[torqueusers] epilogue.parallel?

[Troy P Chuang]

Hi all,
Does epilogue.parallel really exist?
It is mentioned in both
http://www.clusterresources.com/products/torque/docs20/a.gprologueepilogue.shtml
http://www.clusterresources.com/products/torque/docs/4.3prologueepilogue.shtml

However, the script /usr/spool/PBS/mom_priv/epilogue.parallel that I 
created never get executed.

Or is there any epilogue-script mechanism that will be performed on all 
sister nodes AFTER a parallel job finished (not necessary an mpi job)?
Specifically, I would like to reverse the changes I made by 
prologue.parallel (ex. reverse the changes made to /etc/authuser or 
/etc/security/access.conf.

Thanks
