Hmmm.  Same for us.  And same timeframe.  I've found with the weather 
codes I use, regardless of how they profile, they want significantly 
more RAM than they claim to.  We've found them very comfortable in 
2GB/core.

*I* am still learning about other apps with some of our new users on a 
cluster we're still getting into production.  We've bought some nodes w/ 
4GB/core for specific apps for one of our stakeholders, but we don't 
know if others' problems will need or benefit from that.
