virtual part_t Zoltan2::Machine< pcoord_t, part_t >::getNumUniqueGroups ( ) const

inlinevirtual

getNumUniqueGroups function return the number of unique Dragonfly network groups in provided allocation.

Equals the length of group_count member data, if available, otherwise we consider the whole allocation to be one group.

Reimplemented in Zoltan2::MachineDragonflyRCA< pcoord_t, part_t >, and Zoltan2::MachineDragonflyRCAForTesting< pcoord_t, part_t >.

virtual bool Zoltan2::Machine< pcoord_t, part_t >::getGroupCount ( part_t * grp_count ) const

inlinevirtual

getGroupCount function return the number of ranks in each group (RCA X-dim, e.g. first dim)

Ex, 4 ranks with coord (3, 1, 1) and 8 ranks with coord (5, 2, 4), will produce grp_count = [0, 0, 0, 4, 0, 8, 0, ...] which is trimmed and returned as grp_count = [4, 8]

(Currently only for Zoltan2_MachineDragonflyRCA, and used for MultiJagged's first cut in "algorithms/partition/Zoltan2_TaskMapper.hpp" thru "problems/Zoltan2_MappingProblem.hpp". return true if group_count is available
