The tutorial explicitly addresses this. See

To know that a simulation ran on the GPU, you must inspect the log file
that it wrote.

If the display is sharing the GPU, then it shares the GPU (and performance
of either the display or the simulation might be affected). With only one
GPU, there's no option (unless your motherboard has a built-in GPU that
you'd prefer to use for the display).

No, there's nothing unusual about that, so the generic instructions apply.
