dg in parallel

Asked by Lyuda Vynnytska on 2013-01-23

Hi,
Running demo_dg_advection_diffusion.py from undocumented with mpirun produces the following:
 Error: Unable to perform operation in parallel.
*** Reason: Assembly over interior facets is not yet working in parallel.
*** Consider filing a bug report at https://bugs.launchpad.net/dolfin.
Does it mean that DG doesn't work in parallel?
