[MITgcm-support] MITgcm on BCp2: domain decomposition

[Fanny Monteiro]

Hi,

   I have been compiling and running on parallel processors the MITgcm on
the HPC of the University Bristol (BlueCrystal Phase 2).

We had to make a few changes and I am wondering if anyone has an idea of a
better way of doing it (especially in relation to point 3).

Here are the changes that our IT specialist needed to make in order to get
genmake2 to run without warnings and the model to compile:

*1.* Set the environment variable NETCDF_ROOT.  That's fine.

*2.* In the optfile, add '-l netcdf' to the line:
       LIBS="-L${NETCDF_ROOT}/lib -l netcdf"
I would have thought everyone would have needed that.
(I used linux_amd64_gfortran, but we see that, e.g. linux_ia64_ifort would
have required a similar edit.

*3.* After getting my Makefile, I needed to add the include path to my MPI
headers:
       INCLUDES =
-I/gpfs/cluster/geog/ggdagw/netcdf/4.0/gnu_fc_4.1.2/include
-I/usr/mpi/gcc/openmpi-1.4.2-
qlc/include
so that make depend would not give a warning about not finding "mpif.h"

*4.* Then I could compile cleanly--without fixing (3), I'd get a compile
error.

Thanks in advance for your help/comments.
Cheers,
Fanny
