Making Rust a perfect fit for high-performance computations

Hello, Rust community!

My name is Hadrien and I am a software performance engineer in a particle physics lab. My daily job is to figure out ways to make scientific software use hardware more efficiently without sacrificing its correctness, primarily by adapting old-ish codebases to the changes that occured in the software and computing landscape since the days where they were designed:

  • CPU clock rates and instruction-level parallelism stopped going up, so optimizing code is now more important.
  • Multi-core CPUs went from an exotic niche to a cheap commodity, so parallelism is not optional anymore.
  • Core counts grow faster than RAM prices go down, so multi-processing is not enough anymore.
  • SIMD vectors become wider and wider, so vectorization is not a gimmick anymore.
