So /home is not mounted via NFS as it's usually done?

Yes, as it first wants to change to the user's home before the prolog is
started.

Yep.

How exactly is your setup? I mean: you want to create some kind of pseudo home
directory on the nodes (hence "-b y" can't be used with user binaries) and the
staged job script (by SGE) will then execute the job and/or copy some files
thereto too? Afterwards this directory would have to be removed too I guess
(and the results copied back beforehand).
