NAME
       OMPI_CRCP  -  Open  MPI	MCA Checkpoint/Restart Coordination Protocol (CRCP) Framework: Overview of Open MPI's CRCP framework, and selected
       modules.  Open MPI 1.4.5

DESCRIPTION
       The CRCP Framework is used by Open MPI for the encapsulation of various Checkpoint/Restart Coordination Protocols (e.g., Coordinated, Unco-
       ordinated, 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.
