NVIDIA engineers have been working on NUMA distance metrics within the Linux kernel to replace the simple local/remote NUMA preference interface currently used by some drivers for NUMA-aware memory allocations. In their testing this improved NUMA distance handling is leading to "significant performance implications" for throughput and CPU utilization...

Following the recent discussions about -O3'ing the Linux kernel and other compiler optimizations, a request came in to see some fresh GCC compiler optimization benchmarks with the recently released GCC 12. So here is a fresh look at various GCC optimization levels up through -Ofast as well as with link-time optimizations (LTO) and "-march=native" tuning on the new GCC 12 with the mature AMD Ryzen Threadripper 3990X platform.

Added to Intel's documentation in late 2020 and initial kernel patches out since early 2021, Intel has been slowly working on Linear Address Masking (LAM) support for the Linux kernel. Out this past week was finally the latest iteration of this work for leveraging untranslated address bits of 64-bit linear addresses to be used for storing arbitrary software metadata...
