Detailed Description

Instance layouts are templated on the type of the IndexSpace used to index them, but they all inherit from a generic version.

choose_instance_layout() [1/2]

template<int N, typename T >

static InstanceLayoutGeneric * Realm::InstanceLayoutGeneric::choose_instance_layout ( IndexSpace< N, T >  is, const InstanceLayoutConstraints &  ilc, const int  dim_order[N]  )

static

Create an affine layout using the bounds of 'is' (i.e. one piece) using the requested dimension ordering and respecting the field size/alignment constraints provided.

Parameters

is	Index space to use for layout creation.
ilc	Layout constraints to use for layout creation.
dim_order	Dimension ordering to use for layout creation.

Returns

InstanceLayoutGeneric* Pointer to the created layout.

choose_instance_layout() [2/2]

template<int N, typename T >

static InstanceLayoutGeneric * Realm::InstanceLayoutGeneric::choose_instance_layout ( IndexSpace< N, T >  is, const std::vector< Rect< N, T > > &  covering, const InstanceLayoutConstraints &  ilc, const int  dim_order[N]  )

static

Create a multi-affine layout using one piece for each rectangle in 'covering' using the requested dimension ordering and respecting the field size/alignment constraints provided.

Parameters

is	Index space to use for layout creation.
covering	Rectangles to use for layout creation.
ilc	Layout constraints to use for layout creation.
dim_order	Dimension ordering to use for layout creation.

Returns

InstanceLayoutGeneric* Pointer to the created layout.
