Hi Hailong,

Thanks for your suggestion, but I'm afraid that's not my case. I 
already work with unlimited stack size. And in my case, I get no error 
at all: wrf with 2 or more procs simply never ends for a rather quick 
simulation that with 1proc finishes ok. Besides, I've run several 
times in the same cluster huge MM5 and CMAQ simulations in paral.lel 
mode with up to 24procs without problems, so it should not be a 
problem regarding the cluster ability to work in paral.lel and/or with 
big simulations.

Best Regards,

Maite Merino
