Member Function Documentation

hpx::opencl::buffer hpx::opencl::device::create_buffer	(	cl_mem_flags	flags,
		std::size_t	size
	)		const

Creates an OpenCL buffer.

Parameters:

flags	Sets properties of the buffer. Possible values are CL_MEM_READ_WRITE CL_MEM_WRITE_ONLY CL_MEM_READ_ONLY CL_MEM_HOST_WRITE_ONLY CL_MEM_HOST_READ_ONLY CL_MEM_HOST_NO_ACCESS and combinations of them. For further information, read the official OpenCL Reference.
size	The size of the buffer, in bytes.

hpx::opencl::program hpx::opencl::device::create_program_with_binary ( const hpx::serialization::serialize_buffer< char > binary ) const

Creates an OpenCL program object from a prebuilt binary.

One can create a prebuilt binary from a compiled hpx::opencl::program with program::get_binary()

Parameters:

binary The binary execution code for the program.

hpx::opencl::program hpx::opencl::device::create_program_with_source ( const hpx::serialization::serialize_buffer< char > source ) const

Creates an OpenCL program object.

After creating a program object, one usually compiles the program an creates kernels from it.

One program can contain code for multiple kernels.

Parameters:

source The source code string for the program.

template<cl_device_info Name>

hpx::future<typename detail::device_info<Name>::type> hpx::opencl::device::get_device_info ( ) const [inline]

Queries device infos.

The template argument defines the type of information. A complete list can be found on the official OpenCL Reference.

template<cl_platform_info Name>

hpx::future<typename detail::platform_info<Name>::type> hpx::opencl::device::get_platform_info ( ) const [inline]

Queries platform infos.

The template argument defines the type of information. A complete list can be found on the official OpenCL Reference.
