\maketitle

\begin{abstract}
This document describes the capabilities and operations of
\scotch\ and \libscotch, a software package and a software library
devoted to static mapping, edge- and vertex-based graph 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.

\section*{Credits}

I wish to thank all of the following people:
\begin{itemize}
\item
Patrick Amestoy collaborated to the design of the Halo Approximate
Minimum Degree algorithm~\cite{peroam99} that had been embedded into
\scotch\ \textsc{3.3}, and provided versions of his Approximate Minimum
Degree algorithm, available since version \textsc{3.2}, and of his
Halo Approximate Minimum Fill algorithm, available since version
\textsc{3.4}. He designed the mesh versions of the approximate
minimum degree and approximate minimum fill algorithms, which are
available since version \textsc{4.0};
\item
S\'ebastien Fourestier coded the mapping with fixed vertices,
remapping, and remapping with fixed vertices sequential routines that
are available since version \textsc{6.0};
\item
Marc Fuentes designed the mesh-to-dual-graph routines, extended the
functional scope of the \metis\ compatibility library, and coded CMake
environment files;
\item
Jun-Ho Her coded the graph partitioning with overlap routines that
were introduced in the unpublished \textsc{5.2} release, subsequently
publicly released in version \textsc{6.0};
\item
Amaury Jacques improved the development environment and contributed to
the consistency checking and non-regression testing routines;
\item
C\'edric Lachat contributed to the robustness of the software, in
relation with his development of the \textsc{PaMPA} software;
\item
Alex Pothen kindly provided a version of his Multiple Minimum Degree
algorithm, which was embedded into \scotch\ from version \textsc{3.2} to
version \textsc{3.4};
\item
Florent Pruvost set up the continuous integration environment on
Inria GitLab;
\item
Luca Scarano coded the multilevel graph algorithm in
\scotch\ \textsc{3.1};
\item
Yves Secretan contributed to the \textsc{MinGW32} port;
\item
David Sherman proofread version \textsc{3.2} of this manual.
\end{itemize}
