accelerator_view Class

Represents a virtual device abstraction on a C++ AMP data-parallel accelerator.

class accelerator_view;

Members

Public Constructors

Name	Description
accelerator_view::accelerator_view Constructor	Initializes a new instance of the accelerator_view class.
accelerator_view::~accelerator_view Destructor	Destroys the accelerator_view object.

Public Methods

Name	Description
accelerator_view::create_marker Method	Returns a future to track the completion of all commands submitted so far to this accelerator_view object.
accelerator_view::flush Method	Submits all pending commands queued to the accelerator_view object to the accelerator for execution.
accelerator_view::get_accelerator Method	Returns the accelerator object for the accelerator_view object.
accelerator_view::get_is_debug Method	Returns a Boolean value that indicates whether the accelerator_view object has the DEBUG layer enabled for extensive error reporting.
accelerator_view::get_queuing_mode Method	Returns the queuing mode for the accelerator_view object.
accelerator_view::get_version Method	Returns the version of the accelerator_view.
accelerator_view::wait Method	Waits for all commands submitted to the accelerator_view object to finish.

Public Operators

Name	Description
accelerator_view::operator!= Operator	Compares this accelerator_view object with another and returns false if they are the same; otherwise, returns true.
accelerator_view::operator= Operator	Copies the contents of the specified accelerator_view object into this one.
accelerator_view::operator== Operator	Compares this accelerator_view object with another and returns true if they are the same; otherwise, returns false.

Public Data Members

Name	Description
accelerator_view::accelerator Data Member	Gets the accelerator object for the accelerator_view object.
accelerator_view::is_debug Data Member	Gets a Boolean value that indicates whether the accelerator_view object has the DEBUG layer enabled for extensive error reporting.
accelerator_view::queuing_mode Data Member	Gets the queuing mode for the accelerator_view object.
accelerator_view::version Data Member	Gets the version of the accelerator.

Inheritance Hierarchy

Remarks

An accelerator_view object represents a logical, isolated view of an accelerator. A single physical compute device can have many logical, isolated accelerator_view objects. Each accelerator has a default accelerator_view object. Additional accelerator_view objects can be created.

Physical devices can be shared among many client threads. Client threads can cooperatively use the same accelerator_view object of an accelerator, or each client can communicate with a compute device via an independent accelerator_view object for isolation from other client threads.

An accelerator_view object can have one of two queuing_mode Enumeration states. If the queuing mode is immediate, commands like copy and parallel_for_each are sent to the corresponding accelerator device as soon as they return to the caller. If the queuing mode is deferred, such commands are queued up on a command queue that corresponds to the accelerator_view object. Commands are not actually sent to the device until flush() is called.
