Detailed Description

template<typename GID, typename Index = GID, typename ContainerGID = GID, typename CID = unsigned long int>
struct stapl::block_map< GID, Index, ContainerGID, CID >

Computes a block mapping of ids to partitions.

The struct is used to implement view-based specifications of block and block-cyclic distributions. The implementation assumes division of a GID instance by a Index instance produces a value that is convertible to the Index type.

Member Function Documentation

update()

template<typename GID , typename Index = GID, typename ContainerGID = GID, typename CID = unsigned long int>

void stapl::block_map< GID, Index, ContainerGID, CID >::update	(	std::vector< std::tuple< std::pair< GID, GID >, CID, location_type >> const &	updates,
		size_t	level
	)

Method required of all mapping functions. The method is called by the update_distribution method of containers.

Warning

Currently mapping functions used in view-based specifications other than arbitrary do not support updates.
