SYNOPSIS

ompi-checkpoint [ options ] <PID_OF_MPIRUN>

Options

orte-checkpoint will attempt to notify a running parallel job (identified by mpirun) that it has been requested that the job checkpoint itself. A global snapshot handle reference is presented to the user, which is used in ompi_restart to restart the job.

<PID_OF_MPIRUN>

Process ID of the mpirun process.

DESCRIPTION

orte-checkpoint can be invoked multiple, non-overlapping times. 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 each of the running process in the job being checkpointed.
