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.
