ABSTRACT
The tremendous potential of grid computing is efficient scheduling, to exploit the computationally intense problems. In the commonly used decentralized models, large scale scheduling implies time sequence constraints, which makes the models intractable. To resolve this constraint, disintegration and cyclic scheduling are often applied to such scheduling which is time consuming and introducing more complexities. The significance of this paper is marked by speed and efficiency that the task-resource mapping in such a non-deterministic computing environment leads to concerns over scheduling problem to minimize the expected makespan and delay in allocation of tasks thereby reduce the turnaround time for precedence-constraint tasks imposed by application tasks to identify suitable resources. Our rigorous performance evaluation shows that our variant Expeditious Matching algorithm generates schedules with smaller makespan and higher robustness compared with other existing approach gratuitous to the new enhancement.
