[MITgcm-support] problems with compile with MPI

[MIT]

Dear Lizhi,

the modification you made look reasonable.  Why don't you give it a try
and report back how it went?  The last part of your genmake2 command
looks funny, though.  It should just be

../../../tools/genmake2 -mods=../code
-of=../../../tools/build_options/linux_amd64_pgf90+mpi_xd1

And make sure your SIZE.h (in code) has nPx or nPy > 1.  If you don't
know how to modify SIZE.h, have a look at one of the verification
experiments, like verification/tutorial_barotropic_gyre.  SIZE.h_mpi is
the version for mpi with 2 processors.

Cheers,
Oliver
