SMT Proves Worthwhile Option For 128-Core AMD EPYC "Bergamo" CPUs

Phoronix - Thu, 07/20/2023 - 22:57
While the AMD EPYC 9754 "Bergamo" processor is impressive for having 128 physical Zen 4C cores, it also has Simultaneous Multi-Threading (SMT) to provide for 256 threads per socket. Meanwhile with Ampere Altra Max and AmpereOne there is no SMT and it's likely Intel's upcoming Sierra Forest will also lack SMT (Hyper Threading) given it's an E-core-only design. But that led to my curiosity over the SMT impact for Bergamo on power and performance when leveraging SMT for the 128-core flagship EPYC 9754. Today's Bergamo benchmarking is looking at SMT on and off for both 1P and 2P server configurations.

Alibaba Eyes Linux CPU Scheduler Changes To Better Handle QEMU With SMT/HT Threads

Phoronix - Thu, 07/20/2023 - 18:13
There is a phenomenon where running a multi-threaded workload inside a virtual machine (VM) with Simultaneously Multi-Threading (SMT / Intel Hyper Threading) that a sibling thread could find itself busy while the CPU core is idle. A new Linux CFS patch series aims to make the scheduler better adapt to the QEMU topology...
