Nested dissection by METIS/ParMETISThese methods produce orderings for various applications (e.g., reducing fill in sparse matrix factorizations). Ordering is accessed through calls to Zoltan_Order.
Nested dissection by Scotch/PT-Scotch
Local ordering with Hilbert space filling curves
|ORDER_METHOD||The order algorithm used by Zoltan is specified by this parameter.
Valid values are
"METIS" (sequential nodal nested dissection by METIS),
|ORDER_METHOD = PARMETIS (with MPI), METIS (when no MPI)|
