Description

open_compute_deviceOpenComputeDevice opens the compute device referenced by DeviceIdentifierdeviceIdentifierdevice_identifier and returns DeviceHandledeviceHandledevice_handle. Enable computation on DeviceHandledeviceHandledevice_handle via activate_compute_deviceActivateComputeDevice.

DeviceIdentifierdeviceIdentifierdevice_identifier must be obtained by query_available_compute_devicesQueryAvailableComputeDevices.

Execution information

Execution information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).

• Multithreading scope: local (may only be called from the same thread in which the window, model, or tool instance was created).

• Processed without parallelization.

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.

Parameters

DeviceIdentifierdeviceIdentifierdevice_identifier (input_control) integer → (integer)HTuple (Hlong)HTuple (int / long)intHtuple (Hlong)

Compute device Identifier.

DeviceHandledeviceHandledevice_handle (output_control) compute_device → (handle)HTuple (HHandle)HComputeDevice, HTuple (IntPtr)HHandleHtuple (handle)

Compute device handle.

Result

open_compute_deviceOpenComputeDevice returns the value 2 (H_MSG_TRUE) if DeviceIdentifierdeviceIdentifierdevice_identifier is valid. Otherwise an exception will be raised.
