Ahhhh, here is the difference.  I must be missing some step that's assumed by
the rest of y'all.  I install Torque on server and clients, then create the
nodes file manually, inserting node1 np=2 (or whatever) for each node.  Mind
you, the nodes might already be running pbs_mom which is valiantly trying to
contact pbs_server.  But I've run pbs_server -t create as specified in the
docs.  Does the -t create mode also try to automatically create node entries?

Ah, good.  Those are the only reasons I've ever touched that file as well.

I see, I never made small changes to that file, so I'm realizing there's more
to it than I've ever cared to deal with.

Oooh.  _very_ good to know.

Thanks for the time to help clarify,
