Abstract: A management device is used in a grid computing system, wherein a computational job constitutes a part of a project to be implemented by a client. The management device is configured to: store the content of the project, and a compensation rate set for the computational job of the project; acquire a computational amount of computational processing executed for the computational job by a computing device; calculate a first compensation value of a first compensation to be given to the user, according to the computational amount by the computing device; and acquire the degree of progress of the project, and when it is determined, based on the acquired degree of progress, that the project has been completed, calculate a second compensation value of a second compensation to be given to the user, according to the compensation rate.

Abstract: Grid computing processing is managed considering rate of amount of renewable energy-derived electric power in amount of electric power used for computation by computing device of vehicles, thereby contributing to utilization of renewable energy. Management server manages grid computing processing of causing computing devices mounted on a plurality of vehicles to process job data provided from client server. Controller of the management server acquires overall renewable energy rate information indicative of the rate of the amount of renewable energy-derived electric power in the amount of electric power consumption used for computation of the job data by all computing devices assigned to the job data, based on the amount of computations for a part of the job data to be processed by each of the computing devices and renewable energy rate information of each of the computing devices, and transmits the overall renewable energy rate information to the client server.

Abstract: A management device used in a grid computing system is configured to execute compensation calculation processing of calculating a first compensation and a second compensation with respect to execution of a computational job by a computing device of a user, and stores evaluation values each set for a respective one of a plurality of computational jobs, wherein the compensation calculation processing includes: a first processing of calculating a first compensation value of the first compensation according to a computational amount of computational processing; and second processing of calculating and storing a second compensation value of the second compensation according to a relevant one of the evaluation values, wherein management device is configured to, in the first processing, calculate the first compensation value to have a larger value, as a cumulative value of the second compensation values which have been previously stored has a larger value.

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.
