Detailed Description

template<class Model>
struct pops::detail::WaveSpeedMatchKernel< Model >

Locates the cell DOMINATING the CFL (dt_hotspot diagnostic, ADC-182): EQUALITY scan of the recomputed w – same functor and same data as MaxWaveSpeedKernel, hence bit-equal to the max returned by max_wave_speed_mf – which encodes the GLOBAL index j*nx + i as Real (exact as long as nx*ny < 2^53) and reduces to the MIN (first cell in lexicographic order: deterministic).

NAMED functor (cross-TU instantiation under nvcc).
