[OMPI users] Automatic checkpoint/restart in OpenMPI

[ESTEBAN MENESES ROJAS]

   Hello.
   Is there any way to automatically checkpoint/restart an application in 
OpenMPI? This is, checkpointing the application without using the command 
ompi-checkpoint, perhaps via a function call in the application's code itself. 
The same with the restart after a failure.
   On a related note, what is the default behavior of an OpenMPI application 
after one process fails? Does the runtime shut down the whole application?
   Thanks.
