摘要： Multiple parallel-job scheduling method and apparatus are provided which can improve the utilization of all processors in a system when a plurality of parallel jobs are executed concurrently. A plurality of processors constituting a computer system and each having the equal function are logically categorized into serial processors for executing a serial computing part or a parallel computing part of a parallel job and a parallel processor group consisting of multiple processors for executing the parallel computing part of the parallel job in parallel. In order that the parallel processors are shared by a plurality of parallel jobs, a synchronization range indicator is provided which can control by program whether the parallel processors are available in correspondence to the respective serial processors. In response to a request for using the parallel processors from a serial processor for which the parallel processors are so set as to be available by means of the synchronization range indicator, operation can be carried out without invoking an interrupt.
