The ad hominem and profanity isn't even correct about OpenBLAS. There's nothing interesting in the lack of Skylake support, as is obvious from the open issue for KNL support. That might even be interesting for the pointers it contains to KNL and SKX GEMM. OpenBLAS 2.18 certainly does use AVX(2) on appropriate CPUs. If doesn't detect micro-architectures that didn't exist at the time, it hardly a bug, and the correct solution would be to persuade the Ubuntu maintainer to provide the "hardware enablement", or to use BLIS. If tutorials tell you to install "libopenblas" they're wrong because that package doesn't exist.
