Linux's Proposed Cache Aware Scheduling Benchmarks Show Big Potential On AMD EPYC Turin

23 octobre 2025 à 14:50
The past number of months has seen a lot of work by Intel Linux kernel engineers on cache-aware scheduling / load balancing for helping modern CPUs that have multiple caches. With cache aware scheduling, tasks that will likely share resources could be aggregated into the same cache domain to enjoy better cache locality. With the cache aware scheduling patches recently updated and now working past the "request for comments" stage, I was eager to try out these new patches. Especially with a 44% time reduction reported for one of the benchmarks, I was eager to run some tests and the first of those results are being shared today.

Qualcomm Plumbing "SSR" Support To Deal With Crashes On AI Accelerators

LLVM Lands Some Long Overdue Tuning Optimizations For AMD Zen 4

22 octobre 2025 à 13:36
Merged today to the LLVM/Clang compiler codebase are some long overdue adjustments to the AMD Zen 4 "znver4" CPU model for more accurately assessing various latency timings and micro-ops. These values were initially copied over from the Zen 3 (znver3) target but never adjusted properly for Zen 4 until now when an independent contributor took to sorting it out...
