compiling OpenMPI & HDF5 with Fortran support
Fortran…why on Earth would I want something with Fortran support?
Apparently it’s fast; and when something is fast people still use it.
I’m currently looking into the radiative transfer code
Hyperion and it requires both MPI
and HDF5 to be compiled with fortran support. It’s fairly simple to
do, but can be a pain in the neck to find the
syntax if you
don’t know exactly where to look. Let’s start with
OpenMPI which is currently on version
1.6.5.
?> ./configure --prefix=/Users/bob/local/openmpi-1.6.5 F77=gfortran FC=gfortran
?> make
?> make install
For HDF5 the syntax is similar:
?> ./configure CC=mpicc --enable-fortran --enable-hl --prefix=/Users/bob/local/hdf5-1.8.11 FC=gfortran
?> make
?> make install
And that should do it. To get hyperion to see these you just add
the /bin dirs to your $PATH and the lib dirs to your
$LD_LIBRARY_PATH. To check if the MPI-fortran bindings worked you
can type mpif90 and mpi77 at the terminal and gfortran should error
out saying that there are no input files.
Lastly once you recompile OpenMPI you may have to
reconfigure/recompile/reinstall mpi4py
if you’re using it. This is also super simple, but on OSX it can be
troublesome. Before the compilation you have to redirect it to the
proper SDK directory; the install should look like so:
?> export SDKROOT=/
?> python setup.py build
?> python setup.py install
I usually end up with an error at the end, but it installs and seems
to run without any problems.
