Abstract: A calculation capability of grid computing using a calculation resource mounted on a moving body is promptly provided to a client. A management server configures a candidate of a moving body group forming a grid for executing grid computing as a grid candidate with reference to resource information and moving body information stored in a memory. The calculation resource information including a temporal change in a calculation capability is estimated for the configured grid candidate with reference to the resource information and the moving body information, and the estimated calculation resource information is stored in the memory together with data specifying a moving body configuring the grid candidate.

Abstract: An automotive arithmetic system includes a main arithmetic device that determines a target motion of a motor vehicle so that the motor vehicle travel on a route generated based on a vehicle external environment estimated using deep learning based on an output from a vehicle external information acquisition device; and a backup arithmetic device that determines a backup target motion for causing the motor vehicle to travel on a travel route which is generated based on the output from the vehicle external information acquisition device and which the traveling motor vehicle takes until the motor vehicle stops at a stop position that satisfies a preset criterion. The automotive arithmetic system outputs a backup control signal to actuators in preference to a control signal when the main arithmetic device fails.

Abstract: In prediction processing, the controller predicts a temporal change in a calculation capability available in grid computing processing of each of a plurality of arithmetic devices. In the request processing, in a case where the calculation capability of the arithmetic device predicted to be available in the grid computing processing on the basis of a result of the prediction processing is insufficient, the controller presents, to a user who owns another arithmetic device except for the arithmetic device predicted to be available in the grid computing processing among the plurality of arithmetic devices, request information for prompting provision of the calculation capability of the another arithmetic device to the grid computing processing.
