Abstract: Provided herein is a real-time QoS monitoring apparatus, including an application registration unit configured to register at least one monitoring target application program for QoS measurement; a function explorer unit configured to detect user-defined functions in application code of the at least one monitoring target application program; a loop-statement explorer unit configured to detect loop-statements in the application code; a user-defined location explorer unit configured to detect user-defined locations in the application code; and a heartbeat generator configured to generate a plurality of heartbeat calls to correspond to the functions detected by the function finder, the loop-statements detected by the loop finder, and the user-defined locations detected by the user-defined location finder. Accordingly, there are provided a real-time QoS monitoring apparatus and method, which may measure QoS in real time without additionally modifying the application program.

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.
