PROCESS MIGRATION METHOD, COMPUTER SYSTEM OPERATING TO EXECUTE PROCESS MIGRATION, INTERMEDIATE CALCULATION RESOURCES IN SUCH SYSTEM, AND METHOD OF SELECTING CALCULATION RESOURCES BEFORE PARTITIONING FOR PROCESS MIGRATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method of migrating implementation of a computer program, capable of being flexibly used for different situations and paying attention to difficulty of migration and arbitrary synchronization.;SOLUTION: A process migration method comprises: implementing a computer program by current calculation resources 10 in a current partition of a parallel processes for calculations; executing at least one calculation by each of the parallel processes; transmitting current partition data to intermediate calculation resources 20; calculating new partition data including new allocation of calculations to the processes by changed calculation resources 30 using the intermediate calculation resources 20; transmitting the new partition data to the changed calculation resources 30; and thereby migrating process implementation to the changed calculation resources 30.;COPYRIGHT: (C)2015,JPO&INPIT
