This proposal is a three-year RUI project to implement "AgentTeamwork", a mobile agent-based middleware system for coordinating distributed jobs in a computational community of computer owners. Each mobile agent represents a client user by carrying client job requests, searching for resources available for a given request, executing the job at suitable computers, and migrating it to other resources when needed. All the features of job migration will be encapsulated in a user program wrapper implemented on a Java layer between a mobile agent and the corresponding user program.The wrapper captures all execution state of the user program, and is carried by the agent upon a job migration. A user program is preprocessed with JavaCC and ANTLR to interact with its corresponding wrapper at run time. Previous work has implemented a mobile-agent execution platform, mobile agents running on top of this platform, a user program wrapper, and a inter-process communication library. The main objective of this proposed project is to complete the implementation, tie-in a language preprocessor, evaluate system performance, and disseminate the system and its design techniques to the public.

该提案是一个为期三年的RUI项目，旨在实现“AgentTeamwork”，这是一个基于移动代理的中间件系统，用于协调计算机所有者计算社区中的分布式作业。每个移动代理代表一个客户机用户，它携带客户机作业请求，搜索给定请求的可用资源，在合适的计算机上执行作业，并在需要时将其迁移到其他资源。作业迁移的所有特性都封装在用户程序包装器中，该包装器在移动代理和相应的用户程序之间的Java层上实现。包装器捕获用户程序的所有执行状态，并在作业迁移时由代理携带。使用JavaCC和ANTLR对用户程序进行预处理，以便在运行时与其相应的包装器进行交互。以前的工作实现了一个移动代理执行平台、运行在该平台之上的移动代理、一个用户程序包装器和进程间通信库。本计画的主要目标是完成实作，搭配语言预处理器，评估系统性能，并将系统及其设计技术传播给公众。
