ACTIVITY RECORDING SYSTEM FOR A CONCURRENT SOFTWARE ENVIRONMENT

摘要

An activity recording system for a concurrent software environment executing software threads in a computer system, the activity recording system comprising: a thread state indicator for recording an indication of a synchronisation state of a software thread in which the software thread ceases to execute in a processor of the computer system, the indication being associated with an identification of the software thread; a time profiler for identifying a processor of the computer system being idle and recording an indication that the processor is idle; a dispatch monitor for identifying the dispatch of the software thread to the processor and, responsive to the indication that the processor is idle and the indication of a synchronisation state of the software thread, generating a record attributing the idleness of the processor to the software thread and the indicated synchronisation state.
