Member Function Documentation

combinedGid()

template<class Real , int MAXP = 64, int MAXT = 112>

const std::vector< long > & peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT >::combinedGid ( ) const

inline

Global ids of the combined (owned+ghost) seeds after the last (re)gather.

establish()

template<class Real , int MAXP = 64, int MAXT = 112>

void peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT >::establish ( const std::vector< Vec3 > &  ownedPos, const std::vector< long > &  ownedGid, const std::vector< Real > &  ownedW  )

inline

Establish the tessellation from this rank's owned seeds (collective). Call once after init and whenever ownership changes externally (e.g. after a rebalance/migration).

init()

template<class Real , int MAXP = 64, int MAXT = 112>

void peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT >::init ( std::array< Real, 3 >  origin, std::array< Real, 3 >  size, std::array< long, 3 >  gsize, std::array< bool, 3 >  periodic, Real  rcut, Real  skin, Real  tol, MPI_Comm  comm, int  searchWindow = 4, int  densityCount = -1  )

inline

One-time setup. gsize is the ORB decomposition granularity (cells per axis).

nCombined()

template<class Real , int MAXP = 64, int MAXT = 112>

int peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT >::nCombined ( ) const

inline

Combined owned+ghost count and owned count of the current tessellation.

nOwned()

template<class Real , int MAXP = 64, int MAXT = 112>

int peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT >::nOwned ( ) const

inline

numRegathers()

template<class Real , int MAXP = 64, int MAXT = 112>

long peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT >::numRegathers ( ) const

inline

ownerOf()

template<class Real , int MAXP = 64, int MAXT = 112>

int peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT >::ownerOf ( const Vec3 &  x ) const

inline

positions()

template<class Real , int MAXP = 64, int MAXT = 112>

const Kokkos::View< Real *, Mem > & peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT >::positions ( ) const

inline

step()

template<class Real , int MAXP = 64, int MAXT = 112>

StepStats peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT >::step ( const std::vector< Vec3 > &  ownedPos )

inline

Advance to new owned positions (same ownership as establish; collective every step).

tess()

template<class Real , int MAXP = 64, int MAXT = 112>

MovingTessellation< Real, MAXP, MAXT > & peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT >::tess ( )

inline

The device tessellation (cells [0, nOwned) are this rank's owned cells).
