A plurality of barrier blades, a barrier blade identification information storage unit, and a barrier blade identification information selection unit are provided. The plurality of barrier blades synchronize, using a synchronization address set for a plurality of arithmetic processing units, the plurality of arithmetic processing units. The barrier blade identification information storage unit holds barrier blade identification information to identify the barrier blade corresponding to synchronization address identification information to identify the synchronization address, for each of the plurality of arithmetic processing units. When synchronization address identification information is input, the barrier blade identification information selection unit selects and outputs barrier blade identification information corresponding to the input synchronization address identification information, among barrier blade identification information held by the barrier blade identification information storage unit. |
