摘要

PROBLEM TO BE SOLVED: To perform calculation using start time of inter-process communication without changing behavior of parallel applications during execution of the parallel applications.SOLUTION: A calculation processing device executes a program, and gives first sequence information to first start time a first process included in the program has started first inter-process communication. Then, the calculation processing device writes the first start time and the first sequence information in a main storage device. If second sequence information given to second start time a second process has started second inter-process communication is newer than the first sequence information, a calculation unit 411 in a communication control device 401 does not perform calculation using the first start time. On the other hand, the second sequence information corresponds to the first sequence information, the calculation unit 411 outputs a calculation result by performing calculation using the first start time and the second start time.
