Linux 6.17 Improves NUMA Locality For SMP Call Rather Than Deferring To Random CPU Core

After all of these years of Linux dominating the high performance computing (HPC) space and other industries, one might think (most) all the interesting performance nuggets have been uncovered and well thought out and robust fallbacks in place across all important code paths. As we showcase almost each cycle, interesting new performance bits to be uncovered within the Linux kernel. For Linux 6.17 thanks to a NVIDIA engineer is applying a better fallback for NUMA locality rather than simply picking a random CPU core...
