  • Publication number: 20240161594
    Abstract: An information notification device is configured to: acquire apparatus information on an apparatus; determine an action for the apparatus based on the apparatus information; determine an executor who is to perform the determined action from among multiple users; determine a notification target person to be notified that the executor is to perform the action with reference to relationship information indicating a relationship among the multiple users; and notify the determined notification target person of notification information indicating that the executor is to perform the action.

  • Patent number: 11980107
    Abstract: A quantum computing system including plural base configurations each configured including a first quantum bit group configured from first quantum bits arranged so as to form a single column without mutual coupling, a second quantum bit group configured from second quantum bits arranged so as to form a single column with adjacent ones of the second quantum bits coupled together and each of the second quantum bits coupled to the first quantum bit that is arranged in a same row, and a third quantum bit coupled to all of the second quantum bits. The plural base configurations are arranged so as to form a single column with the third quantum bits in adjacent ones of the base configurations coupled together. In a quantum computing circuit configuration, a two-dimensional cluster state or a three-dimensional cluster state is accordingly realized with two-dimensional control wiring, or surface code is accordingly realized with a pseudo two-dimensional superconducting circuit.

  • Patent number: 7162580
    Abstract: A method for remotely copying volumes is disclosed. An identifier of a first disk subsystem of a first volume is obtained from a volume pair list. The first volume is a copy source or a copy destination of a volume pair. Route information including the identifier of the first disk subsystem is searched from a route list, which includes route information for determining an identifier of a second disk subsystem that relays a transmitting route of a command to the first disk subsystem and for determining an identifier of a third disk subsystem connected to a host computer. The identifier of the third disk subsystem indicated by the route information is obtained. A remote copy command of the first volume is issued to the third disk subsystem corresponding to the obtained identifier.

  • Publication number: 20050132156
    Abstract: A volume remote-copy control method is disclosed to automatically define and control a transmitting route of a remote command for remote copy control. An identifier of a first disk subsystem of a first volume is obtained from a volume pair list. The first volume is a copy source or a copy destination of a volume pair as a remote copy target in disk subsystems to a host computer connected to at least one of the disk subsystems. The volume pair list registers the identifier of the first volume and the identifier of the first disk subsystem to which the first volume belongs. Next, route information including the identifier of the first disk subsystem is searched from a route list. The roue list includes the route information for registering information for determining an identifier of a second disk subsystem for relay as a transmitting route of a command to the first disk subsystem and an identifier of a third disk subsystem connected to the host computer among the second disk subsystems.
