Member Typedef Documentation

◆ size_type

typedef Pmap::size_type TiledArray::detail::HashPmap::size_type

Size type.

Definition at line 46 of file hash_pmap.h.

Constructor & Destructor Documentation

◆ HashPmap()

TiledArray::detail::HashPmap::HashPmap	(	World &	world,
		const size_type	size,
		madness::hashT	seed = `0ul`
	)

inline

Construct a hashed process map.

Parameters

world	The world where the tiles are mapped
size	The number of tiles to be mapped
seed	The hash seed used to generate different maps

Definition at line 53 of file hash_pmap.h.

◆ ~HashPmap()

virtual TiledArray::detail::HashPmap::~HashPmap ( )

inlinevirtual

Definition at line 56 of file hash_pmap.h.

Member Function Documentation

◆ is_local()

virtual bool TiledArray::detail::HashPmap::is_local ( const size_type tile ) const

inlinevirtual

Check that the tile is owned by this process.

Parameters

tile	The tile to be checked

Returns: true if tile is owned by this process, otherwise false .

Implements TiledArray::Pmap.

Definition at line 73 of file hash_pmap.h.

Here is the call graph for this function:

◆ known_local_size()

virtual bool TiledArray::detail::HashPmap::known_local_size ( ) const

inlinevirtual

Queries whether local size is known.

Returns: true if the number of local elements is known

Note: Override if it is too expensive to precompute

Reimplemented from TiledArray::Pmap.

Definition at line 77 of file hash_pmap.h.

◆ owner()

virtual size_type TiledArray::detail::HashPmap::owner ( const size_type tile ) const

inlinevirtual

Maps tile to the processor that owns it.

Parameters

tile	The tile to be queried

Returns: Processor that logically owns tile

Implements TiledArray::Pmap.
