Abstract :
Circuit complexities reduce overall reliability and mean-time-between-failure rates of today´s very large processing arrays. Our integrated, three-level hierarchy of reconfiguration methods provides reasonable levels of fault tolerance for such systems. Operating in a completely distributed fashion, the hierarchy does not require that any components be fault free. It significantly improves array reliability by using a combination of transient fault rollback techniques and local and global reconfiguration algorithms.<>
