US 2015/0100964 A1 · APPARATUS AND METHOD FOR MANAGING MIGRATION OF TASKS BETWEEN CORES BASED ON SCHEDULING POLICY

Abstract

Provided are an apparatus and method for managing migration of tasks between cores based on a scheduling policy, which can provide optimal environments utilizing multiple cores to the tasks with various characteristics. It is possible to schedule tasks in consideration of different characteristics. In particular, it is possible to continuously secure the performance of the multi-core system in an environment for operating a plurality of application programs. It is also possible to optimally utilize all cores of the multi-core system, thereby flexibly handling dynamic variation in characteristics of tasks.

Dependent claims

An apparatus for managing migration of tasks between cores based on a scheduling policy, the apparatus comprising:

a task characteristic analysis unit configured to analyze and classify characteristics of the tasks based on a resource allocation history about each task in a multi-core system;
a core-based scheduling policy setting unit configured to set scheduling policies specialized for the cores in the multi-core system based on the classified characteristics of the tasks;
and
a scheduling policy-based task migration management unit configured to manage migration policies of the tasks in consideration of the characteristics of the tasks analyzed using the scheduling policies.
