描述
算子 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.
- 'max_mem_alloc_size'
Maximum size (in bytes) of an OpenCL memory block.
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
