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.
