About Train Devices and Time

[zhangguanghui1]

How many graphics cards do you use for training and how long is the training time?
Thank you!

Same question. I'm using a server with 4 TITAN XP GPUs. When I ran the code, only 1 GPU was used. It took around 7s to run for one step. For 100 epochs and 915 steps/epoch, it will probably take quite a long time (7100915s, i.e., ~177 hours) to train the model. This training time is really unacceptable. Maybe I'm missing something configurations.
