OpenCLDeviceImageSupport	Image support.

Definition at line 42 of file cl_query.hpp.

Function Documentation

std::size_t vsmc::cl_min_global_size	(	std::size_t	N,
		std::size_t	local_size
	)

inline

The minimum global size that is a multiple of the local size.

Definition at line 69 of file cl_manip.hpp.

void vsmc::cl_minmax_local_size	(	const ::cl::Kernel &	kern,
		const ::cl::Device &	dev,
		std::size_t &	factor,
		std::size_t &	lmax,
		std::size_t &	mmax
	)

inline

Query the preferred factor of local size.

Parameters

kern	An OpenCL kernel
dev	An OpenCL device
factor	Multiplier factor of local size for optimzied performance
lmax	Maximum of the local size
mmax	Maximum of the multiplier of the factor

Definition at line 48 of file cl_manip.hpp.

std::size_t vsmc::cl_preferred_work_size	(	std::size_t	N,
		const ::cl::Kernel &	kern,
		const ::cl::Device &	dev,
		std::size_t &	global_size,
		std::size_t &	local_size
	)

inline

The preferred global and local size.

Returns: The difference between the preferred global size and the N

Definition at line 82 of file cl_manip.hpp.

template<typename Arg1 , typename... Args>

void vsmc::cl_set_kernel_args	(	::cl::Kernel &	kern,
		::cl_uint	offset,
		const Arg1 &	arg1,
		const Args &...	args
	)

inline

Set OpenCL kernel arguments.

The first argument arg1 is set with index offset and the next with index offset + 1 and so on. For C++11 implementations that support variadic template, there can be arbitrary number of arguments (or limited by the compiler's implementation). Otherwise this function supports up to 16 arguments.
