Abstract: A method is described. The method includes determining that a memory page is in one of an active state and an idle state from meta data that is maintained for the memory page. The method includes recording a past history of active/idle state determinations that were previously made for the memory page. The method includes training a neural network on the past history of the memory page. The method includes using the neural network to predict one of a future active state and future idle state for the memory page. The method includes determining a location for the memory page based on the past history of the memory page and the predicted future state of the memory page, the location being one of a faster memory and a slower memory. The method includes moving the memory page to the location from the other one of the faster memory and the slower memory.

Abstract: An apparatus of a computing system, the computing system, a method to be performed at the apparatus, and a machine-readable storage medium. The apparatus includes control circuitry to: perform a page walk operation on a page table structure of a pooled memory; based on the page walk operation, determine page table entries (PTEs) corresponding to a workload to be executed by the computing system; and during a time interval not including a page walk operation by the control circuitry, perform a plurality of sampling operations, individual ones of the sampling operations including determining PTE metadata corresponding to at least some of the PTEs.
