PROBLEM TO BE SOLVED: To prevent a job from going down and to moothly use CPU resources by guaranteeing the allocation time of a CPU to respective jobs without changing the execution priority of these jobs. SOLUTION: A CPU allocation guarantee control part 12 counts CPU tirne used for a job within unit time, and when a job guaranteed at its CPU allocation does not use the CPU more than fixed time, a CPU schedular 15 preferentially allocates the CPU to the job independently of the execution priority of jobs. The preferential allocation of the CPU is appliced also to a job securing a shared resource. Even in an environment that a job having higher execution priority occupies the CPU, rninimum necessary CPU allocation is applied to respective jobs.
