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

[maxim000]

Why do you want to compile cudaminer. Almost all the algorithms have been ported and optimized in ccminer

I couldn't find scrypt-jane in ccminer.
Does it have implemented this algo for yacoin, ultracoin etc..

Tpruvot's cc miner supports script-jane

but it crashes if more than 1 card

[Epsylon3]

i guess you have 2 different cards, so the scrypt settings should be set for both with the comma "," separator

never seen the problem... but its also true i dont mine scrypt ,) i hate this algo and coins using it...

I'm trying to compile tpruvot's ccminer, but make breaks. Something about
Algo256/cuda_blake256.cu(28): warning: expression has no effect
Algo256/cuda_blake256.cu(28): error: expected a ")"

I'm testing this with a Quadro K2000M (which is a compute 3.0 card), nvidia drivers 346.72 and CUDA 6.5, on Xubuntu 14.04.

A few lines before the error I can see things like
/usr/local/cuda/bin/nvcc -gencode=arch=compute_50,code=\"sm_50,compute_50\" -I/usr/local/cuda/include -I. -O3 -lineno -Xcompiler -Wall  --ptxas-options="-v" --maxrregcount=128 -o Algo256/cuda_groestl256.o -c Algo256/cuda_groestl256.cu

compute_50 is not correct, right? Could this be the reason? In configure.sh there are a few commented alternatives for different compute cards, like

Code:

# possible additional CUDA_CFLAGS
#-gencode=arch=compute_50,code=\"sm_50,compute_50\"
#-gencode=arch=compute_35,code=\"sm_35,compute_35\"
#-gencode=arch=compute_30,code=\"sm_30,compute_30\"

but I can't seem to find the correct syntax to add one of these to CUDA_CFLAGS, which is by default

Code:

CUDA_CFLAGS="-O3 -lineno -Xcompiler -Wall" ./configure CXXFLAGS="-O3 $extracflags" --with-cuda=/usr/local/cuda --with-nvml=libnvidia-ml.so

I guess all the "" confuses me. Could anyone help with this please? Thanks.

@ngdias:

Not that I know much of compiling, and less with Linux. In any case, I think you'd be looking to change the target architecture.
The target selection is on the following file/location:
https://github.com/tpruvot/ccminer/blob/windows/Makefile.am#L79

Code:

nvcc_ARCH  = -gencode=arch=compute_50,code=\"sm_50,compute_50\"

#nvcc_ARCH += -gencode=arch=compute_52,code=\"sm_52,compute_52\"
#nvcc_ARCH += -gencode=arch=compute_35,code=\"sm_35,compute_35\"
#nvcc_ARCH += -gencode=arch=compute_30,code=\"sm_30,compute_30\"
#nvcc_ARCH += -gencode=arch=compute_20,code=\"sm_21,compute_20\"

You can just comment the current selection (compute 50), and uncomment the desired one.
Good luck!

I wonder if somewhere exists ccminer for neoscrypt for compute 3.2 cards? All I was able to find want 3.5 minimum (((

so far no, and again most of the improvement are post 3.5 so basically even if it was possible it wouldn't be fast
(and the latest code I wrote, would be even more incompatible)

at that point, it is probably better to use sgminer... small worksize playing with -g might help as well

never seen the problem... but its also true i dont mine scrypt ,) i hate this algo and coins using it...

no, i have two rigs with same cards, both crashes if i try use more than 1 card

cudaminer work fine

I see, thanks, so for my laptop with gt730m quark at 1mhs is a only way )))

p.s. Interesting that for lyra pallas'es sgminer gives better results on ot (Kepler) then on ccminer 1.6.5 by tpruvot but with HW errores )))

well if you really want to kill it...

I'm trying more then 1.5 years to do it )) but it still alive ))) pushing hardware to its limit is my illness )))

Do you have device command in your bat file?  This is for 4 cards       -d 0,1,2,3

Do you have device command in your bat file?  This is for 4 cards       -d 0,1,2,3

i`m try with -d 0,1 and withot one, result is same - working only with one card

algo scrypt-jane factor 16

For scrypt jane there are lots of flags that are different for different cards. Here are the configs for

970: --algo=scrypt-jane:16 -L 8 -i 1 -l t32x4 -C 1 -b 65536
750ti: --algo=scrypt-jane:16 -H 2 -L 8 -i 0 -l t64x1 -b 4096 -m 1

I just use different .bat for different cards. If you have enough RAM, its not a problem. Its about 80-100 MB per .bat

I hope this helps.

i`m speek about tpruvot ccminer - it not use additional flags except type of kernel and gap

cudaminer work fine with 5 cards

oh i never got around to that one. How do you optimize the hashrate without all these flags? Is there any improvement in hashrate with that miner because cudaminer hasn't been updated for a while.

I have also added scrypt-n in my fork. I have replaced the keccak implementation, so it should run a littlebit faster.

without the launchconfig it will probobily not work

970: --algo=scrypt-jane:16 -L 8 -i 1 -l t32x4 -C 1 -b 65536
750ti: --algo=scrypt-jane:16 -H 2 -L 8 -i 0 -l t64x1 -b 4096 -m 1

Will those flags work with ccminer for scrypt-jane NF16? or do i just put in the launch config?

Haven't tested, but from the commandline just start the miner like this: (gtx 970) (nfactor 16)

ccminer -a scrypt-jane:16 -L 8 -i 1 -l t32x4 -C 1 -b 65536 -u xxx -p xxx -o stratum(pool adress)

Apologies in advance for dropping the advert:

I'm looking to find 2 people, 3 tops, interested in buying a private ccminer for Axiom.
PM me here or IRC if interested, armed with 0.5 BTC to not waste my time (or yours).

A trusted escrow is absolutely fine if the buyer has not already established prior business trust with me.

As far as I know, this coin is (was) only CPU mined until now, and it has a very hot market on Bitty.
