Beam Equihash 150/5 CUDA Miner

Copyright 2018 The Beam Team

Usage

One Liner Examples

Linux: ./beam-cuda-miner --server <hostName>:<portNumer> --key <apiKey> --devices <deviceList>
Windows: beam-cuda-miner --server <hostName>:<portNumer> --key <apiKey> --devices <deviceList>

Parameters

--server

Passes the address and port of the node the miner will mine on to the miner. The server address can be an IP or any other valid server address.- For example when the node is running on the same computer and listens on port 17000 then use --server localhost:17000

--key

Pass a valid API key from "stratum.api.keys" to the miner. Required to authenticate the miner at the node

--list-devices (Optional)

List all devices that are present in the system and their order start the miner. Then all devices will be listed, but none selected for mining.

--devices (Optional)

Selects the devices to mine on. If not specified the miner will run on all devices found on the system. For example to mine on GPUs 0,1 and 3 but not number 2 use --devices 0,1,3 Best practice is to specify pciBusID:pciDeviceID to select a device: --devices 1:0,2:0 The miner closes when no devices were selected for mining or all selected miner fail in the compatibility check.

How to build

Windows

1. Install Visual Studio >= 2017 with CMake support.
2. Download and install OpenSSL prebuilt binaries https://slproweb.com/products/Win32OpenSSL.html (Win64 OpenSSL v1.1.0h for example).
3. Download and install CUDA Toolkit https://developer.nvidia.com/cuda-downloads
4. Open project folder in Visual Studio, select your target (x64-Release for example, if you downloaded 64bit OpenSSL) and select CMake -> Build All.
5. Go to CMake -> Cache -> Open Cache Folder -> beam-cuda-miner (you'll find beam-cuda-miner.exe).

Linux (Ubuntu 14.04)

1. Install gcc7 ssl packages.

   sudo add-apt-repository ppa:ubuntu-toolchain-r/test
   sudo apt update
   sudo apt install g++-7 libssl-dev -y

2. Set it up so the symbolic links gcc, g++ point to the newer version:

   sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 60 \
                          --slave /usr/bin/g++ g++ /usr/bin/g++-7 
   sudo update-alternatives --config gcc
   gcc --version
   g++ --version

3. Download and install CUDA Toolkit https://developer.nvidia.com/cuda-downloads
4. Install CMake

   sudo apt install cmake

5. Go to beam-opencl-miner project folder, make directory build, change dir to build and call cmake -DCMAKE_BUILD_TYPE=Release .. && make.

   mkdir build
   cd build
   cmake -DCMAKE_BUILD_TYPE=Release .. 
   make

6. You'll find beam-cuda-miner binary in build/equihash folder.
