Detailed Description

template<typename Storage, typename Boundary = OpenBoundary, std::size_t Halo = 1>
class Aleph::CA::Ghost_Lattice< Storage, Boundary, Halo >

Lattice with Halo ghost layers around the user-visible cells.

Template Parameters

Storage	storage type satisfying `CA::LatticeLike`. The storage is constructed with extents `user + 2*Halo` so that the halo is plain backing memory.
Boundary	boundary tag (default `OpenBoundary`). See the file-level documentation for the accepted tags.
Halo	halo thickness in cells (default 1). The neighbourhood radius consumed by the engine must be `<= Halo` for the fast path to kick in.

Complexity

at, set, at_safe: O(rank) (a few additions per call).
refresh_halo: O(boundary-surface cells), i.e. linear in the halo volume (which for 2D/3D is O(n^{rank-1})).

Thread-safety: Same guarantees as the underlying Storage.

◆ Ghost_Lattice() [1/2]

template<typename Storage , typename Boundary = OpenBoundary, std::size_t Halo = 1>

Aleph::CA::Ghost_Lattice< Storage, Boundary, Halo >::Ghost_Lattice ( )

default

Construct an empty ghost lattice (no cells allocated).

◆ Ghost_Lattice() [2/2]

template<typename Storage , typename Boundary = OpenBoundary, std::size_t Halo = 1>

Aleph::CA::Ghost_Lattice< Storage, Boundary, Halo >::Ghost_Lattice	(	const extents_type &	user_extents,
		const state_type &	init = `state_type{}`
	)

inlineexplicit

Construct a ghost lattice with given user extents and init value.

Allocates prod(user_ext + 2*Halo) cells and initialises every interior and halo cell with init. refresh_halo() is not called automatically, since the initial state of a CA is a pure user responsibility.

Parameters

[in]	user_extents	per-axis user-visible sizes.
[in]	init	initial value for every cell (default `state_type{}`).

Exceptions

std::bad_alloc on allocation failure.

◆ at()

template<typename Storage , typename Boundary = OpenBoundary, std::size_t Halo = 1>

state_type Aleph::CA::Ghost_Lattice< Storage, Boundary, Halo >::at ( const coord_type & c ) const

inline

Strict read through a user coordinate.

Parameters

[in] c user coordinate in [0, size(d)).

Exceptions

std::out_of_range if any component of c is out of range.

◆ at_safe()

template<typename Storage , typename Boundary = OpenBoundary, std::size_t Halo = 1>

state_type Aleph::CA::Ghost_Lattice< Storage, Boundary, Halo >::at_safe ( const coord_type & c ) const

inline

Boundary-aware read exploiting the halo as a fast path.

For a coordinate inside [-Halo, size(d) + Halo) on every axis this method performs a single direct read from the backing storage — no branch on the boundary policy, so interior steps are branch-free as long as the neighbourhood radius is <= Halo. For coordinates further out the slow path applies the policy on the fly so the function still honours the declared semantics.

Parameters

[in] c possibly out-of-range user coordinate.

Returns: the cell value resolved through the halo/policy pipeline.

Precondition: The halo is clean (i.e., refresh_halo() has been called after the last set() that modified an interior cell whose boundary reflection falls into the halo). If the halo is stale, reads of halo coordinates return the previously cached (potentially out-of-date) value.

◆ fill()

void Aleph::CA::Ghost_Lattice< Storage, Boundary, Halo >::fill ( const state_type & value )

inline

Set every user-visible cell to value.

The halo is left untouched; call refresh_halo() afterwards if you need it synchronised with the new interior.

template<typename Storage , typename Boundary = OpenBoundary, std::size_t Halo = 1>

template<typename F >

void Aleph::CA::Ghost_Lattice< Storage, Boundary, Halo >::for_each_halo_cell ( F && f ) const

inlineprivate

Invoke f(user_coord) on every halo cell of the storage.

user_coord uses the same convention as at(c): axes are in the user frame, so values in [-Halo, 0) or [user_ext[d], user_ext[d] + Halo) mean "halo cell on that side".

◆ refresh_halo()

template<typename Storage , typename Boundary = OpenBoundary, std::size_t Halo = 1>

void Aleph::CA::Ghost_Lattice< Storage, Boundary, Halo >::refresh_halo ( )

inline

Populate every ghost cell according to the boundary policy.

The engine calls this automatically before each step() so the rule loop can read neighbour values without any boundary branch. Calling it manually is harmless (idempotent under every policy implemented here).

Postcondition: All halo cells reflect the current interior state under the active boundary policy; at_safe() is now safe to call for any coordinate in [-Halo, size(d) + Halo).

Complexity: Linear in the number of halo cells (O(surface_area * Halo)).

template<typename Storage , typename Boundary = OpenBoundary, std::size_t Halo = 1>

state_type Aleph::CA::Ghost_Lattice< Storage, Boundary, Halo >::resolve_via_policy ( coord_type c ) const

Resolve a user coordinate through the boundary policy (slow path).

This is only used by at_safe when the coordinate steps outside the halo — i.e. when the neighbourhood radius exceeds Halo.

void Aleph::CA::Ghost_Lattice< Storage, Boundary, Halo >::set	(	const coord_type &	c,
		const state_type &	v
	)

inline

Strict write through a user coordinate.

Parameters

[in]	c	user coordinate in `[0, size(d))`.
[in]	v	value to write.

Exceptions

std::out_of_range if any component of c is out of range.

Precondition: c must be a valid user coordinate (each component in [0, size(d))).

Postcondition: The interior cell at c holds v. Halo cells that mirror interior cells (e.g. under ToroidalBoundary) are not updated automatically; call refresh_halo() before the next at_safe() call that may read the halo region.
