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 fillreducing ordering for direct solvers. Currently Zoltan relies on thirdparty libraries (ParMetis and PTScotch) for this.
