摘要

多核机器在单个主板上的每个CPU有多个执行单元。随着多核机器的出现,并行化已经成为近年来编译器研究的重要组成部分。为了利用多核架构的固有能力,并行解析是仍然需要大量工作的领域之一。本文提出了一种在多核架构下对C程序进行并行语法分析的算法。对GCC 4.8.3中C文件的语法分析,实现了6级的合理提速。

Parallel syntax analysis on multi-core machines
A multi-core machine has more than one execution unit per CPU on single motherboard. With the advent of multi-core machines parallelization has become an essential part in recent compiler research. Parallel parsing is one of the areas that still needs significant work to utilize the inherent power of multi-core architecture. This paper presents an algorithm that performs parallel syntax analysis of C programs on multi-core architecture. Reasonable speed-up up to 6 was achieved on syntax analysis of C files of GCC 4.8.3.
