Classes
struct	TENOFunctor< DEG, PRIM, TABLE >
	Per-cell TENO-E reconstruction of degree DEG to the quadrature points of all of the cell's faces. SmoothPass finishes the cells below the troubled threshold and queues the others with their central coefficients. The troubled passes then work on that queue only, so the register-heavy path does not slow the smooth cells, and split it finely, so that the few troubled cells along shocks still fill the device: sector-stencil coefficients per (cell, sector), stencil selection per (cell, face, characteristic variable), the projection back to conservative variables per (cell, face), and admissibility per cell. Each pass loops over its share of the queue, whose length never has to be read back to the host. More...
