We announce the release, as libre/free software, of revision 5.1 of the
SCOTCH and PT-SCOTCH software package and library for sequential and
parallel graph partitioning, sequential mesh/hypergraph partitioning and
static mapping, and sequential and parallel sparse matrix block ordering.
PT-Scotch now provides an interface for parallel graph partitioning and
static mapping. At the time being, target architectures other than complete
graphs, whether weighted or not, are not taken into account, such that only
parallel graph partitioning is available, not full parallel static mapping.
Parallel static mapping will be available in a future release.
Parallel graph partitioning is performed to date by the means of recursive
parallel graph bipartitioning, not direct k-way partitioning. PT-Scotch is
therefore slower than direct parallel k-way partitioners, yet yields high
What is SCOTCH
SCOTCH is a project carried out at the Laboratoire Bordelais de Recherche en
Informatique (LaBRI) of the Universite Bordeaux I.
It is part of project ScAlApplix of INRIA Bordeaux - Sud-Ouest. Its goal is
to apply graph theory, with a ``divide and conquer'' approach, to scientific
computing problems such as graph partitioning, static mapping, and sparse
How to get SCOTCH
Scotch can be freely downloaded, under the terms of the CeCILL-C license.
