.
\fIompi-restart\fR will attempt to restart a previously checkpointed parallel
job from the global snapshot handle reference returned by \fIompi_checkpoint\fP.
.
.TP 10
.B <GLOBAL SNAPSHOT HANDLE>
The global snapshot handle reference returned by \fIompi_checkpoint\fP, used to
restart the job. This is required to be the last argument to this command.
.
.
.TP
.B -h | --help
Display help for this command
.
.
.TP
.B -p | --preload
Preload the checkpoint files on the remote systems before restarting the
application. Disabled by default.
.
.
.TP
.B --fork
Fork off a new process, which is the restarted process. By default, the
restarted process will replace \fIompi-restart\fR.
.
.
.TP
.B -s | --seq
The sequence number of the checkpoint to restart from. By default, the most
recent sequence number is used (specified by -1).
.
.
.TP
.B -hostfile | --hostfile
The hostfile from which to restart the application. Useful in unscheduled
environments. (Same behavior as --machinefile option)
.
.
.TP
.B -machinefile | --machinefile
The machinefile from which to restart the application. Useful in unscheduled
environments. (Same behavior as --hostfile option)
.
.
.TP
.B -v | --verbose
Enable verbose output for debugging.
.
.
.TP
.B -gmca | --gmca \fR<key> <value>\fP
Pass global MCA parameters that are applicable to all contexts. \fI<key>\fP is
the parameter name; \fI<value>\fP is the parameter value.
.
.
.TP
.B -mca | --mca <key> <value>
Send arguments to various MCA modules.
