Re: degree of freedom numbering

 

I just started this morning. I have the mesh partitioned (using METIS), and a MeshFunction contains the partition number for each cell. I plan initially to let each processor have a copy of the entire mesh and just assemble its partition. Distributing the mesh will come later.

Excellent! I have an MSc student starting after Christmas to work on
parallelization of the mesh data structures, including partitioning.
We should try to coordinate the effort.

OK. I'm working on parallel assembly now, so I'll take a look at the degree of freedom numbering when I get to assembling vector-valued problems.

I'll check in the beginnings of parallel assembly after the new release is made.

Sounds good. This is the natural way I think.

Should we consider changing the degree of freedom numbering such that
degrees of freedom at a node are located next to each other in the
matrix/vector? This will be needed for parallel assembly. It may also
speed up the assembly of sparse matrices by allowing blocks to be
assembled.
