Function Documentation

template<typename T >

int check	(	T *	x,
		T *	x_gold,
		int	n,
		char *	str
	)

Verify that host and device results are identical.

Parameters

x	(in) Vector of CUDA results
x_gold	(in) Vector of host results
n	(in) Number of elements to show
str	(in) Label indicating vector being tested

Definition at line 30 of file prefixScan.cu.

int main

(

void

)

Perform blockwise prefix scan.

Notes

• Each thread handles one element of vector.
