The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

AVX-512 Performance Comparison: AMD Genoa vs. Intel Sapphire Rapids & Ice Lake Review
PAR2 creation (file-based error correction): the core routine here is GF(2^16) matrix multiplication. AVX512 has the GF2P8AFFINEQB instruction, which isn't present on any GPU that I know of, but massively accelerates GF multiplication. Without this instruction, you have to resort to emulating it via bitwise operations or lookup tables, which are much slower. I actually have an OpenCL implementation, but its performance is rather meh compared to CPU

Optimal par2 Switches for Mixed Data . .
Did you tried to use parpar for creating par2 files? Supposed to be much faster. https://github.com/animetosho/ParPar

AMD EPYC 9554 & EPYC 9654 Benchmarks
I've been developing a performance oriented PAR2 tool (used for generating file-based redundancy for error correction), but without access to a lot of hardware, I don't have that much ability to tune it to various microarchitectures. Currently there's no real benchmark setup defined/implemented (though it shouldn't be hard to come up with one), and it certainly isn't tuned for the number of cores on EPYC, but I've never really thought PAR2 benchmarks would interest that many people.

Analysing the Effectiveness of WinRAR's RAR5 Recovery Records
QuickPar is ancient at this stage, however the PAR2 format hasn't changed since, so the concepts are still the same. For a more modern client, I generally recommend MultiPar. I've also written a PAR2 client, ParPar (CLI, or experimental GUI frontend), but it only supports creating PAR2s, not verify/repair.

What is the best method for file integrity preservation?
Also this implementation of par is the fastest I've seen (for creation only thought) https://github.com/animetosho/ParPar

Fastest Parity creator on Linux
For PAR2, I did a benchmark comparison here of every tool, which you can use to make up your mind. par2j (Multipar) and phpar2 are Windows only, but work via Wine. ParPar only supports create, so you'll need to use a different client for verify/repair.

AVX-512 Performance Comparison: AMD Genoa vs. Intel Sapphire Rapids & Ice Lake Review
yEnc encoding/decoding (used in Usenet binary transfers): performance is upwards of 6GB/s on one core of a modern CPU. Even if we assume a GPU has infinite performance, just the transfer to+from over a PCI-e link likely isn't much faster. yEnc also operates on bytes (which GPUs suck at relative to CPUs) and involves a fair bit of conditional data shuffling
What are some alternatives?
When comparing ParPar and rapidyenc you can also consider the following projects:
