ABSTRACT:
An information processing system is configured to schedule tasks to a plurality of processors using processor performance information. For example, the maximum performance level of each of the processors, the current performance level of each of the processors, and the number of processors can be used to schedule tasks to one or more of the processors. A task distribution frequency which takes this information into account can be useful. One such task distribution frequency fiis calculated so that fi=Di/ΣDiwhere i ranges from 1-N and Di=MPi/CPi/N, where MPiis a maximum performance level for the processor i, CPiis a current performance level for the processor i, and N is the number of processors. Tasks are distributed according to the task distribution frequency fi.
