real time vs sim time in finals #252

I don't understand the answer to #246 at all. In that issue, we have up to 300 hours of AWS time for the finals.

I thought we have only 24 hours of real time. In that case, using 2 machines with a sim time to real time factor of 0.16, then the most sim time we could possibly use is 24 2 .16 = 7.7 hours of sim time. And that is if you have 2 machines running for the entire 24 hours. Are you saying we can use 300 hours of sim time? Even with two machines that would be 150 hours / .16 = 937 hours of real time (about 40 days.......)

I must be misreading something.......been awake for a long time.

Oh wait, are you saying this is AWS real time hours? In that case, keeping the window open over 4 days with 2 machines would take 192 hours of AWS time. Is that what you are talking about?

The 24 hours was the number of AWS hours allocated to each team. You now have 300 hours of AWS time.

Thanks, just figured it out. Time for some sleep.
