Jon, the idea is to be able to have this information as seen from the Libomptarget and runtime itself. It doesn’t really intend to replace the stand alone tool for each vendor. Developers using openMP could isolate the runtime and its view of the system without having to write code and compile it. I’m thinking of adding the value that goes on the -fopenmp-targets flag so the user knows what devices are supported and how to compile for them. And what are their characteristics.

Think of remote offloading, virtual GPU and other targets that may not have access to an nvidia-smi like tool.  I believe this is also why PGI provides it as well.
