I have had several WU i completed in Nov time frame which are still pending granted credit. I checked the other participant on one and they had over 1400 WU in progress. There average turn around was 55 days. | |

I agree with you, found 1 had a 1 gig computer and has 100 work units to process, turn around time is 8 days. | |

I agree with you, found 1 had a 1 gig computer and has 100 work units to process, turn around time is 8 days. Turn around time of 8 days doesn't mean that this computer produces 1 result per 8 days. BOINC is like conveyor - it gets WorkUnits from one side and gives results to the other. Turn around time of 8 days means that WU entered the queue 8 days before it has been processed (i.e. computed, produced result, result uploaded & reported) Meanwhile (while this WU has been waiting in the queue) the computer ended and reported many more WU/results (10...100) Your computer "AMD Athlon(tm) 64 X2 Dual Core Processor 3800+" has "Average turnaround time 2.82 days" but I'm sure that it computes a WU every 2-4 hours. **************************************** ---> Suggestion to Web pages developer: Add "Average number of results computed/uploaded/reported per day" because many people confuse that to be equivalent to "Average turnaround time" **************************************** | |

Turn around time depends on several factors, among them: | |

It has to be noted clearly that "Turn around time" has NO direct corelation with RAC. "Size of the cache" has impact on the "Turn around time" but NOT on the RAC "Number of projects attached and the resource shares allocated. The amount of time the computer spends on" HAVE impact on the RAC. You can have big ("slow") "Turn around time" AND have good RAC if your computer: - is fast (whatever that means) - works all the time (BOINC is allowed to run 100% of the time using 100% CPU) - is almost idle all of the time (not running "heavy" apps - i.e. you use it mainly for textprocessing, web browsing, play Solitaire :), etc... ) (some (3D "fancy") screen savers ARE in fact "heavy" apps - if you use them they "eat" CPU time and very often they continue to run after the monitor is asleep and you can't see them) - you don't "sleep" the computer, only the monitor ("sleeping" computer is of course not working (but the LEDs and (maybe) fans :) )) . | |

Yes, The number of projects attached and the amount of time that the computer spends on have a correlation with RAC. They also have a correlation with turn around time. Example: The user has a cache of 0.1 days, and takes 3 hours to complete a task. If the computer is only on for 2 hours a week, the computer is going to have a turn around time of about a week. If the only thing you change is the time spent on to 24 / 7, the computer is going to have a turn around time of around 5.4 hours (3 hours compute time + 0.1 hours waiting in the queue). I have several computers attached to over 50 projects. Most tasks are completed just prior to the computation deadline, and returned not long before the report deadline. This makes the turn around time just about the same as the initial time to deadline. ____________   BOINC WIKI | |
