orte-restart(1) [debian man page]

OMPI-RESTART(1) 						     Open MPI							   OMPI-RESTART(1)

NAME

       ompi-restart, orte-restart - Restart a previously checkpointed parallel job using the Open PAL Checkpoint/Restart Service (CRS)

       NOTE:  ompi-restart, and orte-restart are all exact synonyms for each other. Using any of the names will result in exactly identical behav-
       ior.

SYNOPSIS

       ompi-restart [ options ] <GLOBAL SNAPSHOT HANDLE>

Options
       ompi-restart will attempt to restart a previously checkpointed  parallel  job  from  the  global  snapshot  handle  reference  returned	by
       ompi_checkpoint.

       <GLOBAL SNAPSHOT HANDLE>
		 The  global snapshot handle reference returned by ompi_checkpoint, used to restart the job. This is required to be the last argu-
		 ment to this command.

       -h | --help
		 Display help for this command

       -p | --preload
		 Preload the checkpoint files on the remote systems before restarting the application. Disabled by default.

       --fork	 Fork off a new process, which is the restarted process. By default, the restarted process will replace ompi-restart.

       -s | --seq
		 The sequence number of the checkpoint to restart from. By default, the most recent sequence number is used (specified by -1).

       -hostfile | --hostfile
		 The hostfile from which to restart the application. Useful in unscheduled environments. (Same behavior as --machinefile option)

       -machinefile | --machinefile
		 The machinefile from which to restart the application. Useful in unscheduled environments. (Same behavior as --hostfile option)

       -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

       ompi-restart can be invoked multiple, non-overlapping times. This allows the user to restart a previously running parallel job.

NAME

       opal-checkpoint - Checkpoint a running sequential process using the Open PAL Checkpoint/Restart Service (CRS).

       Note:  This should only be used by the user if the application being checkpointed is an OPAL-only application. If it is an Open RTE or Open
       MPI program their respective tools should be used.

SYNOPSIS

       opal-checkpoint [ options ] <PID>

Options
       opal-checkpoint will attempt to notify a running process that it has been requested that the process checkpoint itself. A  snapshot  handle
       reference is presented to the user, which is used in opal_restart to restart the process.

       <PID>	 Process ID of the running target process.

       -h | --help
		 Display help for this command

       --term	 After checkpointing the running process, terminate it.

       -v | --verbose
		 Enable verbose output for debugging.

       -n | --name
		 Request a specific name for the local snapshot reference.

       -w | --where
		 Request that the local snapshot reference be placed in a specific location.

       -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

       opal-checkpoint	can  be invoked multiple, non-overlapping times. This allows the user to take involuntary checkpoints of a running sequen-
       tial process. See opal_crs(7) for more information about the CRS framework and components. 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 the running process being checkpointed.
