Detailed Description

Owning MPI rank of each box, indexed by GLOBAL box index (parallel to a BoxArray).

Metadata replicated on every rank.

EXPLICIT assignment: rank[i] = owning rank of box i (move).

For external balanced strategies (load_balance.hpp).

int pops::DistributionMapping::operator[] ( int i ) const

inline

Owning rank of the box with global index i.

const std::vector< int > & pops::DistributionMapping::ranks ( ) const

inline

View on the rank vector (element-by-element equality = same assignment).

Here is the caller graph for this function:
