Beschreibung

Der Operator get_compute_device_infoget_compute_device_infoGetComputeDeviceInfoGetComputeDeviceInfoGetComputeDeviceInfo liefert Informationen über ein Compute Device. Im Gegensatz zu get_compute_device_paramget_compute_device_paramGetComputeDeviceParamGetComputeDeviceParamGetComputeDeviceParam werden nur statische Informationen abgefragt, so dass das Device weder geöffnet (open_compute_deviceopen_compute_deviceOpenComputeDeviceOpenComputeDeviceOpenComputeDevice) noch aktiviert (activate_compute_deviceactivate_compute_deviceActivateComputeDeviceActivateComputeDeviceActivateComputeDevice) sein muss.

Folgende Informationen können abgefragt werden:

'vendor'

Hersteller des Compute Devices.

'name'

Name des Compute Devices.

'platform_version'

Version der Compute Device Platform. Für OpenCL Devices ist dies die OpenCL Version.

'driver_version'

Version des Treibers des Compute Devices.

'extensions'

Unterstützte OpenCL Extensions.

'image_support'

'true'"true""true""true""true" wenn das Device Bild Objekte unterstützt.

'image2d_max_width'

Maximale Breite von OpenCL Image Objekten.

'image2d_max_height'

Maximale Höhe von OpenCL Image Objekten.
