Hi Frederik, I think backporting openblas is possible, and it won't require much work. Recently I've worked on some similar packages. intel-mkl has been backported to stable but I suspect whether MKL's performance is guaranteed on AMD CPUs. Another new BLAS library called BLIS is waiting in the NEW queue, which ships AMD Zen CPU support.
I CC'ed Sébastien in case he didn't subscribe to the backports list. Science team is also CC'ed because we're talking about BLAS.
