Please note miners are often marked as malware by antivirus programs. This is not so, they are marked simply because they are cryptocurrency miners. If you do not trust the software, do not use it!
cpuminer-opt is a branch of cpuminer-multi from TPruvot with optimizations imported from other miners developed by Lucas Jones, djm34, Wolf0, pooler, Jeff Garzik, ig0tik3d, elmad, palmd and Optiminer, with additional optimizations by JD Dee.
All code is considered open and free. If anyone has a complaint about any of them, post your case on 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 labeled simply because they are cryptocurrency miners. The source code is open to all. If you do not trust the software, do not use it.
This note confirms that bitcointalk users JayDDee and joblo are the same person.
I created a new BCT JayDDee user according to my github user id. The old thread was blocked, but still contains useful information to read.
See the RELEASE_NOTES file for the change log and INSTALL_LINUX or INSTALL_WINDOWS for compilation instructions.
X86_64 architecture processor with minimal SSE2 support. This includes Intel Core2 and newer and AMD equivalents. Further optimization is available for some algorithms for processors with AES, AVX, AVX2, SHA, AVX512 and VAES.
64-bit Linux or Windows. It is known that distributions based on Ubuntu and Fedora, including Mint and Centos, work and have all the dependencies in their repositories. Others may work, but may require more effort. Older versions, such as Centos 6, do not work due to missing features. 64-bit Windows is supported with mingw_w64 and msys or pre-compiled binaries.
A stratum pool supporting strata + tcp: // or strata + ssl: // protocols or RPC getwork using http: // or https: //. GBT is YMMV.
Older processors are supported by cpuminer-multi TPruvot, but with reduced performance.
Older algorithms that are no longer used often will not have the latest optimizations.
Cryptonight and its variants are no longer supported, use another miner.
Neoscrypt crashes on Windows, use an outdated version.
AMD processors older than Piledriver, including Athlon x2 and Phenom II x4, are not supported by cpuminer-opt due to the incompatible implementation of SSE2 on these processors. Some algorithms may crash the miner with the wrong instruction. Users are advised to use an unoptimized miner such as cpuminer-multi.
cpuminer-opt Decred algo mining does not work in Nicehash and only produces extranonce2 invalid size deviations.
