Fairseq: What is wall and train_wall in the output log?

[asispatra]

In the scalling_nmt example training output log there is two column named "wall" and "train_wall".
What does these two column means? How this is related to training time?

[myleott]

"wall" is the total time, including time spent in validation, saving checkpoints to disk, etc. In the paper we reported "train_wall," which is just the time spent in training.
