[firedrake] The wonderful world of firedrake-install

[Justin Chang]

I agree that hype and a sparse direct solver like mumps is necessary.
The latter needs --download-metis --download-parmetis
--download-scalapack.

More comments:

4) If mumps is to be included, the install script has to ensure that
one has cmake >=2.5 when configuring metis, otherwise PETSc configure
will return an error. Perhaps include "brew install cmake" and "sudo
apt-get install cmake" in the script?

5) Should --download-exodusii (and it's dependencies --download-netcdf
--download-hdf5) also be included in the PETSC_CONFIGURE_OPTIONS? I
imagine that if one wants to solve problems on large-scale
unstructured grids, .exo files would be more feasible to use over .msh
files. Or is exodusii already accounted for in firedrake/PyOP2/etc?

6) If I run the script on a pristine MacOSX, I get an error saying
"OSError: Unable to find SWIG installation. Please install SWIG
version 2.0.0 or higher." I am guessing "brew install swig" was
somehow missed in the firedrake-install script?

7) Perhaps not as important, but do y'all think it's possible to make
this script more non-Ubuntu HPC system friendly? For isntance, either
a) require the user to install his or her own local OpenMPI and Python
libraries from source, b) let script download the tarballs/git
repositories remotely and install it for you (kind of like how PETSc
handles external packages through --download-<package>), or c) enable
the user to point to the system provided OpenMPI and Python libraries.
Same would need to be done for CMake, SWIG, and PCRE as these packages
cannot simply be obtained from pip.

Thanks,
Justin
