Dear QE users,

I ran a structure relaxation with version 6.3 of pw.x
In the output file I read:

....
>     Parallel routines
>      fft_scatt_xy :    101.43s CPU    107.82s WALL ( 1391222 calls)

The job actually took 1h 04m to run, while the final display value looks
different. Moreover, I don't understand the "4h" line before the end of the
file.
Am I missing something in the displayed elapsed time in version 6.3?
Thank you very much for your attention!
Best,

Michele
