Abstract: An information processing apparatus includes: a processor performs a scheduling process of scheduling a job for nodes and including: calculating, when one node executes a first job, a job execution end time when execution of the first job is completed by referring an execution history in which an execution time of a job is recorded; acquiring, from a load management node that manages a load of a metadata-process execution node which performing metadata processing to access metadata of a file among the nodes, the load of the metadata-process execution node at the job execution end time; and generating, when the load is equal to or more than a threshold, schedule data to cause a staging execution node which performs the metadata processing produced by staging, at the job execution end time, the metadata processing based on staging to a file having an execution result of the first job.

Abstract: An apparatus includes nodes each configured to relay data between the nodes. When a failure occurs in a first-node, a management-node determines, based on power consumption and/or memory usage of the nodes, a collection-node that transmits an instruction in first direction approaching the first-node and a second direction approaching a storage-node, respectively. A second-node that is neither an adjacent-node adjacent to the first-node nor the storage-node, upon receiving data including the instruction, transmit data obtained by adding an evaluation value for the second-node to the received data, in the first or second direction. Each of the adjacent-node and the storage-node, upon receiving data including the instruction, transmit data including an evaluation value for another node included in the received data and an evaluation value for the each node, to the collection-node which determines transmission routes between the collection-node and the first-node, and between the collection-node and the storage-node.

Abstract: A data transfer control apparatus controls transfer of data from a plurality of first nodes included in a first region in a network to a plurality of second nodes included in a second region in the network. A control unit of the data transfer control apparatus generates an n-dimensional Latin hypercube in which the number of symbols in each dimension is a value in keeping with a size of the first region. The control unit then associates, in accordance with respective positions of the first nodes in the first region, each first node with a symbol at a corresponding position in the Latin hypercube. The control unit then instructs the first nodes so that parallel data transfers by a plurality of first node sets, where first nodes associated with a same symbol in the Latin hypercube are grouped, are executed in order in first node set units.

Abstract: A storage control device includes a processor. The processor is configured to acquire a first size. The processor is configured to calculate, for each of a plurality of storage devices, a total size of first data stored in each of the plurality of storage devices. The first data satisfies a predetermined condition. The processor is configured to select the first data in an ascending order of the total size. A sum of the total size of the selected first data is the first size or less. The processor is configured to copy the selected first data from the plurality of storage devices to a first storage device different from the plurality of storage devices.
