USM Selector

---

In this exercise you will learn how to find a suitable device for using the USM data management model.

---

1.) Create a device selector

Create a custom device selector as you did in the "Device Discovery" exercise.

2.) Check for USM support

Within this device selector check for whether the device being inspected has support for the USM device allocations.

This can be querying for the aspect::usm_device_allocations aspect.

3.) Create a queue

Once you have a device selector which will choose a device which supports USM create a queue using it to select its device, remember to handle errors.
