This plot shows the time it takes to integrate the Solar System for 5 billion years. In 1950 it would have taken over a million years. Today it takes 1 day. The bottom right point is for our WHFast512 integrator which uses #AVX512 instructions: https://astro.theoj.org/article/84547-whfast512-a-symplectic-n-body-integrator-for-planetary-systems-optimized-with-avx512-instructions

Hi friends! Very excited to announce that I'll be giving an @easy_build Tech Talk on the 13th of October on #AVX10!
The Talk is titled "AVX10 for HPC:
A reasonable solution to the 7 levels of AVX-512 folly"
Registration is free, all #x86, #AVX, #AVX512, #SIMD, and #HPC experience levels welcome!
