Switching the example from buffers to USM, because:

USM is closer to how CUDA/HIP work, so added educational value,
more relevant for the HPC community, since buffers are, in practice, slower (even on this example),
should not suffer from the segfault seen on LUMI (presumably, something in ACpp runtime),
should have predictable performance regardless of how many CPUs/GPUs are available.

The only downside is that the code is a bit more verbose.
