P-RIO: An Environment for Modular Parallel Programming

This paper presents the P-RIO environment which offers high level, but straightforward, concepts for parallel and distributed programming. A simple software construction methodology makes most of the useful object oriented programming technology properties available, facilitating modularity and code reuse. This methodology promotes a clear separation of the individual sequential computation components from the interconnection structure used for the interaction between these components. The mapping of concepts associated to the software construction methodology to graphical representations is immediate. P-RIO includes a graphical programming tool, has a modular construction, is highly portable, and provides runtime support mechanisms for parallel programs, in architectures composed of heterogeneous computing nodes.
