The SIMGRID Project Simulation and Deployment of Distributed Applications

This paper presents the SlMGRlD software architecture that comprises of four main components: SURF, MSG, GRAS, and SMPI. The last three components provide APIs for implementing, simulating and/or deploying distributed applications. The first component, SURF, is a fast and accurate simulation engine. The article describes all four components in terms of their goals, their usage, and their functionality, including experimental validation results when applicable. We review each components below
