This merge adds Checkpoint/Restart support to Open MPI. The initial frameworks and components support a LAM/MPI-like implementation. This commit follows the risk assessment presented to the Open MPI core development group on Feb. 22, 2007. This commit closes trac:158 More details to follow. This commit was SVN r14051. The following SVN revisions from the original message are invalid or inconsistent and therefore were not cross-referenced: r13912 The following Trac tickets were found above: Ticket 158 --> https://svn.open-mpi.org/trac/ompi/ticket/158
