[OMPI users] How to restart a job twice

[Tamer]

Dear all, I installed the developer's version r14519 and was able to  
get it running. I successfully checkpointed a parallel job and  
restarted it. My question is how can I checkpoint the restarted job?  
The problem is once the original job is terminated and restarted later  
on, the mpirun does not exist anymore (ps -efa|grep mpirun) and hence  
I do not know which PID I should use when I run the ompi-checkpoint on  
the restarted job. Any help would be greatly appreciated.
