I am currently benchmarking a few AMD systems in our infrastructure.
I compiled the hpl 2.3 linpack benchmark using amd-blis-1.3 and I only get about 61 GFlops/s.
I already had a look at the HPC tuning guide for EPYC Processors and changed the HPL.dat accordingly but in this case the benchmark runs forever (ok, well, didn't returned a result after at least 3 hours)
Is there something I'm missing?
