Hello,

Whilenusing NPROC=16 in a AMD Opteron dual core x86-64, using PGI compiler 7.1, I'm with problems to run regcm
my grid is with iy=232 and ix=160, ds=40.0

 when I types:
nohup mpirun -np 16 -machinefile machine.cluster  -nolocal regcm > log.out.txt &

but no full sucess.
the regcm run the 56 first days, exit with error mesg ->

Can somebody suggests me how to overcome this, please!


PS.: The problem can be ,  no. of points w/convection
