This sample demonstrates how to execute an query OpenVINO™ Runtime devices, prints their metrics and default configuration values, using :doc:`Properties API <openvino_docs_OV_UG_query_api>`.
|
|
|
|
The following C++ API is used in the application:

|
| Available Devices | ``ov::Core::get_available_devices``, | Get available devices information and configuration for inference |
|
|
| | ``ov::Core::get_property`` | |
|
