Hi Shekhar

I'm running on an AMD 64 Athlon X2 using the command:

mpirun -machinefile mac -np 2 ./regcm<./regcm.in

The file mac contains only this line:

localhost.localdomain:2

The model is now running but it seems to be using only one processor.

Do you have examples of  other machine files ?

Any ideas of where the problem might be?
