OMPI_CRCP(7)			   Open	MPI			  OMPI_CRCP(7)

NAME
       OMPI_CRCP  -  Open  MPI	MCA  Checkpoint/Restart	 Coordination Protocol
       (CRCP) Framework: Overview of Open MPI's	CRCP framework,	 and  selected
       modules.	 Open MPI 1.10.6

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

GENERAL	PROCESS	REQUIREMENTS
       In  order for a process to use the Open MPI CRCP	components it must ad-
       hear 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 Coordi-
       nation 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 OMPI_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.
