【摘要】 近年来,随着科学研究对计算资源的要求不断增加,结合分布式计算环境和互联网的网格计算已经得到越来越多研究者的关注。网格计算就是利用网络中的空闲计算资源来协助那些要求大量计算的复杂任务的执行。根据分布式系统的静态和动态负载均衡策略的优缺点,本文提出了在网格计算环境下的混合负载均衡策略。为了让网络中的节点在网格计算环境中有效地执行需要大量计算的复杂任务,并根据大量的实验总结,提出了新的用来评估节点效率的函数,较以前的函数执行效率有了提高。更多还原

【Abstract】 In recent years, as the demands of many scientific researches for computing resources gradually grow, grid computing integrated with the distributed computing environment and the Internet has gained more attention from the researchers. Grid computing is to utilize the idle computing resources (nodes) on the network to facilitate the execution of complicated tasks that require large-scale computing. According to the advantages and disadvantages of static and dynamic load balancing policies in distributed systems, an omnibus load balancing policy in the grid computing environments is proposed. In order to make the nodes on the network effectively execute the complicated tasks that require large-scale computing in the grid computing environments, a new better function that evaluates the efficiency of nodes is also put forward according to a lot of experiments, which is better than the traditional algorithms.更多还原
