cpuminer-opt is a fork of cpuminer-multi by TPruvot with optimizations imported from other miners developped by lucas Jones, djm34, Wolf0, pooler, Jeff garzik, ig0tik3d, elmad, palmd, and Optiminer, with additional optimizations by Jay D Dee.

All of the code is believed to be open and free. If anyone has a claim to any of it post your case in the cpuminer-opt Bitcoin Talk forum or by email.

Requirements

1. A x86_64 architecture CPU with a minimum of SSE2 support. This includes Intel Core2 and newer and AMD equivalents. In order to take advantage of AES_NI optimizations a CPU with AES_NI is required. This includes Intel Westbridge and newer and AMD equivalents. Further optimizations are available on some algoritms for CPUs with AVX and AVX2, Sandybridge and Haswell respectively.

Older CPUs are supported by cpuminer-multi by TPruvot but at reduced performance.

2. 64 bit Linux OS. Ubuntu and Fedora based distributions, including Mint and Centos are known to work and have all dependencies in their repositories. Others may work but may require more effort. 64 bit Windows OS is supported with mingw_w64 and msys or pre-built binaries.

3. Stratum pool, cpuminer-opt only supports stratum minning. Some algos may work wallet mining but there are no guarantees.

Errata

cpuminer-opt does not work mining Decred algo at Nicehash and produces only "invalid extranonce2 size" rejects.

Benchmark testing does not work for x11evo.
