[MITgcm-support] ifort

[Gus Correa]

Hi Nataliya

I am glad to know that you solved the problem.

I can't comment on gfortran, which I never used, sorry.
I'd guess gfortran would compile MITgcm without problems,
but for performance you need to test.

I've been compiling MITgcm with (PGI) pgf90 so far.
I may try it with Intel Fortran one of these days.
I have used Intel Fortran to compile other models, particularly GFDL's 
MOM4 and AM2.1,
which won't compile with PGI compilers anyway.

There is not a lot of C code in MITgcm, so I would guess that using gcc 
or Intel icc
along with  ifort would not make much of a difference.
I have used this type of mix to compile MPICH2 and NetCDF, for instance, 
and it works fine.
We don't have Intel C here, only Fortran.

Gus
