64K Kernel Page Size Performance Benefits For HPC Shown With NVIDIA's GH200 Grace CPU
The Linux 6.5 to 6.8 upgrade on the GH200 didn't tend to make too much of a difference while quite quickly the 64K kernel build began to show better performance over the 4K kernel.
In some workloads the 64K kernel increased the CPU performance by several percent but not necessarily enough to change the outcome in regards to the EPYC and Xeon CPU positioning.
Seeing several percent improvements isn't out of the ordinary for the ARM64 4K vs. 64K performance and jives with testing I've done on other ARM server hardware in the past like with Ampere Computing.
The LULESH hydrodynamics software saw a huge boost in performance out of the 64K page size kernel build.
