摘要： 主要从软件工程的角度讨论了一种Internet 环境下并行计算中间件(ParaCQ)的软件系统设计思想和工作原理。该中间件基于移动Agent 技术，融合了基于元组空间的协作模型，采用基于好友协商策略的P2P 的资源共享模式，不仅支持同步、异步计算，也支持在线和离线计算。此外，它还具有友好的用户界面，简单的并行计算程序编程接口。因此，该并行计算中间件是在Internet 环境下推广与普及并行计算的有益尝试。

Abstract: This paper discusses a parallel computing middleware based on mobile agent for Internet user. This middleware can support not only synchronized and asynchronized computing, but also online and off line computing. This middleware also can overcome network latency and reduce network load while computing. Finally, this middleware has a friendly user interface, so users can develop parallel computing program easily. It’s believed that this middleware is a good attempt on parallel computing in Internet environment
