Abstract: According to an embodiment, a method includes receiving a query, and selecting one of first objects on the basis of the query and a neural network model. Each of the first objects is associated with one or more pieces of first data in a group of first data stored on a first memory. The method further includes calculating a metric of a distance between the query and one or more pieces of second data. The one or more pieces of second data are one or more pieces of first data associated with a second object. The second object is the one of the first objects having been selected. The method further includes identifying third data on the basis of the metric of the distance. The third data is first data closest to the query in the group of the first data.

Abstract: An organic compound is represented by general formula [1-1]. In general formula [1-1], X is an oxygen atom, a sulfur atom, a selenium atom, or a tellurium atom, and R1 to R18 are each independently selected from the group consisting of a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted amino group, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted silyl group, and a cyano group.

Abstract: The storage system includes a controller and a storage drive accessible from the controller. The controller includes a memory and a processing unit. The memory includes a first cache area in which the writing of data by the storage drive is permitted, and a second cache area in which the writing of data by the storage drive is prohibited. A In the first cache area, the storage of data, by staging-in-advance in response to a read request for a sequential read, by the processing unit is permitted, and the storage of cache data in a dirty state by the processing unit is prohibited. In the second cache area, the storage of the cache data in the dirty state by the processing unit is permitted.

Abstract: Each node constituting a distributed storage system includes one or more controllers. Each controller includes an actual queue group for each drive physically coupled to the controller, and a virtual queue group for each of a plurality of drives. A Drive-IO issued by any controller and received is accumulated in the actual queue group corresponding to an issue destination drive of the Drive-IO after accumulated in the virtual queue group corresponding to the issue destination drive.

Abstract: The present invention continues host access and holds data of a migration source volume as the latest data even when a fault occurs in any of a plurality of access paths. Upon receiving a first write command from a host computer via a first access path, the migration source controller writes first update data to the migration source volume and, upon receiving a second write command from the host computer via a second access path, the migration destination controller transfers second update data to the migration source controller via a storage path and, upon receiving the second update data from the migration destination controller, the migration source controller writes the second update data to the migration source volume.

Abstract: A storage apparatus 10 includes a communication control processor 11 that is a processor configured to control communications with a host apparatus 3, and plurality of main processors 12 each configured to perform an I/O process on a storage drive 171 according to an I/O request received from the host apparatus 3. The storage apparatus 10 manages data to be stored or that has been stored in the storage drive 171 in accordance with the CKD format. The storage apparatus 10 distributes the I/O process to the plurality of main processors 12 in units of the data fields on basis of the operation rates of the respective main processors 12, information on a C field, a K field, and a D field that are data fields forming a record of data targeted by the I/O process and managed in CKD format, and an I/O load indicator being a load indicator of the I/O process currently running on each of the main processors.

Abstract: A route searching apparatus comprises a processing device that searches a guided route along which a vehicle is to be guided from a current vehicle position to a destination and also searches a detour route for detouring a detour segment set over part of the guided route. The processing device extracts guidance-requiring intersections at which the vehicle needs to be guided to follow a course among intersections on the guided route, sets a segment ending at a guidance-requiring intersection close to the current vehicle position among the guidance-requiring intersections as the detour segment, and searches the detour route for detouring the detour segment.
