Abstract:
1. A processor system optimization supporting apparatus to support optimization of a processor system including multiple processors, comprising: an information obtainment unit configured to read, from memory, trace information of the processor system and performance information corresponding to the trace information; an information analysis unit configured to analyze the trace information and the performance information that are read; and an optimization method output unit configured to output a method of optimizing the system in response to a result of the analysis; wherein: the information analysis unit obtains a performance factor of the system as a result of the analysis; the processor system is a multitasking system; tasks in the multitasking system belong to one of the processors; each individual task in the multitasking system waits for termination of a communication between another task in the multitasking system and another processor to start communication with the other processor; and while obtaining the trace information, the information analysis unit obtains, as the performance factor, a value of a sum of time periods during which each individual task waits to start communication with the other processor.
