Classes
struct	DiFfRG::MapTarget
	Which resource a map() runs on and how many evaluations saturate one rank's share of it. More...
struct	DiFfRG::MapSlice
	This rank's window into the external grid of one QuadratureIntegrator::map() call. More...
class	DiFfRG::NoMapsHere
	Decides, without any user input, which rank computes which part of each map(). More...

Namespaces

Enumerations
enum class	DiFfRG::MapResource : int { DiFfRG::device = 0 , DiFfRG::host = 1 }
	The physical resource a map() competes for. More...

Functions
double	DiFfRG::internal::device_fill_threshold ()
	Kernel evaluations needed to saturate one rank's compute resource.
double	DiFfRG::internal::host_fill_threshold ()
const char *	DiFfRG::to_string (const MapResource r)
template<typename ExecutionSpace >
MapTarget	DiFfRG::map_target ()
	The scheduling target of an execution space, selected at compile time.
template<typename ExecutionSpace >
double	DiFfRG::map_fill_threshold ()
	The fill threshold alone, for callers that do not need the resource class.

Variables
constexpr double	DiFfRG::internal::host_grain = 1024.
constexpr double	DiFfRG::internal::launch_threshold = 1024.
	Evaluations below which a slice cannot pay for the launch that computes it.
constexpr int	DiFfRG::n_map_resources = 2
