I have tried to run the code on a server with 4 Nvidia GPUS and the performance drops 6 times with respect to using a CPU on a notebook.
Is there a way to exploit GPUs better?

hi attardi,
I have been working on some urgent projects recently and hopely will investigate the problem a.s.a.p.
For a short try, could you please test replacing the l2 regularization (lines 339 to 350) with tf.nn.l2_loss() ? In our experience, it help boosting the program.
