[torqueusers] a question about $usecp

$usecp needs to be enabled when you have your current working directory
(CWD) or really the directory you qsub'd from NFS (or AFS etc) mounted
on the compute nodes. Otherwise the compute nodes attempt to SCP (or in
builds without --with-scp, RCP) the .o and .e files.
For example, on basic clusters /home is NFS mounted on the compute nodes
as well as the submission nodes. So I need a line in mom_priv/config
that tells pbs_mom to simply "use cp" rather then rcp/scp
$usercp *:/home /home
If I then qsub a job out of /home/jbernstein, the output files get
copied using 'cp'.
If your jobs aren't even starting, then *.o and *.e files aren't being
created and there is another problem afoot.
