XMR-Stak-POWER - Monero mining software for POWER8 and later

XMR-Stak-POWER is a universal Stratum pool miner and a fork of XMR-Stak-CPU. There is also an AMD GPU version and an NVIDIA GPU version

HTML and JSON API report configuraton

To configure the reports shown above you need to edit the httpd_port variable. Then enable wifi on your phone and navigate to [miner ip address]:[httpd_port] in your phone browser. If you want to use the data in scripts, you can get the JSON version of the data at url [miner ip address]:[httpd_port]/api.json

Installing IBM compiler

XMR-Stak-POWER will currently only compile with the GCC 6.3.1 compiler included in the IBM AT10.0 developer tools. [IBM Advance Toolchain](https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/W51a7ffcf4dfd_4b40_9d82_446ebc23c550/page/IBM Advance Toolchain for PowerLinux Documentation)

Compile guides

• Linux

CPU mining performance

Here are some numbers:

• Dual POWER8 10C @ 3.5GHz, running 4 threads per core, hugepages enabled - 4150 H/s
• Dual POWER9 12C @ 3.5GHz, running 4 threads per core, hugepages enabled - Being Optimized

Default dev donation

By default the miner will donate 0.88% of the hashpower. If you have POWER hardware available you are probably rich, so please donate to my/our address!

Advanced Compile Options

The build system is CMake, if you are not familiar with CMake you can learn more here.

Short Description

There are two easy ways to set variables for cmake to configure xmr-stak-cpu

• use the ncurses GUI
  • ccmake .
  • edit your options
  • end the GUI by pressing the key c(create) and than g(generate)
• set Options on the command line
  • enable a option: cmake . -DNAME_OF_THE_OPTION=ON
  • disable a option cmake . -DNAME_OF_THE_OPTION=OFF
  • set a value cmake . -DNAME_OF_THE_OPTION=value

After the configuration you need to call make install for slow sequential build or make -j install for faster parallel build and install.

xmr-stak-cpu Compile Options

• CMAKE_INSTALL_PREFIX install miner to the home folder
  • cmake . -DCMAKE_INSTALL_PREFIX=$HOME/xmr-stak-cpu
  • you can find the binary and the config.txt file after make install in $HOME/xmr-stak-cpu/bin
• CMAKE_LINK_STATIC link libgcc and libstdc++ libraries static (default OFF)
  • disable with cmake . -DCMAKE_LINK_STATIC=ON -CMAKE_BUILD_TYPE set the build type
  • valid options: Release or Debug
  • you should always keep Release for your productive miners
• MICROHTTPD_ENABLE allow to disable/enable the dependency microhttpd
  • by default enabled
  • there is no http interface available if option is disabled: cmake . -DMICROHTTPD_ENABLE=OFF
• OpenSSL_ENABLE allow to disable/enable the dependency OpenSSL
  • by default enabled
  • it is not possible to connect to a https secured pool if option is disabled: cmake . -DOpenSSL_ENABLE=OFF
• HWLOC_ENABLE allow to disable/enable the dependency hwloc
  • by default enabled
  • the config suggestion is not optimal if option is disabled: cmake . -DHWLOC_ENABLE=OFF
