      AMD Squeezing Out More More ROCm/HIP Performance With New Device-Side PGO

      news.movim.eu / Phoronix • 20:03

    Compiler profile guided optimization (PGO) techniques have paid off well for increasing CPU performance via application/workload-specific profiles fed back to the compiler to make more informed decisions. AMD compiler engineers have been working on crafting device-side PGO for their AMDGPU LLVM back-end for allowing ROCm/HIP workloads to achieve greater GPU performance. An initial merge request is now open for upstream LLVM...

      Revisiting The Linux 6.19 Performance With "NEXT_BUDDY" Now Disabled

      news.movim.eu / Phoronix • 15:24

    Back at the start of the Linux 6.19 kernel cycle I ran benchmarks showing some scheduler performance regressions with the new kernel. Fortunately, two weeks out from the Linux 6.19 stable release, merged this weekend was disabling the scheduler's NEXT_BUDDY feature due to performance regressions. Here are some fresh benchmarks looking at the latest Linux 6.19 Git state with/without NEXT_BUDDY and comparing it to Linux 6.18 stable for reference.
