Abstract: A job assigning apparatus which is connected to a plurality of job processors and assigns the job to any of the job processors includes: an accepting section that accepts the job; an assigning section that selects a job processor having the least number of processes and assigns the accepted job to the selected job processor; a managing section that manages each of the job processors and the number of processes of the job assigned to each of the job processors by the assigning section in association with each other; an adding section that adds the number of processes of the jobs assigned by the assigning section to the number of processes managed by the managing section; and a notifying section that notifies another job assigning apparatus for assigning a job to a job processor of the number of processes of the job assigned by the assigning section.

Abstract: A parallel-process execution method which increases the throughput of the entire system in an environment in which turnaround times of parallel programs are guaranteed. Parallel processes generated from parallel programs are assigned to time periods in processing periods of processors, where the time periods correspond to processor allocation ratios respectively preset for the parallel programs. Then, it is determined whether or not parallel processes generated from each parallel program can be assigned to idle time periods (which are included in the processing periods and to which no process has been assigned yet) of the processors so that the parallel processes generated from each parallel program can operate in parallel in the idle time periods. When yes is determined, the parallel processes are additionally assigned to the idle time periods. Finally, the processors execute the parallel processes respectively assigned to the processing periods of the processors.
