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.
Miner programs are often flagged as malware by antivirus programs. This is a false positive, they are flagged simply because they are cryptocurrency miners. The source code is open for anyone to inspect. If you don't trust the software, don't use it.

This note is to confirm that bitcointalk users JayDDee and joblo are the same person.
I created a new BCT user JayDDee to match my github user id. The old thread has been locked but still contains useful information for reading.
See file RELEASE_NOTES for change log and INSTALL_LINUX or INSTALL_WINDOWS for compile instructions.
32 bit CPUs are not supported. Other CPU architectures such as ARM, Raspberry Pi, RISC-V, Xeon Phi, etc, are not supported.
Mobile CPUs like laptop computers are not recommended because they aren't designed for extreme heat of operating at full load for extended periods of time.
Older CPUs and ARM architecture may be supported by cpuminer-multi by TPruvot.
Windows 7 or newer is supported with mingw_w64 and msys or using the pre-built binaries. WindowsXP 64 bit is YMMV.
FreeBSD is not actively tested but should work, YMMV. MacOS, OSx and Android are not supported.

zr5 ZiftrMany variations of scrypt based algos can be mine by specifying their parameters:
scryptn2: --algo scrypt --param-n 1048576
cpupower: --algo yespower --param-key "CPUpower: The number of CPU working or available for proof-of-work mining"
power2b: --algo yespower-b2b --param-n 2048 --param-r 32 --param-key "Now I am become Death, the destroyer of worlds"

yespowerltncg: --algo yespower --param-n 2048 --param-r 32 --param-key "LTNCGYES"
Old algorithms that are no longer used frequently will not have the latest optimizations.
Cryptonight and variants are no longer supported, use another miner.
Neoscrypt crashes on Windows, use legacy version.
AMD CPUs older than Piledriver, including Athlon x2 and Phenom II x4, are not supported by cpuminer-opt due to an incompatible implementation of SSE2 on these CPUs. Some algos may crash the miner with an invalid instruction. Users are recommended to use an unoptimized miner such as cpuminer-multi.
cpuminer-opt does not work mining Decred algo at Nicehash and produces only "invalid extranonce2 size" rejects.
Benchmark testing does not work for x11evo.
Users are encouraged to post their bug reports using git issues or on the Bitcoin Talk forum or opening an issue in git:

All problem reports must be accompanied by a proper problem definition. This should include how the problem occurred, the command line and output from the miner showing the startup messages and any errors. A history is also useful, ie did it work before.
cpuminer-opt has no fees of any kind but donations are accepted.

Happy mining!
