HYBRID PARALLEL PROCESSING SYSTEM, HYBRID PARALLEL PROCESSING METHOD, AND COMPUTER PROGRAM

PROBLEM TO BE SOLVED: To realize effective parallel processing in hybrid parallel processing.SOLUTION: The hybrid parallel processing system comprises a plurality of processes which are processed in parallel. Each of the processes includes: one or more threads for executing processing allocated to the process; data transfer processing means for performing data transfer processing between the processes; and thread number reset means for resetting the number of threads. The data transfer processing means includes transfer wait time measurement means for measuring transfer wait time in the data transfer processing between the processes and transmits/receives the transfer wait time to/from other processes. The thread number reset means resets the number of threads on the basis of the transfer wait time.
