CCminer(SP-MOD) Modded GPU kernels.

[joblo]

is there a gtx 760 kepler kernel code for this miner?

You can change the config to compile for sm3.5.

I tried that, it didnt work.  ccminer just told me that the compute version is incompatible.

760 is 3.0. Ooops.

actually it could be 3.0 (not sure when the 760 has been released... but 3.5 is only for the titan/780/780ti)

and, when I try and mine with my gtx 760, the sm 3.0 model of ccminer with neoscrypt support says that the algorithm cannot be mined in sm 3.0 devices.  I have the latest cuda and drivers installed (automatically installs).

@Sp any updates of this kernels,I'm donator of this algo's )) decred i have rev3. don't remember others ))
3. 0.1BTC: Spreadcoin +10-20% (with full sourcecode / linux compatible)
4. 0.1BTC: All nicehash algos optimized. 0-7%
5. 0.1BTC: decred +10-21%

The may 2015 release(release 9 or 8 ) does around 5mhash with oc on the 970

Release 7 which I assume you're talking about does 4.35 Mh/s on stock (970 WF3OC) and 4.8 Mh/s with +150 Mhz OC (1465-1478 Mhz). Above that it's bound to crash in a few hours.

where to download?

yeah, that's normal (sort of... I never been able to get a pre-3.5 implementation working...) , only 3.5 and higher are supported for neoscrypt.
Actually you could get it to work with opencl and sgminer

also if ethereum go pos, another big coin will emerge, probably decred, so a pump there is not so unexpected in the near future
the money will always move in way or another and diff will follow

Investors don't just decide to invest in a new coin when one goes PoS in order to feed miners money. If Eth dies, either by bottoming out or PoS, miners are more then likely SoL. Decred and Vanilla are the next closest things.

Before Eth it was Dash and Dash has been private kernels/ASIC for quite some time... three months ago we were making $.50 profit on a 970, today it's $6... This is definitely a high point and it shouldn't be expected it'll stay this way.

money does not vanish, they always float one way or another, there will be always a strong altcoin, like it was litecoin, then doge, then darkcoin, then blackcoin, then ethereum, then it will be decred or a ethereum clone or a new thing, this section will never die, this what i've understand

Putting aside how unlikely it is that money will always be static in cryptos... It doesn't stay the same between 'altcoins'. Investors don't decide to invest based on the needs of miners. It's based on profitability and how much they believe in the coin. Believe it or not, there are a lot of coins that aren't GPU mineable... including this coin called Bitcoin.

Looking at the past, your logic completely breaks as three months ago there wasn't anything close to as profitable as it is right now in the GPU mining sector. Before that, there were about six months ago (still not as profitable, but profitable), before that more so.

As I mentioned before, GPU mining hash has grown about 30% in the last two weeks... Maybe closer to 50% as Eth has gained another 300Mh since then.

The x11 algo used to have 500GHASH.
The Quark algo used to have 200-300 GHASH
the lyra2v2 algo used to have 100GHASH etc..

People move their rigs to mine etherum. If etherum go pos, they will move their rigs back to what they used to mine.

ps. The quark algo is now paying above 0.5BTC/GHASH @ http://www.zpool.ca (0,015234BTC / Day ($6.4))

The 980ti should do 30MHASH with my buyable private miner on the 980ti with a little overclock. (0.1BTC)
The quark opensource kernal does 2.5MHASH on the r9 280x

Yup and they'll get smooshed. There is definitely a increase in hashrate due to Ethereum, the 50% increase in hash isn't just people moving away from other coins. That's what happened at first. Now it's people buying new hardware.

Yes, July 2015:

Just a tiny increase from release 8 this time

I apologize, I just realized that I did receive release 8 and 9 back when they were distributed but I missed it for some reason.

I tried that, it didnt work.  ccminer just told me that the compute version is incompatible.

actually it could be 3.0 (not sure when the 760 has been released... but 3.5 is only for the titan/780/780ti)

the gtx 760 was released on june 25th, 2013

and, when I try and mine with my gtx 760, the sm 3.0 model of ccminer with neoscrypt support says that the algorithm cannot be mined in sm 3.0 devices.  I have the latest cuda and drivers installed (automatically installs).

yeah, that's normal (sort of... I never been able to get a post-3.5 implementation working...) , only 3.5 and higher are supported for neoscrypt.

I might be able to help. Is it the fucked global memory accesses in the ugly, retarded homebrew KDF thing?

hmm ? actually in the nvidia version it is the whole "long" rotation which I haven't been able to rewrite with the 3.0 command (even though it should have worked, it always failed to produce a result... that was the case before the optimized code already)

Hi guys

I have a GTX 960. What is the expected hash rate? Also, which version should I download for Windows 10 and where can I get it? I have been looking at this thread for a long time, but can only see download links in the first couple of posts.

Thanks.

[tbearhere]

Etherum will hardfork, but dwarfpool has  57% of the network hashrate. What if they refuse to upgrade the wallet. Then there will be no hardfork..

Etherum

Nethashrate: 1 303 320 GHASH
Dwarfpool:     740 872 GHASH

In the early Dash days (darkcoin) many pools refused to upgrade their wallets, because the payouts to the miners was reduced.

Where are the list of pools sp?
thx

hashrate for what algo? i think you cna do fine with etheruem and 15mega or decred around 1GB, and windows 10 is not recomended, because even if they fixed the lower hashrate, still it's not on par with windows 7 hashrate, for ethereum i'm talking

[sp_]

I have done some tests. I expect the final decred mod #4 will be able to do 3.1 ghash on the 980ti. The 750ti will gain around +30mhash +37MHASH from release #3

[sp_]

Ok. I have found away to do the optimal decred kernal now.
http://stackoverflow.com/questions/15842507/passing-the-ptx-program-to-the-cuda-driver-directly
So I will generate the ptx assembly with the midstate data included in the instructions. Then for every time the midstate is changing, I recompile the kernal runtime with the API calls described in the article.
To estimate the speedgain you can replace all the constant mem access with contstants in the 1.7.4 code.. Release #4 will be optimal..

Interesting technique.
But I doubt you'll gain even 1% from it, likely less.

you will, because some of the first rounds will be gone.. (instructions are removed since they work on constant data..) You can try it. replace the d_data[0]...d_data[23] with constant data 0x01234567 etc; make sure every constant is different from each other.. Compile,read the ptx, and count the lines before and after.

Then you don't have 14 round blake kernal. but a 12 rounds blake kernal that only works for one midstate. And solves the 14 round blake problem for one given midstate.

I just perfomed the test in cuda 7.5 The self modified code decred kernal is only using 28 registers. (Down from 80). The ptx Assembly linecount is Down 200 lines from sp-mod #3 (10%)

On the gtx960M(release #4 is 8% faster than release #3) Edit:  I think I can tune it bether, because the register Count has dropped. 512Threads per Block instead of 256 --->+25mhash etc

I kinda doubt there's a documented and stable, supported method of doing so...

You can do it safe:

1. Put the compiled cubin in a ramdisk. (virtual memory drive)
2. Poke the constant values with the cpu directly in the file. (the locations can be found with disassembly and the offsets might change from compiler to compiler (cuda versions) )
2. call the cuda api call cuModuleLoad

https://www.cs.cmu.edu/afs/cs/academic/class/15668-s11/www/cuda-doc/html/group__CUDA__MODULE_g366093bd269dafd0af21f1c7d18115d3.html

If the cubin files are Equal on Windows and Linux I could make a Linux Version of release #4

Nice news! i`ll be waiting #4 ...
