Function Documentation

reduction()

__kernel void reduction	(	__global T *	input,
		__global T *	output,
		unsigned int	N,
		__local T *	lmem
	)

Reduction step. The objective of each step is obtain only one reduced value from each work group. You can call this kernel recursively until only one work group will be computed, and therefore just one output value will result.

Parameters

input	Input array to be reduced.
output	Output array to store the reduced value.
N	Number of input elements.
lmem	local memory address array to store the output data while working.
