Detailed Description

template<class LocalOrdinal, class GlobalOrdinal, class DeviceType>
class Tpetra::Details::LocalMap< LocalOrdinal, GlobalOrdinal, DeviceType >

"Local" part of Map suitable for Kokkos kernels.

Warning
This object's interface is not yet fixed. We provide this object currently only as a service to advanced users.

The "local" Map is suitable for use in Kokkos parallel operations in the Map's native execution space, which is Map::device_type::execution_space.

By "local," we mean that the object performs no MPI communication, and can only access information that would never need MPI communication, no matter what kind of Map this is.

Constructor & Destructor Documentation

template<class LocalOrdinal, class GlobalOrdinal, class DeviceType>
KOKKOS_DEFAULTED_FUNCTION Tpetra::Details::LocalMap< LocalOrdinal, GlobalOrdinal, DeviceType >::LocalMap ( )
default

Default constructor.

Member Function Documentation

template<class LocalOrdinal, class GlobalOrdinal, class DeviceType>
KOKKOS_INLINE_FUNCTION LocalOrdinal Tpetra::Details::LocalMap< LocalOrdinal, GlobalOrdinal, DeviceType >::getLocalNumElements ( ) const
inline

The number of indices that live on the calling process.

Definition at line 80 of file Tpetra_Details_LocalMap.hpp.

template<class LocalOrdinal, class GlobalOrdinal, class DeviceType>
KOKKOS_INLINE_FUNCTION GlobalOrdinal Tpetra::Details::LocalMap< LocalOrdinal, GlobalOrdinal, DeviceType >::getIndexBase ( ) const
inline

Definition at line 85 of file Tpetra_Details_LocalMap.hpp.

template<class LocalOrdinal, class GlobalOrdinal, class DeviceType>
KOKKOS_INLINE_FUNCTION bool Tpetra::Details::LocalMap< LocalOrdinal, GlobalOrdinal, DeviceType >::isContiguous ( ) const
inline

Whether the Map is (locally) contiguous.

This is conservative; a Map is "contiguous" if and only if it is stored that way.
