[OMPI users] Determining what parameters a scheduler passes to OpenMPI

[Sasso, John (GE Power & Water, Non-GE)]

For the PBS scheduler and using a build of OpenMPI 1.6 built against PBS 
include files + libs, is there a way to determine (perhaps via some debugging 
flags passed to mpirun) what job placement parameters are passed from the PBS 
scheduler to OpenMPI?  In particular, I am talking about task placement info 
such as nodes to place on, etc.   Thanks!
