@Philadelphia ... as I've mentioned several times now, Moo doesn't always report the correct crunching time on multicard systems. If you OPEN the wu std_err it will show the start time and the stop time. The difference between the 2 is the wall time which is probably about 1/2 of what is being reported. As you discovered watching the time to crunch a wu it isn't the same as what is being shown on the project CPU/GPU time.
