METHOD FOR INTERFACING MPICH CHANNEL USING CHORUS IPC

摘要

PURPOSE: An MPICH interface method is provided to be capable of drawing a parallel computer application program easily. CONSTITUTION: An MPI library(11) consists of 125 routines and comprises an operation routine and an execution time structure for charging a point-to-point communication for operating a group communication, a group circumstance management, a topology operation and a data type operation. An abstract device interface(12) consists of a core message passing routine, a core service routine and an expansion routine. A channel interface(13) consists of a channel communication routine and a plurality of functions. Since each lower layer is not affected by an upper layer, a selective access method(5) is that a lower layer is realized using chorus IPC(4).
