NAME

       OMPI_CRCP  -  Open  MPI  MCA  Checkpoint/Restart  Coordination  Protocol (CRCP) Framework:
       Overview of Open MPI's CRCP framework, and selected modules.  Open MPI 1.6.5

DESCRIPTION

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

GENERAL PROCESS REQUIREMENTS

       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.

AVAILABLE COMPONENTS

       Open MPI currently ships with one CRCP component: coord.

       The following MCA parameters apply to all components:

       crcp_base_verbose
           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:

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

       crcp_coord_verbose
           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.
