Q: What's new in PPPL Cluster RHEL4 release?

A: From a user point view, there are a few things that are different from RHEL3 clusters:

	1. A user must load ppplcluster module.  It is loaded automatically for a user upon 
	   log into portalr4.  But you might need it if you run qsub in a script or run into
	   any problem.  "module purge; module load ppplcluster" will put you back on track.

	2. MOAB scheduler does enforce memory limits for a running job.  The default is 
	   500,000 KB.  If you need more, use "#PBS -l mem=600mb", for example, in your job 
	   script.
