Does anyone know what this setting does ? thanks in advance |

It sets approximately how long a rosetta task will run for. After the time has expired the client will finish the current model/decoy then end and report the task. BOINC WIKI BOINCing since 2002/12/8 |

I've tried to find an answer, which the previous does not satisfy nor the FAQ.... we know we can set the WU to process according this "Target CPU run time" preference. Previously i had not set it, now i have put it to 4 hours CPU time, so it does more 'angles/models' on a single WU, for which proportionate more credit is granted. Now the more cycles are run on a single WU, the more chance of finding a very low energy one.....now the question..... How do the scientists determine which of the returned WU's crunched for say only default 3 hours identify themselves as having the potential to go much lower i.e. had it been run 4, 6, 8, 24 hours? If i got it all wrong, fine....disregard the question. Coelum Non Animum Mutant, Qui Trans Mare Currunt |

The way I understand it each workunit is composed of a varying number of models/decoys/trajectories each of which is basically a complete and discreate unit. It does not matter to the science if 10 workunits do 100 decoys or 100 workunits do 10 decoys, either way it is still 10,000 attempts to find the best configuration.

Don't know if these WU's are generated real time at sending, but if my prefs are set for 4 hours which can do X models in the given time frame at given CPU speed, then how does the system track for it not to duplicate models of the same WU send to someone else (if the target is to get a preset global total of models for each WU)?

Random seeds are set by the the servers. though we are going way beyond the intial question. It is really just a bandwidth saver if you run it longer than the default, well probably 8hrs to 24hrs. Though that is not a suitable length for people that don't have their computers on for very long where a shorted run time is beneficial, they get the results sent back before it goes over the deadline.

The runtime preference doesn't make your models better. It just makes more of them. So the science about how to produce a good model from a given random point is the same either way. Rosetta Moderator: Mod.Sense |

Hi, I hope it's OK to re-open this old thread. I'm fairly new to Rosetta, I'm running it a lot more at the moment while SETI is out of work. I currently have my run time set to to the max 24 hours, is this optimal? I have an AMD Athlon XP 2200+ with 256MB RAM, running Windows XP Pro SP2. I also have a Pentium II 233MHz with 512MB RAM running Windows 98SE which I know is below the minimum reccomended spec, but it does manage to do some work sucessfully. I would not mind this machine running each task for >24 hours if it is possible. So in summary, what is the optimal run time per task, and is there a way to go beyond 24 hours? |

Hi Keith T For the moment 24H is max on run time. The servers get less trafic the longer runtine we users select so in that way your in top of the class :) Your PII should do just fine with a long runtime, slow computers have trouble staying within runtime pref. if you have 1 or 2 H setting.
