Detailed Description

template<class Real, int MAXP = kMaxPlanes, int MAXT = kMaxTriangles, class Sdf = NoSdf>
struct peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT, Sdf >

Sdf (rung A0): an SDF solid provider, replicated on every rank (set it with setSdf() before establish()); the owned cells are clipped and boundary-watched exactly as in the single-domain MovingTessellation. Default NoSdf leaves the driver unchanged.

◆ Mem

template<class Real , int MAXP = kMaxPlanes, int MAXT = kMaxTriangles, class Sdf = NoSdf>
using peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT, Sdf >::Mem = typename Kokkos::DefaultExecutionSpace::memory_space

◆ Vec3

template<class Real , int MAXP = kMaxPlanes, int MAXT = kMaxTriangles, class Sdf = NoSdf>
using peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT, Sdf >::Vec3 = std::array<Real, 3>

Member Function Documentation

◆ combinedGid()

template<class Real , int MAXP = kMaxPlanes, int MAXT = kMaxTriangles, class Sdf = NoSdf>
const std::vector< long > & peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT, Sdf >::combinedGid ( ) const
inline

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

◆ establish()

template<class Real , int MAXP = kMaxPlanes, int MAXT = kMaxTriangles, class Sdf = NoSdf>
void peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT, Sdf >::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 = kMaxPlanes, int MAXT = kMaxTriangles, class Sdf = NoSdf>
void peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT, Sdf >::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 = kMaxPlanes, int MAXT = kMaxTriangles, class Sdf = NoSdf>
int peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT, Sdf >::nCombined ( ) const
inline

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

◆ nOwned()

template<class Real , int MAXP = kMaxPlanes, int MAXT = kMaxTriangles, class Sdf = NoSdf>
int peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT, Sdf >::nOwned ( ) const
inline

◆ numRegathers()

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

◆ positions()

template<class Real , int MAXP = kMaxPlanes, int MAXT = kMaxTriangles, class Sdf = NoSdf>
const Kokkos::View< Real *, Mem > & peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT, Sdf >::positions ( ) const

◆ sdf()

template<class Real , int MAXP = kMaxPlanes, int MAXT = kMaxTriangles, class Sdf = NoSdf>

void peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT, Sdf >::setProfile ( bool  on)
inline

Wall re-gather policy forwarded to the local tessellation (see MovingTessellation::wallExact). The cold build's timing / over-buffer report on stderr (MovingTessellation::profile).

◆ setSdf()

template<class Real , int MAXP = kMaxPlanes, int MAXT = kMaxTriangles, class Sdf = NoSdf>
void peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT, Sdf >::setSdf ( const Sdf &  s)
inline

Replicated SDF geometry (every rank holds the same provider). Call before establish().

◆ setWallMode()

template<class Real , int MAXP = kMaxPlanes, int MAXT = kMaxTriangles, class Sdf = NoSdf>
void peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT, Sdf >::setWallMode ( bool  exact,
Real  skin = Real(0)

StepStats peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT, Sdf >::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 = kMaxPlanes, int MAXT = kMaxTriangles, class Sdf = NoSdf>
MovingTessellation< Real, MAXP, MAXT, false, Sdf > & peclet::voro::mpi::DistributedMovingTessellation< Real, MAXP, MAXT, Sdf >::tess ( )
inline

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