Hi Justin, Ah yes. I saw something like this when attempting to set up travis. The problem appears to be that the dependency analysis in pip is broken so it doesn't realise it has to build and install Cython before it builds h5py. I think the workaround is to force Cython installation in the install script before looking at the requirements file. I will push a branch presently and merge it as soon as it passes tests.

Hi David

Thanks for the updated script. So I am using the system provided openmpi/1.8.3 module but built my own Python 2.7.10 and pip from source. I am getting an error as shown in the attached firedrake-install.log

I also got a similar issue when I built my own openmpi library, although in that case I didn’t have the cython related errors and only had the ones related to hdf5/h5py

Any idea what this is?

Thanks, Justin

The branch is merged now so I believe this is now fixed.

It turns out that this is for the usual reason: I am an idiot. A fix for this is in the further-install-fixes branch and I will merge the branch as soon as tests pass.

(What's actually going on is that I am abusing CalledProcessError when I should really raise a special exception for this case. I have now created a new exception and raised that instead).

Cheers,

Thanks David,

I actually forgot about the --no_package_manager option. But when I tried installing with it, i get this error:

$ python firedrake-install --no_package_manager Traceback (most recent call last): File "firedrake-install", line 265, in <module> raise subprocess.CalledProcessError TypeError: __init__() takes at least 3 arguments (1 given)

Even if I add the --disable_ssh and --developer tags I get the above error. Am I suppose to do something else with this?

Thanks, Justin

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

Added and currently testing.

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?

Also added. Thanks for catching this.

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?

And this.

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?

Ah yes. Fecking swig. I've added the dependency to the new branch. Hopefully the swig dependency is going away very soon.

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.

I think (c) is the case right now. If you run the script on a non-Ubuntu system or pass the --no_package_manager option then it will just assume that you have installed the dependencies somewhere visible and will get on with pip.

I think (b) is [a] hard and [b] in the case of MPI probably a bad idea. Supercomputers are such a diverse bunch of hacked up distributions that I think that installing the compiled dependencies automatically in a way which is portable would require a lot of install script work. In the case of MPI, you really need to use the MPI build which talks to the fast interconnect on your supercomputer, so automatically building vanilla OpenMPI is a Bad Thing.

Cheers,

David

Thanks, Justin

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?)
