Abstract
In submitting each job in a parallel processing system provided with a plurality of processors, execution conditions such as a requested minimum processor number, an upper limit used processor number and a requested execution time are designated for each job and the judgement of whether or not processors equal in number to the requested minimum processor number required by a leading one of execution waiting jobs are in idle states is made for the leading job by use of a table for managing the status of utilization of processors for each job executed and the number of idle processors, a table for managing processors occupied or used by each operating job and a lapse time and a table for managing the execution conditions of each execution waiting job. When idle processors to be assigned are lacking, information in the above tables is used to judge whether a wait until processors corresponding to a number required by that job become idle states is taken without activating a subsequent job or the subsequent job should be activated ahead.
