8-Way Linux Distribution Benchmarks On The AMD EPYC 7742 2P Server

Clear Linux tended to have measurable advantages in the OpenMP tests like Parboil compared to the other supported Linux distributions.

In some of the scientific workloads like CP2K molecular dynamics and NAMD, none of the tested operating systems imposed any bottlenecks or had any meaningful performance differences on this 256-thread AMD server.

With John The Ripper, Ubuntu 19.10 and Fedora 30 with their newest software components surprisingly had a performance penalty compared to the other Linux distributions tested while the rolling-release Clear Linux was unaffected by the slowdowns found on Ubuntu 19.10 development and the updated Fedora 30.

Fedora 30 had another loss when it came to running the TTSIOD renderer on the CPU while Clear Linux and openSUSE were performing the best.

OpenSUSE and Clear Linux were also performing very well with the Intel SVT video encoders.
