Member Function Documentation

◆ begin()

virtual const_iterator TiledArray::detail::BlockedPmap::begin ( ) const

inlinevirtual

Begin local element iterator.

Returns: An iterator that points to the beginning of the local element set

Reimplemented from TiledArray::Pmap.

Definition at line 95 of file blocked_pmap.h.

◆ end()

virtual const_iterator TiledArray::detail::BlockedPmap::end ( ) const

inlinevirtual

End local element iterator.

Returns: An iterator that points to the beginning of the local element set

Reimplemented from TiledArray::Pmap.

Definition at line 98 of file blocked_pmap.h.

◆ is_local()

virtual bool TiledArray::detail::BlockedPmap::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 91 of file blocked_pmap.h.

◆ owner()

virtual size_type TiledArray::detail::BlockedPmap::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.

Definition at line 79 of file blocked_pmap.h.
