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

.SH GENERAL PROCESS REQUIREMENTS
|
|
.PP
|
|
In order for a process to use the Open MPI CRCP components it must adhear to a
|
|
few programmatic requirements.
|
|
.PP
|
|
First, the program must call \fIMPI_INIT\fR early in its execution.
|
|
.PP
|
|
The program must call \fIMPI_FINALIZE\fR before termination.
|
|
.PP
|
|
A user may initiate a checkpoint of a parallel application by using the
|
|
ompi-checkpoint(1) and ompi-restart(1) commands.

.SH AVAILABLE COMPONENTS
|
|
.PP
|
|
Open MPI currently ships with one CRCP component: \fIcoord\fR.
|
|
.
|
|
.PP
|
|
The following MCA parameters apply to all components:
|
|
.
|
|
.TP 4
|
|
crcp_base_verbose
|
|
Set the verbosity level for all components. Default is 0, or silent except on error.
|
|
.
|
|
.\" Coord Component
|
|
.\" ******************
|
|
.SS coord CRCP Component
|
|
.PP
|
|
The \fIcoord\fR component implements a Coordinated Checkpoint/Restart
|
|
Coordination Protocol similar to the one implemented in LAM/MPI.
|
|
.
|
|
.PP
|
|
The \fIcoord\fR component has the following MCA parameters:
|
|
.
|
|
.TP 4
|
|
crcp_coord_priority
|
|
The component's priority to use when selecting the most appropriate component
|
|
for a run.
|
|
.
|
|
.TP 4
|
|
crcp_coord_verbose
|
|
Set the verbosity level for this component. Default is 0, or silent except on
|
|
error.
|
|
.
|
|
.\" Special 'none' option
|
|
.\" ************************
|
|
.SS none CRCP Component
|
|
.PP
|
|
The \fInone\fP component simply selects no CRCP component. All of the CRCP
|
|
function calls return immediately with ORTE_SUCCESS.
|
|
.
|
|
.PP
|
|
This component is the last component to be selected by default. This means that if
|
|
another component is available, and the \fInone\fP component was not explicity
|
|
requested then Open MPI will attempt to activate all of the available components
|
|
before falling back to this component.
