NAME
       opal-checkpoint  -  Checkpoint a running sequential process using the Open PAL Checkpoint/Restart Service
       (CRS).

       Note: This should only be used by the  user  if  the  application  being  checkpointed  is  an  OPAL-only
       application. If it is an Open RTE or Open MPI program their respective tools should be used.


SYNOPSIS
       opal-checkpoint [ options ] <PID>


Options
       opal-checkpoint  will  attempt  to  notify  a running process that it has been requested that the process
       checkpoint itself. A snapshot handle reference is presented to the user, which is used in opal_restart to
       restart the process.

       <PID>     Process ID of the running target process.

       -h | --help
                 Display help for this command

       --term    After checkpointing the running process, terminate it.

       -v | --verbose
                 Enable verbose output for debugging.

       -n | --name
                 Request a specific name for the local snapshot reference.

       -w | --where
                 Request that the local snapshot reference be placed in a specific location.

       -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
       opal-checkpoint can be invoked multiple, non-overlapping times. This allows the user to take  involuntary
       checkpoints of a running sequential process. See opal_crs(7) for more information about the CRS framework
       and components. 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 the running process being checkpointed.
