CPUMiner-opt

This is a multi-threaded CPU miner, fork of pooler's cpuminer (see AUTHORS for list of contributors).

This specific fork has AES optimizations for many algorithms, they are automatically used if your compiler, your CPU and the algorithm in question support it.

How to build

git clone https://github.com/hmage/cpuminer-opt
cd cpuminer-opt
sudo apt-get install libssl-dev libcurl4-openssl-dev libjansson-dev
./build.sh

The resulting binary will be named cpuminer.

Implemented, but untested

• ? blake2s
• ? hefty1 (Heavycoin)
• ? keccak (Maxcoin, HelixCoin, CryptoMeth, Galleon, 365coin, Slothcoin, BitcointalkCoin)
• ? luffa (Joincoin, Doomcoin)
• ? shavite3 (INKcoin)
• ? sib (SibCoin)

Dependencies

• libcurl http://curl.haxx.se/libcurl/
• jansson http://www.digip.org/jansson/
• openssl https://www.openssl.org/

Easiest way to get them on Debian-based distributions is to run:

sudo apt-get install libssl-dev libjansson-dev libcurl4-nss-dev

Usage instructions

Run cpuminer --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.
