benchmark SIMD with highway

Open laoshaw opened this issue 2 years ago • 1 comments

SIMD benchmark is hard to find if there is any, as each arch needs some hand crafting for the best result.

can we make a highway-based SIMD benchmark that runs on AVX|SVE|RVV to compare their performance apple to apple?

Hi @laoshaw , thanks for reaching out. This is a very interesting topic. We do have such a benchmark for vectorized quicksort, see hwy/contrib/sort/bench_*. We've tested this on x86, NEON and SVE, with interesting results (https://onlinelibrary.wiley.com/doi/abs/10.1002/spe.3142).

We'd welcome pull requests for benchmarks of other algorithms and I'm happy to help or advise on that if you would like to develop one.
