Post: Hi. Sorry to do this but I want to ask Thyme Lawn about a mod he checked in for Boinc re 500 server errors. Can\'t find an email for him. If he would contact me perhaps john_brown_gordon at ntlworld dot com that would be great. Again sorry to use the forums this way. I have suggested to boinc_dev that there be a pm system for those of us that help out on boinc projects and want to get in touch from time to time. Cheers Ian |

Post: Boinc uses port 80 to talk to the scheduler and ul/dl server(s). Port 80 is also the port used for web access. I guess as Boinc tries for port 80 your new firewall etc thinks its a web access. You will have to open it I think. |

Post: I have one criticism of BOINC in an architectural sense. That is that it does not appear to be able to have clients connect and get/return work from/to multiple hosts such that those hosts can be in different locations. I would strongly recommend this for future consideration. I see the additional complexity but I do think a distributed computing system should distribute more than just the client processing. <img src="http://www.boincsynergy.com/images/stats/comb-1091.jpg"> |

Post: I have to say I'm not too happy my model went down the tubes here. Sure I get credits but there is no model result as far as I can see and that's why I ran it for week after week. I was out of the country and could not follow the advice from Thyme Lawn. Given that 14 days trying to upload by BOINC is, evidently, not a sufficiently long enough period can this be changed to avoid it happening again? Is this project configurable or is it BOINC wide? Disappointed! <img src="http://www.boincsynergy.com/images/stats/comb-1091.jpg"> |

Post: Well my model has not transferred up after 4 days...my trickles seem somewhat random in going but seem to go in big chunks of 6 or 8. No seti units left, no LHC to crunch bar the odd one that completes very quickly and Einstein doesn't seem to be sending me anything right now. So only one new cpdn model and 2 in progress. I actually have idle CPUs; amazing! <img src="http://www.boincsynergy.com/images/stats/comb-1091.jpg"> |

My guess having worked with both real-time and simulation systems is that system time changes need to be trapped/detected by keeping an artifical time within the model and using that to avoid harware clock inadeqaucies. Hourly checks by the cc should be adequate as even the most fiendish watcher of time (hehe ME!) will only adjust hourly I would guess. I know from my old job where time to a thousandth of a second was important, for judical reasons, an hour is as far as you need to go unless you have some pretty cheap hardware. <img src="http://www.boincsynergy.com/images/stats/comb-1091.jpg"></img><br><img src="http://www.iantighe.com/setisig.jpg"></img><img border="0" src="http://boinc.mundayweb.com/one/teamStats.php?userID=1602&prj=1&trans=off"> |

Tolerant to big changes but not to small changes. I moved mine by 65 or so seconds as I recall. My systems update every hour with my ntp server and I dont get this behaviour normally or at least I have nor detected it. But still....it sounds a decent candidate for further investigation as it has happened for two of us over three projects. Try a smaller change....60 secs? EDIT: Did you move backwards then forwards? May be sensitive to which way you go first.

Post: Great beer.....ahem....Paul doesn't drink beer.....damn! Oh well I'll pretend. @Paul sent you the logs. Let's hope it is something tbh as its always nice to find a reason for a problem even if you cannot fix it necessarily. Should I have a scan of the boinc code to see if I can find out where it is happening? Worth while? Regards Ian EDIT: Just checked Win 2003 server....will do a clock update using normal MS client every 7 days.So these incidents may be occuring every 7 days on some systems and more frequently if say an ntp client is in use where even hourly updates are sometimes requested. This would certainly add to the randomness "look" as it does not always follow there is a time change. Hmmm. <img src="http://www.boincsynergy.com/images/stats/comb-1091.jpg"></img><br><img src="http://www.iantighe.com/setisig.jpg"></img><img border="0" src="http://boinc.mundayweb.com/one/teamStats.php?userID=1602&prj=1&trans=off"> |

Post: Hi. Two models I have on a P4 HT PC both exited with 0 status but no finished file. I got the usual warning that if it happems repeatedly etc etc. Interestingly...I think.....It was in the same minute that the system clock was adjusted. I know this becuase it had slowed by over 60 seconds and I forced an update with my local NTP server. I can imagine I think what went on here but my guess is that systems adjust clocks on a pretty regular basis and if the app/cc is using that clock, as I think it may well be, then it could be the source of some strange behaviour. EDIT: Just checked the logs and when it did this with cpdn, boinc then picked up 2 seti units to run and did the same with them....and restarted those seti units happily. I have kept the log entires if anyone is interested. @Paul B If the clock can affect this way it may be a good one for the Wiki? Any one else seen this at all? Known already? Or is this just a conincidence do you think? <img></img><br><img></img><img> |
