Interesting, why so ? I know a number of sites around Australia
(including a
1900+ CPU cluster) run Gaussian using PBS (I don't know how much
pain, if
any, they went through for that but my understanding is that
anything else
that involves Gaussian involves pain and many dead chickens).
Linda and PVM* need some kind of rsh/ssh between the nodes, and I
didn't get a clue up to now to convince Linda to use the PBS TM of
Torque. As you mentioned in your other post about keeping control of
MPI processes, the similar thing to TM is the qrsh command in SGE,
which will replace rsh/ssh and SGE is controlling this way these
spawned processes on the nodes. I'm also always looking in a cluster
setup, without any common rsh/ssh between the nodes at all, where
users could by accident start processes out of control of the queuing
system on the nodes.

* I'm aware, that PVM can be started interactively without any rsh/
ssh between the nodes, by supplying some strings to the daemons and
its response back to the startup process.
My memory is that the one time I've had to set up a PVM dependant
application
(TGICL) it wasn't particularly hard to get going. Mind you PVM
seems pretty
dead, TGICL was the only application we've ever had requested that
needed it
and that was a couple of years ago and was only for a couple of
weeks work.
cheers!
