RESOURCE MANAGEMENT DEVICE, RESOURCE MANAGEMENT SYSTEM, RESOURCE MANAGEMENT METHOD, AND RESOURCE MANAGEMENT PROGRAM

摘要

PROBLEM TO BE SOLVED: To dynamically and efficiently adjust allocation ratios of a CPU resource to respective classes in a state of retaining an allocation ratio of the CPU resource to the respective classes as a whole multiprocessor system.;SOLUTION: The resource management device includes: storage means that stores an upper limit of a ratio of allocatable whole processing capacity of a central processing unit for a class to which the processing belongs; measurement means that measures the ratio for each class; execution control means that does not allocate the resource to processing of a class, the measurement value of which reaches the upper limit; and change means that, when a resource use rate of a first class reaches the upper limit in a first central processing unit, changes an upper limit of the first class and an upper limit of a second class selected by a prescribed criterion in the first central processing unit, to values obtained by adding and subtracting a prescribed adjustment value respectively, and changes upper limits of a first and a second class in a second central processing unit selected by a prescribed criterion to values obtained by subtracting and adding the adjustment value respectively.;COPYRIGHT: (C)2014,JPO&INPIT
