       OMPI_CRCP  -  Open  MPI  MCA  Checkpoint/Restart  Coordination Protocol
       (CRCP) Framework: Overview of Open MPI's CRCP framework,  and  selected
       modules.  Open MPI 1.4.3


       The CRCP Framework is used by Open MPI for the encapsulation of various
       Checkpoint/Restart   Coordination   Protocols    (e.g.,    Coordinated,
       Uncoordinated, Message/Communication Induced, ...).


       In  order  for  a  process  to use the Open MPI CRCP components it must
       adhear to a few programmatic requirements.

       First, the program must call MPI_INIT early in its execution.

       The program must call MPI_FINALIZE before termination.

       A user may initiate a checkpoint of a parallel application by using the
       ompi-checkpoint(1) and ompi-restart(1) commands.


       Open MPI currently ships with one CRCP component: coord.

       The following MCA parameters apply to all components:

           Set the verbosity level for all components. Default is 0, or silent
           except on error.

   coord CRCP Component
       The  coord  component  implements  a   Coordinated   Checkpoint/Restart
       Coordination Protocol similar to the one implemented in LAM/MPI.

       The coord component has the following MCA parameters:

           The component's priority to use when selecting the most appropriate
           component for a run.

           Set the verbosity level for this component. Default is 0, or silent
           except on error.

   none CRCP Component
       The  none  component  simply selects no CRCP component. All of the CRCP
       function calls return immediately with ORTE_SUCCESS.

       This component is the last component to be selected  by  default.  This
       means  that  if  another component is available, and the none component
       was not explicity requested then Open MPI will attempt to activate  all
       of the available components before falling back to this component.
