An information processing apparatus that mounts a first and second system boards SB#and SB#includes a virtualization control unit that operates a virtual machine for virtualizing hardware resources. The SB#includes a memory that stores a command line, resource information, and management information. The SB#includes a memory that stores a command line and resource information. The command line is executed by the virtualization control unit. The resource information is data used by each system board from among data used when the virtualization control unit operates. The management information is data commonly shared by each system board and used by the virtualization control unit. A command line and resource information are used when the virtualization control unit operates and information on the hardware resources included in the corresponding SB. Each SB executes the command line and refers to the information stored in the memory in SBs.

Program redundancy among virtual machines and global management information and local resource information arrangement

An information processing device, including: a memory; a processing unit which operates a virtual machine, an operating system which is executed on the virtual machine, and a hypervisor which controls the virtual machine; and a control unit which controls a system including the memory and the processor. The processing unit stops the operating system when detecting an error of the hypervisor, notifies the control unit of a first memory area used by the hypervisor, stops the hypervisor, changes a memory area used by the hypervisor into a second memory area different from the first memory area notified by the control unit, starts the hypervisor using the second memory area as an available area, starts the operating system, and reads data in the first memory area, and writes the data to a file as a dump file of the hypervisor.

Information processing device with memory dump function, memory dump method, and recording medium

In an information processing apparatus, a control unit includes a first clock device for providing the time of day. A physical domain includes a second clock device, and implements a logical domain that functions as a virtual information processing apparatus. The control unit controls a first time-of-day difference between the time of day of the first clock device and that of the second clock device. The physical domain controls a second time-of-day difference between the time of day of the second clock device and that of the logical domain. In the information processing apparatus, the time of day on the logical domain is controlled based on the first and second time-of-day differences.

Information processing apparatus and time-of-day control method

An information processing apparatus that executes an operating system, the apparatus including a panic process unit configured to stop the operating system when the operating system has detected an error, a mapping process unit configured to assign, to the operating system stopped by the panic process unit, a second memory area which is other than a first memory area being used by a kernel of the operating system before stop or by a hypervisor that controls the operating system before stop of the operating system, a reactivation process unit configured to reactivate the operating system by using the second memory area as a usage area, and a memory dump process unit configured to read data in the first memory area, and to write the data to a dump file after the operating system is reactivated.

Information processing apparatus having memory dump function, memory dump method, and recording medium

An information processing apparatus having a storage that stores identification information for identifying an event occurring in a forefront module and completion information for identifying a module having completed the corresponding process, an identifier that identifies an event that any module has not completed the process based on the completion information, an instructor that provides the identification information related to the event identified by the identifier to the forefront module, and instructs the forefront module to execute the process related to the identified event. Each of the modules operates as a determiner that reads the completion information corresponding to the received identification information, and determines whether to skip the process of its own module, and a deliverer that delivers, the identification information to the immediately succeeding module in a case where the determiner determines to skip the process of its own module.

Information processing apparatus

An information obtaining unit provided inside a system controller obtains operation states of processing units and processing units respectively of cabinets, calculates an average utilization of CPUs of the processing units, and determines whether or not any processing unit can be disconnected. When a hardware resource can be disconnected as a result of the determination, an electric power control determining unit calculates possible combinations of hardware resources to be disconnected and performs a disconnection by a cabinet unit when there is a combination enabling a disconnection by a cabinet unit.
