METHOD OF CALCULATING PROCESSOR UTILIZATION RATE IN SMT PROCESSOR

摘要

The method of calculating the processor utilization for each of logical processors in a computer, including the steps of: dividing the computation interval in which the processor utilization by each logical processor is to be calculated into a single task mode (ST) execution interval and a multitask mode (MT) execution interval, appropriately calculating them based on the before-and-after relation between two times; and adding the MT execution interval multiplied by a predetermined MT mode processor resource assignment ratio to the ST mode execution interval to obtain the processor utilization for the calculation-targeted logical processor in the computation interval.
