Abstract: The Legion programming system from Stanford University was developed to address the specific needs of portable parallel heterogeneous programming with emphasis on program data. Data-centric Legion abstracts the underlying hardware such that the focus is algorithmic development rather than the idiosyncrasies of different computing architectures. Legion is part of a small but growing movement to treat parallel programming design and development in a task-oriented fashion and, as of this writing, is the only one to address this paradigm dynamically. This work employs a gravitational n-body simulation as a vehicle to introduce Legion to a wider audience of parallel programmers.
