Instructions on how to build FEniCS with MPI support

[Bruno Mundim]

Hi,

I am trying to evaluate the feasibility of building and running FEniCS

on our cluster, but I am having trouble to find specific instructions

on how to compile it from source with MPI support. I would appreciate

if you could point me to the right documentation.

Thanks,

Bruno.

See https://fenicsproject.org/download/. Python packages are built
using standard procedures. Building of DOLFIN is more complicated and
described in detail at
https://fenics.readthedocs.io/projects/dolfin/en/latest/installation.html.

Hi Bruno,

The Dockerfiles https://bitbucket.org/fenics-project/docker/src
provide a reasonable 'living' set of instructions on what dependencies
are required to build the complete FEniCS stack, and how to compile
FEniCS itself. We've produced something that works on Redhat-type
systems by straightforward inspection and translation of these files.

You could also take a look at my own scripts for our cluster. They are
deliberately rough and ready for transparency, but they do the job:

https://bitbucket.org/unilucompmech/fenics-gaia-cluster/overview

Because of the out of date software on our cluster I compile
everything except the compiler and Python.

However, if you have a reasonably complete and up-to-date modules
system on your cluster I would advise pulling in compilers and as many
libraries as possible (Boost, MPI, HDF5, Python, BLAS, Eigen etc.)
from there and then compiling your own PETSc (see dev-env/Dockerfile
for good options), SLEPc, then building the FEniCS Python packages
(instant, dijitso, ffc, fiat) and then finally DOLFIN.

Not forgetting the FEniCS Python package UFL, of course!
