  • registering preconditioners Solves a linear system in parallel with KSP.
    Input parameters include:
    -m <mesh_x> : number of mesh points in x-direction
    -n <mesh_n> : number of mesh points in y-direction
  • setting a user-defined shell preconditioner Solves a linear system in parallel with KSP. Also
    illustrates setting a user-defined shell preconditioner and using the
    macro __FUNCT__ to define routine names for use in error handling.
    Input parameters include:
    -user_defined_pc : Activate a user-defined preconditioner
  • setting a user-defined shell preconditioner
    Solves a linear system in parallel with KSP. Also indicates
    use of a user-provided preconditioner. Input parameters include:
    -user_defined_pc : Activate a user-defined preconditioner

    Program usage: mpiexec ex15f [-help] [all PETSc options]
