APPARATUS AND METHOD FOR MAXIMIZING DISK CACHE EFFECT FOR WORKFLOW JOB SCHEDULING

摘要

PURPOSE: A device and method for scheduling a workflow task maximizing a disc cache effect are provided to utilize a feedback, which is from information in executing a task in a computing resource, for scheduling a next task, thereby maximally utilizing the computing resources in which the tasks are executed. CONSTITUTION: A device for scheduling a workflow task maximizing a disc cache effect includes a resource profiling management part (303), a resource detecting part (307), and a task dividing part (302). The resource profiling management part stores the resource use profile of a workflow including use information for the actual resource use amounts of computing nodes. While tasks are executed in unit computing resources, the resource detecting part measure the use information of a computing resource which the task in the unit computing resource actually uses, reports a measured result to the resource profiling management part, and then updates the resource use profile. The work dividing part loads the resource use profile of the resource profiling management part, and then selects one of the computing nodes.
