Detailed Description

template<typename Partition, typename Mapper>
class stapl::directory_impl::manager< Partition, Mapper >

A directory's manager maps GIDs to locations that are responsible for knowing exact locality about that GID. The result of this mapping is not necessarily the actual locality of the element. This manager uses the partition and mapper information to perform the translation.

Template Parameters

Partition	The container's partition
Mapper	The container's mapper

Constructor & Destructor Documentation

manager() [1/2]

template<typename Partition, typename Mapper>

stapl::directory_impl::manager< Partition, Mapper >::manager	(	Partition const &	partition,
		Mapper const &	mapper
	)

Create a manager with a given partition and mapper.

Parameters

p	The partition of the container
m	The mapper of the container

manager() [2/2]

template<typename Partition, typename Mapper>

template<typename PartitionContainer >

stapl::directory_impl::manager< Partition, Mapper >::manager	(	PartitionContainer const *const	part_cont,
		Partition const &	partition,
		Mapper const &	mapper
	)

Create a manager for an arbitrary distribution specified by the elements of part_cont and represented by the partition and mapper parameters.

Parameters

p	The partition of the container
m	The mapper of the container

Member Function Documentation

operator()()

template<typename Partition, typename Mapper>

std::pair<value_type, loc_qual> stapl::directory_impl::manager< Partition, Mapper >::operator()

(

gid_type const &

x

)

const

Look up the home location (manager location) of a GID.

Parameters

x	GID to lookup

Returns

The location responsible for x's metadata.

Note

The mapper is defined as mapping pContainer component ids to locations for data distribution. This manager is implementing a perfect mapping of home locations to storage locations as a result, unless element migration has changed the original distribution.
