US 9,870,275 B2 · Processor thread management

Abstract

Provided are a computer program product, system, and method for managing processor threads of a plurality of processors. In one embodiment, a parameter of performance of the computing system is measured, and the configurations of one or more processor nodes are dynamically adjusted as a function of the measured parameter of performance. In this manner, the number of processor threads being concurrently executed by the plurality of processor nodes of the computing system may be dynamically adjusted in real time as the system operates to improve the performance of the system as it operates under various operating conditions. It is appreciated that systems employing processor thread management in accordance with the present description may provide other features in addition to or instead of those described herein, depending upon the particular application.
