Solution
Introduction to USM
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 exercise 5.
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.
