Abstract: Comfortability can be visually displayed for a user in real time while power consumption is controlled. A display device communicates to/from a power control device for controlling power of a power consumption system including a plurality of apparatus. An input unit specifies a desired set value for each of the plurality of apparatus or a power consumption system including the plurality of apparatus. A display unit displays a display content corresponding to a degree of divergence in real time when an amount of upper limit power for the entire power consumption system including the plurality of apparatus is set, the degree of divergence being calculated based on a comparison between an actual set value for the plurality of apparatus having an amount of power being subjected to demand control based on an evaluation function set for the plurality of apparatus and the desired set value specified through the input unit.

Abstract: To increase the reliability of power supply control of a server group and reduce the power consumption of the server group.

Abstract: A distributed object management system includes: a completion information management portion which stores a relay state of the object server and which manages information of the object which should be transmitted again when the transmission to the object server is resumed; and a relay control portion which requests other object server to temporally exclude the object server that has transmitted the suspension request from a copying operation of the object and which, if the resume request is received from the object server that has transmitted the suspension request, requests said other object server to include the object server that has transmitted the resume request in the copying operation of the object again.

Abstract: A distributed storage system, includes: a first data storage unit that holds data in a first data structure; a second data storage unit that holds the data in a second data structure different from the first data structure; an update information holding unit that holds an update information item(s) indicating update content of the data, and if a predetermined update condition is satisfied, applies the update information item(s) to the second data storage unit and reflects the update content in the second data storage unit; an update state monitoring unit that monitors the update information item(s) held by the update information holding unit and extracts as an update state an application status of the update information item(s) to the second data storage unit; and an update condition change unit that changes the predetermined update condition based on a change command for changing the predetermined update condition, the change command being determined in accordance with the update state.

Abstract: When a specific message flow is formed among a plurality of processes, process insertion and removal are facilitated. A topic management device includes a correspondence table storage unit which stores correspondence data which associates an abstract topic which is a topic described in a program with a real topic which is a topic for controlling message transmission and reception for each process to be executed by a processing device, and a topic management service control unit which transmits the correspondence data to the processing device. The processing device includes a topic lookup unit which receives the correspondence data from the topic management device, and a message processing unit which transmits and receives a message using the real topic corresponding to the abstract topic described in the program of a process to be executed based on the correspondence data received in the topic lookup unit.

Abstract: Provided is a data supply apparatus including a transmission device that sends data to another data supply apparatus; a reception device that receives data from another data supply apparatus; a data storing device that stores data in a storage device; and a data storage determination device that determines whether or not the received data should be stored in the storage device, based on a predetermined supply probability. In a typical example, the reception device receives the data to which supply probability information which indicates the supply probability has been appended; and the data storage determination device determines whether or not the received data should be stored in the storage device, based on the supply probability indicated by the supply probability information.

Abstract: A system includes a processing history recording means that records history information of information processing performed by an information processing means on data, a plurality of information storing means that store information in mutually different information storage formats, and an information storage format control means that controls to changes an information storage format of data, on the basis of a history of information processing performed on the data.
