AN ARCHITECTURE OF A PARALLEL GRID MULTIPROCESSOR

An architecture is described of a specialized PGM (Parallel Grid Multi processor) supercomputer directed toward efficient solution of large s cale numerical problems by grid methods for partial differential equat ions of different types. The project is based on immediate mapping of the structure of computations and data streams characteristic for grid methods into the hardware architecture. The organization of two impor tant PGM subsystems is described, namely, the distributed interconnect ion network, and the set of parallel functional modules.
