P-RIO: a modular parallel-programming environment

The authors discuss the development of their Parallel Reconfigurable Interconnectable Object (P-RIO) environment, which offers a graphical programming tool, modular construction, high portability, a separate configuration language, and runtime support mechanisms for parallel programs. P-RIO provides a middleware-based environment for parallel and distributed programming. Its object-based, software construction methodology facilitates modularity and code reuse, allowing engineers and scientists with little training to build relatively complex programs.
