Hi,

I seem to be having trouble running the Sulohur cycle experiment - I\'ve had several models all crash within a few days. Is there anything I can do to improve their chances?

I\'m running Bonic vn 4.45 on XP.

Cheers

The following *may* help, although they\'re just guesswork at this point

* Update to Boinc 5

* If you use Norton Antivirus, Sophos, then add the Boinc directories to the exclusion list

* Test your system with Prime95

* If you see a microsoft \'Send/Don\'tSend\' dialogue, don\'t select anything until you have killed the various boinc processes.

Is there anything interesting in the \'messages\' tab?

BOINC 4.45 has at least 2 bugs which cause problems with this project, so it\'s not recommended.
Follow the advice of MikeMarsUK and upgrade.

Then follow his other advice.

Hi,

I\'ve upgraded to Bonic 5.2.13, but I\'m still not getting anywhere.

I have no control over the anti-virus software as its a networked machine and that is done centrally.

What is Prime95?

The latest message tab reads (and seems to be the same every time):

I\'m also running CPDN classic at the same time - could this be causing any problems?


Any further suggestions gratefully recieved. I never seemed to have these problems before switching to the sulphur model.

It is a pity that you have no control over the anti virus software, as there is a possibility that is the culprit, though I agree that it is odd that the problem did not manifest itself before. There is a report of Sophos AV software crashing the program because it has detected a sequence of code it thinks wrongly is a virus, so these things can hit you out of the blue.

On Prime95, there is an explanation here. You will see it is a popular way of stress testing a computer.

Please excuse the last post repeating a previous one. I hit the post button accidentally.

I am experiencing the same problem. I am running both the BBC experiment and sulphur, and both models have crashed, separately. I\'m running BOINC 5.2.8 on an Athlon 64 3200 with 2g of memory. I do have control over my AV software (Norton), but I\'ve been running the climate experiments without any problems for almost a year until I started running the BBC experiment. This is the latest crash message sequence. Notice that the sulphur model crashed AFTER it had been removed from memory to restart the BBC model:

> Unrecoverable error for result sulphur_hbtw_100808484_1 ( - exit code -1073741819 (0xc0000005))

Note the exit code. It gets talked about a lot, with no definitive cure. However some people have fixed it with an update to their graphics card drivers.

Making a guess: You didn\'t look at the vis much with just sulphur, but have looked often with the new BBC model?

Leaving in memory has also helped a few people, and is usually recommended.

In addition to the above suggestions, here are some other ideas for reducing crashes :

I would recommend the following :

* As suggested earlier in the thread, if you use Norton or Sophos antivirus, exclude the boinc project directory from the automated scan.

* Before playing games etc, set \'no more work\' and \'suspend\' the model - that way they won\'t tread on each other\'s toes. Sometimes simultaneous use of graphics drivers from two different programs seems to cause problems.

* Run a stability test on your machine, I recommend Prime95 from www.mersenne.org (the \'torture test\' option). Run it for about 24 hours. If this fails, then there may be problems with overheating / overclocking etc, cleaning out dust from the motherboard and fans often helps if this is the case.

Thanks! Definitely linked to graphics. I updated the graphics driver; also stopped using BOINC screensaver. No more crashes. (I have an ATI X700 PCI-X card on XP)
