Nothing stops someone from copying and submitting other implementation's algorithm. There are multiple implementations of each benchmark for every language: • https://benchmarksgame-team.pages.debian.net/benchmarksgame/program/revcomp-rust-1.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/... • https://benchmarksgame-team.pages.debian.net/benchmarksgame/program/revcomp-rust-2.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/... • https://benchmarksgame-team.pages.debian.net/benchmarksgame/program/revcomp-rust-3.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/... It's possible that someone has already submitted both algorithms for both languages, and different approaches won for language-specific reasons.

These are all the C versions I can find: https://benchmarksgame-team.pages.debian.net/benchmarksgame/program/revcomp-gcc-2.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/... https://benchmarksgame-team.pages.debian.net/benchmarksgame/program/revcomp-gcc-4.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/... https://benchmarksgame-team.pages.debian.net/benchmarksgame/program/revcomp-gcc-5.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/... https://benchmarksgame-team.pages.debian.net/benchmarksgame/program/revcomp-gcc-6.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/... None of them have SSE intrinsics or are quite as long as the Rust version. I find it doubtful that SSE intrinsics wouldn't help the C version, if they are indeed helping the Rust version. This seems fairly easy to check as the Rust version has a non-SSE fallback code path - I'd do it myself but am not able to at the moment.

  When someone on proggit writes — "Yeah it's really hard to submit code. Not only do you have to sign up for their site but they don't accept Gmail addresses." — they may just be repeating something they read on proggit.

It's only 6 weeks since that Rust revcomp #1 program was contributed — November 23, 2020.
