[MITgcm-support] size.h

[Michael Schaferkotter (Contractor)]

greetings:
i/ve successfully run the plume on the shelf problem and i want to modify the example.

looking in SIZE.h i see that:

     &           sNx = 160,
     &           sNy =   1,
     &           nSx =   2,
     &           nSy =   1,
     &           nPx =   1,
     &           nPy =   1,
     &           Nx  = sNx*nSx*nPx,
     &           Ny  = sNy*nSy*nPy,
     &           Nr  =  60)

the domain is 320x1x60.

why is nSx set to 2, i/m using a single processor (i think). there was nothing in the make that i could
see indicated multi-processor.

also, i couldn/t find the info on the web site about parallel setup. i have access to a bunch of machines and would
like to try an MPI run.
