ABSTRACT:
The system for executing processes in parallel in a multiprocessor system having plural instruction processors performs parallel processing by converting a source program written in a high-level language into an object module, creating parallel processes for the processing of the parallel-executable parallelling object segment, and executing the parallel processes on the plural instruction processors. In the object module, a run cost value is set for giving a standard of a run time for the parallel-executable parallelling object segment, and the number of the parallel processes to be created is determined in accordance with the run cost value immediately prior to the execution of the parallel processes. Then, the parallel processes are created in the number determined to be created, and the parallel processing is performed by the execution of the parallel processes.
