I am also curious as to why this would not work -- I was not under the
impression that tm_init() would fail from a non mother-superior node...?
FWIW: It has been our experience with both Torque and the various
flavors of PBS that you can repeatedly call tm_init() and tm_finalize()
within a single process, so I would be surprised if that was the issue.
Indeed, I'd have to double check, but I'm pretty sure that our MPI
processes do not call tm_init() (I believe that only mpirun does).
Prakash: are you running an unmodified version of Torque 2.0.0p7?
