Description

The operator get_compute_device_infoget_compute_device_infoget_compute_device_infoGetComputeDeviceInfoGetComputeDeviceInfo returns information on a compute device. In contrast to get_compute_device_paramget_compute_device_paramget_compute_device_paramGetComputeDeviceParamGetComputeDeviceParam, only static information is queried, so that the device does not have to be opened (see open_compute_deviceopen_compute_deviceopen_compute_deviceOpenComputeDeviceOpenComputeDevice) and activated (see activate_compute_deviceactivate_compute_deviceactivate_compute_deviceActivateComputeDeviceActivateComputeDevice).

The following information can be queried:

'vendor'

Vendor of the compute device.

'name'

Name of the compute device.

'platform_version'

Version of the compute device platorm. E.g. OpenCL version in the case of OpenCL devices.

'driver_version'

Version of the device driver.

'extensions'

Supported OpenCL extensions.

'image_support'

'true'"true""true""true""true" if the device supports image objects.

'image2d_max_width'

Maximum width of OpenCL image objects.

'image2d_max_height'

Maximum height of OpenCL image objects.

Returned information.

Result

The operator get_compute_device_infoget_compute_device_infoget_compute_device_infoGetComputeDeviceInfoGetComputeDeviceInfo returns the value 2 (H_MSG_TRUE) if the parameters are correct. Otherwise an exception will be raised.
