　　按需远程执行是软件应用实现对资源按需占有,从而保障性能并提高资源利用率的重要手段。给出了一种通过自动程序转换来支持Java应用中计算按需远程执行的方法,其核心是支持计算按需远程执行的设计模式。介绍了将Java应用转换成该模式所面临的技术挑战、处理机制以及DPartner转换系统。与已有工作相比,DPartner有两大特色：一是程序转换自动执行；二是转换后应用可实现真正按需的远程执行,使性能和资源利用率得以提升。此外,DPartner被设计为可对只有Java字节码的遗产应用进行转换,更具实用性。

On-Demand remote executing is an important way to enable an application occupy resource on-demand to guarantee performance as well as improve resource utilization. This paper proposes an automatic program transformation approach for the on-demand remote execution of the computations in a Java application. The core of the approach is a design pattern supporting on-demand remote execution of computations. The research presents the technical challenges of and solutions for transformation, and gives out the DPartner transformation system. Comparing with previous work, DPartner has two major characteristics: first, transformation is carried out automatically;second, the transformed application is able to execute remotely on-demand, so its performance can be improved and the resource utilization can be increased. Additionally, DPartner is designed to be a practicable tool, as it can transform legacy applications with only Java bytecode.
