What is Jenkins X?

Not a simple answer to the question:

• a CLI
• a collection of community tools
• a way of working

Requirements for going through all these steps:

• A free GitHub organization with 2 free users (one will approve PRs and the other is a bot user used by the pipelines) OR just 2 free users (one will approve PRs and the other is a bot user used bythe pipelines)

HadrienG2

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.
