Patent number: 9465675Abstract: An arithmetic processing device executes a program, and gives first sequence information to a first start time when a first process included in the program starts a first interprocess communication. Then, the first start time and the first sequence information are written in a main storage device. When second sequence information given to a second start time when a second process starts a second interprocess communication is newer than the first sequence information, an operational circuit in a communication control device does not carry out an operation using the first start time. On the other hand, when the second sequence information corresponds to the first sequence information, the operational circuit carries out an operation using the first start time and the second start time and outputs the operation result.Type: GrantFiled: November 12, 2014Date of Patent: October 11, 2016Assignee: FUJITSU LIMITEDInventors: Hideki Miwa, Ikuo Miyoshi
