Scheduling Scheme based on Dedication Rate in Volunteer Computing environment
Abstract: The volunteer node can leave from and join to volunteer computing system freely. Since existing volunteer computing systems do not consider dynamic property (i.e. volatility) such as leave, join and suspension in scheduling, they suffer from interruption of job execution, delay of execution time and increase of total execution time. Therefore, ynamic execution properties of volunteer nodes should be considered in scheduling scheme in order to design a stable and reliable volunteer computing system. In this paper, we propose new scheduling scheme based on Dedication Rate which reflects dynamic properties of volunteer. Our scheduling scheme improves completeness and reliability of execution, and decreases delay time and total execution time. In addition, we describe the implementation of the proposed scheduling scheme in the KOREA@Home and performance evaluation.
