摘要： 网格应用必须适应动态变化的运行环境。该文探讨动态且自适应的资源管理模式，设计并实现一种面向服务的分布式虚拟机——Abacus虚拟机。根据资源管理策略与运行时的可用资源情况，Abacus虚拟机自适应地在分布式环境中为应用程序分配资源。实验结果显示，该自适应的资源管理方式是可行有效的。

Abstract: Grid applications must adapt dynamically to changing run-time environments. This paper studies a dynamic and adaptive resource management model, designs and implements a service-oriented distributed virtual machine called Abacus VM. According to the resource management policy and run-time resource statistics, Abacus VM adaptively allocates resource for grid applications. Experimental results demonstrate that the adaptive resource management model is feasible and efficient.

Key words: grid, Web service, distributed computing, Virtual Machine(VM)
