Summary: Clusters of workstations are an attractive environment for high performance computing. For some applications, however, clusters still lack certain properties. One such property is responsive (dependable and timely) execution of programs. This paper studies two mechanisms (checkpointing and replication) to improve the responsiveness (the probability of meeting a deadline in the presence of faults) of a parallel programming system, Calypso, by ameliorating a single point of failure of Calypso. Experiments show that checkpointing is a suitable tool to achieve high responsiveness and that already a very modest degree of replication is sufficient for improved responsiveness.
