I don't understand why people use MKL on AMD hardware rather than AMD's (current) library, which is basically upstream BLIS for those architectures; their old one from the Operton era wasn't good. OpenBLAS has been largely competitive with MKL even on Intel anyway over many years, and the MKL licence used not to allow the sort of use people made of it. MKL is infinitely slower than OpenBLAS/BLIS averaged over the hardware relevant to HPC, like the POWER system I support.
