpu ram. - VReg count is above 128. -> that allows only the minimum no of 4 wavefronts/CU. So there are no latency hiding via parallel wavefronts. - too short kernel with too much initialization: Ideally I'd let every workgroup run for a minimum of 0.5 sec. So kernel launch and LDS table initialization would take no time compared to the actual work. - better instructions: BitFieldExtract for 64bit rotate, ds_read2_b64 for 128 bit LDS read. - balancing load between LDS and L1 cache I don't know which of the above is an actual bottleneck or will be usefull, but I wanna find out.

Also I only tested it with Tahiti and Hawaii cards. Kernel size: it can easily be made smaller (for example by including a single table instead of 2), but in all my tests it doesn't bring any advantage. T0 and T1 are not in gpu ram: it would be much slower if they were. They are in constant ram, I believe. Short kernel: even though you might design it in order to process multiple hashes in a single run, I think it's not worth. Simple proof: algos which are tens of times faster than groestl, like keccak, still do a single hash per kernel run. Another reason is that making the kernel last longer will result in more rejected shares. Balancing load between local ram and cache (or whatever balancing of memory reads): I believe that many optimizations that do not make sense, work because they intrudoduce little delays that permit better memory reads between the threads. They sort of better fit together. In fact, modifying the code on other parts of the code may make the same optimization worthless. Interesting speed variations may be brought by switching instructions or grouping local ram reads differently, for example. Hope that helps.

My instinct is to push it till it moves, crank it to 11, but that doesn't work with the R9-290. Doesn't work because it's throttling for power considerations long before you're hitting 1150. Just dropped my voltages right down and finally got 23.5 at 1125, I-20. New understanding of how to handle this card will make for better benchmarks, for true.

Thanks for the ideas! Actually I knew it from the disasm, that it uses ram instead of LDS for T0, T1. (Note that there is no such thing as constant memory in GCN. It can read a single value with the Scalar ALU and broadcast it across all the wavefront's workitems or it can read 64 values for a whole wavefront by the Vector ALU. Because T0 is addressed by data, it must be read by the VALU using L1 cache (there is a scalar cache too)). And from there I had the idea of balancing the two sources (LDS and L1). I did a simple test: renamed T0 and T1, and allocated a new T0 and a T1 from __local. And then initialized them properly. Result: all tbuffer memory read instructions disappeared from the disasm, and the hash rate is dropped from 3.99 MH/s down to 3.841. Don't know how much is the penalty of copying T0, and T1 into the LDS, though. By the 'textbook': L1 cache can read 4bytes/cycle, LDS: 8bytes/cycle And yes, the OpenCL compiler is totally unpredictable. Important question: In the MH/s calculation 1 kernel thread execution means 2 Hashes, right? (I have a HD7770 @1000MHz, and it's at 4MH/s which looks similar to Wolf0's report on dev.amd.com: R9 290 @1200 20MH/s. Using 14.9 where the compiler generates slower code.) Now I have to convert all the math into asm. That's painful :D Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: utahjohn on January 03, 2015, 03:22:57 AM @realhet
please share your work with the rest of us if it works out that assembly optimization works out. Looked at r9-285 review today, looks promising as long as smaller memory bus (256 vs 384) doesn't bottleneck. Should be faster than 280x and on par or maybe even better than 290 with lower power requirement ... May need tweaks for each architecture ... can it be written to detect which card it's running on and auto select best? A quote from AnandTech review : Quote A complete Tonga configuration will contain 2048 SPs, just like its Tahiti predecessor, with 1792 of those SPs active on R9 285. This is paired with the cards 32 ROPs attached to a 256-bit memory bus, and a 4-wide (4 geometry processor) frontend. Compared to Tahiti the most visible change is the memory bus size, which has gone from 384-bit to 256-bit. In our look at GCN 1.2 well see why AMD is able to get away with this the short answer is compression but its notable since at an architectural level Tahiti had to use a memory crossbar between the ROPs and memory bus due to their mismatched size (each block of 4 ROPs wants to be paired with a 32bit memory channel). The crossbar on Tahiti exposes the cards to more memory bandwidth, but it also introduces some inefficiencies of its own that make the subject a tradeoff. Meanwhile Tongas geometry frontend has received an upgrade similar to Hawaiis, expanding the number of geometry units (and number of polygons per clock) from 2 to 4. And there are actually some additional architectural efficiency improvements in here that should further push performance per clock beyond what Hawaii can do in the real world.

But they run a bit different code: the first is optimised because part of the input is known in advance and the second because the whole hash is not needed.

Finally I'm at the point that it first time ever produced a correct result.

The first improvement, 1.17x, is about the same as the 20% that is lost on 14.9 compared to 14.6 beta, so the two implementations are equivalent. The second, 2.34x, is really impressive: I have tried multiple times to reduce the number of variables as much as possible (down to 3x16 ulong arrays, 2 ulong and 2 uint), but the results were always worse, so probably that improvement can't be implemented in opencl, or at least I don't know how to. The same for code size and instruction cache: I was able to squeeze it to about 50K, but at a speed loss. About the compiler than can eliminate the constant calculations: I noticed that, but doing it by hand works best both in terms of speed and kernel size. Finally, a question about your work: do you plan to opensource it? Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: realhet on January 04, 2015, 11:26:22 PM Hi,
The Groestl asm code is opensource (I just uploaded it). My compiler and IDE is closed source though, but once you compiled the kernel with it into an .ELF binary, you can use it even on Linux, not just Win. The first asm version is documented on my blog. Check it out here -> http://realhet.wordpress.com/ (http://realhet.wordpress.com/) It's only a development version, and the kernel parameters are incompatible with Pallas's OpenCL kernel. I have a hard time reverse engineering how params are passed through registers, not mentioning that it can be different in every catalyst version so I keep parameters simple. One buffer with pinned memory for everything data IO is the fastest anyways. I'm planning to post about many optimizations. Let's see how far can I go. With using only 128 VGPRS it is already at 2.3x speedup and I'm expecting more. ;D I believe that OCL is so generalized and is kinda far from the actual GCN hardware that it is worth for some projects to go low level. (Not all projects: For example I have failed with LiteCoin. It's better for it to stay in maintainable OCL code.)

I'm at 2.65x now. Thanks very much! Unfortunately it appears the two optimisations are hard to implement in opencl: minimum code size I was able to achieve was 50K, far from 32k, and reducing the number of variables as much as possible didn't provide any speed up. Maybe the number of vregs is still higher than 128...

I've been using Linux only for many years now, so I can't help you on windows compiling; just know it's trivial to compile the miner on linux, it runs on a terminal so doesn't need qt. About the software version, I prefer the good old sph-sgminer which is based on sgminer 4.1, (I modified it a bit) but you can use the latest sgminer 5.X as well. To test the kernel you can simply point it to a pool, printf the hash or whatever. Back to my opencl effort, I've reduced the number of vgprs to 147 but I'm struggling to get past that.

Then it got all the goodies: vgprs, icache and 2ram+6lds reads. The speedup must be the same 3.5x! Is it that much? It must be good on small cards either, only important difference is the number of CUs anyways.

If it's as fast as the asm version, then I don't have to deal with the kernel parameters, which is boring/painful.

I really thought you had it 3.5x faster.
Are you sure that it only uses 123VGPRS AND code size is 28KB only? Or does it started to use Scratch regs (those are terribly slow)? Unfortunatelly I can't try on anything else than HD7770.

I'm not familiar with the latest GCN chips (I think AMD only improve their instruction from time to time, and maybe cut down double precision performance), but with this particular program, I'm pretty sure that it will bring the 3.48x speedup on the R9 290x too. Because all the CUs can work alone using LDS and L1 cache and ICache on their own, that's why. So if current ocl code on the R9 290x runs at 20MH/s then the latest asm code should be run at 70MH/s.

Does sgminer has an offline 'diagnostic' mode, just for testing the kernel if it runs and how fast it runs? "I'd need the linux version of the assembler." Sorry, it's impossible. It's not even written in Cpp just to be able to compile on any other system, than win. And to make things more complicated :D You have to compile with it for every type of gcn cards multiplied by every Catalyst driver that was altered by AMD developers.

So count me in on new kernel, I donated a bit last time u did new kernel and will donate again for new super-super asm kernel :)Let alone contributing to the code (2) or donating (2), in the whole life of this thread. I expect diff will drop remarkably when Rwd drops and solo mining might still be attractive even aftre ... I have 1 280x solo mining DMD (Pallas Diamond) approx 18.6 MHs (2-4 coins per day) and 7950 solo mining FTC (neoscrypt) 278 KHs (would be sweet if these opt'z could be applied to Neoscrypt also ... wolf0 where are u?) @realhet Would be great if you could add a kernel setting parameter (perhaps realhet) that selects using your kernel and supply a windows x64 build of your sgminer ... I'd donate for that :) Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: realhet on January 10, 2015, 01:41:26 AM Well, I found it better not to alter sgminer, that I'm totally unfamiliar with it and rather started to turn my kernel to be exactly the same as groestlcoin.cl from the outside. It will be a half page of additional code that deals with the kernel parameters. With a small dummy kernel it is already working now, but I'm just too tired to continue now. :D

http://x.pgy.hu/~worm/het/my_first_grs.png I'm the proud owner of my first 19 GRS coins, haha. I guess I was super lucky to get an 'accepted' right after 10 minutes of mining. The speed increase in sgminer is the same that I measured in my 'workbench': From 2MH/s it raised to 7MH/s. (Or if we calculate in GroestlHash/s then it is 4MH/s -> 14MH/s.) If anyone willing to help me testing this, please tell me! You'll need a Windows with cat14.9 and you also have to brave enough to run my IDE (HetPas.exe) on that system. I can't wait to see your reports that how fast it is on the big cards. :D Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: pallas on January 11, 2015, 03:24:35 AM The compiled bin file should work regardless of catalyst version or operating system, so could you please post a link to the bin file? Thanks.
There is something weird about the sgminer screenshot, are you sure it's working correctly? It shows a single, disabled GPU with id 0, and the share got accepted was from GPU id 1. The diff numbers are also kinda weird. Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: qwep1 on January 11, 2015, 09:21:06 AM I would also tested

Here's what all you have to know if you're willing to test: http://realhet.wordpress.com/gcn-asm-groestl-coin-kernel/ (http://realhet.wordpress.com/gcn-asm-groestl-coin-kernel/) Please send me benchmarks and compiled kernels for various cards!

Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: pallas on January 11, 2015, 10:56:59 PM Realhet, thanks for the capeverde bin, unfortunately I can't use it because it's 32 bit.
I created a bootable win7 stick in order to compile the kernel: it compiles fine but, when run, it says "no target Hawaii" and no bin is created.

Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: realhet on January 11, 2015, 11:47:28 PM Thx for testing! So many errors :S But usually that's how it goes.
"No GCN device found" error. That could be because I can't recognize new cards. I know only these at the moment. 'TAHITI', 'PITCAIRN', 'CAPEVERDE', 'UNKNOWN5'); Importing new names right now. Meanwhile you can select an OpenCL device by uncommenting this line in the code: var dev:=cl.devices[0]; //access device by index (must be a GCN one) The findDevices function can't recognize new cards. I'll repair it now. @pallas: Thanks for fiddling with Win7! :D What does it means by 32 bit code? That has no meaning regarding the GCN hardware o.O But I'm 100% sure that you can't use my Capeverde binary unless you have that chip in the device you selected. ( var dev:=cl.devices[CLdeviceIndex]; ) Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: realhet on January 12, 2015, 12:19:53 AM I've updated HetPas and the groestl_isa.hpas too. Pls download HetPas150111_Groestl.zip.
From now it will start with a list of the cards: writeln("List of opencl devices:"); for var i:=0 to cl.devices.count-1 do begin writeln("Device #",i); writeln(cl.devices[ i].dump); end; It should display something like this: List of opencl devices: Device #0 Target: Cayman Series: 6 Core:880 MHz CU:24 RAM:2048 MB UID:4098 ext: cl_khr_fp64 cl_amd_fp64 cl_khr_global_int32_base_atomics cl_khr_global_int32_extended_atomics ...

Using device: Target: Capeverde Series: 7 Core:880 MHz CU:10 RAM:1024 MB UID:4098 ext: cl_khr_fp64 cl_amd_fp64 ... * core MHz value is not always accurate, use Catalyst Control Center (or ADL) instead! For the GCN cards, the 'Series' must be at least 7. If it fails and it is indeed a GCN card, then I detected it badly, pls report then. My first card is a series 6xxx Northern Islands hardware, it can't used for this kernel. @utahjohn: Maybe it works on 14.7 too. I can't tell that, but I know that it will crash on 13.4 because the kernel parameters are handled differently in that driver.

Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: realhet on January 12, 2015, 01:24:21 AM Yes, that is must be the same kernel that I've copied into the groestl directory next to the groestl_isa.hpas file.
When you compile the original kernel within then groestl_isa.hpas program, it will use the groestl_original.cl kernel. It's Pallas's kernel, except that I hardcoded the workgroup size in it, and did another very minor change. Also I compared the kernel I downloaded from the very first post in this topic: It's the same. Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: utahjohn on January 12, 2015, 01:29:45 AM I did not try running kernel under catalyst 14.9, all I wanted was to generate the kernel.elf to run under 14.7 ... because I run multiple algos concurrently under 14.7 that suffer under 14.9 ...
Also note that I am running sgminer 4.1.0 Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: realhet on January 12, 2015, 01:36:18 AM I tested my kernel only in Cat 14.9
I have no info on how it works on 14.7 When you compile in HetPas it will generate a skeleton kernel binary with the help of the OpenCL compiler. And then the new assembly code will be PATCHED into that. So I don't make the binary from scratch and maybe the 14.7 binary is a bit different than the 14.9 binary and I just don't know about that. (Although life would be so much easier if AMD would be so kind and give us an interface to upload binary program code... But that's not going to happen :D) "Any tweaks you can do with..." Please let's do the test inside the IDE first. Let's compare the original and the new kernel there, as it is perfect for timing. In sgminer we need to play with Intensity and other factors and wait for minutes to get a correct time anyways. So please paste here what you see on HetPas on the right pane after you run the program: I'm interested in this information, and also tell me what card and engine MHz you used: Using new GCN ASM code Kernel binary saved: C:\Work\Groestl\kernel_dump\kernel.elf elapsed: 190.645 ms 13.750 MH/s gain: 3.44x elapsed: 188.281 ms 13.923 MH/s gain: 3.48x elapsed: 188.233 ms 13.927 MH/s gain: 3.48x elapsed: 188.316 ms 13.920 MH/s gain: 3.48x Functional test: RESULT IS OK Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: realhet on January 12, 2015, 02:04:01 AM Thanks!
Well this is kinda bad for a Tahiti :/ Also the times of the 4 kernel launches are weird: On my card it is 3.44x, 3.48x, 3.48x, 3.48x But on your card this is 3.88x, 3.10x, 3.10x, 3.10x On my card the first launch is a bit slow because the card was at low MHz when the test started and after the warmip it became steady 3.48x. On your card the speeds are so random. Your card (at 1150) is 3.68x faster than mine, so everything is ok, you should have see 12.8x gains. Maybe it is a 14.7 issue, I don't know. Everything can change from driver to driver... 1. What if you change workcount form the original WorkCount := 256*10*512 to WorkCount := 256*10*512*10; ? Does elapsed times became are 10x longer? (Functional test will fail, ot's ok, just reset WorkCount to default value after this test) 2. Let's see how the original kernel works in HetPas: just comment out the "#define USE_NEW_ASM_KERNEL" and let me see the times please. If the original kernel works well, then gain must be 3.68. (Thank you for testing so far) -------------------------------------------------------------------- "elapsed: 50.686 ms 51.719 MH/s gain: 12.93x" WOW! THIS IS IT! :D:D:D Exactly what I've expected! Your card is 3.71x faster. What was the error? You accidentally mined while testing, right? Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: utahjohn on January 12, 2015, 02:15:04 AM The last test run I did grabbed 2 cards so divide in half for an average on Tahiti (280x+7950).
Not the gains I was expecting base on you blog ... 3.4x times 18.5 MHs should net me around 62 Mhz vs the 26MHs I'm getting now ... so Tahiti not so great gains but better :) Short of pulling a card physically I don't know how to disable hetpas running all of them ... Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: Star65 on January 12, 2015, 02:34:42 AM I would also tested on 7970 & 280x.
Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: realhet on January 12, 2015, 02:47:15 AM There must be some missunderstandings based on MHs values. So we have to be careful!
On this topic (first post) when Pallas says that R9 280x is 18MH/s he counts it in Groestl hashes. When my program says "elapsed: 50.686 ms 51.719 MH/s" it counts it also in Groestl hashes. Just as Pallas. But when you see MH/s inside sgminer then it must be multiplied by 2 because in SG 1 MH/s = 2 MGroestlH/s. -------------------------- So when you see "51.719 MH/s" is my program then you must see 26MH/s in SG. And when you see 18MH/s on the first post on this topic You must see 9MH/s in SG. Also when I see 4MH/s in my program Then I saw 2MH/s in SG. --------------------------- So the equation is: 2*sgminer Mh/s = Pallas's Mh/s This is because sgminer counts 2 Groesth hash calculations as 1. But Pallas count it as 2 hashes, and I just copied Pallas, then later found out how sgminer calculates. --------------------------- So the Tahiti 26MH/s in sgminer is correct. Please remove the kernel and let sgminer compile it form opencl! If I'm calculating well, then you must see 7-8MH/s with the original kernel. Can you check it please? Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: utahjohn on January 12, 2015, 02:52:13 AM When I run Pallas OCL I see 18.5MHs in sgminer.

Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: Star65 on January 12, 2015, 04:33:54 AM TVM Pallas and realhet for nice work!
7970/280x 1130/300 W7 Pallas kernel in Cat 14.6 - 17.8MH/s Pallas kernel in Cat 14.9 - 7.8MH/s - so 14.9 very bad drivers?! Realhet kernel in Cat 14.9 - 24.8MH/s - 24.8/7.8=3.18x !!! We need realhet kernel (bin) with Cat 14.6 or 14.7 (best drivers perhaps). But I do not know how to do it. Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: utahjohn on January 12, 2015, 05:03:14 AM 14.9 has a piss poor OCL compiler, we've known this for a long time ... Stick with 14.7RC3 for best overall performance over many different algo's.
I guess we are stuck with compiling realhet asm on 14.9 but 14.7 does better compiles for OCL. I am running realhet asm kernel generated with 14.9 on 14.7 catalyst, just a pain in the ass reverting to 14.7 after using 14.9. My Pallas OCL compile was done with 14.7RC3 and works better than OCL compiled on 14.9. Pallas ocl compiled with 14.7RC3 will run normal on 14.9, just don't re-compile it with 14.9 ... Confused yet? hehe @Realhet So the gain of Realhet = 1.40x Pallas stands when comparing to properly working Pallas OCL kernel on 14.7 (Same clocks and Intensity running under 14.7 so a fair compare). Your Pallas reference speed is incorrect in hetpas because 14.9 mangled the OCL badly performance wise. Take a look at performance hit 14.7 vs 14.9 in Star65 post above. Unfortunately some of the "gains" you made may have been just repairing 14.9 OCL bugs LOL but obviously improvement was made somewhere in asm kernel. You need to establish a baseline for your GPU using 14.7 Pallas OCL and see what really made improvements ... I suggest start over and use this first round a learning experience :) You started with code broken by 14.9 compiler as a base ...

I really dislike uninst-inst-uninst-inst to try a new asm version on 14.7 ... For example have it compile Tahiti.elf, hawaii.elf etc. I understand u can only test for your card but with us out here to test other elf would speed process of testing new versions ... DMD Donations : dJrhv4Pp1FXPrQiEp5njx42QrZiuZrbjQ1 Block found and accepted solo mining so your asm kernel appears to be valid :) I'd like you to have a look see what you can do to further improve wolf0's neoscrypt kernel with asm when you get time. 7950 currently doing 278KHs mining FTC.

( var dev:=cl.devices[CLdeviceIndex]; ) Bins generated by sgminer on a 32 bit system will not work on a 64 bit one and viceversa, so I suppose the same is true for your kernels. 4 * 8 (bits) = 32 it's the size of a long integer. probably the sgminer build you are using is 32 bit. my sgminer is old 4.1.0 ... so you main prob is needing hetpas src to run on linux ... Probably realhet coded it for 32 bit; I don't know what changes, maybe the parameter passing part. I hope realhet has time to look into this. I also use version 4.1. Hetpas can't run on linux: I'll try again with the new version when I can access my workstation and make it boot on windows.

Important things to the top: * I slightly updated the HetPas150111_Groestl.zip -> MH/s values are now the same as in SG. * I've updated the main page with benchmark data I've collected: http://realhet.wordpress.com/gcn-asm-groestl-coin-kernel/ * I've uploaded the diamondTahiti binary, so now there are 2 precompiled bins, thank you utahjohn! * My MH/s missunderstanding. Thany you all for the investigations, now I see it clearly. When I tried the groestlcoin.cl on my card on 14.9 and it ran on 2 MH/s. If I convert the 25MH/s from R9 290 down to my HD7770, then I should have got 4 MH/s. And here comes my bad decision: I didn't believed that the 14.6->14.9 changes were so bad that they slowed the kernel more than 2x. Actually it was 2.6x slower than my expectations. And because the algorithm contains technically 2 hash calculations I thought that multiplying by 2 gives me the correct MH/s. But as it turned out they indeed broke 14.9 so badly. So If I ever thought about hating ocl, now I hate it more than twice. To be precise I hate it 2.6x more. :D But on the optimistic side because of 14.9 made an exceptional quality of cr4p out of the ocl kernel, that gave me the false feel of success to continue optimizing, haha. Anyways, I'm happy that it is solved now. * HetPas and Catalyst version When you compile an ASM kernel, my compiler generates a pure binary (and some parameters eg. LDS size) In order to make it run it have to generate a complicated ELF binary image, so it will ask for one from the OpenCL compiler. This small skeleton kernel contains the kernel parameters that you request in the assembly source. For this groestl kernel I supply it a special skeleton.cl (see below in this post). So when CpenCL compiled this small skeleton kernel, my program will patch the binary and other parameters into is. Also cut out every unwanted parts such as ocl, llwmir, amd_il sections. There is even a few kilobytes of zeroes in the ELF just to be compatible with terribly old hardware, I cut that out too. And because I use the current OpenCL system, that's why the produced binary will be only compatible with that kind of hardware. * Binary kernels and Catalyst versions AFAIK when a kernel binary os loaded by clBuildKernei it doesn't check if it is compatible by cat version. Or any other version number. So the binary is quiet transferable between versions. When incompatibility occurs that can be caused by these things: - driver developers changed the ELF file structure (for example they removed some sections: in 13.4 they removed the amd_il section from the inner ELF image. Yes, it is an ELF inside an ELF. :D) This can cause an error ow access violation when loading the kernel. - driver developers changed the way/format kernel parameters are passed. This kind of incompatibility can causes a crash on the GPU. So it doesn't matter that you compile with hetpas on 14.7, I just wrote 14.9 on my blog because I was 100% sure that my program works on 14.9 * "cross compile" option Yea, it would be a nice feature. To do it I need binaries from all hardware, so I can 'dissect' them and maybe find out how to produce them manually. I'm not going to understand the complete binary structure as amd can change it any time, and they must do it when they improve things anyways. I only want to inject GCN binary into the hardware as simple as I can. But with analyzing different binaries maybe I can find out how to change a binary to be compatible with a specific hardware. For example If there are too much hardware dependent options that also depends on the kernel's parameters, then it's impossible to do without fully understanding how parameters are exchanged between the driver and the (specific) hardware. * 32bit/64bit Ok, now I understand. HetPas is all 32bit, so I haven't noticed there can be 64bit ELF's too. I can guess that the Linux driver uses a an API of the OS to access ELF contents and that's why 32/64nit is important... Please compile this kernel to a 64 bit binary and send me: __attribute__((reqd_work_group_size(256, 1, 1))) void search(__global unsigned char* block, volatile __global uint* output, const ulong target) { if(target>0) output[get_local_id(0)] = block[get_global_id(0)]; } * "neoscrypt kernel" Is this similar to LiteCoin? 1 year ago I played with LiteCoin's salsa, It was fun, but I wasn't able to outperform opencl. But in the future I have plans to make a special salsa that will use LDS instead of the slow ram. This will be an interesting experiment as I gonna have to try some assembly exclusive things in order to outperform the original kernel: - To be able to use 64KB lds for one thread I'll have to connect wavefront pairs to share their 32KB allocs with each other. For this I have to know that the current wavefront is running on which compute unit (s_get_hwreg). - synching the two kernels on each CU individually will require some research. (GCN has an awesome global wave synch feature by hardware, so maybe there is something for 'local' too. If not, maybe I can poll GDS) - because only one 'thread' will work actively on a CU, there'll be no latency hiding, so I have to program the kernel in a paralell way (but, no probs, I'll have all the 256 regs...) - By the textbook: LDS throughput is 64x better(IMO it's not) than MEM throughput on a HD7970. So this would be the benefit. - threads in workitems can copy register data from each other. So while I calculate only 1 salsa using the 2*32KB LDS for lookup (lookup_gap=2), I can spread data across more lanes on the wavefront and make calculations in paralell. I've just checked neoscrypt.cl, it's insane :D But if I see it well, the half of it is SALSA. * "Guys! We do not need more optimization!" I've thought about this too. But I think if everyone use better kernels, then everyone will use the same power to get the same profit as difficulty will be harder but mining will require less power. But what if not everyone uses the faster kernel. I think my compuler/IDE is helping in this a lot, as it is kinda user unfriendly :D * Just a question about LiteCoin Do you know that is it worth to optimize it on GPU? Or too many FPGA/ASIC there too? I'm just curious only. I'd like to play that salsa algo, but my free time is running out soon. * @qwep1 ### RESULT IS WRONG #### Something is totally went bad there. Tahiti is tested already, and the 'elapsed' is ok too, but in the memory dump that is garbage. What Catalyst are you using? Is the memory clock setting ok? * kernel_dump\ folder is in the same folder as the groestl_isa.hpas program that you're running in HetPas. * "AVOID 14.9 like the plague" Haha, I'll try 14.12 now.

optimized groestlcoin / diamond etc. opencl kernel Post by: realhet on January 13, 2015, 03:57:29 AM Well that neoscrypt is quiet complicated. I can't even got it compiled as I think it needs more defines than just WORKSIZE alone. Some day I gonna chack it from a closer view as it is interesting...
Now I have Cat 14.12 omega (whatever it is) now. Asm kernel is unchanged, original Ocl kernel is 15% faster than cat 14.9 but it is still way too bad. I've compared your diamondTahiti compilation with my Capeverde one. The differences are not that complicated: - In the ELF's header the 'archtype' field is 3FF vs. 3FD - In the small binary info section (outer elf) 2x bytes are different: 9F vs. 9C - In the small binary info section (inner elf) one byte difference: 1C vs. 1A - In the text ARG section the only difference is the strings: capeverde vs. tahiti So if I collect all these constants/strings I can convert from one to another. But Capeverde and Tahiti are identical chips. It's possible that the binary of Hawaii is much more different. And yet the two binary (capeverde and tahiti) are almost the same, the clBuildKernel() checks for hardware ids and refuses to load it.

On 280x (1180/150) I was able to use my tuning from previous kernel to get 26.0MHs only because it was already maxed out :) Volt modded, vbios modded etc. Info about these techniques is in the thread if you look about ... As far as miner ... sgminer 4.1.0 (sph) is what I use ...

These changes are really pushing my cards now as they normally sat at 50'C but are now over 60'C (They are watercooled). I will put up power usage when i next reboot and plug the power meter in.

Not sure if you can do this to a 290/290x card because vbios likely to be quite different. You will have to do some research before you attempt my method usiing VBE7.0.0.7b.exe it is a video bios editor u can use to change voltages, clocks at board level. If I remember correctly it was only for Tahiti cards ... do your research, then u flash vbios with atiwinflash. There may be programs like msi afterburner but I did my card at low level :) Again check out if it will work on your card before you do it or u can "brick" your card hahaThese changes are really pushing my cards now as they normally sat at 50'C but are now over 60'C (They are watercooled).

Was it a block???? :-D Now let's get serious: I finally have a little time to write some considerations on the ocl and asm kernels. I believe we should pursue the asm path for a number or reasons: - currently the OCL kernel is a little faster on hawaii but not on all other cards and I don't think it can be improved in this respect - the OCL kernel has been tweaked and optimized for months, while the asm one is new so there is probably much more room for improvement - just by applying the first and last round optimization the asm kernel will probably be faster on hawaii as well; I'm sure that Realhet will find other asm tricks to apply - with all these catalyst version problems, the best way to share kernels for the people to mine is by bin files, making the asm version and ocl equivalent (for distribution purposes); better yet would be a miner with all the bundled bin files (takes time) - asm is cooler than ocl ;-) what do you guys think?

1 card the rig pulls 510W at 28.5MH/s so 0.056MH per watt 2 cards the rig pulls 740W at 57MH/s so 0.077MH per watt 3 cards the rig pull 990W at 85.5MH/s so 0.086MH per watt which is about 230 - 250W per card with 0.114MH per watt excluding the system use if anybody can get a higher hash per watt then let me know EDIT Even at that rate with my electricity costs i cant make a profit... Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: utahjohn on January 13, 2015, 10:45:34 AM Wow I got Best share: 702K I'm all for sticking with asm route ... u need to feed your ocl tweaks to realhet and lets maximize asm kernel.Was it a block???? :-D Now let's get serious: I finally have a little time to write some considerations on the ocl and asm kernels. I believe we should pursue the asm path for a number or reasons: - currently the OCL kernel is a little faster on hawaii but not on all other cards and I don't think it can be improved in this respect - the OCL kernel has been tweaked and optimized for months, while the asm one is new so there is probably much more room for improvement - just by applying the first and last round optimization the asm kernel will probably be faster on hawaii as well; I'm sure that Realhet will find other asm tricks to apply - with all these catalyst version problems, the best way to share kernels for the people to mine is by bin files, making the asm version and ocl equivalent (for distribution purposes); better yet would be a miner with all the bundled bin files (takes time) - asm is cooler than ocl ;-) what do you guys think? As I already suggested to realhet "cross-compile" to generate bins for all arch we support is possible, he needs our bins created on each arch to dig out minor diffs between bins. Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: mitache365 on January 13, 2015, 02:59:31 PM Can I ask what software you are using to change the values as I'm using msi after burner 4.1 but it wont change the memory clock and the core clock is always lower than what I set? These changes are really pushing my cards now as they normally sat at 50'C but are now over 60'C (They are watercooled).

We do not need more optimization!" Just as I thought also, there has not been a widespread migration to new kernel :) Difficulty for newbs to set-up properly, combined with falling BTC value make direct mining less attractive to the "Dumpers" ... Diff is back to a reasonable range again as miners drop out of game ...I've thought about this too. But I think if everyone use better kernels, then everyone will use the same power to get the same profit as difficulty will be harder but mining will require less power. But what if not everyone uses the faster kernel. I think my compuler/IDE is helping in this a lot, as it is kinda user unfriendly This is good for those of us who stick with it :) BTC will recover eventually, I am a long-term DMD holder anyway :) Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: pallas on January 14, 2015, 09:13:04 PM Utahjohn: true!

I don't really have a grasp on parallel processing and all the nuances of register usage on GPU ... looks like the ball is in your court Pallas. Hopefully Realhet returns to continue on this project. Found this, looking thru it now ... http://developer.amd.com/wordpress/media/2012/12/AMD_Southern_Islands_Instruction_Set_Architecture.pdf Wish I had a printed book of this reference ... wonder if one could order it online, I have no printer ... This is what I was looking for :) Wow a lot to grasp :) Nice, even gives opcodes, I bet this is reference realhet used to build hetpas :) In his dev thread he mentions u can inline an instruction opcode for any that are not supported by hetpas assembler. The opcode tables for generating instructions manually are in the ref manual :) Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: utahjohn on January 14, 2015, 11:47:44 PM @pallas
will you be able to do your best first/last pass implementation in ASM? Looks like realhet has moved on to another project ... Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: realhet on January 15, 2015, 02:28:11 AM Hi,
"- asm is cooler than ocl ;-)" Haha, yes! And ocl needs black magic to optimize, asm just does what you tell it to. "Nice, even gives opcodes, I bet this is reference realhet used to build hetpas Smiley" I remember, I had a work that time when 7970 came out. I just got one in 2011 december. There was no manual for more than half a year, but the disassembler worked well. So I decoded the instruction set using the disassembler. I even found some undocumented ones that way. It was fun. But for some unknown reasons this approach is broken because 1-2 years ago the disassembler is just does nothing when the .elf is a binary only .elf (this is the case when you use my assembler). Some tips: - Use Ctrl+Space in the IDE! It's like Intellisense/codeInsight. (Just start typing v_something!) - Press F1 on any instruction, it will show a mini help. - You can DD anything that doesn't implemented. (eg. "dd $12345678, 0x74732921, 1234" emits 3 uints into code) - Disassembling small opencl programs is a good source of knowledge. Also this is the 'documentstion' on how to specific set of pass kernel parameters. "Looks like realhet has moved on to another project ..." Yea, I have to continue my job soon, as my free time runs out. I'm only planning to experiment with a bit of 2D rope physics. But whatever, now I'm in a Red Alert 2 'project', haha :D Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: pallas on January 15, 2015, 09:18:27 AM Oh, that's a pity you moved away...
Not sure I like the idea of learning another asm, even if it's very cool! I understand the first and last round optimizations are boring to do, but could you please, before leaving us, fix the problem with multiple cards? Where card 0 doesn't provide any work unit while card 1 works fine? Thanks! Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: utahjohn on January 15, 2015, 09:26:14 AM This one is going to take a lot of learning for me (I'm 53yo LOL learning takes more time for me hehehe) ... I'm going to copy asm src to flash drive and print at apt complex office so it's a bit easier for me to follow through. Can u send me your latest greatest fastest OCL and I'll get that printed too ...
Funny u can only get 1 card to run, I have 280x as card 0, 7950 as card 1 and they both run kernel fine ... Just an after thought, I have not tried with single instance of sgminer controlling both cards, I run an instance of sgminer for each card individually, so I do not know if this problem affects me ...

I understand the first and last round optimizations are boring to do, but could you please, before leaving us, fix the problem with multiple cards? Where card 0 doesn't provide any work unit while card 1 works fine? Thanks! I built my bin as posted using Hetpass. Two machines. Two 7950s reference cards in one. And a Dualx 7950 in the other. All Sapphires. I use Sgminer 4.1 the original if you will. Not sgminer 5.1. Too many bells and whistles. Hetpass said these cards should do soo many hashes and it is correct. I run two cards in one machine with out any problems. ....... On my machine, card 0 hashed fine but no work submitted (WU=0). Card 1 had normal WU. I'm using 4.1 as well. Never had this problem with any kernel before.

I have groestl code from smelter (first GPU miner for quark). May be it have some tricks for your work. It was rather fast on radeon HD 5xxx series. But it is not adapted for sgminer and I have no skills to do this job. Code: #define CONSTANT __constant Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: pallas on March 05, 2015, 08:45:32 AM Pallas, Are you planning on adding myriad-groestl support in the future? If not, could you explain why not? Is it because your groestl kernel is already faster than the myriad-groestl? Also, are you planning on putting your work on github? Again, if not, could you explain why not? It seems to me that both are important ways to further your efforts and establish your reputation. Best regards as always. HR Myr-Groestl must do SHA256 as well, IIRC - of course pure Groestl is faster. myr-groestl should be faster because its has a single round of groestl (14 iterations) + sha; groestlcoin is groestl + groestl again, so slower. it's just that I do not have enough free time to work on all these algos.....

I must say that NV has better instructions to do it: __byte_perm(x, 0, 1010)>>s: this could be emulated by an AND and a MAD24 and az SHR. 3 instead of 2 cycle. __byte_perm(x, 0, 3232)>>s: SHR, MAD24, SHR also 3 instead of 2. __byte_perm(x, y, 5410) : SHL, BFE 2 instead of 1 instr. (Even the Intel SSE has many instructions for these things since ages :S) And there are lots of bitwise logical instructions where NV is 2x faster because NV has a 3 op logic instruction with all the possible 16*16 logic operator combinations. There are shuffling between 4 lanes: That is not a problem on GCN with ds_swizzle, otherwise it needs LDS on OpenCL. I've just checked the GCN 1.3 ISA manual and (at least there) I haven't found byte_swizzle and no 3 operand logic instructions either. Anyways, It would be interesting that how this totally different approach can perform compared to the table based one.

This kernel is much bigger in size so you can't just copy some good lines of code and it runs faster. Furthermore some of the optimizations I made in the past, make it more time consuming to apply some apparently simple hacks. Wolf0 I'm sure you know what I mean ;-) Still there is room for improvement, I have some ideas, but the question is: when the profit is gone, and the fun is gone, is it still worth?

Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: realhet on May 17, 2015, 10:21:24 AM Hi,
Have you checked the new GCN3 ISA manual? http://amd-dev.wpengine.netdna-cdn.com/wordpress/media/2013/07/AMD_GCN3_Instruction_Set_Architecture.pdf (http://amd-dev.wpengine.netdna-cdn.com/wordpress/media/2013/07/AMD_GCN3_Instruction_Set_Architecture.pdf) It has some really useful things like: - Bytepermute (no more shifts and masks) - VOP_DPP: It actually does 2 ds_swizzle in the instruction in no time, so optimizing a single thread for 4 lanes costs no more cycles. - VOP_SDWA: access a word or a byte in the 32bit inputs and in the output too. (again: no more shifts and masks) - S alu can write memory No 3 op add, and 3 op bitwise, though. And they altered some instruction encodings, so I guess my asm will crash on GCN3 immediately. :D Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: MaxDZ8 on May 18, 2015, 03:44:15 PM That's some truly slick updates!
I was indeed planning to do full AES round without t-tables as the amount of masks are nonsensical. I had the impression the SALU was immensely updated for Tonga given it takes much more VGPRs on the analyzer. I wonder how to trick the CL compiler in emitting this code. But most importantly, what are they waiting to just make an AMD_GCN_swizzle extension!? Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: realhet on May 21, 2015, 12:31:48 PM It doesn't seems like they are implementing gcn specific goodies on the current compiler stack. It's kinda bloated, and AMD_IL awaits for it's replacement since 7970 came out. I'm sure in the upcoming HSA language there will be much more GCN things implemented (except the separated V and S programming).

Title: Re: [ANN][GRS][DMD] Pallas optimized groestlcoin / diamond etc. opencl kernel Post by: pallas on July 03, 2015, 08:31:30 AM Wolf0 created a faster Tahiti binary and posted about it in the groestlcoin thread:
I have a faster Tahiti binary than Pallas' for Groestlcoin - works on DMD, too. The usage is the same as his binary; I should have more info later. Get it here: https://ottrbutt.com/miner/wolf-groestlcoinTahitigw256l4.bin it is indeed faster and works flawlessly. usage: just rename it over the old one and make sure you set worksize 256 for that card; you can get a bit more hashrate by using 2 or 4 threads.

R9-280x - 23Mh/s 1090Mhz Clock Stock Memory Clock 0% Power Limit My only question is that I was never able to find a working download link for your .cl file, I just replaced the .bin file with that from Wolf. Not sure if I would get better results having your .cl file as well but if anyone can provide a working link to that, it would be most appreciated. Given my confusion on how to get started, here is what I did in case anyone else runs into the same problem. 1) Download SPH SG-Miner 2) Run it and connect it to a pool, where it will generate a .bin file in the root folder of the Miner 3) Download Wolf's Tahiti Binary (https://ottrbutt.com/miner/wolf-groestlcoinTahitigw256l4.bin) 4) Place the Binary file into the root folder of the Miner, rename it to that of the one in Step 2 and delete or replace the original Another question I have is if I can solo mine using this?
