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.
opal-checkpoint [ options ] <PID>
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
-gmca | --gmca <key> <value>
Pass global MCA parameters that are applicable to all
contexts. <key> is the parameter name; <value> is the
-mca | --mca <key> <value>
Send arguments to various MCA modules.
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.
