Could you share some pointers on how you have set up your build, which
versions of packages (MPICH or OpenMPI), which BLAS, version numbers
etc and I can try to replicate and think about whether this can be
documented as part of Dorsal or somewhere else.

I'm referring to having a good build of the FEniCS software stack on a
standard desktop or laptop running the latest Ubuntu which is what
most of us have. I've been relying on Dorsal which tries to use as
many Debian packages as possible, but apparently that is not enough.
