摘要： 针对网格环境中目前的资源预留机制导致排队任务(queued tasks)平均等待时间剧增的问题，提出了一种兼顾排队任务的资源预留机制，该机制中采用了一种新的策略，提出了一种动态确定n 的自适应算法。实验结果表明，该机制下排队任务的平均等待时间明显减少。

Abstract: In order to solve the problem that the mean wait time of queued tasks increase sharply when the resource reservation mechanism is introduced into grid, a resource reservation mechanism considering queued tasks is proposed, and a new strategy is used in the mechanism. An adaptive algorithm for determining the n value is presented. The experiment results show that the mean wait time of queued tasks decreases apparently in the mechanism
