[RegCNET] mpirun error with pgi 7.1 and AMD Opteron x86-64

[Travis O'Brien]

Hello Paulo,

You might be able to get past this model crash by reducing the model 
timestep (dt) in regcm.in.  There are guidelines for how to change dt 
(and abatm, which should be changed at the same time) written in the 
RegCM User's Manual.  At this point, you could either restart the model 
from the beginning, or you could possibly restart the model from the 
most recent SAV file in the output directory.

I hope that this helps!
