Build instructions:

Dependencies:

Boost 1.62+

Windows:

Windows builds made by us are available here: https://github.com/nicehash/nheqminer/releases

Download and install:

CUDA SDK (if not needed remove USE_CUDA_TROMP and USE_CUDA_DJEZO from nheqminer Preprocessor definitions under Properties > C/C++ > Preprocessor)
Visual Studio 2013 Community: https://www.visualstudio.com/en-us/news/releasenotes/vs2013-community-vs
Visual Studio Update 5 installed
64 bit version only

Open nheqminer.sln under nheqminer/nheqminer.sln and build. You will have to build ReleaseSSE2 cpu_tromp project first, then Release7.5 cuda_tromp project, then select Release and build all.

Enabled solvers:

USE_CPU_TROMP
USE_CPU_XENONCAT
USE_CUDA_TROMP
USE_CUDA_DJEZO

If you don't wan't to build with all solvlers you can go to nheqminer Properties > C/C++ > Preprocessor > Preprocessor Definitions and remove the solver you don't need.

Linux

Work in progress. Working solvers CPU_TROMP, CPU_XENONCAT, CUDA_TROMP, CUDA_DJEZO

General instructions:

Install CUDA SDK v8 (make sure you have cuda libraries in LD_LIBRARY_PATH and cuda toolkit bins in PATH)
- example on Ubuntu:
- LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda-8.0/lib64:/usr/local/cuda-8.0/lib64/stubs"
- PATH="$PATH:/usr/local/cuda-8.0/"
- PATH="$PATH:/usr/local/cuda-8.0/bin"
Use Boost 1.62+ (if it is not available from the repos you will have to download and build it yourself)
CMake v3.5 (if it is not available from the repos you will have to download and build it yourself)
Currently support only static building (CPU_XENONCAT, CUDA_DJEZO are enabled by default, check CMakeLists.txt in nheqminer root folder)
If not on Ubuntu make sure you have fasm installed and accessible in PATH
After that open the terminal and run the following commands:
- git clone https://github.com/nicehash/nheqminer.git
- Generating asm object file:
  - On Ubuntu:
  - cd nheqminer/cpu_xenoncat/asm_linux/
  - sh assemble.sh
  - bundeled fasm not compatible:
  - delete/replace (inside nheqminer/cpu_xenoncat/asm_linux/ directory) with fasm binary compatible with your distro
  - cd nheqminer/cpu_xenoncat/asm_linux/
  - sh assemble.sh
- cd ../../../
- mkdir build && cd build
- cmake ../nheqminer
- make -j $(nproc)

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 own BTC address and worker1 on NiceHash USA server:

    nheqminer -l equihash.usa.nicehash.com:3357 -u YOUR_BTC_ADDRESS_HERE.worker1

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

    nheqminer -l equihash.eu.nicehash.com:3357 -u YOUR_BTC_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 BTC address and worker1 on EU server, using 6 CPU threads and 2 CUDA GPUs:

    nheqminer -l equihash.eu.nicehash.com:3357 -u YOUR_BTC_ADDRESS_HERE.worker1 -t 6 -cd 0 1
