Abstract
An embodiment of the invention provides an apparatus and method for accurate measurement of utilizations in a hardware multithreaded processor core. The apparatus and method perform the acts including: determining idle time spent cycles which are cycles that are spent in idle by a hardware thread in a processor core; determining idle consumed cycles which are cycles that are consumed in the idle time spent cycles, by the hardware thread; and determining at least one of a processor core utilization and a logical processor utilization based upon at least one of the idle time spent cycles (d1) and idle consumed cycles (d3).
