【Abstract】 The scheduling policy and algorithm of grid workflow determine the execution efficiency of grid workflow tasks,which is the core technology of grid workflow.Based on the definition of grid workflow tasks dynamic ready queue,key factor,dynamic factor and prior factor,the grid workflow tasks selection algorithm,resource selection algorithm and tasks allocation algorithm are presented,which constitute the workflow dynamic adaptive scheduling with multiple policies.Its can handle the dynamism of grid and resource.Some simulation experiments are implemented and analyzed,which show that the algorithm has the advantage of efficiency and practice.更多还原
