CCminer(SP-MOD) Modded GPU kernels.

[t-nelson]

I remember getting the number of SMM/SMXs in the CryptoNight miner... can't remember how, though.

Yep. TSIV's Cryptonight ccminer complains whenever the blocks/threads (don't recall which one now) is not a multiple of the SMX/SMM on the card. IIRC, it does this also accurately for cards that did not exist when it was released, so the approach is not LUT based.

Right - I can't remember if I wrote that or not.

Nice, I'll have to dig into these APIs a bit deeper once I get all of the cleanup I have planned done.

@t-nelson: extending the invite that every cuda miner developer has probably received at some point:
Some of the usual suspects (both developers & community) hang out at #ccminer @freenode. It is not the most active channel in freenode, but it is a great place to exchange ideas with the other developers and the few of us there always try to help each other out (testing, etc).

In case that IRC is not your usual thing, maybe webchat will get you there: #ccminer webchat

TPB52 7 is best for mining. My gtx 980 make 11.2-11.6 Mh. 960 gtx make 6 Mh. Super!
For rig (2x980+1x960) hash is 28500!
PS. It is LYRA2v2! +100 git 1052 works!

Would you share your command line?  I am running a 1x980 and 1x960 in a box.  I have the hardest time to configuring both together.

Thanks

All works by default, card OC'd to 1380 Mhz. Ccminer recompiled with TBP52=7 setted in lyra2REve.cu. Thanks to _SP!

[bathrobehero]

frames? ... i build them custom ...

the frame ( 1.5mm square aluminium tubing ) - edge connectors - screws and lugs - angle iron ( 90 degree edging ) ... all this comes to approx $70.00aud ...

but initially i had to buy the cutting and measuring equipment as well as the files and mallets ( yes plastic head mallets - not hammers ) ...

parts alone - not counting labour - if you are looking at adding teh countless hours to design the thing in the first place ...

prototype 1 - prototype 2 and now prototype 3 is probably the design we are going with ...

hope that helps bathrobehero ...

Thanks, it does. I have similar prices but personally, I don't find that to be worth it and I'm much more comfortable spending that ~50 USD into better PSUs.

I must say that I didn't have any problem benchmarking amd cards: if the room was hot, I'd put the fans at high speed, run the miner and wait a couple minute to stabilize, and that's it. I could make 100 changes to a kernel in a day and check them all, accurately.

On nvidia I have throttling problems I can't easily fix (the cards reduce clock speed in a number of situations I just can't predict), overclocking/downclocking is more difficult as the cards tend to change clocks by themselves, and the hashrates fluctuates wildly, and even changes between ccminer runs.
The rig is headless so I only have nvidia-smi to work with, and it can't set the fan speed.
So when I make a little kernel speedup, I spend more time benchmarking it (to be sure it's indeed an improvement), than making the improvement itself :-/
Maybe there are some nvidia-smi settings to make it more stable?
Or maybe on windows it's different...
Finally I may need a workstation with a nvidia as main card, and work on it.

You should probably disable boost in the bios of the card. Or even set custom fan speed/clock speeds if you want.

It may be time for me to use multiple work items on one Lyra2 execution... but I'm worried the increased memory accesses for the matrix (which I've worked to eliminate) will eat me alive.

In my latests fixes I added more memory accesses and speed..

Perhaps this is the opposite of what you are supposed to do when doing a modded kernal, but I think it was fun..
Only latency wankers working for NVIDIA it seems...


Still slow though. You know the opensource is slow, because the market makes it not profitable to mine.

Your optimized kernals might end up here wolf0, And I think they can afford to pay you enough:

[hashbrown9000]

@myagui, yes you are on point about enabling the fake X screens on multiple cards, (which then allows you to set fan speeds, mem clocks and core clocks with Nvidia X Server settings program).  Details here: https://litecointalk.org/index.php?topic=16800.msg266088#msg266088.

I am running an older driver (346.59 with CUDA 6.5.19, LUbuntu 14.04), so the attribute names and procedure may be slightly different.

and anyone know if there's a way in linux to get this card to overclock?

LINUX OVERCLOCKING--

You will need to do some web research.  It depends on your Linux drivers.  HashBrown has written and posted on this topic in the Kopiemtu blog thread, his work is for slightly older drivers.  Only a few posts back in this thread, I mentioned how to use nvidia-xconfig to set CoolBits.  This is possible with the very latest nVidia drivers.

Frankly, I would write a tutorial but I haven't updated my drivers and actually done it myself.  My system is stable, my 970 cards are getting 16.5-17Mh/s on Quark as is.  I have been reading all over the web about Linux overclocking, though.  Useful search terms include CoolBits, nvidia-smi,  nvidia-xconfig.  The very latest nVidia drivers simplify things; some of the posts that are 2-3 years old are outdated and involve more complicated configuration editing.

Apparently, the "nvidia-xconfig" command will write out a config for your system, but only with the latest drivers.       --scryptr

I have a 9800 GTX+ card, the top of the line for the series.  It mined script at 14kh/s using CudaMiner.  My 550ti got 90kh/s, and the 520 that came in the system got 21kh/s.        --scryptr

COMPUTE 1.0 -

CCminer works with compute 2.0 and up, depending on the coder who wrote it.  A 550ti is "Compute 2.1".  SP_ codes for compute 5.0 (Maxwell, 750ti) and later. A 9800 is Compute 1.0.  So, no luck, for any practical mining with the 9XXX series.  You could play Tomb Raider with ease, though.         --scryptr

awesome, thanks for the leads. Hrm, forgot the 950 needs a 6 pin power line...

[frazier34567]

Noticed something interesting on my 6 card EVGA 750ti SC miner.  When I use -C I get about 39250 Kh/s (No OC).   If I do not use it I get about 39000-39190 Kh/s.  Now if I mine Axiom with the nicehash cpu launch miner with just one thread running (No -C 30% load on CPU).  https://github.com/nicehash/cpuminer-multi/releases  I get 39235-39240 Kh/s  I am running a Intel i3 4330 (dual Core 4 thread CPU)

This is with 1.5.66 commit. 1056  Cuda 6.5 Windows 8.1 Pro Driver 355.60

 sp  could you please put the http protocol back in the source code. I can't wallet mine. And djm lyra2v2 is the same. thx    

Well I still can't wallet mine with latest versions.  http protocol failed.

Does it work in the 1.6.6 fork by tvpruvot?

I don't know sp . Do you mean 1.5.64   ?

my version works with solomining (and was tested with...) so it is probably on your hand (wrong rpc port, username or password)

I know someone who is using your older version because the new ones won't work solo mining.
maybe cuda build app files have changed ..because about the same time sp releases aren't working either.
I'm going to try an older version of lyra2v2  of yours djm.

older ? there are 4 releases which are mostly bug correction (and compatibility issues) and none of these changes are related to solo mining.
all are there, and all are working: https://github.com/djm34/ccminer-lyra/releases

regarding solo mining, I don't know what is the default vtc port, I use a custom config file to define which port are used and some other settings.
(make sure as well, that you are using the latest wallet...  )

also I am using --api-bind 0 (as it becomes problematic when there are several instances) and obviously don't use the same port for api-bind and the wallet

edit: there was a changed pushed by pallas to bmw256, however I don't think it would break solo mining, you can probably test that with testnet

Ok thank you djm. The other person had to use your version before ver4 to make it work.
But still something happened , related?, to solo mining about the time your oldest version was released I think. Will try your oldest tomorrow.
But to clarify ... sp r43 solo mining a coin works....now with exactly the same bat file and using r55 or r60 or r62 it won't work.
Will try again tomorrow. thx

I have tested solo mining Quarkcoin with release 64 now on my system.
Command line: ccminer -O name:password -o http://localhost:8372 -a quark --no-gbt
This happened:


ccminer actually crashed:

Unhandled exception at 0x00C99824 in ccminer.exe: Stack cookie instrumentation code detected a stack-based buffer overrun.

SOLO MINING VERTCOIN--

The question was asked a few pages back about solo mining VertCoin.  I was able to set-up and mine VTC with CCminer release dot 66 on Windows.  Here is what I learned:

     1) The VertCoin wallet looks for a file called "vertcoin.conf" BY DEFAULT on startup.
     2) The VertCoin configuration file "vertcoin.conf" only needs to be minimal.
     3) The folder to place "vertcoin.conf" is in ...appdata/roaming/vertcoin in windows, under the login user files.

Here is my vertcoin.conf file:
=======CUT LINE=======
server=1

daemon=1

rpcuser=username

rpcpassword=x

rpcallowip=127.0.0.1
=======CUT LINE=======

Notice that no ports are mentioned here!

Here is my CCminer command line:

ccminer.exe -c solo-vtc.conf

I use a configuration file to launch.  Here is my configuration file, solo-vtc.conf:

========CUT LINE=========
{
   "url" : "127.0.0.1:5888",
   "user" : "username",
   "pass" : "x",
   "algo" : "lyra2v2",
   "devices" : "0",
   "intensity" : "19",
   "cpu-priority" : 5,
   "cpu-mining" : "true",
      
   "api-bind" : "0",
   "statsavg" : 20,
   "quiet" : false,
   "debug" : false,
   "protocol" : false
}
========CUT LINE=========

Leave the cut lines out, but don't forget the curly brackets.  THERE IS A PORT HERE!  It is the default RPCport (5888) for VertCoin.  You may want to lower the cpu-priority or intensity for your hardware.

It works for me.       --scryptr

EDIT:  MINE ON A LAN--

For those of you that have a "work" or "home" computer with a wallet, and one or more mining rigs, the setup is a little different.  In "vertcoin.conf", set the "rpcallowip" line to "rpcallowip=192.168.1.*", or similar if your local net uses a different configuration.  The asterisk is a "wildcard" that will allow any rig on the local net to link to the wallet on the home computer.  On the mining rig(s), for the url use the physical, numerical address of the home computer, i.e. "192.168.1.111:5888".  If you are using a command line only, use "ccminer -a lyra2v2 -o http://192.168.1.111:5888 -u username -p x".  You can get the lan address of the home computer from your router; I set this example to "111".

There may be a looong pause on miner lanch, but if you don't see red, just wait.  Hash results for your cards should appear within 90 seconds.  Of course, you can tweak the command line with performance flags.  If you also mine with a card on the home computer, make sure you use the lan address for the wallet, just as in the previous paragraph, not "localhost" or "127.0.0.1".  There is still a long pause before hash results.


Local GTX 960 card on Win 7 work computer and Linux 750ti mining rig on LAN


The cards will hash until an "accept" is received.  Then your wallet will be 50 VTC fatter.       --scryptr

Or maybe on windows it's different...

Yeps. On Windows it is extremely simple to set fixed clocks, fans, overclocking, so you can easily have a "benchmark platform".

With a headless Linux system I don't think there's any solution for fixed fans yet, others might know differently. I previously had fixed fans and clocks on Linux, but I perfectly recall that I specifically had to configure/attach a monitor in order to get that working at the time.

to set the fan on linux just test this

https://gist.github.com/squadbox/e5b5f7bcd86259d627ed

Thanks, but I fear it needs a monitor or the x session will not start... Or will it?

NOT ANY MORE--

If you have one of the latest driver packages, you can use nvidia-config to enable cards without monitors to be adjusted:

"sudo nvidia-xconfig -a --cool-bits=28 --allow-empty-initial-configuration" (Source: https://bitcointalk.org/index.php?topic=826901.msg12279696#msg12279696)

The numbeer "28" is a bitsum that signifies clocks, fanspeed, and power controls.

This was in this thread, earlier.  I think that "-a" and the longer "--allow-empty-initial-configuration" are equivalent.

--scryptr

-a is equivalent to --enable-all-gpus, which configures an X screen on every GPU in the system.

I've tested the sctipt on Ubuntu 14.04 with two 750 Ti.

To set fixed fan speeds

Code:

sudo ./cool_gpu2.sh 72

To reset to default

Code:

sudo ./cool_gpu2.sh stop

[hashbrown9000]

i've stayed with older nvidia drivers because my system is stable.  can anyone that is running the newest drivers under linux tell me if nvidia-settings works over SSH?  that was one big failure of the older drivers. all configuration of setup and overclocking had to be done locally with a monitor attached, and then the rig could be deployed headless.
