SCOTCH is a project carried out within the Satanas team of the Laboratoire Bordelais de Recherche en Informatique (LaBRI). It is part of the ScAlApplix project of INRIA Bordeaux - Sud-Ouest.
Its purpose is to apply graph theory, with a divide and conquer approach, to scientific computing problems such as graph and mesh partitioning, static mapping, and sparse matrix ordering, in application domains ranging from structural mechanics to operating systems or bio-chemistry.
The SCOTCH distribution is a set of programs and libraries which implement the static mapping and sparse matrix reordering algorithms developed within the SCOTCH project.
