One of my stranger uses for #NBody and solutions to Lambert's problem, ICBM+RV trajectories for a massive counterforce and countervalue attack. (one of the home-brew games took place immediately around such an attack)

🚨 New paper!

We re-implement the symplectic WHFast integrator for planetary systems using #AVX512 instructions. We get an almost 5x speedup for a typical integration of the Solar system.

This is a big deal because no matter how much money you spend buying a cluster or GPUs, you just cannot accelerate small N-body integrations. They are inherently sequential. But now a 5 GYr simulation that used to take a week to finish only takes 1.4 days.

I verify my #NBody simulations that I use in #Traveller and #2300AD against real-world spacecraft. Here is my Voyager 1 Io flyby, simulated and all rendered in #Mathematica
