The Lattice Project: A Multi-model Grid Computing System

This thesis presents The Lattice Project, a system that combines multiple models of Grid computing. Grid computing is a paradigm for leveraging multiple distributed computational resources to solve fundamental scientific problems that require large amounts of computation. The system combines the traditional Service model of Grid computing with the Desktop model of Grid computing, and is thus capable of utilizing diverse resources such as institutional desktop computers, dedicated computing clusters, and machines volunteered by the general public to advance science. The production Grid system includes a fully-featured user interface, support for a large number of popular scientific applications, a robust Grid-level scheduler, and novel enhancements such as a Grid-wide file caching scheme. A substantial amount of scientific research has already been completed using The Lattice Project
