opal-checkpoint

OPAL-CHECKPOINT(1)						       1.4.5							OPAL-CHECKPOINT(1)

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 sequen-
       tial 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.
