MVis-tokenminer

This is a fork of my MVis-ethminer program, which was a fork of Genoil's ethminer. CPU & AMD GPU mining are supported. Pool mining and solo mining are both supported.

• This miner should work with any GPU that supports OpenCL, ie. pretty much all AMDs and some NVidia. Performance is generally not very good with nVidia GPUs.
• Windows binaries can be downloaded from the Releases page, or you can build from source (see below).
• For Linux, the only option at present is to build from source. See the instructions below.
• This miner supports both pool mining and solo mining. If you want to mine solo, you either need to run your own node, or use a public one (ie. Infura).
• When in pool mining mode, a 1.0% dev fee is in effect. Every 4 hours it switches to 'dev fee mining' for a short period of time, based on the percent.

Installation

YouTube Tutorial : https://www.youtube.com/watch?v=W-gLERwzKno

• Unzip the download package anywhere you like.
• Double-click on the file list-devices.bat. Examine the screen output and verify your GPU's are recognized. Pay special attention to the PlatformID. If it is anything other than 0, you will need to edit the start-mining.bat file and change the --opencl-platform <n> argument.
• Open up tokenminer.ini using any text editor and set the following configuration items, depending on whether you are solo mining or mining on a pool:

Pool Mining

• For Pool Mining, you need to specify your mining pool URL and your ETH address.

[Node]
Host=http://your_mining_pool.com:8080
Stratum=false

[0xBitcoin]
MinerAcct=0x1234512345123451234512345123451234512345

• All other settings in the [0xBitcoin] section can be left as is.
• You can also specify the pool mining address on the command line (-N). See below for all command line options.
• If your mining pool supports the stratum protocol, set Stratum=true in the Node section, and change the port number to whatever the pool uses.
• Start mining by double-clicking on start-mining.bat.

Solo Mining

• Specify an ETH account and associated private key in the INI file.
• You need to have access to an Ethereum node: either one you are running locally, or a publicly available node (ie. Infura). You can specify the address and port of your node in the .ini file, or on the command line.
• Start mining with tokenminer.exe -S -G. This assumes you've specified the node address in the .INI file.

General

• You can leave the .INI file in the executable folder, or you can move it to C:\Users\[USER]\AppData\Local\tokenminer on Windows, or $HOME/.config/tokenminer on Linux. If that folder path does not exist, you will need to create it manually. If for some reason that file exists at both locations, the one in the executable folder will take precedence.
• WINDOWS ONLY: download and install both the VC 2013 Redistributable and the VC 2015 Redistributable
• COOLING: Please note that MVis-tokenminer does not have any features to set fan speeds or regulate cooling, other than shutting down if things get too hot. Usually the AMD drivers do a pretty good job in that regard, but sometimes they don't. It is your responsibility to monitor your fan speeds and GPU temperatures. If the AMD drivers aren't setting fan speeds high enough, you may need to use a 3rd party product, like Speedfan or Afterburner.

Configuration Details

MVis-tokenminer is partially configured via command line parameters, and partially by settings in tokenminer.ini. Run tokenminer --help to see which settings are available on the command line. Have a look inside the .ini file to see what settings can be configured there. (It is fairly well commented). Some settings can only be set on the command line (legacy ones mostly), some settings can only be set in the .ini file (newer ones mostly), and some can be set in both. For the last group, command line settings take precedence over the .ini file settings.

Command Line Options

Node configuration:
    -N, --node <host:rpc_port>  Host address and RPC port of your node/mining pool. (default: 127.0.0.1:8545)
    -N2, --node2 <host:rpc_port>  Failover node/mining pool (default: disabled)
    -I, --polling-interval <n>  Check for new work every <n> milliseconds (default: 2000). 
    -R, --farm-retries <n> Number of retries until switch to failover (default: 4)

 Benchmarking mode:
    -M,--benchmark  Benchmark for mining and exit
    --benchmark-warmup <seconds>  Set the duration of warmup for the benchmark tests (default: 8).
    --benchmark-trial <seconds>  Set the duration for each trial for the benchmark tests (default: 3).
    --benchmark-trials <n>  Set the number of benchmark tests (default: 5).

 Mining configuration:
    -P  Pool mining
    -S  Solo mining
    -C,--cpu  CPU mining
    -G,--opencl  When mining use the GPU via OpenCL.
    --cl-local-work <n> Set the OpenCL local work size. Default is 128
    --cl-work-multiplier <n> This value multiplied by the cl-local-work value equals the number of hashes computed per kernel 
       run (ie. global work size). (Default: 8192)
    --opencl-platform <n>  When mining using -G/--opencl use OpenCL platform n (default: 0).
    --opencl-device <n>  When mining using -G/--opencl use OpenCL device n (default: 0).
    --opencl-devices <0 1 ..n> Select which OpenCL devices to mine on. Default is to use all
    -t, --mining-threads <n> Limit number of CPU miners to n (default: use everything available on selected platform)
    --allow-opencl-cpu  Allows CPU to be considered as an OpenCL device if the OpenCL platform supports it.
    --list-devices List the detected OpenCL/CUDA devices and exit. Should be combined with -G or -U flag
    --cl-extragpu-mem <n> Set the memory (in MB) you believe your GPU requires for stuff other than mining. default: 0

 Miscellaneous Options:
    --config <FileSpec>  - Full path to an INI file containing program options. Default location is 1) the executable folder, or 
                           if not there, then in 2) %LocalAppData%/tokenminer/tokenminer.ini (Windows) or 
                           $HOME/.config/tokenminer/tokenminer.ini (Linux).  If this option is specified,  it must appear 
                           before all others.

 General Options:
    -V,--version  Show the version and exit.
    -h,--help  Show this help message and exit.

Building on Windows

• download and install Visual Studio 2015. This project requires the v120 toolset. See this Stack Overflow question to make sure the v120 toolset gets installed onto your system.
• download and install CMake
• download or clone this repository into a folder. Let's call it <mvis_folder>.
• run getstuff.bat in the extdep folder.
• open a command prompt in <mvis_folder> and enter the following commands. (Note: the string "Visual Studio 12 2013 Win64" is not a typo.)

mkdir build 
cd build
cmake -G "Visual Studio 12 2013 Win64" ..

Visual Studio

• Use Visual Studio to open mvis-tokenminer.sln located in the build directory.
• Visual Studio may offer to convert the project files from 2013 format to 2015 format. Do not accept this!! Click Cancel to keep the projects using the VS2013 toolset.
• Set tokenminer as the startup project by right-clicking on it in the project pane.
• Build. Run

Building on Ubuntu

Ubuntu 16.04

This has only been verified to work with Ubuntu 16.04. OpenCL only (for AMD cards)

sudo apt-get update
sudo apt-get -y install software-properties-common
sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install git cmake libcryptopp-dev libleveldb-dev libjsoncpp-dev libjsonrpccpp-dev libboost-all-dev libgmp-dev libreadline-dev libcurl4-gnutls-dev ocl-icd-libopencl1 opencl-headers mesa-common-dev libmicrohttpd-dev build-essential -y
git clone https://github.com/mining-visualizer/MVis-tokenminer.git <mvis_folder>
cd <mvis_folder>
mkdir build
cd build
cmake -DBUNDLE=miner ..
make

You can then find the executable in the build/ethminer subfolder

Ubuntu 18.04

Unverified: A user has reported that you can build this under Ubuntu 18.04 by simply changing libcryptopp-dev to libcrypto++-dev in the apt-get install command above.
