Hi all,

Connected to this discussion is also the msc thesis work on dolfin
parallization of Nicklas Jansson at KTH. He has now started working on
this based on the updated TODO list of dolfin. He has tried to send an
email to this list (dolfin-dev@xxxxxxxxxx) but it appears that it is stuck
in a filter awaiting moderator approval. Maybe someone (a moderator) could
help out so that we can get past this, to better coordinate
parallelization efforts?

Thanks!

/Johan
