Hi  folks.

I've been testing ScalablePBS (SPBS) from supercluster.org for a few weeks now 
and it seems like a fairly good replacement for OpenPBS.  Only a few minor 
changes to the OpenPBS infrastructure were needed to accomplish the 
neccessary changes in the kickstart generation to make the nodes switch to  
SPBS.

SPBS is based on OpenPBS 2.3.12, but incorporates most provided patches 
(sandia etc) and is actively developed by the same maintainers that develop 
maui.  It scales better than OpenPBS, to around 2K nodes, has better fault 
tolerance and communicates better with maui.  It has, as far as I can see, no 
user visible changes from OpenPBS.

I know, a lot of people are moving away from pbs and into sge, I was thinking 
about making the switch too.  The emergence SPBS seems to make the switch 
unneccessary and I don't have to teach myself (and the users) a new queueing 
interface...

Configuration tested:
Rocks 3.0.0
SPBS 1.0.1p0 (should leave beta phase next month)
Maui 3.2.6p6 (available for "Early Access Production")

SPBS and Maui can be downloaded from http://www.supercluster.org/

Have a nice weekend,
r.
