Detailed Description

Kokkos-compatible real-attribute packing functor.

Note

The current MPI execution path performs equivalent packing on host.

Constructor & Destructor Documentation

PackSendBufferFunctor() [1/2]

orb5x::PackSendBufferFunctor::PackSendBufferFunctor ( Kokkos::View< Real **, Kokkos::LayoutStride >  arr_, Kokkos::View< int * >  iphole_, Kokkos::View< int * >  sdispl_, Kokkos::View< Real * >  sbuf_, int  natts_, int  npmax_  )

inline

Construct a marker-major packing operation.

Parameters

[in]	arr_	Source matrix indexed as [marker][attribute].
[in]	iphole_	Ordered local marker indices to send.
[in]	sdispl_	Destination displacements retained by the migration plan.
[out]	sbuf_	Contiguous packed send buffer.
[in]	natts_	Number of attributes per marker.
[in]	npmax_	Allocated particle stride (unused for marker-major storage).

PackSendBufferFunctor() [2/2]

orb5x::PackSendBufferFunctor::PackSendBufferFunctor ( Kokkos::View< Real * >  arr_, Kokkos::View< int * >  iphole_, Kokkos::View< int * >  sdispl_, Kokkos::View< Real * >  sbuf_, int  natts_, int  npmax_  )

inline

Construct an attribute-major packing operation.

Parameters

[in]	arr_	Flattened source indexed as attribute*npmax + marker.
[in]	iphole_	Ordered local marker indices to send.
[in]	sdispl_	Destination displacements retained by the migration plan.
[out]	sbuf_	Contiguous packed send buffer.
[in]	natts_	Number of attributes per marker.
[in]	npmax_	Allocated particle stride in the flattened source.
