> 中文摘要: 面向对象的并行程序设计提供了类似于共享内存模型对通讯和计算的抽象能力,从而非常适合于大型并行软件系统的开发.但是基于远程对象调用的分布式对象的实现效率一直是面向对象方法在分布式/并行程序设计中得到广泛应用的障碍.本文介绍了并行机MANNA上所采用的面向对象的并行程序设计模型——Dual-Object模型.该模型通过引入从语义角度出发给出的数据一致特性的描述,在一定程度上解决了实现效率低下的问题.其次,文章通过程序设计实例详细地讨论了基于Dual-Object模型的扩展C++并行程序设计,并给出了部分实际测试结果.
Abstract:Objects provide a uniform treatment of both communication and computation similar to a shared memory model. Thus, object paradigm is suitable for construction of large parallel software system. ROI (remote object invocations) provide a natural mechanism for remote interaction between objects. Unfortunately, the invocation performance blocks the widespread of object oriented parallel programming paradigm. This paper introduces the Dual Object model for MANNA machine, which attacking the invocation overhead problem at a semantic level via annotations.Some examples and experimental data are presented to show this dual object programming with extended C++language.
