PROBLEM TO BE SOLVED: To provide a distributed simulation controller capable of improving the performance of the entire distributed simulation by executing simulation control functions for performing the control of transmission and reception among simulators and time synchronization in parallel. ;SOLUTION: The simulation control functions 6'a-6'c for performing the control of the transmission and the reception among the simulators 1a-1c and the time synchronization and distributed shared memories 7'a-7'c for simulation data sharing data to be transmitted and received and the simulation data such as the states of the respective simulators 1a-1c or the like are distributed and arranged. Then, this controller is constituted of a mechanism for keeping the contents of all the distributed shared memories 7'a-7'c for the simulation data the same by connecting the respective distributed shared memories 7'a-7'c for the simulation data by a network 5 and transmitting the change of the respective contents through the network 5 to all the other distributed shared memories 7'a-7'c for the simulation data.;COPYRIGHT: (C)1999,JPO
