Task allocation device, task allocation method, and storage medium storing task allocation program

Abstract

To reduce performance degradation due to a high-performance core's waiting for a processing result of a low-performance core in a multi-core processor including a plurality of cores with different running performance, included are a task pool that stores executable tasks for each computational core, a task scheduler, and a reference count analysis module that acquires hint information and a reference count estimation method from a running task and estimates a reference count of a task to be newly inserted into the task pool or a task existing in the task pool based on the specified method. The scheduler performs insertion and acquisition of a task by mainly using performance of the cores and the reference count.
