PROGRAM FOR AUTOMATICALLY GENERATING MULTIPLE REPETITION PROCESSING ULTRA-PARALLELIZED SOURCE CODE, AND APPARATUS AND METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To automatically convert a non-parallelized source code having a multiple loop structure into a parallelized source code executable by a plurality of processors. SOLUTION: In this program P for automatically generating a multiple repetition processing ultra-parallelized source code for automatically generating a parallelized source code executable in parallel by an m (m is an integer which is not less than 2) pieces of processors from a non-parallelized source code SC including an n (n is an integer which is not less than 2)-fold nested loop, the initial value formula of each of the n-fold loops of the non-parallelized source code SC is rewritten to an initial value formula Sj expressed by the following formula by using m pieces of continuous integers iak (k=0,..., m-1) starting with 0 uniquely identifying each processor which are applied to m pieces of processors and an incremental valueδj decided for each loop j (j=1,..., n), and the n-fold loop structural part is converted into the structure whose processing can be shared by the m pieces of processors by using the rewritten initial value formula and the incremental valueδj by the function of a CPU 2.
