For the concept, maybe
<https://hpc.guix.info/blog/2022/01/tuning-packages-for-a-cpu-micro-architecture/>
, which is about combining high performance with reproducibility using
the (Guix-specific) --tune package transformation.  To implement run-
time detection, the following could be useful:

* Guix article:
<https://hpc.guix.info/blog/2018/01/pre-built-binaries-vs-performance/>
* LWN article: <https://lwn.net/Articles/691932/>.

Greetings,
Maxime.
