|Abstract:||Grid workflow scheduling, a very important system function in current Grid Systems, is known as a NP com plete problem. In this paper, we propose a new scheduling method- "temporal decomposition" - which divides a whole grid workflow into some sub-workflows. By dividing a large problem (workflow) into some smaller problems (sub-workflows), the "temporal decomposition" to better exploit achieves much lower computation complexity. Another motivation for the design of "temporal decomposition" is at the availability of the highly dynamic grid resources. We further propose an efficient scheduling algorithm for scheduling sub-workflows in this paper. Numerical simulation results show that our proposed scheme is more efficient in comparison with a well known existing grid workflow scheduling method.|
