名称

open_compute_deviceT_open_compute_deviceOpenComputeDeviceOpenComputeDeviceopen_compute_device — Open a compute device.

参数签名

open_compute_device( : : DeviceIdentifier : DeviceHandle)

描述

open_compute_deviceopen_compute_deviceOpenComputeDeviceOpenComputeDeviceOpenComputeDeviceopen_compute_device opens the compute device referenced by DeviceIdentifierDeviceIdentifierDeviceIdentifierDeviceIdentifierdeviceIdentifierdevice_identifier and returns DeviceHandleDeviceHandleDeviceHandleDeviceHandledeviceHandledevice_handle. Enable computation on DeviceHandleDeviceHandleDeviceHandleDeviceHandledeviceHandledevice_handle via activate_compute_deviceactivate_compute_deviceActivateComputeDeviceActivateComputeDeviceActivateComputeDeviceactivate_compute_device.

DeviceIdentifierDeviceIdentifierDeviceIdentifierDeviceIdentifierdeviceIdentifierdevice_identifier must be obtained by query_available_compute_devicesquery_available_compute_devicesQueryAvailableComputeDevicesQueryAvailableComputeDevicesQueryAvailableComputeDevicesquery_available_compute_devices.

运行信息

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.

参数表

DeviceIdentifierDeviceIdentifierDeviceIdentifierDeviceIdentifierdeviceIdentifierdevice_identifier (input_control) integer → (integer)

Compute device Identifier.

DeviceHandleDeviceHandleDeviceHandleDeviceHandledeviceHandledevice_handle (output_control) compute_device → (handle)

Compute device handle.

结果

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