Branch run: request exceeds max nodex, alloc

Hello. I am a new user of ccsm3. I am trying to run a fully coupled FV B_PRESENT_DAY branch run of CCSM3 on franklin at NERSC using restart files. I built the model successfully, but when I run it, it crashes and says "request exceeds max nodes, alloc." I have a new NERSC account so i know my allocation did not run out. Am I suppose to edit the nodes options somehow? Any idea what might be wrong?

Thanks, Michael

It is not that your allocations have run out.
I think it is because you are asking for more nodes when CCSM tries to allocate them
than you asked for in the PBS -l mppwidth command at the top of your runscript.
It could also be some restriction on the number of nodes per job you are asking for, for
a particular queue and/or runtime
