PTScotch domain decomposition. For the main details about how to define the strategies, see scotchDecomp.
Nonetheless, when decomposing in parallel, using writeGraph=true
will write out .dgr files for debugging. For example, use these files with
dgpart
as follows:
mpirun -np 4 dgpart 2 'region0_%r.dgr'
