NettetWhich is a kind of mostly frequently accessed (MFU) algorithm. In NUMA balancing memory tiering mode, if there are hot pages in slow memory node and cold pages in fast memory node, we need to promote/demote hot/cold pages between the fast and cold memory nodes. A choice is to promote/demote as fast as possible. NettetPMDK provides a toolkit for memory hierarchy, memory caching, virtual memory and memory tiering. PMDK-PMEM toolkit provides operational modes in either app direct mode or memory mode. App Direct Mode provides memory persistent, high availability less downtime and significantly faster storage.

But the CPU cycles and memory bandwidth consumed by the high promoting/demoting throughput will hurt the latency of some workload because of accessing inflating and slow memory bandwidth contention. A way to resolve this issue is to restrict the max promoting/demoting throughput.
