Abstract
A distributed system includes: a plurality of ordinary nodes provided with reduced-power states having different times of recovery to a normal operating state; and a management node for assigning a job to an ordinary node for carrying out the job. The management node has: node select means for selecting an ordinary node from ordinary nodes each put in one of the reduced-power states, assigning a job to the selected ordinary node and driving the selected ordinary node to carry out the assigned job; and node control means for executing control to restore an ordinary node selected by the node select means to the normal operating state. The node select means selects an ordinary node from the ordinary nodes each put in one of the reduced-power states having different times of recovery to the normal operating state in accordance with an ordinary-node order starting with an ordinary node existing in a reduced-power state and having a short time of recovery to the normal operating state.
