Do you know about OpenBLAS alternative Mir GLAS? (github.com)

There's a bunch of POCs about writing a BLAS equivalent in Julia. Theoretically, one day it could be a viable alternative. See https://discourse.julialang.org/t/ann-paddedmatrices-jl-juli...

One of the issues with the various OSS BLAS/Lapack implementations is that they're inevitably researched heavily for a while and then fall out of maintenance. If you're a commercial developer, unless performance is absolutely critical, you're better off just paying and using MKL as at least it's stable.
