A high performance implementation of MPI-IO for a Lustre file system environment

It is often the case that MPI‐IO performs poorly in a Lustre file system environment, although the reasons for such performance have heretofore not been well understood. We hypothesize that such performance is a direct result of the fundamental assumptions upon which most parallel I/O optimizations...
