摘要:

JAPS-II(Java automatic parallelizing system version 2)是一个Java源代码重构编译器,用来发现和实现串行Java程序中对象内和对象间的并行性.其目标体系结构为基于工作站网络环境的分布式存储器计算机系统.介绍了JAPS-II的体系结构和实现JAPS-II的关键技术,包括用于对象并行性分析的数据流分析技术、提高对象并行性和减少运行开销的优化技术以及类重构和代码生成技术.测试结果表明,JAPS-II能够有效地发现循环中和对象内、对象间的并行性,获得加速比.这

JAPS-II: a Parallelizing Compiler for Java

YUMeng,CHEN Gui-hai,YANG Xue-lin,XIE Li,GUO Min-yi

Abstract:

JAPS-II (Java automatic parallelizing system version 2) is a Java parallelizing compiler that exploits and implements intra and interobject parallelism of serial Java programs. Its target architecture is NOW based on distributed memory computer system. In this paper, the infrastructure of JAPS-II and the key techniques to implement JAPS-II which include dataflow analysis for analyzing object parallelism, optimization for improving object parallelism and reducing executing cost, and techniques of class restructure and code generation are introduced.Related experiment results are also included.

Key words: parallelizing compiler parallel computing object-oriented language object distribution
