MULTIPROCESSOR PARALLEL COMPUTING DEVICE FOR APPLICATION TO THE EXECUTION OF A NUMERICAL SIMULATION SOFTWARE PROGRAM

A multiprocessor parallel computing device for application to the execution of a numerical simulation software program which includes an external computer, a main processor, a plurality of sub processors, and a DMA controller, and controlled to set up a parallel computing architecture in FDTD (finite difference time domain) and, which divides the computational domain into a plurality of equal cells, then distributes the values of the functions of the three components E.sub.x, E.sub.y, E.sub.z, H.sub.x, H.sub.y, H.sub.z of the variables E and H of the domain to a plurality of sub processors thereof for computation so as to shorten FDTD computer simulation time.
