NAME
ompi-checkpoint, orte-checkpoint - Checkpoint a running parallel
process using the Open MPI Checkpoint/Restart Service (CRS)
NOTE: ompi-checkpoint, and orte-checkpoint are all exact synonyms for
each other. Using any of the names will result in exactly identical
behavior.
SYNOPSIS
ompi-checkpoint [ options ] <PID_OF_MPIRUN>
Options
orte-checkpoint will attempt to notify a running parallel job (identi-
fied by mpirun) that it has been requested that the job checkpoint
itself. A global snapshot handle reference is presented to the user,
which is used in ompi_restart to restart the job.
<PID_OF_MPIRUN>
Process ID of the mpirun process.
-h | --help
Display help for this command
-w | --nowait
Do not wait for the application to finish checkpointing
before returning.
-s | --status
Display status messages regarding the progression of the
checkpoint request.
--term After checkpointing the running job, terminate it.
-v | --verbose
Enable verbose output for debugging.
-gmca | --gmca <key> <value>
Pass global MCA parameters that are applicable to all con-
texts. <key> is the parameter name; <value> is the parameter
value.
-mca | --mca <key> <value>
Send arguments to various MCA modules.
DESCRIPTION
orte-checkpoint can be invoked multiple, non-overlapping times. It is
convenient to note that the user does not need to spectify the check-
pointer to be used here, as that is determined completely by each of
the running process in the job being checkpointed.
