| 摘 要： | 从并发分布式程序设计的角度,对现有的并发分布式语言进行分析比较,选取Jayadev Misra教授近几年提出的全新结构化并发分布式语言Orc作为研究对象。通过深入分析Orc语言的基本原理和语言特征,提出了一个能够适合Apla抽象程序设计语言的并发分布式机制,设计了并发算子、并发语句、进程定义、进程通信和进程同步,并通过实例探讨了该设计方案的可行性和实用性,最后阐述了Apla语言中并发分布式机制具有通用性强、抽象层次高、简单易懂、便于并发分布式程序的开发等优点。

| Abstract: | From the viewpoint of concurrent and distributed programming, several concurrent and distributed programming languages were analyzed and compared. A novel structured distributed and concurrent language Orc was designed and implemented by Professor Jayadev Misra. After analyzing the fundamental principles and languagccharacters,a new concurrent and distributed mechanism of Apla (Abstract Programming LAnguage) was originally designed in the paper. The mechanism includes the concurrent operator, concurrent statements, the definition, communication and synchronization of process. hhe feasibility and practicability of the mechanism were illustrated by giving a representative example. Finally, many advantages (such as generality, simplicity, abstract, easy-to-writing) of the concurrent and distributed mechanism were presented. |
