Intel Demonstrates Up to 48% Improvement for AVX-512 Optimized PostgreSQL
- aurareturn 2y agoDo server applications ever optimize for ARM-equivalent of AVX512? Given that AWS heavily uses Graviton, I assume so? But I never hear of them - only AVX512 optimizations.
- EdSchouten 2y agoARM64’s equivalent (NEON) only has 128 bit registers, so the gains of using SIMD are not as massive as on x86-64. Edit: turns out there’s nowadays something called SVE that provides wider registers: https://developer.arm.com/Architectures/Scalable%20Vector%20Extensions https://developer.arm.com/Architectures/Scalable%20Vector%20...

- SvenL 2y agoI once heard that running excessively AVX workload creates a lot of heat on the cpu die which causes the cpu to throttle, which infect also reduces speed. I also heard that some cloud provider disable AVX for VM since one VM can influence the performance of the host due to the speed throttle. Is this still the case?
- SvenL 2y agoIt seems this is fixed: https://x.com/lemire/status/1835703765191573740 https://x.com/lemire/status/1835703765191573740
