Grid scheduling model based on Petri net

摘要

In order to solve the task allocation and scheduling problem, based on the analysis and research of hierarchical Petri net, this paper proposed a grid scheduling model based on hierarchical scheduling model. This model can ensure that the various elements of the loose coupling between the scheduling, to facilitate data resources deployment in grid environment; in addition, this paper proposed thought of the variable structure Petri network, through this technology can dynamic adjust work modeling and resource allocation, and to support the mission of exception handling; finally, to verify the rationality of the scheduling algorithm, and analyzes the performance and the efficiency of resource allocation algorithm.
