[MITgcm-support] problem running tutorial_global_oce_latlon

[Samar Khatiwala]

Hi Jean-Michel

I tried a lower optimization, but that did not fix the problem.

What worked however is increasing OLx and OLy from 3 to 4. Now the  
model runs fine.

More puzzling still is that the model runs fine with the original OLx  
and OLy on a Mac with ifort+gcc.
Both the Linux box and Mac have the same version of ifort (10.1).

Any ideas what might be going on?

Thanks, Samar
