PARALLEL PROCESS SCHEDULING METHOD IN PARALLEL COMPUTER AND PROCESSOR FOR PARALLEL COMPUTER

摘要

PROBLEM TO BE SOLVED: To realize a cooperative scheduling without deteriorating the throughput performance of the system of a parallel computer at the time of executing one job as a parallel process while it is synchronized for respective steps by more than two processors in a parallel computer constituted by connecting plural processors so that they can mutually make communication. ;SOLUTION: When the parallel process in the middle of execution becomes a parallel synchronism waiting state, an inactivating means 4 makes the parallel process inactive and inhibits the allocation of the parallel process. An allocation function 6 allocates the process of the other job which can be executed. When a condition which is set by a condition setting function 5 during the execution of the other job is satisfied, an allocation generation function 7 generates an allocation signal for a processing during execution at present. An activating function 8 activates the parallel process in the parallel synchronism waiting state and resumes the allocation of the parallel process.;COPYRIGHT: (C)1997,JPO
