That's before the performance bugfix we talked about, right? (We re-initialized the RNG on every sort.)
Vqsort performance on M1 is indeed about half that of AVX-512. The NEON instruction set is missing some important operations for Quicksort, including Compress and popcount of vector masks.
- Voultapher 3y agoYes, like everything before the addendum the results are for the the same tested vqsort version without the bug-fix, as I motivate in the section "Author's conclusion and opinion" at the end. I suspect thought that even the new version will not outperform crumsort or ipnsort on this machine.
