MPPTScotchStrategyType

Pre-defined strategy used by MATPARTITIONINGPTSCOTCH when delegating to the PT-Scotch library

Synopsis

typedef enum {
  MP_PTSCOTCH_DEFAULT,
  MP_PTSCOTCH_QUALITY,
  MP_PTSCOTCH_SPEED,
  MP_PTSCOTCH_BALANCE,
  MP_PTSCOTCH_SAFETY,
  MP_PTSCOTCH_SCALABILITY
} MPPTScotchStrategyType;

Values

• MP_PTSCOTCH_DEFAULT - the default PT-Scotch strategy

• MP_PTSCOTCH_QUALITY - focus on partition quality at the expense of time

• MP_PTSCOTCH_SPEED - focus on time to compute the partition

• MP_PTSCOTCH_BALANCE - favor load balance

• MP_PTSCOTCH_SAFETY - use the most reliable internal heuristics

• MP_PTSCOTCH_SCALABILITY - favor scalability at large process counts
