Analyzing the Control Structure of PEPA

    Research output: Contribution to conferencePosterResearch

    Abstract

    The Performance Evaluation Process Algebra, PEPA, is introduced by Jane Hillston as a stochastic process algebra for modelling distributed systems and especially suitable for performance evaluation. We present a static analysis that very precisely approximates the control structure of processes expressed in PEPA. The analysis technique we adopted is Data Flow Analysis. We begin the analysis by defining an appropriate transfer function, then with the classical worklist algorithm we construct a finite automaton that captures all possible interactions among processes. By annotating labels and layers to PEPA programs, the approximating result is very precise. Based on the analysis, we also develop algorithms for validating the deadlock property of PEPA programs. The techniques have been implemented in a tool which is able to analyze processes with a control structure that more than one thousand states.
