“Tuning packages for a CPU micro-architecture”

[Ludovic Courtès]

Hello there, and happy new year where applicable!

This blog post discusses the new ‘--tune’ option and “package
multi-versioning” as a way of achieving performance without giving up on
reproducibility:

I’ve found reproducibility to be often depicted as being detrimental to
performance in HPC circles, so this is a contribution to suggest
otherwise.
