Fault Tolerance in MPI Programs
William Gropp, Ewing L. Lusk · 2009
This paper examines the topic of writing fault-tolerant MPI applications. We discuss the meaning of fault tolerance in general and what the MPI Standard has to say about it. We survey several approaches to this problem, namely checkpointing, restructuring a class of standard MPI programs, modifying MPI semantics, and extending the MPI speci cation. We conclude that within certain constraints, MPI can provide a useful context for writing application programs that exhibit signi cant degrees of fault tolerance.
