Abstract: An object of the invention is to quickly and appropriately adjust performance of a storage system. Provided is a storage management system including: a storage system including a plurality of storage nodes; and a management device. The storage node includes a storage device and an instance to which a resource is virtually allocated and that controls access to the storage device. The storage management system further includes an instance management node configured to manage the instance of the storage node. The management device is configured to determine whether a configuration of the resource allocated to the instance of the storage node needs to be changed, and cause the instance management node to change the configuration of the resource allocated to the instance when the configuration of the resource needs to be changed.

Abstract: In a retrieval method executed by a retrieval device in which a storage unit holds enterprise information, classification code information, and item keyword information corresponding to an enterprise and an item of a particle supplied by the enterprise, at least one of a keyword indicative of a business of a first enterprise or a classification code of an item registered by the first enterprise is input. At least one item keyword is extracted corresponding to at least one of an enterprise similar to the first enterprise or an item similar to the item registered by the first enterprise, based on at least one of the keyword indicating the business of the first enterprise or the classification code of the item registered by the first enterprise, by referring to the enterprise information, the classification code information, and the item keyword information. Then, the extracted at least one item keyword is output.

Abstract: It is possible to implement a control device for a quantum bit array having high practical utility, that can efficiently hold, with a small number of bits, control parameters necessary for quantum operation in the quantum bit array in which a plurality of quantum bits are arranged. There is provided a control device that controls quantum operation in a quantum bit array in which a plurality of quantum bits are arranged one-dimensionally or two-dimensionally. The control device includes a command memory that stores a plurality of control commands and a parameter memory that stores part or all of control parameters accompanying the control commands. A command format of the control commands includes one or more parameter specifying fields to specify either an immediate value of a control parameter or reference to the control parameter stored in the parameter memory.

Abstract: A backup-source storage system extracts, as a pattern, forwarding target data to a backup-destination storage system among data written to a storage apparatus through a volume. The backup-source storage system determines whether the extracted pattern matches with a registered pattern in the backup-source storage system. When a result of the determination is false, the backup-source storage system registers the extracted pattern and forwards the forwarding target data to the backup-destination storage system. When the result of the determination is true, the backup-source storage system does not forward the forwarding target data.

Abstract: Information about validity of recommendation information is presented to a user in a repair recommendation system that includes: a repair recommendation engine unit that is configured to infer, using a learning model that receives failure information about a device and outputs a handling content recommended for handling a failure, recommendation information including a plurality of the handling contents corresponding to the received failure information and a confidence level of each piece of handling information. An input and output processing unit is configured to classify, based on the confidence level, the handling content into any one of a plurality of determination groups provided according to a degree of the confidence level, specify a case resolution rate associated in advance with the determination group in which the handling content is classified, and output, as validity information about the recommendation information, information about magnitude of the specified case resolution rate.

Abstract: A computer system for searching for a candidate for an environment in which an object is to be deployed, the computer system is coupled to a plurality of infrastructure systems each of which provides the environment. The computer system receives a search request including an environmental requirement being a condition required for the environment in which the object is to be deployed and a constraint being a condition to be complied with in deployment of the object; executes first environment search processing for searching for the environment that satisfies the constraint and the environmental requirement; changes the environmental requirement in a case where the environment in which the object is deployable does not exist; and executes second environment search processing for searching for the environment that satisfies the constraint and the changed environmental requirement.

Abstract: A storage device stores a state transition model in which a first state transition probability (state transition probability function τ), which indicates the probability that a prediction subject will transition from a first state s to a second state s′ after a first time (Δt) has elapsed, is expressed by a linear combination of weighted basis functions (model storage unit). A computation device calculates a second state transition probability (attenuation-type state transition probability function D), which indicates the probability that the prediction subject will transition from the first state s to the second state s′ after a second time (Δt×∞) has elapsed, by means of a product-sum computation of a weight matrix ∇ representing a matrix the elements of which are the respective weights of the weighted basis functions (future state prediction computation unit).
