21) Message boards : Number crunching : Sulphur Download? (Message 16656) Posted 18 Oct 2005 by old_user272 Post: My slow (750MHz) machine has just finished a slab model and downloaded a new Sulphur model which, I reckon, will take about 120 days to complete. Is there any point in running it?. I thought the idea was that the Sulphur models needed to be finished quickly so they could be used to seed the spinup models. IAn
22) Questions and Answers : Windows : MS Antispyware beta removed trojan downloader, Boinc Ceased working (Message 15554) Posted 30 Aug 2005 by old_user272 Post: > Just an update: the problem is resolved at this point. > From the restor point, I reran MS Antispware, removed the > trojan downloader again, and rebooted. Boinc started fine this time. > Perhaps the two issues were unrelated. Or maybe not. I installed MS AntiSpyware a week or so ago and since then, after a restart/reboot, I have occasionally had the "cannot connect" error. I can't remember ever seeing that error before. A reboot has always succeeded restarting BOINC though so I'm not too worried about it. Ian <img src='http://www.boincsynergy.com/images/stats/comb-942.jpg'>
23) Questions and Answers : Windows : BOINC backups (Message 15463) Posted 27 Aug 2005 by old_user272 Post: Thanks for the link. I have got Nick's script working but it appears the exit script can only close BOINC down if the manager is open and maximized on the desktop. If its minimized or in the icon tray then #AppActivate doesn't seem to work - and that's the way I normally run BOINC. It's a long time since I've used the WSH so I will have to have a refresher - there may be a way round it. Ian <img src='http://www.boincsynergy.com/images/stats/comb-942.jpg'>
24) Questions and Answers : Windows : BOINC backups (Message 15452) Posted 27 Aug 2005 by old_user272 Post: With the new loooong models that CPDN is issuing I think it might be wise if I changed my BOINC backup strategy - i.e. start having one :-) I\'d prefer an automated backup, in the middle of the night, but was a bit worried about folders getting out of sync because of the large amount of data being shifted about. i.e. 1) The main BOINC folder being backed up. 2) Something happens that causes client_state.xml in the BOINC folder to be updated. 3) The folder containing the file that caused the client_state change is backed up. In that situation the client_state file and the data file would be out of sync which might(?) cause a problem if the folders needed to be restored. Has anyone else addressed this possibility or is it not worth worrying about (always remembering sod\'s law). Is there an easy way of programmatically pausing BOINC while the backup is copying files?

25) Questions and Answers : Windows : Negative Credit (Message 14764) Posted 30 Jul 2005 by old_user272 Post: > It is possible you worked on some results that were unfortunately handed out > twice. The credit for these has recently been reassigned to whoever got > furthest with the model. This seems the fairest system. It doesn't seem to work that way in all cases. Have a look at http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=872375 This w/u was allocated to two machines. For the first one and a bit phases my machine (321 (187529 after a merge)) sent in the trickle first, after that the other machine (5336) got in the trickle first. I realised what was happening soon after my trickles stopped being recognised and aborted the model on my machine, leaving it to 5336 to complete. However, the above result still shows up in my result list and is missing from 5336's result list, even though that is the machine that completed the model. I haven't noticed a drop in my total credits so can only assume that I'm still being, incorrectly, credited for that model. Ian <img src='http://www.boincsynergy.com/images/stats/comb-942.jpg'>
26) Message boards : Number crunching : Trickles are great -- but how about some Credits? (Message 14710) Posted 29 Jul 2005 by old_user272 Post: > I suppose I could look for a result id and track back that way? - I never made > a note of any of them though. I went to my user page and looked through all the results listed for my username. There were results for computer id 321 listed but when I clicked on the "321" link it came back with the "Couldn't find computer" message. It looks like the result ids still refer back to the merged machines, and the total stats for the user are therefore correct, but there are no stats available for the merged machines themselves.

I tried to get the details for my old merged machine id (321) using the following but the server just came back with "Couldn't find computer". http://climateapps2.oucs.ox.ac.uk/cpdnboinc/show_host_detail.php?hostid=321 I suppose I could look for a result id and track back that way? - I never made a note of any of them though.

(Message 14704) Posted 29 Jul 2005 by old_user272 Post: > kenfins rac & total credit #'s (and probably a cast of thousands') should > be fixed now. Does this mean that the results for merged machines are no longer available?. Due to a double allocated WU I detached/reattached and then merged one of my machines (id 321 -> 187529). All of the results for 321 seem to have disappeared from my stats page - although the total credit I have is still correct. Ian <img src='http://www.boincsynergy.com/images/stats/comb-942.jpg'>
29) Questions and Answers : Windows : Benchmak stopped model being crunched (Message 14640) Posted 25 Jul 2005 by old_user272 Post: Just noticed the following in the log of one of my machines running hadsm3 4.13 25/07/2005 07:26:37 128 Suspending computation and network activity - running CPU benchmarks 25/07/2005 07:26:37 129 Pausing result 13pm_100072003_1 (removed from memory) 25/07/2005 07:26:39 130 Running CPU benchmarks 25/07/2005 07:26:47 131 Aborting CPU benchmarks, one or more active tasks are still running. I remember this happening once before on an earlier model and, I _think_, a different machine. The problem is that BOINCVIEW, and I suppose BOINC Manager?, show the model as running although it was never actually restarted after the benchmark abort. If you\'re not paying attention it\'s quite easy to miss the situation and end up with a machine sitting idle. Is this a known problem? Ian <img>

It is > allocated to your computer 321. 5336 started later but is computing faster and > has overtaken you. That makes sense. It would also explain why the WU doesn't show up in 5336's work list - I got it first :-) I suspended when I saw the problem and the machine is happily crunching another WU (it has a problem with 4.45 and an ever increasing short term debt, in trying to sort that out I had already downloaded another two WUs). I'll leave it in that state until 5336 finishes - but might not that machine have a problem when it tries to upload the result if the machine id doesn't match the one the WU was allocated to?.

33) Message boards : Number crunching : Incorrect credit allocation (Message 13860) Posted 26 Jun 2005 by old_user272 Post: Looks like the recent outage has caused another problem with misallocated credits. I wondered why the trickes from one of my machines weren\'t showing up in it\'s \"received trickles\" list (I know the rest of the stats are broken but trickle acknowledgement seems to be OK) and the reason is that the trickes are being allocated to another machine. Run ID - 872375 My box (321) shown as trickling up to 19th June Computer Id 5336 shown as trickling since then. What\'s the best thing to do? - I\'m tempted to abort the run. Ian

(Could that change when the servers feel better? Maybe) FWIW. I just looked through my results and found result ID 808760. The server has has only received 65 trickles but has a status of Over/Success - it appears to have missed 7 trickles during phase 1 without any ill effect. I also got exactly the same credit (6805.26) as models that were completed with 72 trickles. Ian

Why do you think you are in danger of "wasting" 346 hours. The only way that will happen is if you abandon the model or CP disappears for good (and, IMHO, that is very unlikely). Everyone seems to forget that trickles are completely irrelevant. You could download a model, get it running and only connect to the server again three (or whatever) weeks later when the model is complete - _never_ trickle at all. You would get exactly the same credit and CP would get exactly the same science as if you had trickled every day. I suspect there are people running CPDN on laptops who work that way. I completely agree that the lack of feedback is regrettable, to say the least, but it is no reason for abandoning the project. The only thing I would recommend, and I'm in this position at the moment, is that you don't let a model complete while the server is down - I've got one at 98% that I've just suspended and will only resume when the server is back.

Trickles are mainy for stats purposes and very little information is returned within one. If the server doesn't see a trickle then it doesn't matter. Stats are calculated on the amount of work completed, i.e. the timestep in the model, and you will receive the correct credit for _all_ the work you have done when the server gets the _next_ trickle from you. The only time (as far as I know) science information is sent back is at the end of each of the three phases, mainly the last phase. If the model completes, and the ~8 MiB of data generated is returned, the the full scientific value of the model run obtained, there is no wasted processor time at all. Trickes are _just_ so that you get some feedback from the model, your experiment would run perfectly well without them. > A simple news posting on the WEB explaining that there is a > temporary problem but that all data is still being collected would go a long > way with the volunteer community. Can't disagree with that at all. Ian

I have just rebooted the system and BOINC seems to be doing a lot more downloading (of work units on the other projects that I run) than I would expect. It may me that something had gone wrong my end and the reboot cleared it. It will be interesting to see if the missing trickes appear now. Ian
39) Questions and Answers : Windows : stats update still (or again?) doesn\'t work (Message 12269) Posted 4 May 2005 by old_user272 Post: > What is your host ID? I'd like to see that status for that PC. I might be seeing the same thing. I finished a run at 20:20 on the 2/5 and it uploaded correctly (I had already downloaded a new model). Since then the stats are showing no trickles for the machine which, as far as I can tell, is still crunching correctly. I would have expected to see two or three trickles by now. Host ID is 290. Ian
40) Questions and Answers : Windows : No work available (Message 10569) Posted 8 Mar 2005 by old_user272 Post: I had trouble downloading a new model this morning, for the same reason. However I successfully downloaded a new model at 14:00ish UTC, so if you haven't yet got one it might be worth trying again. Ian
