Subject: “Tuning packages for a CPU micro-architecture”
Date: Thu, 06 Jan 2022 17:22:06 +0100	[thread overview]
Message-ID: <87fsq0eswh.fsf@inria.fr> (raw)

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:

  https://hpc.guix.info/blog/2022/01/tuning-packages-for-a-cpu-micro-architecture/

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