[ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX]

[cbuchner1]

I have done some undervolting and overclocking to see what happens with temp and hashrate.

core i7 920 @ 3.0 GHz, 6 GB RAM @ 1600 MHz
GTX 580, 3 GB 384 bit, Core: 844, Mem: 2055, Shader: 1688
-i 0 -H 1 -C 1 -l F16x16
307.11 khash/s | 74 °C

Would it be helpfull if I try to compile CudaMiner myself for Fermi Kernel?

compare with 2013-12-10 release for reference..
things that changed:

cuda 5.5 instead of 5.0
compiled with -arch sm_20 and maxrregcount 63 instead sm_10 and maxrregcount 124

not sure yet what caused the extra heat. Maybe the default -H 2 option instead of -H 1 previously

I have a GTX 670 that can run at 250khash/sec - 300khash/sec, but it's running my card too hot.

Is there a configuration so I can run it at 200khash/sec?

At this rate my card just throttles after a few hours and hashrate plummets.

I plan to add a percentage scaling for mining intensity as well as temperature throttling in software...

That would be amazing. I'd be lost without cudaMiner.

[M.Winter]

compare with 2013-12-10 release for reference..

I downloaded  2013-12-10  release, but the speed is exactly the same.
(maybe +1 khash/s, but mostly the same ^^)

Any other old releases i should try?

Edit: okay, seems like +3 and sometimes +5 khash/s more with '2013-12-10'
It also seems like it is getting faster

Edit 2: temp is down to 68 °C (from 74 °C) with  '2013-12-10'. Nice.
I am gonna stay with that version for now.

I think we're basically done other than micro-optimization.

Do you have any predictions for Maxwell?

Also, cbuchner, I tried asking earlier but I didn't see a response. Do you have a BTC address?

try either K14x7 or K54x4 that seems to work pretty well on a 670 I have, auto not as much

[paulus51]

any one please help me with this :
i have a EVGA GT610 2GB card and i dont know how and witch settings i should use.....

please help needed here.......

I do not know enough about Maxwell internals to make any guesses about its performance.

yay, I have a BTC wallet. 16hJF5mceSojnTD3ZTUDqdRhDyPJzoRakM

Have you got the latest nvidia drivers? I had the same when on old drivers.

[M.Winter]

My mining pool went down while I was mining with CudaMiner.
It was down for 17 Minutes and then came back online.

Just want to say, that CudaMiner did a great job and it started to mine again as soon as the pool was back online.
Well done. Timeouts are working great and it did start without any high delay or problems.

Hey first of all thanks for your effort in making cudaminer

well, when I had cuda-5.0 everything worked great but I updated it to 5.5 and now I can't compile

/usr/local/cuda/bin/nvcc -O3 -Xptxas "-abi=no -v" -arch=compute_30 --maxrregcount=63  -o spinlock_kernel.o -c spinlock_kernel.cu
UNREACHABLE executed!
Stack dump:
0.   Running pass 'NVPTX DAG->DAG Pattern Instruction Selection' on function '@_Z28spinlock_scrypt_core_kernelBILi3EEvPj'
Aborted
make[2]: *** [spinlock_kernel.o] Error 134


Its the same error for 12-10 and 12-18, any ideas?

Driver version 331.20
I have 2 miners

miner 1: 4x tesla k10
miner 2: tesla C1050 and tesla C2050

And both are debian wheezy

weird. the 12-18 is known to compile on  CUDA 5.5. For this to work, I changed the outdated Spinlock Kernel to use compute_12, and I had to lower the shared memory use (by limiting the max. no of warps to 12 I believe). No idea why it still uses compute_30 for you.

try running ./autogen.sh before configure and make, maybe?

still, these 17 minutes are lost time. I really want to integrate some failover. Just the day I started mining on hashco.ws they suffered some bad outages (DDOS?). Failover would have helped a lot.

Its something wrong with my system, freeze when run device query for example....

about the spin lock maybe I messed up the sources  will download again and retry

I had this problem before

Auto-tuning crashed when I ran with more than 1 card, try running with -d 0 just to get the best config
Then run with -d 0,1 -l <best config from auto-tuning>

[cbuchner1]

btw can you upload it to github (for example), every time I download I have to dos2unix all files

do a search for cudaminer on github and grab it from there. It even has a few (so far unreleased) improvements in it.

Maybe the source tarball in the 2013-12-18 version doesn't yet have the necessary compilation fixes for Linux,
so that's why your cuda compiler still crashes on the spinlock kernel.
