ABSTRACT

Introduction Modeling and simulation (M&S) consists of modeling a real system Σ and developing its simulation program (or simulator of Σ). Assume a local simulator (LS) of a given system Σ is available and we wish to turn it into a distributed simulator (DS). In the DS case, the LS is partitioned into segments called federates, each federate being run by a separate host. Before implementing the DS (i.e., at design time) we wonder: will the DS execution time be shorter than LS one? (In some cases the DS may run slower than the equivalent LS.) To answer this question, we argue that the performance engineering (PE) process should be applied to various development phases of the DS.
