网格远程调度系统的设计与实现

Design and Realization of an Efficient Grid RPC System

摘要:

阐明了在多集群的网格中,资源调度和任务的分配受到网络和通信延迟的限制,采用元调度机制有效的将作业分配到不同集群计算机中,进一步,又采用动态绑定机制来减少作业分配的延迟。这一机制是绑定相似的请求来组成复合请求分配到网格资源。在不同的服务负载下应用了这些机制,结果显示这些机制能够帮助获得负载均衡和减少作业分配的延迟,同时也能减少程序的运行时间。

Abstract:

On multi-cluster grid, resources are distributed across different networks. Hence, scheduling and dispatching jobs are difficult and inefficient due to the restrictions of network and the communication overhead. Met scheduling mechanism is developed to distribute jobs onto different clusters of computers effectively. Further, a dynamic bundling mechanism is provided to reduce overhead of job dispatching. This mechanism bundles similar requests to form a composite request that is dispatched to a grid resource. The above mechanisms have been tested with different types of services and loads, and the results show that they help to achieve more balanced workload and reduce the overhead of job dispatching. This cuts down execution time of applications.
