A dump management apparatus having a memory; and a processor that executes a process including: selecting, in response to receiving a notification of an occurrence of a failure from a failure node of a parallel computer having a plurality of nodes, a plurality of nodes that are not scheduled to execute a job within at least a first time needed to perform dump processing of a memory of the failure node and have a memory capacity needed to perform the dump processing as dump-processing target nodes from among a plurality of nodes within a reference range near the failure node; selecting the dump-processing target nodes with a first priority according to which a plurality of adjacent nodes are preferentially selected as a candidate over a plurality of dispersing nodes from among candidates for the dump-processing target nodes; and causing the failure node to transfer a dump file inside the memory of the failure node to memories of the dump-processing target nodes.

A requested title recognizing mechanism recognizes the title of a video requested by the subscriber. A VOD service state monitoring mechanism determines whether or not the broadcast of the video is to be provided in the FVOD or the NVOD service, and if there is any available channel for the broadcast. If the broadcast has not been switched from the FVOD service to the NVOD service, then a busy state monitoring mechanism checks the number of the current simultaneous subscribers for the video. If the number is equal to or larger than a threshold, then the busy state monitoring mechanism instructs an NVOD service providing mechanism to broadcast the requested video in the NVOD service. If the number is smaller than the threshold, then the busy state monitoring mechanism instructs an FVOD service providing mechanism to broadcast the requested video in the FVOD service.
