Wingrid-Parameter Sweep Oriented Grid Computational System

The parameter sweep applications play important roles in the computational grid environment.An adaptive scheduling schema for parameter sweep applications is proposed and implemented in our Wingrid project.The client, master and slave scheduling infrastructure and the leader-node-based communication system can improve the scheduling system efficiently.Also,we compare the adaptive workqueue algorithm with standard heuristics scheduling algorithms.The experiment results show that heuristics scheduling algorithms perform better than workqueue algorithm with larger network latency and the min-min heuristic has the shortest makespan among the heuristic algorithms.
