- Divide world up into geometric domains as usual (Figure FEM 9)

- Information (triangles with i,j as an edge) to calculate
can involve 
processors (four is most in
two-dimensional example), but communication is local.
- This is called assembly.
- Each processor should know
and 
for all j
connected to each i ``owned'' by processor.
