Abstract:
1. A method of indicating usage in a system, including: determining a first value based at least in part on active hardware thread information associated with a measure of activity of a plurality of hardware threads in a processor core over an interval of time, wherein the active hardware thread information includes information about the amount of idle time of at least one of the hardware threads during the interval of time; determining a second value based at least in part on information related to a decreasing ability of the processor core to increase throughput when the number of idle hardware threads is reduced; determining the usage in the system, including selecting one of the first value and the second value, the usage being indicative of a ratio of a rate at which the system has performed a workload over the interval of time to a rate at which the system would perform the workload if the system were continuously executing the workload over the same interval of time, wherein at least one of the hardware threads is idle for at least a portion of the interval of time.
