Publication number: 20150355941Abstract: An information processing device includes arithmetic processing devices, a cooling device, and a job assignment device. Each of the arithmetic processing devices is configured to perform a job. The cooling device is connected to the arithmetic processing devices. The cooling device includes a circulation unit, a cooling unit, and an adjustment unit. The circulation unit is configured to circulate refrigerant through a supply route. The refrigerant absorbs heat generated by the arithmetic processing devices. The cooling unit is configured to cool the refrigerant circulated by the circulation unit. The adjustment unit is configured to adjust, in response to a temperature of the refrigerant, a cooling capacity of the cooling unit to cool the refrigerant. The job assignment device includes a processor configured to control, on the basis of cooling capacity information indicating the cooling capacity, job charging to the arithmetic processing devices.Type: ApplicationFiled: April 10, 2015Publication date: December 10, 2015Applicant: Fujitsu LimitedInventor: Jumpei KUBOTA
