Abstract
Methods, apparatuses, and computer-readable storage media are disclosed for reducing power by reducing hardware-thread toggling in a multi-processor. In a particular embodiment, a method is disclosed that includes collecting data from a plurality of software threads being processed by a processor, where the data for each of the events includes a value of an associated clock cycle counter upon occurrence of the event. Data is correlated for the events occurring for each of the plurality of threads by starting each of a plurality of clock cycle counters associated with the software threads at a common time. Alternatively, data is correlated for the events by logging a synchronizing event within each of the plurality of software threads.
