摘要： A computer utilizes correlation matrix data including a value indicating correlation between indicators and comprises a graph process unit that includes a control factor calculation unit configured to calculate a control factor for generating compressed graph data based on a constraint condition on a process; and a graph generation unit configured to generate graph data from the correlation matrix data by using the control factor. The control factor calculation unit obtains a target process time as the constraint condition; calculates a maximum of a number of edges to be included in the graph data; calculates a threshold for extracting the elements converted from the correlation matrix data to the graph data based on the maximum of the number of edges; and outputs the threshold as the control factor. The graph generation unit extracts the elements from the correlation matrix data based on the threshold, and generates the graph data.

摘要： An information processing system includes a optimal-load arrangement means containing a load analysis means, a load distribution means, and program information. The load-computation execution means contains a hardware processing means and a software computation means. The program information includes resource information and information pertaining to data to be processed and the content of the processing to be performed thereon. The load analysis means has the ability to perform community assignment in which, of the data to be processed, data in regions having heavy loads and communication volumes that can be reduced is assigned to a hardware community and data in other regions is assigned to a software community. The load distribution means divides up the data to be processed such that the data assigned to the hardware community is processed by the hardware processing means and the data assigned to the software community is processed by the software computation means.

摘要： An optimization system has a plurality of nodes, each including: a calculation processing unit that calculates an optimum value of a determination variable representing a parameter that controls the nodes by using the ADMM; and a function value calculation unit that receives an input of a value of the determination variable and calculates the value of the objective function based on a calculation model constructed by a learning processing. An arbitrary value of the determination variable is input to the function value calculation unit, and the calculation processing unit substitutes the value of the objective function calculated by the function value calculation unit and the arbitrary value of the determination variable into a second optimization problem by dual transformation of the first optimization problem, thereby repeatedly executing a processing of calculating a value of the dual variable until the value of the dual variable satisfies a predetermined condition.
