Measuring Concurrency of Regular Distributed Computations
Résumé
In this paper, we present a concurrency measure that is especially adapted to distributed programs that exhibit regular run-time behaviours. Such programs are frequently obtained by automatic parallelization of sequential code. This measure is based on the antichain lattice of the partial order that models the distributed execution under consideration. We show under which condition the measure is computable on an infinite execution which is the repetition of a finite pattern. The measure can then be computed by considering only a bounded number of patterns, this bound being at most the number of processors.
