XMR-Stak-CPU - Monero mining software

XMR-Stak is a universal Stratum pool miner. This is the CPU-mining version, but I'm planning to release Nvidia and AMD GPU versions too.

Usage on Windows

Edit the config.txt file to enter your pool login and password.
Double click the exe file.

XMR-Stak should compile on any C++11 compliant compiler. Windows compiler is assumed to be MSVC 2015 CE. MSVC build environment is not vendored.

Usage on Linux

    cmake .
    make

GCC version 5.1 or higher is required for full C++11 support. CMake release compile scripts, as well as CodeBlocks build environment for debug builds is included.

To do a static build for a system without gcc 5.1+

    cmake -DCMAKE_BUILD_TYPE=STATIC
    make

Note - cmake caches variables, so if you want to do a dynamic build later you need to specify '-DCMAKE_BUILD_TYPE=RELEASE'

CPU mining performance

Performance is nearly identical to the closed source paid miners. Here are some numbers:

I7-2600K - 266 H/s
I7-6700 - 276 H/s (with a separate GPU miner)
Dual X5650 - 466 H/s (depends on NUMA)
Dual E5640 - 365 H/s (same as above)

Default dev donation

By default the miner will donate 1% of the hashpower (1 minute in 100 minutes) to my pool. If you want to change that, edit donate-level.h before you build the binaries.

If you want to donate directly to support further development, here is my wallet
