Function Documentation

clm4rm_and()

__kernel void clm4rm_and	(	write_only_global	C,
		read_only_global	A,
		read_only_global	B
	)

OpenCL kernel for bitwise AND on three matrixes C := A & B.

Parameters

C	destination matrix
A	source matrix
B	source matrix

Definition at line 35 of file clm4rm_bitwise.cl.

clm4rm_copy()

__kernel void clm4rm_copy	(	__global unsigned int *	C,
		int	C_rowstride,
		__global unsigned int *	B,
		int	B_rowstride,
		int	offset
	)

copy with offset

Deprecated:

(only needed for concat/stack with __global buffers not needed for Image2D).

C += B >> x

Definition at line 84 of file clm4rm_bitwise.cl.

clm4rm_or()

__kernel void clm4rm_or	(	write_only_global	C,
		read_only_global	A,
		read_only_global	B
	)

OpenCL kernel for bitwise OR on three matrixes C := A | B.

Parameters

C	destination matrix
A	source matrix
B	source matrix

Definition at line 60 of file clm4rm_bitwise.cl.

clm4rm_query_diagonal()

__kernel void clm4rm_query_diagonal	(	read_only_global	M,
		int	M_nrows,
		volatile __global int *	result
	)

Query Matrix Diagonal.

Parameters

M	a square matrix
M_nrows	number of rows and columns in M
result	holds on return a row/column index with a 1 on the diagonal; -1 if the diagonal is empty
