Detailed Description

template<int Dim>
class peclet::core::halo::ParticleMigratorView< Dim >

Device counterpart of ParticleMigrator.

Particles live in flat device Views: pos is (capacity·Dim) particle-major (pos(i·Dim+d)), payload is (capacity·stride) opaque bytes. migrate() rewrites [0, newCount) in place and returns the new local count.

migrate()

Index peclet::core::halo::ParticleMigratorView< Dim >::migrate ( View< double >  pos, View< char >  payload, Index  n, std::size_t  stride  )

inline

Reassign every particle (i ∈ [0,n)) to its owning rank, in place.

Returns the new local count (≤ pos.extent(0)/Dim). Caller must size the Views for the worst-case arrival count.
