Where are the "atomic" operations used in PyFR?

I notice in pyfr/banckend/hip/driver.py file in class “HIPDevProps” , some atomic functions are listed, like this , where are these operations used in PyFR ?

To the best of my knowledge they aren’t used. These are listed here as part of the HIPDevProps class, which is a python side definition of a HIP data struture used to hold device properties.
