PURPOSE:To immediately execute proper processing even when an error is generated in a parallel computer (PE) and to rapidly attain synchronism between plural PEs by detecting all status at the time of forming the synchronism of all PEs in respect to a synchronism/status/stable state detecting method in a system for connecting many PEs through a network and synchronizing them. CONSTITUTION:This synchronism control system is provided with plural status request register means 2 prepared in individual PEs so as to independently output status requests and store the request signals, a status deciding means 4 for deciding the existence of requests from all PE status request registers, a status distributing means 5 for distributing status based upon the decided result, and a status detecting register means 3 for detecting the status based upon the distributed decision result and the output of a synchronism detecting register means 1 and constituted of detecting the status of all the PEs when the synchronism of all the PEs is established. |
