<pre wrap="">Just a quick note regarding Ken's r3806 patch, here is his very good changelog note:
When the server parameter auto_node_np is set to true it is suppose to set the
number of processors of a node to the value returned by the MOM in the ncpus
value as returned in pbsnodes. If the configured processor value is less than
ncpus the value is adjusted but if it is greater the value was not adjusted.
This fix enables pbs_server to adjust processor values down as well as up.
However, the previous behaviour of only increasing np wasn't a bug. It was done
on purpose because people wanted to oversubscribe nodes.
I don't care either way, but someone out there might bring it up.

Thank you for the heads up. <br>
If someone brings it up I will argue that if you want to oversubscribe
nodes then why would you want to use auot_node_np. Its purpose is to
automatically configure the number of processors to their real values.<br>
