|void||Isorropia::Epetra::Orderer::order (bool force_ordering=false)|
|Method which does the work of computing a new ordering. |
Here we describe the ordering interface provided by Isorropia.
Isorropia currently supports a subset of the graph (sparse matrix) ordering features in Zoltan. The intended main use is to produce a permutation that can be used as fill-reducing ordering for direct solvers. Currently Zoltan relies on third-party libraries (ParMetis and PT-Scotch) for this.
