[MITgcm-support] Re: High-resolution CS grids

[chris hill]

Hi Yuan,

  The scirpts under high_res_cube do generate high-resolution grids.
  However, it helps to have a 64-512 processor system to run these 
calculations on and the runs generate very large output datasets.

  What sort of resolutions and grid point counts do you think you need 
for your problem?
