ABSTRACT:
An inter-processor synchronization control system in a distributed memory type parallel computer comprises a unit for detecting an establishment of the synchronization of all PEs, a status request register unit provided for each PE for independently issuing a status request through a status request signal, a unit for determining the issues of requests from status request registers of all PEs, a unit for distributing the determination to all PEs and a status detecting register for detecting the status according to the distributed determination and the output of the synchronization establishment detection unit. The inter-processor synchronous control system detects the status of all PEs when the synchronization is established in all PEs.
