SMT Proves Worthwhile Option For 128-Core AMD EPYC "Bergamo" CPUs
The CP2K molecular dynamics package was a bit mixed with no real change for SMT when running in the 1P configuration but in 2P there was a measurable benefit to having SMT enabled.
Similar to CP2K, with NAMD as well there was a nice speed-up when running EPYC 9754 2P with SMT enabled while for 1P the results were rather flat.
Libxsmm also saw some benefit from SMT only when running in a 2P configuration.
The Xmrig CPU miner with Wownero did benefit greatly from the SMT support found with the Zen 4C cores.
All the John The Ripper OpenMP-threaded tests benefited a lot from SMT found with the Bergamo server processor.
SMT improved the power efficiency for John The Ripper with the CPU power consumption only going up slightly.
