【摘要】 <正> 一、引言 1.1 自动并行编译的提出并行程序设计基本上有两种途径:显式途径和隐式途径。研究者设计了很多的并行程序设计语言,这就是所谓的“显式途径”。但是,并没有一种并行程序设计语言成为流行的语言,主要的问题在于并行程序的编制困难,对程序员的要求高。相比较而言,隐式途径,即自动并行编译技术就有许多的优势。用户使用串行语言编制程序,由自动编译更多还原

【Abstract】 The technology about expression transformation is a very important work during the pre-process phase of automatic parallelizing compiling. The source program can fit the system more after the processing. Expression transformation’ s emphases vary in different systems. This paper put forward a new technology on expression transformation aim at NOW-based JAPS (Java Automatic Parallelizing Compiling System),during which method-call can be separated from expression based on the principle of correctness,proper granularity and simpleness.更多还原
