  • Patent number: 10896103
    Abstract: A first system receives values with identifiers of the values from one or more clients. The first system enters the values sequentially into a first data store. The first system associates each of the values with a sequence ID indicating a position in entry sequence of the values into the first data store. The first system transmits a first identifier of a first value and a first sequence ID associated with the first value to a second system. The first system transmits the first sequence ID and the first value to the second system after transmitting the first identifier and the first sequence ID. The second system holds the first identifier and the first sequence ID transmitted from the first system in a first queue. The second system enters the first value received after the first identifier from the first system into a second data store.

  • Publication number: 20200320409
    Abstract: A model creation supporting system executes: learning processing to create an inference model by performing machine learning on pieces of training data so as to specify a feature of each piece of the data, the inference model being designed to infer a label to be set to a piece of input data based on a feature of the piece of input data; and evaluation processing to determine validity of inference of the label in accordance with the inference model by determining a similarity between a feature of a given piece of data specified by inputting the given piece of data to the created inference model and the feature of one of the pieces of training data specified by the machine learning, and to output information indicating a content of the determination.

  • Publication number: 20190310982
    Abstract: A technology is disclosed that makes it possible even for an analyst, who has poor knowledge relating to field data, to select and use analysis data in analysis. A data catalog automatic generation system that generates a catalog tag to be used to select analysis data from collected field data is configured such that, based on a set classification rule input, a relationship between an objective variable as an analysis perspective relating to field data and an explanatory variable or a causal relationship between a plurality of the explanatory variables is extracted, and based on a result of the extraction, a catalog tag of the objective variable and a catalog tag of the explanatory function are specified and attached.

  • Patent number: 10298715
    Abstract: The present invention relates to a distributed processing system having a master node and a plurality of worker nodes. Each worker node has an assigned identifier. A worker node caches in its own memory first output data, which is the result of the execution of a first task, and copies said first output data to another worker node. The master node selects, on the basis of the identifier information of the first worker node, a worker node to which to assign a second task, wherein the first output data is used as input data.

  • Patent number: 9811465
    Abstract: A plurality of nodes includes an I/O (Input/Output) node and a plurality of computation nodes. Each computation node sends an I/O request to the I/O node. The I/O node includes a first storage device which stores data to be written or read according to the I/O request and a first memory device on which a first cache area is based to temporarily store the data written in the first storage device or read from the first storage device. The computation node includes a second memory device on which the second cache area is based to temporarily store the data according to the I/O request. At least one of the I/O node and the computation node stores management information which contains information on a physical storage area in the cache area of the other one of the I/O node and the computation node, and information on a virtual storage area which is associated with the physical storage area and has a part of its own cache area.

  • Patent number: 9632718
    Abstract: A converged system and migration method capable of preventing system performance degradation with respect to data transfer is proposed. A first calculation node continues executing I/O processing in response to an I/O request from an application; and, upon execution of the I/O processing, the first calculation node issues an I/O processing event notice indicating a transfer status of data on which the I/O processing has been executed. When receiving a migration command from a migration management unit, a second calculation node judges whether or not data stored in a first I/O node is data which should be transferred, based on the I/O processing event notice; and then transfers the data, which should be transferred, to a third calculation node.

  • Patent number: 9600185
    Abstract: In a computer, a logical partition for calculation in which an OS and an application operate and a logical partition for storage for providing a storage function are constructed. In the logical partition for calculation, a device corresponding to a storage device is provided, while the logical partition for storage provides a volume. A memory space that can be shared by the both logical partitions is prepared, and management information describing a sorting destination or a sorting method of an I/O request issued by an application is provided in the memory. If the logical partition for calculation receives an I/O request from the application, the partition refers to the management information and sorts the I/O request to the storage device or the logical partition for storage. The logical partition for storage processes the received I/O request by the storage function and transmits the result to the storage device.

  • Publication number: 20150363128
    Abstract: A management system manages at least a storage system. The management system decides two or more logical storage devices configuring a logical volume to be provided to an application. The management system decides two or more MPs that undertake processes on the two or more logical storage devices, respectively. The management system allocates the decided two or more MPs to the decided two or more logical storage devices such that one MP is allocated to one logical storage device.
