In some workloads the 64K kernel use was enough to bump the GPTshop.ai GH200 positioning to the front of the race against the tested x86_64 server processors.
👁 ACES DGEMM benchmark with settings of Sustained Floating-Point Rate. EPYC 9754 2P was the fastest.
ACES DGEMM was another nice HPC workload showing off the big uplift possible if running a 64K page size kernel on AArch64 hardware.
Going from Linux 6.5 to 6.8 alone wasn't much of a difference but the 64K kernel page size continues to prove very beneficial for large ARM servers/HPC.
Code compilation workloads also improved as well with the 64K kernel page size.
