Abstract: Effective management and scheduling of resources can increase the utilization of grid system.For the issues of task-balancing in grid computing,in order to reduce the communication,a distributed scheduling pattern in grid is proposed,and the relevant algorithm is given.The algorithm collects each light load node to a queue,and sets an adjustable refresh time,when the heavy load nodes requests to schedule,the task will be transferred to the node which is taken out from the queue so as to solve the issues of task-balancing in grid.

Key words: computational grid, task, scheduling pattern
