Abstract: An information processing apparatus includes a memory and a processor coupled to the memory. The processor is configured to: determine whether or not a difference between a total of power consumption values of physical or virtual computers and a preset upper-limit value satisfies a certain condition; select, in ascending order of priorities stored in a first storage and set based on details of processing executed by the computers, any of the computers as a target whose power consumption is to be reduced, when the difference satisfies the certain condition; and switch the computer selected to a state in which the power consumption is reduced.

Abstract: Disclosed is an information processing device provided with: a plurality of processing units each having a TLB (Translation Lookaside Buffer); a means for acquiring a designation of a processing unit, from among the plurality of processing units, where TLB information is to be collected, and for acquiring a designation of the timing at which the TLB information is to be collected; and a means for collecting the TLB information from the designated processing unit at the designated timing.

Abstract: An information processing apparatus running multiple virtual machines includes a correspondence information storage section configured to store correspondence information between a virtual address and a physical address, the correspondence information being used by a second virtual machine when executing a procedure relevant to a first virtual machine; a correspondence information processing section configured to invalidate the correspondence information in response to an occurrence of a panic in the first virtual machine; and a preservation section configured to preserve content of a memory area allocated to the second virtual machine into a storage device.
