Description
Is it possible to set only "gpu" ? Is it possible to select default backend?

Another thing that I have concerns this – API device_context('opencl:gpu:0')
As user I don’t want to select backend or gpu device unless I would like to do so. And currently this are mandatory params. Even with DPC++ runtime i’m not providing such level of details – so I assume I shouldn’t do this in python as well.

Another point about specifying backend:
For now, we have to specify “OpenCL” backend if we run on CPU. But in oneDAL, we have no OpenCL dependency for CPU computations – we run native code. I think it’s incorrect to specify “OpenCL” backend in such cases where you don’t know what the actual backend will be used – why we need to specify it?
The same case for MKL – they run native GEN9-12 assembly on GPUs – I’m not sure we can specify “opencl” or “level0” backend here.
And what should the library do if the requested backend does not match the way how device support is implemented inside? Check backend type and throw an exception?

what’s about the host device on the dpctl side, which do not require to have any backend installed? I did not find this in your sources.
