PROBLEM TO BE SOLVED: To provide a technique in which when execution of synchronous processing is repeated two or more times, a result of each execution of the synchronous processing at each processing device is reflected to subsequent execution of the synchronous processing.SOLUTION: Each CPU 0-2 specifies a synchronous point when a queuing count value of a register 35 or 36 and a queuing object CPU number of a register 31 coincide with each other. As a result of execution of a first test in first test processing at S21, the CPU 2 determines that it does not execute a second test in second test processing at S22, and updates the queuing object CPU number in the register 31 from 3 to 2 and update. The CPUs 0 and 1, by execution of the second test in the second test processing, update a queuing count number in the register 35 from 0 to 1, and from 1 to 2 sequentially. As a result, the queuing count number coincides with the queuing object CPU number. Thereby, each CPU 0-2 autonomously selects whether or not a next test should be executed, and updates the queuing object CPU number as necessary. |
