We present Tigris, a high-performance computation and I/O substrate for clusters of workstations, implemented entirely in Java. Tigris automatically balances resource load across the cluster as a whole, shielding applications from asymmetries in CPU, I/O, and network performance. This is accomplished through the use of a data ow programming model coupled with a workbalancing distributued queue....
