Recent MKL will generate reasonable code for Zen if you set a magic environment variable, but it was very limited (possibly only sgemm and/or dgemm when I looked). Once you've generated AVX2 with a reasonable block size, you're most of the way there. But why not just use a free BLAS which has been specifically tuned for your AMD CPU (and probably your Intel one)?
- user5994461 5y agoNope, they removed support for the magic environment variable in the latest MKL release.
- gnufx 5y agoI stand corrected. No loss, anyway. (I probably saw it in oneapi from sometime last year, and was surprised.)
