+How much GPU is being used? It doesn't seem very fast...
+--------------------------------------------------------
+
+If everything is setup correctly, the GPU should be used regularly as the gradient calculations are offloaded. If you run NVIDIA's monitoring tool it looks something like this:
+
+.. code:: bash
+    # gpu   pwr  temp    sm   mem   enc   dec  mclk  pclk
+    # Idx     W     C     %     %     %     %   MHz   MHz

+The third column is the utilitazition of compute resources, and the fourth column is the use of memory.  If memory is under-used you can increase resolution!  If compute is under allocated too you can try running multiple scripts in parallel!
+
+**FIX:** Run ``nvidia-smi dmon`` and check the ``sm`` column.
