“…The message logging interposition layer can be inserted in the original MPI code, either bye employing the PMPI profiling interface [75], or by performing automated code injection in the original source code. Then, when a failure happens, it needs to be able to direct the cleanup of the damaged communicators, and silently swap them with replacements obtained from the ulfm communicator recreation functions [55,86].…”

As supercomputers are entering an era of massive parallelism where the frequency of faults is increasing, the MPI standard remains distressingly vague on the consequence of failures on MPI communications. In this chapter, we present the spectrum of techniques that can be applied to enable MPI application recovery, ranging from fully automatic to completely user driven. First, we present the effective deployment of most advanced checkpoint/restart techniques within the MPI implementation, so that failed processors are automatically restarted in a consistent state with surviving processes, at a performance cost. Then, we investigate how MPI can support application-driven recovery techniques, and introduce a set of extensions to MPI that allow restoring communication capabilities, while maintaining the extreme level of performance to which MPI users have become accustomed.
