Automated application-level checkpointing based on live-variable analysis in MPI programs

Abstract

This paper proposes an optimization method of data saving for application-level checkpointing based on the live-variable analysis method for MPI programs. We presents the implementation of a source-to-source precompiler (CAC) for automating applicationlevel checkpointing based on the optimization method. The experiment shows that CAC is capable of automating application-level checkpointing correctly and reducing checkpoint data effectively.
