      The Open64 Compiler Seeing Some Recent Changes, clang2whirl Clang Open64 Front-End

      news.movim.eu / Phoronix • 21 July, 2023

    Prior to LLVM/Clang becoming so popular within organizations and it maturing well on x86_64, AArch64, and other architectures, Open64 was once quite popular in areas now dominated by LLVM and GCC. Open64 had been popular with academic researchers, AMD even maintained their Open64 optimized compiler a decade prior to the LLVM-based AOCC, and was quite popular in the HPC space. Surprisingly there's been some recent activity on the Open64 compiler code...

      Linux 6.6 To Deal With Unresponsive Intel QAT Devices

      news.movim.eu / Phoronix • 20 July, 2023

    Linux has supported Quick Assist Technology (QAT) devices from the start whether it be QAT PCIe adapters or QAT support found within select Atom and Xeon CPUs as well as the latest-generation Sapphire Rapids CPUs. Only now though with the upcoming Linux 6.6 kernel is it adding a heartbeat feature for determining if a QAT device becomes unresponsive so that it can be acted upon...

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

      news.movim.eu / Phoronix • 20 July, 2023

    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

      news.movim.eu / Phoronix • 20 July, 2023

    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...
