Abstract: In a resource allocation control device, a dependency information acquisition unit acquires dependency information indicating subdivided process items that constitute a task and a dependency of the process items. A resource information acquisition unit acquires resource information that is information indicating what kind of resource allocation is possible for the task. A score calculation unit calculates a score for a processing procedure of the process items based on the dependency information, and the resource allocation. A search unit searches for a combination of which the score is excellent. An output unit outputs resource allocation corresponding to the excellent score found by the search unit.

Abstract: A method for executing query processing includes, in response to a query from a host, generating a task graph indicating a plurality of task sequences, each of the task sequences capable f performing query processing corresponding to the query. The sequences includes a first sequence that outputs data in a first compression state to a one of output targets, and a second sequence of tasks that outputs the data in a second compression state different from the first compression state to the one of the output targets. The method further includes determining a processing cost for each of the task sequences, selecting one of the task sequences in accordance with the determined processing cost, and performing the query processing corresponding to the query in accordance with the selected task sequence.
