I think my last model crashed once but it had to have been a fluke, I have used so many different aplications at the same time as the model and not had a crash, that I dont know when to expect one. Therefore if I am going to do a back up, it will probably be once a month, but my question is what needs to be backed up if I am to back up the data? And how should I back up the information? Should i just copy the files to a different location on my c drive? If your system is unstable with high cpu usage then good luck. I wouldn\'t do graphics intensive game while I modeled. That and make sure your computer can breathe. What does a crash look like for those of you who are having crashes? I\'m Sorry but my computer is perfectly stable. I can run climateprediction without problems for many hours. I tried prime95 with climateprediction 50/50 cpu time for 24hours without a problem. The problem is when an higher priority program require 100% cpu the climateprediction application get out of sync (remember that climateprediction run with a very low priority). I know it and now i stop boinc every time i know that another application will need 100% cpu time. There is a post also on the boinc dev\'s mailing list about this issue

I do backups only once a month - just before steping up to next phase! Until now, no problem at all with Sulphur 4.22 & Boinc 5.3.x under Linux (& yes, connected to the Internet 24/7). every time an application use 100% cpu for a while, the sulphur 4.22 crash. it can be a game or another kind of application, the result is the same a crash. I hope that after the BBC project release the dev\'s will correct this problem

Any explanations? you should post the workunits, we can\'t see your results page well, i think that sulphur 4.22 has some problems, i hope that the next experiment or next suplhur version will be more stable
6) Message boards : Number crunching : WUs constantly failing (Message 19936) Posted 3 Feb 2006 by old_user19523 Post: I occasionally run Doom while BOINC is running. The only problem is when it starts to benchmark. Then Doom slows right down and movement gets jerky. At least for me. The baddies seem to keep going. :( When/if I wake up to it, I suspend Doom until the benchmark is finished. Not every game eats 100% cpu, for example when i play with pes 5 the model continue to advance because the game doesn\'t need much cpu time :) many games simply do this: while (1) { continue; // :) }

I know this sounds like heresy ... but, not all project are suitable for all computers and all people. I have had decent luck running CPDN on all my PCs, occassional model crashes for various reasong, but, aa pretty decent track record. Heck I am about to complete my second Sulfur model in a coupld days (1 day 12 hours). But, though you would think that it would be a better computer to run CPDN I have yet to complete a model on my PowerMac G5 ... bad computer? Bad program, gremlins? who knows. But, I just stopped and now run other projects on the PowerMac, it really shines at Einstein@Home ... Again, this is the beauty of BOINC ... Oh, and WCG uses the UD program if you like, or you can run thier two projects under BOINC like I do ... For now i run climateprediction only in my home computer, where there is no internet access, it\'s the best project for a computer like this. I only have to backup boinc folder every day and once in a while transport with cdrw at work. in my friend\'s computer i\'ll install boinc with WCG and einstein i think, surely i\'ll not install climateprediction. I like this project but needs to much user attentions. BTW with my home computer i managed to do an old slab model, without backups and with a lot of gaming ;) http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=250218

Yes i know it, at least for climateprediction. But you, I and several thousand of people can do this, but there are millions out there that can\'t do this. To let the boinc platform be more attractive to normal users, must be more reliable also if you are playing a game :). the average computer user, is capable to surf in internet, write an email and to install a program, of the other thing he doesn\'t care. I look on the forums, in the server status, results page and so on several times in a day, you can say that I\'m a boinc addicted person :) An example of an ipothetical non expert user. 1) one friend tell him that can use is spare cpu time for something usefull. 2) He thinks \"why not?\" 3) install the boinc client (if he is capable) 4) He choose the projects he likes (now is better than before, but i\'m waiting for account managers :) ) 5) He is sure that it don\'t need his attention and he forget about the boinc existence for a month 6) after that because for 1 Hour a day plays his favourite game, in a month has lost 30 climate models,lost time, wasted server resources, and no science done. 7) Deleted boinc and user lost. My first DC project was UD, and i liked of it that it was an install and forget program, then over 1 year ago i switched to boinc because i liked its philosofy. To make an example, I keep the UD client on a friend\'s computer where i have very infrequent access. I would like to install boinc as soon as i can, but for now to manage a remote client with dynamic ip it\'s a ** * * P.S. I\'m sorry for my bad english :(

I have no power supply problem, i have an enermax power supply(i don\'t remember the model :) ) no problem with the cpu overheating, i\'m using hyper 6 from cooler master, 950g of laminated copper :) I have latest stable drivers of everything, andthe system is completely stable I\'m running boinc version 5.2.13. with normal installation (no service) with automatic start Os Windows Xp pro SP2 without any additional update. How to reproduce these issue, it\'s simple: 1) you need a brother (maybe it\'s not strictly necessary :) ) 2) turn on computer. 3) wait until the logon of windows appear 4) logon 5) Start a standard game, in this case Splinter cell 1 6) After 30 min or 1 hour you exit from game 7) Model crashed This weekend i\'ll try to reproduce the model crashing myself to gather more specific details. And i want to try also if i can reproduce with another computer.

12) Message boards : Number crunching : WUs constantly failing (Message 19684) Posted 27 Jan 2006 by old_user19523 Post: You could try removing BOINC from the startup folder, so that, when your brother turns on the computer to play games, BOINC doesn\'t start. When you want to run BOINC, start it manually by clicking on the boincmgr icon in the BOINC folder. Yes i know :) But for now it\'s fine in this way, i make a boinc backup every morning ;) I want to keep the model crashing, so maybe i can find something useful to help programmers fixing issues like this. Because avoiding the start of boinc, or to make a backup is a suitable way for expert people, not for the normal user. In special mode when the workunits last several months :) Now i have to find a way to avoid the cleanup after the model crash, to find the error in the yabds.out. In the working model, in yabds.out there are errors similar to those on db\'s post, if i remember i\'ll copy them here tomorrow.

I\'m glad that i have not an internet connection at home ;) My system is stable, i tried with prime95 and climateprediction for 18 Hours (50/50). and also with memtest86+. maybe there is a problem when the model start and don\'t reach the first checkpoint because there is an evil game that eat every cpu cycle ;) P.S. I can see this morning that my english is worse that ever ;)
