Hello Query Device C++ Sample

This sample demonstrates how to execute an query OpenVINO™ Runtime devices, prints their metrics and default configuration values, using Properties API.

The following C++ API is used in the application:

Feature

API

Description

Available Devices

ov::Core::get_available_devices , ov::Core::get_property

Get available devices information and configuration for inference

Basic OpenVINO™ Runtime API is covered by Hello Classification C++ sample.

Options

Supported devices

All

Other language realization

Python

How It Works

The sample queries all available OpenVINO™ Runtime devices, prints their supported metrics and plugin configuration parameters.

Building

To build the sample, please use instructions available at Build the Sample Applications section in OpenVINO™ Toolkit Samples guide.

Running

To see quired information, run the following:

hello_query_device

Sample Output

The application prints all available devices with their supported metrics and default values for configuration parameters:
