Optimizing The Linux Kernel With PGO Can Yield ~3% Benefit For HPC Workloads
While the Linux kernel itself may not be often viewed as a bottleneck to typical high performance computing (HPC) workloads, optimizing the Linux kernel with Profile Guided Optimizations (PGO) can prove worthwhile for those seeking maximum performance potential
A presentation this past weekend at FOSDEM 2025 is highlighting around a 3% performance gain for HPC software compiled with PGO enabled.
