Abstract

Bracket languages play an important role in the syntax analysis of programming languages. We investigate the parallel recognition and analysis of these languages as a first step towards a parallelly working compiler. The main result consists in the design of an appropriate algorithm, which can be executed on hypercubes as well as on related networks with bounded degree. In the average case we can achieve an optimal speed-up, i.e. that q processors can together analyse bracket words of length N in time O(N/q), if we restrict ourselves to employing no more than \(\sqrt N\) processors.
