Checkpointing and Recovery of Shared Memory Parallel Applications in a Cluster
Abstract
This paper describes issues in the design and implementation of checkpointing and recovery modules for the Kerrighed DSM cluster system. Our design is for a DSM supporting the sequential consistency model. The mechanisms are general enough to be used in a number of different checkpointing and recovery protocols. It is designed to support common optimizations for performance suggested in literature, while staying light-weight during fault-free execution. We also present preliminary performance results of the current implementation.
