ompi-checkpoint

OMPI-CHECKPOINT(1)						     Open MPI							OMPI-CHECKPOINT(1)

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 (identified 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 contexts. <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
       checkpointer to be used here, as that is determined completely by each of the running process in the job being checkpointed.
