To confirm the distribution volume of a load for parallelization with numerics, and to support the parallelization tuning of a parallel execution program.

A program to be analyzed execution number of time measuring means 12 accumulates the number of times of execution in a count area in response to a count instruction inserted into a program to be analyzed at the time of translation to measure the number of times of execution of an execution sentence by each of parallel execution units. An execution number of time measurement result analyzing means 13 measures the mean number of rotation of a loop from the measurement result of the number of times of execution, and calculates a performance improvement rate when changing the degree of parallelization. Also, the number of times of execution of the execution sentence in each procedure in programs executed in parallel and the number of times of execution of the execution sentence by each of the parallel execution units of each loop are calculated, and the calculation results are displayed in the order of the larger number of times, and information indicating the balance of the number of times of execution between the parallel execution units.
