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.
