  We present a general model allowing static analysis based on abstract
interpretation for systems of communicating processes. Our technique, inspired
by Regular Model Checking, represents set of program states as lattice automata
and programs semantics as symbolic transducers. This model can express dynamic
creation/destruction of processes and communications. Using the abstract
interpretation framework, we are able to provide a sound over-approximation of
the reachability set of the system thus allowing us to prove safety properties.
We implemented this method in a prototype that targets the MPI library for C
programs.
