We describe the implementation of the symplectic N-body integrator WHFast512 using Single Instruction Multiple Data (SIMD) parallelism and 512-bit Advanced Vector Extensions (AVX512). We are able to speed up integrations of planetary systems by up to 4. 7x compared to the non-vectorized version of WHFast. https://fitnessgravesyardes.shop/product-category/bottom-bracket-kit/
