A Veil program analyzes the source code and/or data of an existing sequential target program without user interaction and determines how best to distribute the target program and data among the processing elements of a multi-processing element computing system. The Veil program analyzes source code loops, data sizes and types to prepare a set of distribution attempts or strategies, whereby each strategy is run under a run-time evaluation system and evaluated to determine the optimal decomposition and distribution across the available processing elements.
