64K Kernel Page Size Performance Benefits For HPC Shown With NVIDIA's GH200 Grace CPU

Phoronix - Wed, 02/28/2024 - 01:00
By default the AArch64 kernel on Ubuntu and other Linux distributions tend to default to a standard 4K page size but for newer AArch64 hardware especially in the server/HPC space, there can be great benefits to using a 64K page size. As it's been a while since I last ran any 64-bit ARM 4K vs. 64K kernel page size benchmarks, while having remote access to the NVIDIA GH200 I ran a fresh comparison for looking at the performance advantages to switching over to a 64K page size kernel. These new 64K kernel numbers are shown alongside the recent AMD EPYC and Intel Xeon CPU reference benchmark results for a look at how the 4K vs. 64K page size affects the overall computing landscape.

Intel HFI Driver Can "Save Tons Of CPU Cycles" By Only Enabling Itself When Needed

Phoronix - Tue, 02/27/2024 - 19:42
The Linux kernel has supported the Intel Hardware Feedback Interface "HFI" via the "intel_hfi" driver since 2022 for bettering supporting Core hybrid processors. The Intel HFI can be used for communicating performance and energy efficiency capabilities of individual CPU cores of the system. In turn the Linux kernel can leverage Intel HFI details for better task placement among the available CPU cores/threads. With a new patch series, the Intel HFI driver can "save tons of CPU cycles" by only enabling it when needed...
