OPTIMIZATION INFORMATION ACQUISITION PROGRAM, OPTIMIZATION INFORMATION ACQUISITION DEVICE, AND OPTIMIZATION INFORMATION ACQUISITION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an optimization information acquisition program, an optimization information acquisition device, and an optimization information acquisition method which efficiently detect tasks capable of sharing a resource.SOLUTION: The optimization information acquisition program causes a computer to execute optimization information acquisition processing of detecting tasks capable of optimizing a resource of an operating system (OS). The optimization information acquisition processing comprises: task information acquisition processing of acquiring state information showing whether each task is in an invoked state or not including an executing state at prescribed time intervals by a hook routine called before and after dispatch processing of switching a task executed by a processor of the OS; and detection processing of detecting a first combination of tasks which do not simultaneously enter into the invoked state, as a task group capable of sharing a resource on the basis of state information at prescribed time intervals.
