Aiming at enabling an analysis of relationship between a task transition and performance information such as mis-caching in a multiprocessor system and clearly identifying a relationship between a degree of parallelism and the task transition of the system processing, trace information and performance information corresponding to the trace information are obtained from memory, and the task transition state and performance information based on the trace information are displayed by superimposing on the transition chart. A degree of parallelism corresponding to an operation state of a plurality of processors is calculated on the basis of the trace information, and the degree of parallelism is displayed by being temporally synchronized with the task transition chart.
