Hi,
We're a company that develops audio processing products, that heavily depend on Intel's Math Kernel Library (MKL) for optimizations.
We've been using MKL for a long time now, enjoying great optimization on both AMD and Intel CPUs. Now that it's time to upgrade to a newer MKL version (2021 or 2022), we're experiencing a degradation by a factor of 3 when running on AMD, while Intel processors have the same good performance as before.
It is important to mention that we used to use Intel's "secret" environment variable that overcame degradation on AMD, however this variable is no longer available with the newer MKL versions.
Is there an AMD specialist we can consult with? I assume this problem is well known around the AMD development community.
Thanks,
Gil.
