> I think when I tried my hand at a similar approach with panama I ran into similar (neutral) results on graviton2 and really the only thing that helped there was prefetching into cpu cache. Totally believe the results are better elsewhere, it's just been a bit of a struggle to stand up the tests on other machines given the resources I have at hand. When benchmarking ARM, I really recommend to only worry about Graviton3 (ARM SVE). IMO we should stop investing any time into 128-bit Neon (Macs, Graviton2, etc). I realize macs are convenient, but the sooner we drop vectorization support for this legacy instruction set, the better. It is not well supported by openjdk, so i see no path to success there. -- This is an automated message from the Apache Git Service.
