摘要：
In a multiprocessor system where each processor has the capacity to executing multiple hardware threads, a processor capacity monitor calculates a logical usage percentage of each of the available hardware threads. The processor capacity monitor calculates a physical usage percentage of each of the processors by each of the available threads. The processor capacity monitor calculate a percentage usage of a total capacity of the physical processors from the logical usage percentages and the physical usage percentages, such that the percentage usage reflects the actual use of the physical processors independent of which of the threads is used.
