| The function used to map a partition id (CID) to a location. | |
Mapper which takes the functor mapping partition ids to locations from the distribution_view provided to the pContainer constructor.
The functor is user-defined, and as such no assumptions other than it implementing a many-to-one mapping can be made.
This struct is used in tandem with view_based_partition to allow users to describe the data distribution of a pContainer using a pView.
| DistributionView | Type of the view describing a distribution. |
| stapl::view_based_mapper< DistributionView >::view_based_mapper | ( | std::shared_ptr< DistributionView > | dist_view | ) |
Construct the mapper instance for a distribution specified by a set of chained views.
| dist_view | View-based specification of the distribution that will be used to map partition ids to location ids by this class |
| stapl::view_based_mapper< DistributionView >::view_based_mapper | ( | std::shared_ptr< DistributionView > | dist_view, |
| PartitionInfoContainer * | |||
| ) |
Construct the mapper instance for an arbitrary distribution specified by a container of instances.
The pointer to the container holding the arbitrary partition information is ignored as it is not needed. It is passed to the constructor to allow the initialized_deferred call to be invoked with the flag to avoid attempting to initialize the mapping functions in dist_view because they're not deferred_map instances.
| dist_view | View-based specification of the distribution that will be used to map partition ids to location ids by this class |
| void stapl::view_based_mapper< DistributionView >::update | ( | Info const & | info | ) |
Update the domain of partition ids and the mapping function from partition id to location id with mapping information on elements to be inserted in the container.
| info | vector of tuples, each of which specifies a contiguous set of GIDs, the partition id they map to, and the location id to which the partition id maps. |
