Abstract

Heterogeneous computing environments, where computers may have different instruction set architectures, data representations, and operating systems, complicate checkpointing and recovery of processes. This paper descdbes an approach to recovery and ah implementation, PREACHES, that provides portable checkpointing of single-process applications in heterogeneous systems using checkpoint propagation. The checkpoint propagation mechanism creates machine-dependent checkpoints for different architectures in the heterogeneous environment. A process is restored on a specific machine with the checkpoint that is appropdate for the architecture. An implementation of PREACHES has been evaluated on a heterogeneous network of workstations, including Sun, HP, and Pentium machines. The experimental results show that PREACHES achieves efficient checkpointing anal rapid recovery.
