CPUMiner-Multi

This is a multi-threaded CPU miner, fork of LucasJones' cpuminer-multi.

Table of contents

Algorithms

Currently supported

  • cryptonight (Bytecoin [BCN], Monero)

Dependencies

Download

Build

Basic *nix build instructions:

  • ./autogen.sh # only needed if building from git repo
  • Optimal GCC flags are built in - you only need to use -march=native if you want it
  • CFLAGS="-march=native" ./configure
    • # Use -march=native if building for a single machine
  • make

Architecture-specific notes:

  • CryptoNight works only on x86 and x86-64.
  • If you don't have AES-NI, it's slower. A lot slower, around 1/3rd the speed. This implementation is deprecated and will not be improved.

Usage instructions

Run "minerd --help" to see options.

Connecting through a proxy

Use the --proxy option.

To use a SOCKS proxy, add a socks4:// or socks5:// prefix to the proxy host
Protocols socks4a and socks5h, allowing remote name resolving, are also available since libcurl 7.18.0.

If no protocol is specified, the proxy is assumed to be a HTTP proxy.
When the --proxy option is not used, the program honors the http_proxy and all_proxy environment variables.

Credits

This faster CPUMiner-multi was forked from LucasJones', and has been developed by Wolf. Special thanks to Intel for helping me with the usage of the AESKEYGENASSIST instruction, which I used to replace the calls to the slow, unoptimized oaes_lib. Special thanks also to dga for his code with that loop - since it runs over 500,000 times per hash, it's extremely important.
