via your rosetta specific prefs.

Each task issued of the same wu type is the same with different seeds (starting points, I believe). Each wu can have 10's of thousands of models. The "run time" pref really means "run as many models as you can in X time". However, If it takes your processor 2 hours to do a model, but you have it set to only one hour, then it'll run two hours and finish. The longer the setting and the faster the machine, then the more closely it'll actually stop at your desired pref. If it takes 2hr/model, and you set it to 24 hours, then you'll complete 12 of those models (out of the 10's of thousands or however many there are for that type)

Using the menu's on the website under Participants > R@H Preferences! It's not done through BOINC manager on your machine.

Also, if it is set to 1 hour, and your first Model took 40 minutes, it will finish with that one model, because it knows it will not finish in 1 hour.

it doesn't, but it doesn't matter. Each wu type sent is the same, but with a different starting point. Each contains many, many models. The number of models done is defined by the speed of your processor and your run time.

So, for one wu type you might start at model 1111, but I might start at 4444. Let's say you do 5 models and I do 4, then models 1111-1116 and 4444-4448 are now done. I assume they overlay all the results later and see where they're are gaps in the complete picture, then reissue that wu type with starting points where they need coverage.
