New question #119471 on DOLFIN:
https://answers.launchpad.net/dolfin/+question/119471

when running the elasticity demo script in parallel, with:
mpirun -np 2 python demo.py

I get the parallel solve & desired results on my Ubuntu installation, but the following error on my RHEL installation.

cpp.VariationalProblem.solve(self, u)
RuntimeError: *** Error: No suitable solver for parallel LU. Consider configuring PETSc with MUMPS or SPOOLES. 

I must mention that during the RHEL installation I skipped trilinos, cgal and scotch packages.

Not sure if this is a dolfin/petsc parallel implementation issue or something specific to my RHEL installation.
