A power source control executed by a processor includes setting a plurality of period candidates indicating candidates of a predetermined period; calculating, for each of a plurality of nodes, an average interval of idle periods in which a procedure is not executed for each of the plurality of period candidates, based on operation record information indicating history of procedures; calculating an amount of reduction of power consumption with respect to each of the plurality of period candidates based on the calculated average interval and an amount of power consumption in the idle period; selecting a period that is allocated to each of the plurality of nodes from among the plurality of period candidates based on the calculated amount of reduction; and executing, for each of the plurality of nodes, control to set the power source to an off state when the idle period becomes the selected period or more.

Power source control method, power source control apparatus, and storage medium

A process allocation apparatus includes an evaluation value calculating unit, an internode total communication traffic calculating unit, and a correction evaluation value calculating unit. The evaluation value calculating unit calculates an evaluation value of process allocation in accordance with a hop count and inter-process communication traffic from a communication source node to which a process used as a communication source is allocated to a communication destination node to which a process used as a communication destination is allocated. The internode total communication traffic calculating unit specifies a communication route from the communication source node to the communication destination node and calculates internode total communication traffic indicating that the communication traffic between nodes on the specified communication route. The correction evaluation value calculating unit calculates a correction evaluation value used for the correction in accordance with the calculated evaluation value of the process allocation and the calculated internode total communication traffic.
