Region-weighted accounting of multi-threaded processor core according to dispatch state

摘要

According to one embodiment of the present disclosure, an approach is provided in which a thread is selected from multiple active threads, along with a corresponding weighting value. Computational logic determines whether one of the multiple threads is dispatching an instruction and, if so, computes a dispatch weighting value using the selected weighting value and a dispatch factor that indicates a weighting adjustment of the selected weighting value. In turn, a resource utilization value of the selected thread is computed using the dispatch weighting value.

1. A method comprising:
selecting a thread from a plurality of active threads on a processor; selecting a weighting value according to a thread state of the selected thread; determining whether one of the plurality of active threads is dispatching an instruction; in response to determining that one of the plurality of active threads is dispatching an instruction, computing, via one or more mathematical computations, a dispatch weighting value corresponding to the selected thread using the weighting value and a dispatch factor, wherein the dispatch factor indicates a weighting adjustment of the weighting value; and computing a resource utilization value of the selected thread using the computed dispatch weighting value.
