I’m asking because preloading different BLAS libraries is a thing. If this works then we can ask people to just pick their favourite BLAS library variant and preload it. We don’t need to build all combinations of library variants and applications. > I think channels actually should make a difference if we don't cater > in default Guix for such use cases. I think channels (and really: alternative build farms) do make sense for tuned builds. -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net
