Interfaces

  • ParMetis

    • Works directly on structure of distributed sparse matrix

    • Computes block_migration object, e.g. block_migration m= parmetis_migration(A);

    • Can be used to migrate A and other matrices and vectors

    • Partioning and migration can be performed in one statement:

      Matrix B(A, p parmetis_migration(A)); That creates B directly from the partitioning

  • Topomap

    • Library by Torsten Höfler to map distributed application optimally to topology of used parallel computer

    • Most general existing approach that handles arbitrary graph topologies in the application and arbitrary topologies in the computer network
