[MITgcm-support] Computation time

[chris hill]

Hi Eli,

  The code computes over land points in general.

  For configurations with large numbers of points e.g. 1/6 and higher 
resolution globally you can use tiling to throw away regions with no land.

  For smaller configurations the overhead of skipping land points in do 
loops actually costs more than doing null computations, so that the 
shortest time to solution comes with computing that includes land.


  What size of problem are you running and how long are your runs taking?
