Our focus is on the novel use of a process-oriented methodology in software systems for parallel simulation on distributed memory. To the best of our knowledge, the few existing systems which adopt a process view strictly use message passing to effect process interaction in distributed-memory settings. As a result, these systems avoid scenarios in which processes directly access passive but shared components. This can restrict the manner in which a system is modeled and hinder the phase of distributed model construction. In this paper, we propose an approach which utilizes mobile processes in distributed-memory simulation systems. The approach entails the migration of a requesting process with its timestamp to the remote site hosting the requested passive object. Major advantages of this approach include one-time transmission, fixed communication topology, and increased locality of reference. Empirical results based on lightweight processes show that the mobile process paradigm can be as efficient as the message-passing paradigm.
