[RegCNET] Problem with the parallel version - Urgent help needed

[IMRAN NADEEM]

Hi Beatrice,

         In present parallel verion of RegCM, no. of gridboxes in
x-direction should be divisible by no. of cpu's to be used.
In your case no. of grid boxes (jx=51) is not divisible by no. of cpu
(nproc). If you want to run on 4 cpu's change jx to 52 or 48.

Regards
Imran
