get_compute_device_infoget_compute_device_infoGetComputeDeviceInfoGetComputeDeviceInfoget_compute_device_info (Operator)
Name
get_compute_device_infoget_compute_device_infoGetComputeDeviceInfoGetComputeDeviceInfoget_compute_device_info — Get information on a compute device.
Signature
Description
The operator get_compute_device_infoget_compute_device_infoGetComputeDeviceInfoGetComputeDeviceInfoGetComputeDeviceInfoget_compute_device_info returns information on a
compute device. In contrast to get_compute_device_paramget_compute_device_paramGetComputeDeviceParamGetComputeDeviceParamGetComputeDeviceParamget_compute_device_param, only
static information is queried, so that the device does not have to
be opened (see open_compute_deviceopen_compute_deviceOpenComputeDeviceOpenComputeDeviceOpenComputeDeviceopen_compute_device) and activated
(see activate_compute_deviceactivate_compute_deviceActivateComputeDeviceActivateComputeDeviceActivateComputeDeviceactivate_compute_device).
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 platform. 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""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.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.

Returned information.
Result
The operator get_compute_device_infoget_compute_device_infoGetComputeDeviceInfoGetComputeDeviceInfoGetComputeDeviceInfoget_compute_device_info returns the
value TRUE if the parameters are correct. Otherwise
an exception will be raised.
