This paper examines the issue of dynamically scheduling applications on a wide-area network computing system. We construct a simulation model for wide-area task allocation problem and study the performance of the proposed algorithm under different conditions. The simulation results indicate that the wide-area scheduling algorithm is sensitive to several(More)
