Software-defined far memory in warehouse scale computers

The Morning Paper

We focus on a definition that draws from the following two principles: (1) the value of temporal locality, by classifying as cold a memory page that has not been accessed beyond a threshold of T seconds; (2) a proxy for the application effect of far memory, by measuring the rate of accesses to cold memory pages, called promotion rate.
