Re: [HG dolfin] Use DofMap in FEM to get dof mapping and to compute number of nonzeroes per matrix row. This gives big memory savings for some problems. For /src/demo/pde/elasticity memory use was approx. 600mb, now 200mb.

Do you mean "DofMap associated with mesh and finite element"?

Yep.

I'm ok with that. We could have a DiscreteFunction with two members:

    Vector
    DofMap

That would work.

ok. This will also have consequences for the file format for
input/output of Functions.

Yes. Slightly related, I'd like to add output for MeshFuction<T> if theT is suitable for output.


This is already supported. (Fixed by Ola last week.)

It has been implemented for T = int, real, bool, but we need to add
support for uint as well.

Great. I was think more about exporting to VTK format in order tovisualise, for example, the mesh partition.
