about time in Table 4. The KITTI 2015 leaderboard presented?

[Peterisfar]

in the Table 4, PSMNet's time is 0.41......so, i want to know the your environment (use gpu or cpu?),and this time is got in the "Test_img.py" or in the "submission.py"(in a word, time is got by single test image or average times of all test images?)

[JiaRenChang]

The runtime is tested on an Nvidia Titan X pascal which averaged with KITTI test set.
