This is the home of cpuminer-opt, the optimized x86_64 CPU miner.

Supporting over 90 agorithms with many optimized for x86_64 CPUs with the latest technologies:

Intel Haswell: AVX2
AMD Zen1: AVX2 and SHA
AMD Zen3, Intel Alderlake*: AVX2, SHA and VAES
Intel Skylake X: AVX512
AMD Zen4, Intel Rocketlake: AVX512, SHA, and VAES

Older 64 bit CPUs with SSE2 are also supported, see below for requirements.
*Alderlake and subsequent Intel desktop architectures are hybrid architecture with AVX512 disabled.
Intel has no current consumer desktop CPUs supporting AVX512.

Downloads

Source code and Windows binaries are avaiable for download. Windows binaries support CPUs up to 64 threads,
higher requires compiling from source with CPU group support, see Wiki for details.
Download only from the official JayDDee git repository.
There may be malware masquerading as cpuminer-opt, stay alert.
I no longer post links in new mesages and I don't post direct links to files. Any such links should be treated
with suspicion. The only valid download link is below and directs to a landing page that can be examined
for legitimacy before any files are downloaded.

Source code
https://github.com/JayDDee/cpuminer-opt

New in v3.22.3
Data interleaving and byte swap optimizations with AVX2, AVX512 & AVX512VBMI.
Faster Luffa with AVX2 & AVX512.
Other small optimizations.
Some code cleanup.

New in v3.22.2

Added sha512256d & sha256dt algos.
Fixed intermittant invalid shares lyra2v2 AVX512.
Removed application limits on the number of CPUs and threads, HW and OS limits still apply.
Added a log warning if more threads are defined than active CPUs in affinity mask.
Improved merkle tree memory management for stratum.
Added transaction count to New Work log.
Other small improvements.

New in v3.22.1

#393 fixed segfault in GBT, regression from v3.22.0.
More efficient 32 bit data interleaving.

New in v3.22.0

Stratum: faster netdiff calculation.
Merged a few updates from Pooler/cpuminer:
   Use CURLOPT_POSTFIELDS in json_rpc_call,
   Use CURLINFO_ACTIVESOCKET when supported,
   JSONRPC speedup,
   Speed up hex2bin function.
Small log improvements, notably more frequent hash rate reports.
Removed decred algo.

Full change log: https://github.com/JayDDee/cpuminer-opt/blob/master/RELEASE_NOTES

Requirements:

1. A x86_64 architecture CPU with a minimum of SSE2 support. This includes Intel Core2 and newer and AMD equivalents.
AES optimizations require a CPU with AES_NI including Intel Westmere and newer and AMD equivalents.
Further optimizations are available on some algorithms for CPUs with AVX (Sandybridge), AVX2 (Haswell, Zen1),
AVX512 (Rocketlake, Skylake-X, Zen4), SHA (Zen1, Rocketlake), and VAES (Zen3, Rocketlake).

32 bit Intel and AMD CPUs are not supported. Other architectures such as ARM, Raspberry Pi, RISC-V, etc, are not supported.
Mobile devices like lapotop computers are not recommended because they aren't designed for continuous full load.

2. 64 bit Linux OS. Debian and Fedora based distributions including Ubuntu, Mint, RHEL and clones are known to work and have all dependencies in their
repositories. Others may work but may require more effort.

Windows 7 or newer 64 bits is supported using the pre-compiled binaries package or may be compiled from source using MinGW.

FreeBSD is not actively tested but should work, YMMV.
Apple and Android operating systems are not supported.

Older CPUs, other architectures and operating systems may be supported by TPruvot's cpuminer-multi.

Security warning

Cryptocurrency miners often flagged as malware by antivirus programs. This is usually a false positive, they are flagged simply
because of what they are. However, some malware has been spread using the cover that miners are known to be subject to
false positives. Always be on alert. The source code of cpuminer-opt is open for anyone to inspect. If you don't trust the software
don't download it.

Some cryptographic code has been taken from trusted sources but has been modified for speed at the expense of accepted
security practices. This code should not be imported into applications where secure cryptography is required.

Errata:

Old algorithms that are rarely used or are too difficult to mine with a CPU will not get the latest optimizations.
Cryptonight and variants are no longer supported, use other miners.
Hodl requires a CPU with AES.

Donations

cpuminer-opt has no fees of any kind but donations are accepted.
