A METHOD OF, APPARATUS FOR, AND RECORDING MEDIUM STORING A PROGRAM FOR, PARALLELIZING A PROGRAM CONTAINING AN ARRAY DESIGNATED TO UNDERGO INDIRECT AND IRREGULAR DIVISION.

A method of, apparatus for and computer-readable medium for obtaining a program for a distributed memory-type parallel computer by dividing data for a program written for a serial processing computer. The method comprises changing a declaration of an array to be subjected to indirect or irregular division which is designated by the mapping array in the program into a declaration of an allocation array; inserting statements to declare the allocation array for converting subscripts and to calculate the size of the divided array during processing, and inserting a statement to preserve or to release an area for divided arrays corresponding to the calculated length of arrays to be divided and subscript conversion arrays during processing.
