Detailed Description

A backend that provides contexts for ViennaCL objects (vector, matrix, etc.).

Member Function Documentation

static viennacl::ocl::context& current_context ( ) [inline, static]

Returns the current active context.

static viennacl::ocl::command_queue& get_queue ( ) [inline, static]

Returns the current queue for the active device in the active context.

static void set_context_device_type	(	long	i,
		cl_device_type	t
	)			`[inline, static]`

Sets the context device type.

static void setup_context	(	long	i,
		cl_context	c,
		std::vector< cl_device_id > const &	devices,
		std::map< cl_device_id, std::vector< cl_command_queue > > const &	queues
	)			`[inline, static]`

Initializes ViennaCL with an already existing context.

Parameters:

	i	ID of the context to be set up
	c	The OpenCL handle of the existing context
	devices	A vector of OpenCL device-IDs that should be added to the context
	queues	A map of queues for each device

Sets a number of devices for the context.

Parameters:

	i	ID of the context to be set up
	devices	A vector of OpenCL device-IDs that should be added to the context

static void setup_context	(	long	i,
		cl_context	c,
		std::vector< cl_device_id > const &	devices,
		std::vector< cl_command_queue > const &	queue
	)			`[inline, static]`

Initializes ViennaCL with an already existing context.

Parameters:

	i	ID of the context to be set up
	c	The OpenCL handle of the existing context
	devices	A vector of OpenCL device-IDs that should be added to the context
	queue	One queue per device

static void switch_context ( long i ) [inline, static]

Switches the current context to the context identified by i.

Parameters:

i

ID of the new active context
