Application of QoS Based Grid Task Scheduling to On-Line Examination System

Application of grid task scheduling based on QoS (Quality of Service) in the on-line examination system are researched, the superior node scheduling algorithm was designed, grid task scheduling based on historical average complete time of job and load of grid node was designed and realized, grid on-line examination system was implemented. The system can provide grid resource access service by grid portal, each grid node can provide remote share of examination database and information service. The system has better QoS.
