Made a cuda port of actual Silentarmy 5

speeds sucks. 92 s/s on overclocked 1070(opencl version give near 100)

Tested only on linux.

If anyone want

https://github.com/krnlx/nheqminer

too bad it dumped :

Code:

~/aaa/nheqminer/Linux_cmake/nheqminer_cuda_sa$ ./nheqminer_cuda_sa -l eu1-zcash.flypool.org:3333 -u t1M74VKHZDJnHwmwWiHUiMWkBkzgQW4VGeg -cv 0 -cs -cd 0 -t 0

But it's not the fault of your port - it's the same with the plain nheqminer 0.4b and the cuda_tromp solver. maybe again bad luck with the old computing (30) version.

Regards

Try adding some flags in CMakeLists.txt for older compute capabilities 3.5 or 5.0. For 750Ti i solved it adding 5.0 flags:

set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS};; -gencode arch=compute_50,code=sm_50;-gencode arch=compute_52,code=sm_52; -gencode arch=compute_61,code=sm_61 )

afaik the compute version is detected and used - definitions to use 3.0 are in the CMakeList ..

It still dumps - must be something different ..

regards

In krnlx repository the cmakelists.txt file has been modified. For 750ti cards i had to modify it.
