  • Publication number: 20210011949
    Abstract: A data analysis device is configured to include an arithmetic operation device that determines whether or not each point data in the point data group of the existing clusters is a core of the cluster using a predetermined algorithm and calculates a predetermined re-verification determination data, recalculates an initial condition value of the clustering based on the re-verification determination data, specifies re-verification point data which is the point data that becomes no longer the core or becomes a new core by adding the point data, from the point data group to which the addition was made, based on the updated initial condition value obtained by the recalculation, and performs predetermined clustering processing in accordance with the re-verification point data.

  • Patent number: 10715553
    Abstract: A federated gateway bridges service definition formatting differences between a first and a second independent enterprise information technology (IT) management domain. A service request is received within the federated gateway from a service consumer application executing within the first independent enterprise IT management domain to a remote service provider application in the second independent enterprise IT management domain. The federated gateway dynamically performs real-time service call translation during transmission of the service request from a local service definition format to a remote service definition format defined respectively within the first and second independent enterprise IT management domains.

  • Publication number: 20190384272
    Abstract: Input data, output data having a plurality of output parameters obtained by analyzing the input data, and a plurality of associations between the input data and the output data are stored. A division condition for dividing an output data distribution in which the output data is plotted for two axes corresponding to two parameters among the plurality of output parameters is extracted, the output data distribution is divided according to the division condition, and output data of the divided output data distribution is derived as first and second output data distribution rules corresponding to the two axes. First and second output data distribution region candidates are calculated by applying the first and second output data distribution rules to new input data, and an output data distribution region of the new input data is estimated by combining the first and second output data distribution region candidates with each other.

  • Patent number: 9317519
    Abstract: A storage system 103 carries out first and second de-duplication processes in response to receiving a write request from a client. First, a determination is made as to whether a write target data item overlaps with any of the stored data items of a part of a stored data item group, which is a user data item group stored in a storage device 209, and if so, the write target data item is prevented from being stored in the storage device. Second, a determination is made as to whether a target stored data item, which is not finished being evaluated as to whether it overlaps with the stored data item in the first de-duplication process, overlaps with another stored data item, and if so, the target stored data item or the same data item overlapping with the target stored data item is deleted from the storage device 209.

  • Patent number: 9251163
    Abstract: In a computer system according to an embodiment of the present invention, a first slave server includes copy management information associating a master file system identifier with an identifier of a slave server including a copy of the master file system identified by the master file system identifier. The first slave server acquires a copy of a part of a master file system. The copy includes a stub-state object (file or directory). The first slave server searches the copy management information for a slave server to be queried regarding information for materializing the stub-state object. If the slave server to be queried includes the information for materialization, the first slave server materializes the stub-state object using the information for materialization acquired from the queried slave server.

  • Publication number: 20160006829
    Abstract: A second storage unit stores a first piece of data and second pieces of data. Each of first storage units holds configuration information indicating association between the first piece of data and the second pieces of data associated by first computers. Each of the first computers receives a second piece of data and register information of the received second piece of data in the configuration information, instructs a second computer to store the received second piece of data in association with the first piece of data, and identifies a second piece of data to be acquired from the second computer based on the configuration information in acquiring the second piece of data. The second computer, in accordance with instructions from the first computers, stores the second pieces of data in the second storage unit in association with the first piece of data.
