Name

open_compute_deviceopen_compute_deviceopen_compute_deviceOpenComputeDeviceOpenComputeDevice — Open a compute device.

Signature

Description

open_compute_deviceopen_compute_deviceopen_compute_deviceOpenComputeDeviceOpenComputeDevice opens the compute device referenced by DeviceIdentifierDeviceIdentifierDeviceIdentifierDeviceIdentifierdeviceIdentifier and returns DeviceHandleDeviceHandleDeviceHandleDeviceHandledeviceHandle. Enable computation on DeviceHandleDeviceHandleDeviceHandleDeviceHandledeviceHandle via activate_compute_deviceactivate_compute_deviceactivate_compute_deviceActivateComputeDeviceActivateComputeDevice.

DeviceHandleDeviceHandleDeviceHandleDeviceHandledeviceHandle must be obtained by query_available_compute_devicesquery_available_compute_devicesquery_available_compute_devicesQueryAvailableComputeDevicesQueryAvailableComputeDevices.

Parallelization

• 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.

Parameters

Result

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