Detailed Description

template<class P>
struct flecsi::topo::core< P >

An example core topology that is not really implemented.

Template Parameters

P	topology specialization, used here as a policy

Constructor & Destructor Documentation

core()

template<class P >

core ( coloring )

explicit

A topology can be constructed from its coloring type.

Member Function Documentation

colors()

template<class P >

Color colors

(

)

const

Return the number of colors over which the topology is partitioned.

get_region()

template<class P >

template<typename P::index_space >

data::region & get_region

(

)

Find the region for an index space.

get_partition()

template<class P >

template<typename P::index_space >

data::partition & get_partition

(

)

Find the partition for an index space.

Returns

a repartition if appropriate

Note

As a special case, the global topology does not define this.

ghost_copy()

template<class P >

template<class T , data::layout L, typename P::index_space S>

const data::copy_plan * ghost_copy ( data::field_reference< T, L, P, S > const & f )

nodiscard

Prepare a ghost copy.

Required only if multiple privileges are used.

Template Parameters

T	data type
L	use to trigger special copies for dynamic fields
S	use to identify relevant copy plan

Parameters

f	to deduce the above as well as for the field ID

Returns

the copy plan to use, if any
