alltoall_pd()

template<typename T , typename Tag >

skeletons_impl::alltoall_pd<T, Tag> stapl::skeletons::alltoall_pd

(

)

Creates the simplest alltoall parametric dependency skeleton.

pointer_jumping_pd()

template<typename Op >

skeletons_impl::pointer_jumping_pd<Op> stapl::skeletons::pointer_jumping_pd

(

Op const &

op

)

Creates a pointer-jumping parametric dependency given a op.

A pointer-jumping parametric dependency can be used in various skeletons. One good example is hillis_steele_scan in which scan is done in a non-work optimal but smaller tree.

stencil_2d_pd()

template<typename Op >

skeletons_impl::stencil_2d_pd<Op> stapl::skeletons::stencil_2d_pd

(

Op const &

op

)

Creates a 9-point stencil parametric dependency.

In a 2D stencil, parametric dependencies are defined in such a way that each node depends on every 9 node in its surroundings including itself from the previous timestep.
