Speculative NUMA Fault Support Proposed For Improving Tiered Memory Linux Performance

This year there has been a lot of Linux kernel work around improving the handling of tiered memory servers, namely those with traditional system RAM augmented by Intel Optane DC persistent memory. There has been work to demote pages during reclamation to the slower persistent memory, improving NUMA balancing around such systems to optimize memory placement, transparent page placement and related work around tiered memory Linux servers...
