I realised later that what I wrote was not sufficiently precise and it has
turned into this incorrect line in
http://www.clusterresources.com/products/torque/docs/2.1jobsubmission.shtml :

 "The ppn value is a characteristic of the hardware, system, and site, and its
value is to be determined by the administrator."

np is a resource attribute of the system and *its* value is determined by the
administrator.  ppn is a user request (determined by the user) for a quantity
of that system resource attribute.  I think you can just leave out that line.
