Building Task-Oriented Applications: An Introduction to the Legion Programming Paradigm.

摘要

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.
