◆ Exec

template<class Real >

◆ exchange()

template<class Real >
void peclet::voro::fv::GhostExchange< Real >::exchange ( const DV< Real > &  f,
int  nc 
) const
inline

Refresh the ghost entries [nOwned, nOwned + nGhost) of an nc-component cell field.

◆ exchangeHost()

template<class Real >
void peclet::voro::fv::GhostExchange< Real >::exchangeHost ( const DV< Real > &  f,
int  nc 
) const
inline

The host reference path: VoronoiHalo::forward per component through a host mirror.

◆ init()

template<class Real >
void peclet::voro::fv::GhostExchange< Real >::init ( peclet::voro::mpi::VoronoiHalo< Real > &  h,
int  owned 
)
inline

◆ max()

template<class Real >
Real peclet::voro::fv::GhostExchange< Real >::max ( Real  v) const
inline

◆ sum()

template<class Real >
Real peclet::voro::fv::GhostExchange< Real >::sum ( Real  v) const
inline

Member Data Documentation

◆ devicePack

template<class Real >
bool peclet::voro::fv::GhostExchange< Real >::devicePack = true

Device-packed path (default): the sends are gathered on the device from the flat topology's index list into one buffer, only the packed send/recv buffers cross to the host for MPI, and the receives land in the ghost slots by a device scatter — no whole-field round trip. The host path (devicePack = false, VoronoiHalo::forward per component) is the reference; the two are gated bitwise-equal in tests/kokkos_mpi/test_flow_mpi.
