Public Member Functions
	TransformReduceArg (const std::vector< T * > &v, count_t n_items, transformer h, reduce_t init, reducer r)
Public Member Functions inherited from quda::ReduceArg< reduce_t >
	ReduceArg (int n_reduce=1)
void	complete (std::vector< host_t > &result, const qudaStream_t stream=0, bool reset=false)
	Finalize the reduction, returning the computed reduction into result. With heterogeneous atomics this means we poll the atomics until their value differs from the init_value. The alternate legacy path posts an event after the kernel and then polls on completion of the event. More...
void	complete (host_t &result, const qudaStream_t stream=0, bool reset=false)
	Overload providing a simple reference interface. More...
__device__ void	reduce2d (const reduce_t &in, const int idx=0)
	Generic reduction function that reduces block-distributed data "in" per thread to a single value. This is the legacy variant which require explicit host-device synchronization to signal the completion of the reduction to the host. More...
__device__ void	reduce (const reduce_t &in, const int idx=0)
