Detailed Description

template<class Limiter, class Model>
struct pops::detail::AssembleRhsHllCachedKernel< Limiter, Model >

AssembleRhsHllCachedKernel: kernel of the residual R = -div Fhat + S for the HLL flux with wave speeds PRE-COMPUTED per cell (scratch ws, 4 components).

Reconstruction and numerical flux IDENTICAL to AssembleRhsKernel<.., HLLFlux>; only the source of the signal speeds changes: instead of hll_speeds (per-face recall of model.wave_speeds), each face bounds sL/sR by min/max of the cached speeds of its two adjacent cells – exactly the Davis estimates of the per-face path when the reconstructed states equal the cell values (NoSlope). Named functor (device-clean cross-TU). POPS_HD.
