摘要： A computer system operates a data processing unit that includes a first memory, an accelerator including a second memory, and a storage device. The computer system receives a processing request for data and analyzes the contents of processing included in the processing request and detects a load of the accelerator. An off-load processing unit acquires the analysis results and the load of the accelerator to make the accelerator execute the processing when a predetermined condition is established. The processor executes the received processing when the predetermined condition is not established. The off-load processing unit makes the accelerator secure a storage area in the second memory, makes the storage device transmit the data, and the accelerator executes the processing. The processing execution unit makes the processor secure a storage area in the first memory, makes the storage device transmit the data, and the processor executes the processing.

摘要： A storage apparatus has a plurality of hardware engines which send and receive information to and from a controller, which, on the condition of acquiring a request command from a host, determines identifying information of the request command, executes data I/O processing to the storage device according to the request command when first identifying information has been added to the request command and when second identifying information has been added to the acquired request command, transfers the request command to the hardware engine, acquires the data requested by the hardware engine from the storage device and transfers the acquired data to the hardware engine. The hardware engine acquires and analyzes an add-on command from the host and according to the request command, requests the controller to transfer the data based on the analysis result, and thereafter executes processing to the data transferred by the controller according to the add-on command.

摘要： A work support system is capable of avoiding situations where a worker performs erroneous work. The system includes an identification unit which identifies a target of an inquiry from a worker based on a video acquired by an imaging device, a selection unit which selects determination model information corresponding to each of one or more targets of inquiry identified by the identification unit from a storage unit storing determination model information to be used in a determination model. A determination unit determines whether each of the targets of inquiry is correct by using each of the determination models in which the determination model information, which was selected by the selection unit, corresponding to each of the one or more targets of inquiry identified by the identification unit, has been set in the determination model. An output unit outputs a determination result of the determination unit.

摘要： A highly-reliable work report is prepared while reducing the worker's burdens. A work support system 200 prepares a work report by using information including at least a video collected while conducting work. The work support system 200 includes: a work completion recognition unit 240 that judges a completion of the work from the information collected while conducting the work and recognizes completion time of day of the work; a video extraction unit 250 that extracts a video upon completion of the work from the video, which are collected while conducting the work, with reference to the completion time of day of the work; a work recognition unit 260 that recognizes a work item(s) of the work by using the extracted video upon completion of the work; and a work history generation unit 280 that generates a work history of the work in the work report on the basis of recognition results by the work completion recognition unit 240 and the work recognition unit 260.

摘要： The PLD management system includes a PLD management unit that manages the usage status of each of one or more PLDs. The PLD management unit receives a PLD usage request from a request source module which is one of a plurality of processing modules sharing each of the one or more PLDs. when the PLD management unit receives the usage request, the PLD management unit performs control to prevent two or more processing modules including the request source module from utilizing the same PLD at the same time based on a current usage status of a PLD corresponding to the usage request and content of the usage request.

摘要： A storage unit includes a plurality of storage devices that form a RAID group, that are coupled to the same bus, and that communicate with each other. Each of the plurality of storage devices includes a device controller and a storage medium. The plurality of storage devices store each of data and parities generated on the basis of the data, the data and the parities being included in RAID stripes. A first device controller of a first storage device included in the RAID group transmits, to the plurality of storage devices included in the RAID group other than the first storage device, an instruction to transfer the data and/or the parities included in the RAID stripes and restores the data or the parity corresponding to the first storage device of the RAID stripes on the basis of the transferred data and the transferred parities.

摘要： A data memory device has a command transfer direct memory access (DMA) engine configured to obtain a command that is generated by an external apparatus to give a data transfer instruction from a memory of the external apparatus; obtain specifics of the instruction; store the command in a command buffer; obtain a command number that identifies the command being processed; and activate a transfer list generating DMA engine by transmitting the command number depending on the specifics of the instruction of the command. The transfer list generating DMA engine is configured to: identify, based on the command stored in the command buffer, an address in the memory to be transferred between the external apparatus and the data memory device; and activate the data transfer DMA engine by transmitting the address to the data transfer DMA engine which then transfers the data to/from the memory based on the received address.
