HPC has been using Same Instruction, Multiple Data (SIMD) paradigms to increase the performance of machines, libraries, and codes since the early days of the Cray Vector processor. This talk provides a historical overview of x86 and x86_64 SIMD instruction sets from the 90's to modern, currently unreleased processors. It seeks to introduce the new AVX10 specification, specifically its impact within High Performance Computing.
Focusing on HPC, this talk is targeted towards two primary demographics: HPC packaging/system supporters/administrators and HPC Compiler/Math Library optimization Developers.
The goal of this talk is demystifying x86_64 Advanced Vector eXtensions in all its forms, from the original HPC focused AVX1, the general workload focused AVX2, the 7 different non-overlapping levels of AVX-512, and a return to normality with AVX10 in its 2.5 forms. HPC specifically will benefit from AVX10 not by having new instructions, but rather by resetting the common baseline that developers, administrators and users can target. Regardless of their cluster, a simple check of two flags for code size, and the feature set level is known. No more custom lookup tables for various non-overlapping implementations.
