Method of optimizing an MPI procedure by altering to a procedure other than the invoked MPI procedure portion or by altering the execution sequence

摘要

A method is disclosed for optimizing an MPI procedure by altering to a procedure other than the MPI procedure invocation portion or by altering the execution sequence. In this method of optimizing a program that uses MPI during compiling, optimization of an MPI procedure is realized by detecting an MPI procedure invocation portion within a received source program, and then altering the MPI procedure invocation portion to a procedure other than the detected MPI procedure invocation portion or by altering the execution sequence.
