MatSTRUMPACKReordering

sparsity reducing ordering to be used in `MATSOLVERSTRUMPACK``

Synopsis

typedef enum {
  MAT_STRUMPACK_NATURAL  = 0,
  MAT_STRUMPACK_METIS    = 1,
  MAT_STRUMPACK_PARMETIS = 2,
  MAT_STRUMPACK_SCOTCH   = 3,
  MAT_STRUMPACK_PTSCOTCH = 4,
  MAT_STRUMPACK_RCM      = 5
} 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
