Linux

Work in progress.

Working solvers CPU_TROMP, CPU_XENONCAT, CUDA_TROMP

Work in progress (OCL_XMP)

Linux (Ubuntu 14.04 / 16.04) Build CPU_XENONCAT:

• Open terminal and run the following commands:
  • sudo apt-get install cmake build-essential libboost-all-dev
  • git clone -b Linux https://github.com/nicehash/nheqminer.git
  • cd nheqminer/cpu_xenoncat/Linux/asm/
  • sh assemble.sh
  • cd ../../../Linux_cmake/nheqminer_cpu
  • cmake .
  • make -j $(nproc)

Linux (Ubuntu 14.04 / 16.04) Build CUDA_TROMP:

• Open terminal and run the following commands:
  • Ubuntu 14.04:
    • wget http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1404/x86_64/cuda-repo-ubuntu1404_8.0.44-1_amd64.deb
    • sudo dpkg -i cuda-repo-ubuntu1404_8.0.44-1_amd64.deb
  • Ubuntu 16.04:
    • wget http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/cuda-repo-ubuntu1604_8.0.44-1_amd64.deb
    • sudo dpkg -i cuda-repo-ubuntu1604_8.0.44-1_amd64.deb
  • sudo apt-get update
  • sudo apt-get install cuda
  • sudo apt-get install cuda-toolkit-8-0
  • sudo apt-get install cmake build-essential libboost-all-dev
  • git clone -b Linux https://github.com/nicehash/nheqminer.git
  • cd nheqminer/Linux_cmake/nheqminer_cuda_tromp && cmake . && make -j $(nproc)
  • or specify your compute version for example 50 like so cd nheqminer/Linux_cmake/nheqminer_cuda_tromp && cmake COMPUTE=50 . && make

Run instructions:

Parameters: -h Print this help and quit -l [location] Stratum server:port -u [username] Username (bitcoinaddress) -a [port] Local API port (default: 0 = do not bind) -d [level] Debug print level (0 = print all, 5 = fatal only, default: 2) -b [hashes] Run in benchmark mode (default: 200 iterations)

CPU settings -t [num_thrds] Number of CPU threads -e [ext] Force CPU ext (0 = SSE2, 1 = AVX, 2 = AVX2)

NVIDIA CUDA settings -ci CUDA info -cd [devices] Enable CUDA mining on spec. devices -cb [blocks] Number of blocks -ct [tpb] Number of threads per block Example: -cd 0 2 -cb 12 16 -ct 64 128

If run without parameters, miner will start mining with 75% of available logical CPU cores. Use parameter -h to learn about available parameters:

Example to run benchmark on your CPU:

    nheqminer -b

Example to mine on your CPU with your Zcash address and worker1 on Flypool USA server:

    nheqminer -l us1-zcash.flypool.org:3333 -u YOUR_Zcash_ADDRESS_HERE.worker1

Example to mine on your CPU with your own Zcash address and worker1 on EU server, using 6 threads:

    nheqminer -l eu1-zcash.flypool.org:3333 -u YOUR_Zcash_ADDRESS_HERE.worker1 -t 6

Note: if you have a 4-core CPU with hyper threading enabled (total 8 threads) it is best to run with only 6 threads (experimental benchmarks shows that best results are achieved with 75% threads utilized)

Example to mine on your CPU as well on your CUDA GPUs with your own Zcash address and worker1 on EU server, using 6 CPU threads and 2 CUDA GPUs:

    nheqminer -l eu1-zcash.flypool.org:3333 -u YOUR_Zcash_ADDRESS_HERE.worker1 -t 6 -cd 0 1
