OMPI_CRCP - Open MPI MCA Checkpoint/Restart Coordination Protocol (CRCP) Framework:
Overview of Open MPIs CRCP framework, and selected modules. Open MPI 1.10.2
General Process Requirements
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.
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 components 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
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.
