Abstract

A thread switch handler is provided which monitors performance characteristics of a processor executing instructions from two or more threads of an application. The thread switch handler detects when the processor has switched between a first and second thread and is capable of reading the performance registers available in many commercial processors at or about that time. The data that is read from the performance registers at each thread switch represents performance characteristics of the processor on a per-thread basis.
