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

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
