Reusable message passing components

Reusability of executables is an integral part in the design and implementation of message passing programs, as from the same executable component a number of interacting processes are spawned. In practice, reuse of executables within an application is usually achieved when processes execute within a specific regular topology and within a specific message passing environment (e.g. PVM, MPI). We propose the design and implementation of reusable message passing components, which are independent of the target message passing environment (MPE) and may be used in any topology, whether regular, partially regular or irregular. We define virtual process communication interfaces independent of any topology. Process topologies are established by associating compatible communications interfaces.
