MPChacoGlobalType#

Global partitioning method used by MATPARTITIONINGCHACO when delegating to the Chaco library

Synopsis#

typedef enum {
  MP_CHACO_MULTILEVEL = 1,
  MP_CHACO_SPECTRAL   = 2,
  MP_CHACO_LINEAR     = 4,
  MP_CHACO_RANDOM     = 5,
  MP_CHACO_SCATTERED  = 6
} MPChacoGlobalType;

Values#

MP_CHACO_MULTILEVEL - multilevel-Kernighan–Lin style partitioning
MP_CHACO_SPECTRAL - spectral partitioning using Lanczos or RQI eigensolvers
MP_CHACO_LINEAR - linear (rank-order) initial partition
MP_CHACO_RANDOM - random initial partition
MP_CHACO_SCATTERED - scattered (round-robin) initial partition
