PURPOSE:To prevent a throughput from becoming worse by sending the job of a class, until the multiplicity of which reaches to the multiplicity set by every job class queue classified by scales to a job executing part, and setting the multiplicity at a larger number for a smaller scale of job. CONSTITUTION:The scale of a thrown-in job 11 is decided from the scheduled time to use a CPU in an executing job administration language at a scale deciding part 12, and the job is registered to either of a large class of queue 13, a medium class of queue 14, or a small class of queue 15 corresponding to the scale of the job. Each of a large class of execution deciding part 16, a medium class of execution deciding part 17, and a small class of execution deciding part 18 sends the job until the multiplicity of the job reaches to the one set for the class to a job executing part 19. In such a case, the multiplicity set for the large class of job is smaller, and for the class medium, larger than that set for the large class of job, and for the small, larger than the medium class. The job in the job executing part 19 is executed under a multiprogramming circumstance. |
