Where's the logic in continually running into/past the deadline of WUs? Where's the logic in deleting WUs that are getting too close to the deadline that have not been BOINCed yet? What I'm saying is that there's no reason to participate in a project if less than 100% of the WUs don't get BOINCed and reported before the deadline. In regards to my first post, people here assumed I was saying that I thought people participating here should run their PC[s] 24/7. I did not say that. I stated what I do: I run mine 24/7/365. There are others, many others here that do the same. L8R.... T'Khasi Time: Thursday, 14 April 2005 - 06:07 AM --700 (Pacific Standard Time) CAPT Siran d'Vel'nahr - L L & P _\\// Winders 11 OS?

i crunch 24/7/365 also (provided my cable modem doesn't freak out again). if i get 2 WU's or 6, i make sure that i do everything in my power to crunch and report these WU's so that not only will i get the credit i deserve, but that someone else will get (on-time). what good does it do to upload it and then turn the computer off? who does it help? i have a WU right now that i KNOW originally had a "due date" of 4/14/05, now for some reason it's due (for someone else) later than that it's been pending for quite a while now, not only does the change in due date confuse me, but the amount of credit granted for someone who doesn't even complete it, or manages (sometimes through no fault of their own) to have errors in it and i'm left with alot of wasted crunch time on a WU that probably wasn't worth the time (then again it could be "the one") (wondering if the next upgrade will contain a button to poke the guy who is not sending in his results on time...)

Hi; If you Reset the BOINC Project, it will throw out ALL the downloaded work units on your machine, and download new ones...

> i crunch 24/7/365 also (provided my cable modem doesn't freak out again). Kaj, do you have Comcast? They are typically very reliable, but I have been having some serious issues with my connection the past few evenings (that I know aren't on my end). It's always up by morning, but is becoming very agravating. <br><br><img src='http://www.boincsynergy.com/images/stats/1185sah.png'> <br> Thanks to Tim (Captain Avatar) for my groovy Red Foxx avatar! |

what has bothered me the most about cablelynx is that on the few occasions where i do actually have a night off from work i stay up until about 1:30 in the morning on here, i go to bed... what i don't know until i wake up is that ten minutes after i went to bed the connection was lost and some results didn't go in until i hit "update"...i don't want to micromanage anything i have running on boinc, but i am beggining to have to do that for my connection. thinking maybe i need a babysitter...

It would be good to provide some info about what unit you are referring to. Possibly credit has been granted and is has now been deleted. Due dates do not change. The due date is two weeks from the time it is sent out to a computer. If someone gets it later it will be due later. > > it's been pending for quite a while now, not only does the change in due date > confuse me, but the amount of credit granted for someone who doesn't even > complete it, or manages (sometimes through no fault of their own) to have > errors in it and i'm left with alot of wasted crunch time on a WU that > probably wasn't worth the time (then again it could be "the one") > I have never seen someone get credit who has not completed a workunit. Once again, it would be good to provide a link to the result in question. I don't see any unit in your list of results that looks like the one you are referring to. > (wondering if the next upgrade will contain a button to poke the guy who is > not sending in his results on time...) > It would be good if somehow people could be notified if a computer is having problems. I have been watching a few that are completing up to 190 units a day and claiming very low completion times and credits. They are getting no credit due to the results being invalid. Either they are just going for completing a high number of results (which is pointless) or they don't realize what is happening. |

The feature to assign extra time to WU will also be a welcome addition. |

Just to add to the discussion, what's the logic in mistuning your parameters? I think the biggest single problem is not how BOINC works, but a lack of understanding how parameters like "connect every 'x' days" behave. There should probably be some logic to "starve" a new host slightly during the first few days -- until BOINC has had time to estimate the on-time. Maybe limit to two days until a week's worth of work has come in? Without that, someone can get 10 days of work based on 24 hours/day, and if they only run 8 hours then most of the initial batch will go past the deadline (by then BOINC will know how much to feed and everything is fine). |

> I think the biggest single problem is not how BOINC works, but a lack of > understanding how parameters like "connect every 'x' days" behave. > Very true. I'm new to BOINC so i've been pretty conservative with my settings. I have my "connect every" parameter set to 1 day right now, and after three weeks of normal operation i see that my average turn around time is .98 days. I'll probably up my cache to 2 days now and watch it for a while, then go from there. I realize not everyone has a whole lot of time to spend on this, but it appears that some folks just go for the max cache, walk away from it, and ignore any possible ramifications. It almost seems kind of rude in a way... grab as many as you can and everyone else be damned. Oh well. :) Dig |

there were 5 wu's pending, i see only 3 now WU 12462325 took me nearly twice as long as everyone else to complete, but got very little for it. WU 12385597 will probably earn no credits... I honestly don't really care about the credit, i'm not here for the credit, maybe i'm overwatching (is that a word?) my stats too much. i can't find the work unit i was talking about earlier (with the changed date on it), it was there this morning when i got off work, oh well... sorry about the complaining, it's been a rough week No matter where you go, there you are... |

Except for the various "outages" that SETI/BOINC has had, I have not come even close to any deadline. During the "outages" I came close but didn't overrun any. L8R....
