Abstract
A processing system features a first processing core to operate in a first node, a second processing core to operate in a second node, and random access memory (RAM) responsive to the first and second processing cores. The processing system also features control logic to perform operations such as (a) automatically updating a resident set size (RSS) counter to correspond to the RSS for the thread on the first node in response to allocation of a page frame for a thread in the first node, and (b) using the RSS counter to predict migration overhead when determining whether the thread should be migrated from the first processing core to the second processing core. Other embodiments are described and claimed.
