摘要： 本文主要概述了计算机体系结构的发展趋势以及相应的程序设计语言必然向分布式并行语言方向发展。文章中归纳了分布式程序设计语言研制的两种途径,重点介绍了一种新型的分布式并行程序设计语言——OCCAM。OCCAM既是一种分布式多机并行系统设计的系统程序设计语言,又是一种面向应用和教学的并行程序设计语言。它适合于科学计算,数字处理,实时系统的程序设计。最后,文章给出了在IBM——PC机上,UCSD——P系统支持下的并行算法及其结构的OCCAM模拟程序。

Abstract: The development trend of computer architecture is toward distributed parallel processing, which overcomes the restraints of conventional sequential computers. In order to achieve the maximum performance, programming languages must be adapted to describe the distributed parallel problems. A new, first of its kind distributed parallel programming language OCCAM is introduced which can be used in system programming design, application area and distributed programming learning, finally, examples on IBM/PC show OCCAM is excellent in describing parallel computing and data processing.
