  • Distributed processing control method and distributed processing system
    Patent number: 5625832
    Abstract: A distributed control method and distributed processing system to decrease data communication overhead and to execute a program efficiently. One of processors at which data arrives in a multiprocessing system is selected by a polling process (310 to 312). All data which arrives at the selected processor is received therefrom to fill a control table of sending and receiving data and a control table of calculation sets with marks for indicating the completion of data receipt (314 to 316). Data to be sent is sent so that the control table of sending and receiving data is marked to indicate the completion of data sending (318 to 320). If data has not yet arrived during polling, required data is sent to all processors (322). The execution of actual calculations using array processes is effected by using calculation sets such that the control table of calculation sets is marked indicating the completion of calculation.
