A Look At How The Linux Performance Has Evolved Since The AMD EPYC Launch

In the case of NASA's NAS Parallel Benchmarks (NPB), there were very surprising boosts to see in performance on AMD EPYC going from Ubuntu 17.04 to 19.04 and to a smaller extent even with the upgrade to Linux 5.2. The NPB improvements likely come from Znver1 optimizations made between GCC6 and GCC8 as well as kernel improvements benefiting multi-process workloads.

Several of the Parboil and Rodinia OpenMP-threaded scientific test cases were also showing quite measurable improvements from Ubuntu 17.04 to Ubuntu 19.04.

The HPCG HPC benchmark performance was also improving little by little.
