Abstract
This document describes the capabilities and operations of Scotch and
libScotch , a software package and a software library devoted to static
mapping, partitioning, and sparse matrix block ordering of graphs and
meshes/hypergraphs. It gives brief descriptions of the algorithms, details
the input/output formats, instructions for use, installation procedures, and
provides a number of examples.
Scotch is distributed as free/libre software, and has been designed such
that new partitioning or ordering methods can be added in a straightforward
manner. It can therefore be used as a testbed for the easy and quick coding
and testing of such new methods, and may also be redistributed, as a library,
along with third-party software that makes use of it, either in its original or
in updated forms.
