EasyGrid: towards a framework for the automatic Grid enabling of legacy MPI applications

One of the goals of the Grid is to aggregate collections of shared, heterogeneous, and distributed resources to provide computational ‘power’ to parallel applications. However, designing applications capable of exploiting this potential with ease remains a challenge. This paper outlines the EasyGrid methodology for the efficient and robust execution of (legacy) MPI programs across distributed computing clusters. The principal objective of this work is to identify the application-oriented middleware necessary for, as well as to develop a framework to automatically generate, system-aware applications capable of executing in dynamic, unstable, distributed environments such as computational Grids.
