In your pbs_mom.conf you could put:

$usecp *:/home /home

if on all clients ('*') that submit to Torque the /home
directory is the same as your /home on the compute nodes.

By default the pbs_mom will try and rcp/scp the users
files back, if your systems aren't configured for that
then you'll find output and error files going astray for

The usecp command just tells it to just cp the files
directly back rather than scp/rcp them.

It's a hold over from when systems didn't necessarily
have shared filesystems between them.
