MatSTRUMPACKReordering

sparsity reducing ordering to be used in MATSOLVERSTRUMPACK

Synopsis

typedef enum {
  MAT_STRUMPACK_NATURAL,
  MAT_STRUMPACK_METIS,
  MAT_STRUMPACK_PARMETIS,
  MAT_STRUMPACK_SCOTCH,
  MAT_STRUMPACK_PTSCOTCH,
  MAT_STRUMPACK_RCM,
  MAT_STRUMPACK_GEOMETRIC,
  MAT_STRUMPACK_AMD,
  MAT_STRUMPACK_MMD,
  MAT_STRUMPACK_AND,
  MAT_STRUMPACK_MLF,
  MAT_STRUMPACK_SPECTRAL
} MatSTRUMPACKReordering;

Values

• MAT_STRUMPACK_NATURAL - use the current ordering

• MAT_STRUMPACK_METIS - use MeTis to compute an ordering

• MAT_STRUMPACK_PARMETIS - use ParMeTis to compute an ordering

• MAT_STRUMPACK_SCOTCH - use Scotch to compute an ordering

• MAT_STRUMPACK_PTSCOTCH - use parallel Scotch to compute an ordering

• MAT_STRUMPACK_RCM - use an RCM ordering

• MAT_STRUMPACK_GEOMETRIC - use a geometric ordering (needs mesh info from user)

• MAT_STRUMPACK_AMD - approximate minimum degree

• MAT_STRUMPACK_MMD - multiple minimum degree

• MAT_STRUMPACK_AND - approximate nested dissection

• MAT_STRUMPACK_MLF - minimum local fill

• MAT_STRUMPACK_SPECTRAL - spectral nested dissection
