teno_setup Namespace Reference

Classes
struct	Lane
	Element k of one cell's array in a batch: interleaved across cells on GPUs. More...
struct	Options
	Options and sizes of the 3D setup. More...
class	Setup3D
	The setup of one mesh. More...
class	Setup3DHandle
	The 3D TENO-E precomputation of a mesh: the geometry it needs (cell moments, bounding boxes and ranking metrics), computed once, and the tables of any batch of cells. Every cell's tables are a function of the mesh alone, computed with the same sequence of floating-point operations on the device and on the host, so they do not depend on the batch, the thread count or where they ran. More...
struct	SlotArray
	An array of cap elements for each of slots cells. On GPUs element k of every cell is contiguous, so that a warp working on consecutive cells reads consecutive words; on the host each cell's array is. More...
struct	TableBatchT
	Tables of a batch of cells before packing, one slot per cell, at the largest stencil sizes the searches allow. More...
struct	Timings
	Timings of the last setup, in seconds. More...

Typedefs

Enumerations
enum	Status : uint8_t { OK = 0 , OUT_OF_SCRATCH = 1 }
	Why a cell's device setup must be redone on the host. More...

Functions
bool	batch_interleaved ()
	Whether batches interleave their cells (GPUs).
TableBatch	device_copy (const TableBatchT< Kokkos::HostSpace > &h)
	The device copy of a host batch.
teno::SmoothnessTerms	smoothness_terms (uint8_t degree)
	The terms of every smoothness-matrix entry of the given degree, in the order the setup sums them.
uint16_t	n_moments (uint8_t degree)
	Central moments per cell for the given degree.
std::array< double, 9 >	ranking_metric (const Mesh &mesh, const Kokkos::View< int32_t * >::host_mirror_type &face_bc, const Kokkos::View< BoundaryCondition * >::host_mirror_type &bcs, uint32_t i)
	Metric (3 x 3, row-major) in which the stencil candidates of cell i are ranked by distance: the identity unless the spacing of its vertex neighbors (completed across its boundary faces by mirror images) is markedly anisotropic.
bool	one_sided_face (const Mesh &mesh, const BoundaryCondition &bc, const uint32_t f, const bool curved_mirrors)
	Whether stencils take no mirror images across boundary face f (with condition bc): curved wall and symmetry faces, which no reflection across a plane matches beyond second order, unless curved_mirrors. Curved far fields and inflows keep theirs.

Function Documentation

batch_interleaved()

bool teno_setup::batch_interleaved

(

)

Whether batches interleave their cells (GPUs).

device_copy()

TableBatch teno_setup::device_copy

(

const TableBatchT< Kokkos::HostSpace > &

h

)

The device copy of a host batch.

The device copy of a batch on the host.

n_moments()

uint16_t teno_setup::n_moments

(

const uint8_t

degree

)

Central moments per cell for the given degree.

one_sided_face()

bool teno_setup::one_sided_face ( const Mesh &  mesh, const BoundaryCondition &  bc, const uint32_t  f, const bool  curved_mirrors  )

inline

Whether stencils take no mirror images across boundary face f (with condition bc): curved wall and symmetry faces, which no reflection across a plane matches beyond second order, unless curved_mirrors. Curved far fields and inflows keep theirs.

ranking_metric()

std::array< double, 9 > teno_setup::ranking_metric	(	const Mesh &	mesh,
		const Kokkos::View< int32_t * >::host_mirror_type &	face_bc,
		const Kokkos::View< BoundaryCondition * >::host_mirror_type &	bcs,
		const uint32_t	i
	)

Metric (3 x 3, row-major) in which the stencil candidates of cell i are ranked by distance: the identity unless the spacing of its vertex neighbors (completed across its boundary faces by mirror images) is markedly anisotropic.

smoothness_terms()

teno::SmoothnessTerms teno_setup::smoothness_terms

(

const uint8_t

degree

)

The terms of every smoothness-matrix entry of the given degree, in the order the setup sums them.
