Measure GPU occupancy when running the benchmark on a Flex 170 on Intel DevCloud

[ogrisel]

vtune can be installed from the oneAPI basekit.

Here is the command to record GPU statistics from the benchmark:

vtune -collect gpu-hotspots -- python kmeans.py --n-data-samples 5000000 --engine-providers sklearn-numba-dpex

and then generate a text summary from the commandline with something like:

vtune -report summary -r r000gh
