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 behavior.

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 argument 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.

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