摘要

PROBLEM TO BE SOLVED: To provide a distributed synchronous processing system capable of suppressing a standby time and reducing a processing time.;SOLUTION: A distributed synchronous system is a system connecting a plurality of processing servers for operating one or more distributed processing units which is a virtual machine and performing calculation processing in synchronization between the distributed processing units. The processing server 30 includes control means 322 for sending a late message to another processing server if a distributed processing unit of the processing server is in a standby time between a distributed processing unit on another processing server, and a resource operating a distributed processing unit on another processing server exists, and replica control means 323 for constructing a replica on its own processing server 30 and performing calculation processing at a stage of receiving a replica control message instructing construction of the replica of the distributed processing unit that has generated a waiting state from another processing server to the late message.;SELECTED DRAWING: Figure 6;COPYRIGHT: (C)2019,JPO&INPIT
