Subject: [Scotch-announces] Scotch 5.1.12 is out!
Message-ID: <4E5ED6BC.5030804@labri.fr>


We announce the  release, as libre/free software, of  revision 5.1.12 of the
SCOTCH  and  PT-SCOTCH  software  package  and  library  for  sequential and
parallel  graph  partitioning,  sequential  and parallel  graph  clustering,
sequential mesh/hypergraph  partitioning and static  mapping, and sequential
and parallel sparse matrix block ordering.


Important new features
======================

- The  clustering  capabilities of  Scotch and  PT-Scotch are  now available
   from the  command line  programs. Strategy string building helper routines
   are also available in the libScotch library for clustering.

- Some internal graph handling routines  have been exposed in the interface,
   such  as  for  graph  coarsening.  This  may  allow   people  working with
   unstructured meshes to  implement multi-level  mesh computations  directly
   by taking advantage of the  distributed graph coarsening and data exchange
   (halo) routines provided by the libScotch.

- Load  balance  enforcement  has  been  improved  much for  parallel  graph
   partitioning.

Sequential graph repartitioning  and remapping will be available in the next
5.2  release.  Parallel  static mapping  and  parallel  direct  k-way  graph
partitioning will be available in release 5.3.


How to get SCOTCH
=================

Scotch can be freely  downloaded, under  the terms of the  CeCILL-C license.
