Abstract

A system and method for improving efficiency of a multi-core architecture includes, in accordance with a workload, determining a number of cores to shut down based upon a metric that combines parameters to represent operational efficiency. Threads of the workload are reassigned to cores remaining active by assigning threads based on priority constraints and thread execution history to improve the operational efficiency of the multi-core architecture.
