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…

In addition to the review embargo lift today for Genoa-X with our AMD EPYC 9684X benchmarks, the lift is also today on the new AMD EPYC “Bergamo” processors for offering up to 128 cores / 256 threads per socket using the new Zen 4C core. In this article is an initial look at the performance provided by the AMD EPYC 9754 128-core processors.

Last year AMD launched Milan-X as their first server processors with 3D V-Cache. The performance uplift from the 768MB of L3 cache per socket was phenomenal, but now here we are today with the next-generation successor: Genoa-X. The flagship EPYC 9684X is the new leader for HPC and AI performance as in addition to a 1.1GB L3 cache it leverages AMD’s modern Zen 4 micro-architecture with AVX-512, 12 channel DDR5 memory, and other improvements found with existing EPYC 9004 series processors to easily triumph as the new best CPU for high performance computing from CFD and FEA to dozens of other scientific workloads. Here are the first benchmarks of the AMD EPYC 9684X processors.

There’s a lovely new Linux kernel patch series out that’s big in working on a major clean-up of the x86 APIC code (or “decrapification” as it’s called in the patches) and also bringing up for discussion the idea of killing off x86 32-bit support. It’s unlikely the x86 32-bit support will be removed right now, which is “just museum pieces”, but as an alternative would be making it SMP-only to at least remove the uni-processor code paths…

While Intel Arc Graphics continue enjoying performance optimizations with the open-source Linux graphics driver stack, the major limitation facing Arc Graphics on Linux right now for gamers is the lack of sparse residency support that is needed for running many newer games on Linux with Intel graphics — particularly newer Windows D3D12 titles running on Linux via Valve’s Steam Play. It’s been a long known limitation and will hopefully be addressed once the Intel Xe kernel driver is introduced, but at least as an interim solution there is now “fake” sparse support being implemented…
