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.

Hi All,
I have a branch going through testing now which will handle PETSC_CONFIGURE_OPTIONS in a smarter way. Basically we'll just make sure that the things which are required are there, and we'll also honour anything the user has already set. I've also updated docs to say that that's what happens.
I am also open to the suggestion that we could add more configuration options to the default set. Would anyone like to suggest what they should be?
I think --download-hypre=1 at least. Maybe also a sparse direct solver (mumps?) which I think needs --download-metis --download-parmetis --download-mumps (maybe some others?)
