confusion

[Paul Van Allsburg]

I am trying to learn how to correctly add mpiexec-0.80 from OSU and 
LAM/MPI on a small cluster running FC3, torque-1.2.0p2 and Intel's 
Cluster tools(MPI  library).  I want to be able to use Torque to 
submit/control MPI jobs the cluster. Users currently use torque and 
submit(qsub) jobs, of which none of these apps require MPI (as of yet).

My confusion revolves around too many versions of mpiexec, and to what 
extent does mpiexec-0.80 setup the MPI environment.  As a rookie, I'm 
swamped in old/new documentation and can't see the forest for the trees.

Torque will manage the resources & start jobs with available node lists,
if mpiexec-0.80  is used to start an MPI aware app
    is it still required to do
	lamboot
	mpiexec
	and lamhalt?
    Or does mpiexec-0.80 setup the boot-schema?

The same question exists with Intel's environment of
	mpdboot
	mpiexec
	and mpdallexit

Clear as mud?
Thanks all,

Paul
