Abstract: Disclosed is a system for supporting creation of a system plan to change a configuration of a power system including a power transmission system and a power distribution system. The system stores information on a configuration of the power transmission system and information on a configuration and a load of the power distribution system. The system determines, based on the information on the configuration and the load of the power distribution system, a load accommodation capacity between power distribution substations which indicates a power supply capacity allowed to be compensated for between the power distribution substations through a configuration change of the power distribution system. The system creates a system plan proposal including a change in system configuration of the power transmission system and the power distribution system based on the load accommodation capacity. The system outputs information on the system plan proposal to an output device.

Abstract: The purpose of the present invention is, in a file storage, to shorten an access response time to shared data. When a file storage apparatus receives a command for a specific manipulation of a file system, a specific apparatus determines, based on a state of the file system and a manipulation history, whether or not an unapplied manipulation affects a target of the specific manipulation, the unapplied manipulation being a manipulation which has been previously executed by another file storage apparatus among a plurality of file storage apparatuses and which has not been applied to the file system. When it is determined that the unapplied manipulation affects the target of the specific manipulation, the file storage apparatus applies the unapplied manipulation to the file system, executes the specific manipulation on the file system, and transmits, to a cloud storage apparatus, manipulation information which represents the specific manipulation.

Abstract: A computer capable of managing reference relationships between data executes access of first and second storage regions in which stored data can be altered and a third storage region in which stored data cannot be altered. The computer sets specification data in the first storage region for accessing data stored in the second and third storage regions, and shifts data having a reference relationship with the specification data from among the data stored in the third storage region to the second storage region. If the accessing occurs while the shifting is being carried out and the data has already been shifted to the second storage region, the reference information for the specification data is amended to the shifted location of the data, and all of the references to data in the third storage region that are referenced by the specification data are amended, thereby releasing the third storage region.

Abstract: A computer manages memory by dividing the memory into at least a first storage area which stores generated data, and a closable region made of at least one second storage area and at least one third storage area. The second storage area constitutes a destination to which the data stored in the first storage area is to be moved. Data is moved from the first storage area to the second storage area; and the second storage area to which the data has been moved is changed to the third storage area. An update to the data stored in the third storage area is detected and the data of which the update has been detected is moved to a closable region other than the third storage area.
