I\'m not certain exactly what is happening, but my system is crashing when I run the CPDN model.

I believe I\'m running the sulfphur model--it looks like rev 422 or 4.22 from the files in the CPDN directory. The program is causing an odd crash of my system. After kicking off a model run, when I wake in the morning, the display is not responding correctly. The widgets are \"missing pieces.\" Task manager won\'t launch. So, I can\'t confirm which program is running. That\'s my best description.

SETI@home does not cause a problem. It\'s been running fine since I switched to BOINC last month. However, whenever I run the CPDN model, my system will crash. This requires several hours to occur, though.

I\'ve isolated the problem to the CPDN software. When I first started the CPDN model, I experienced this behavior. I then restarted the computer, shutdown the CPDN model, and left the system running. My system ran fine for a couple of weeks.

Last night I re-enabled the CPDN model. When I woke this morning, the system was partially responsive. Task manager would not start and the CPDN model had crashed (it was missing from the BOINC manager work tab.

This behavior sounds like a memory leak to me. Memory is being allocated but not released properly. After some time, both the swap file and physical memory are completely used up and the system can no longer perform.

All is fine when I shutdown BOINC and reboot.

It has to be the CPDN model because the system is stable when NOT running the CPDN model.

I would like to contribute to the model experiment, but I can\'t use a defective code.

I am not trying to flame you in this response, but it is quite a presumption to blame the code for your troubles given the number of people running CPDN at the mo without these problems.

I see that you are running with an AMD and 1GB ram.

Are you stable in prime95 for at least 24hours?

How are your temperatures at load?

Some people have driver/anti-virus conflicts.

Remember CPDN is harder on hardware than most other applications.

Why thank you. I\'m not totally ignorant with respect to computer programs having written and run many numerical models over my 30-year career in engineering.

With this response, I\'ll just excuse myself from the project and spend my time and computational resources on other project.

Nice try Jimmer. Some people just won\'t be helped once they think they have figured out the problem is not their computer. As you pointed out, lots of people run this project with few or no problems. Doesn\'t sound to me like \"It has to be the CPDN model because the system is stable when NOT running the CPDN model.\" It sounds like some interaction between cpdn and either a virus software or perhaps some driver if the visualization is running.

Ahhh well...

I am having problems with the sulphur model as well. I leave it running over night but in the morning when i wake up, my system is completely blahhhh. I usually run azureus at night and thought that this might be the problem but having left the system azureus free last night, i have come home from work just now to find the system all jammed up once more.

Advanced vis will not run on my system so its not that.

I have turned off antivirus and anti spyware, same result.

Any suggestions?

Oh and one last thing, I really did think that your asinine behaviour toward the person originally posting this query was right out of line. Perhaps you can save your self righteous and caustic sarcasm for the real world where at least your targets will have the opportunity to smack your jaw lose for the tacit insult.

Something to ponder perhaps?

When you say blahhhh, what do you mean? Sluggish? Jammed up in the way that ruminator described with the display not responding?

I wasn\'t very clear as to which visualization I was talking about. I meant the built-in visualization which can sometimes be problematic with some video drivers. I don\'t think the Advanced viz runs on any PC right now.

I have turned off antivirus and anti spyware, same result.

Anything else running? Are you running multiple BOINC projects? I\'m just wondering what\'s happening since the sec/TS for PC is rather high for a 3.2 GHz P4. Something else would seem to be using a decent portion of CPU time.

Any suggestions?

Nope, just questions at this point.

And I thought ruminator\'s response to Jimmer trying to help was out of line. While I understand the frustration, numerous people don\'t have this problem. So while climateprediction can be implicated as part of the cause, a statement like \"It has to be the CPDN model because the system is stable when NOT running the CPDN model.

I would like to contribute to the model experiment, but I can\'t use a defective code.\"
would imply to me that this is some basic flaw in the program that should be affecting many people, while it looks like some interaction between cpdn and some other process or configuration on that PC that most people don\'t see. Obviously checking the forums here one can find lots of people with lots of problems. Some are hardware, some are software, some are drivers, some are BOINC related, some are cpdn specific. The questions Jimmer asked were, and the point he made was, valid.

HEY THANKS FOR THE PROMPT REPLY.

IM NOT YELLING JUST MAKING IT EASY TO PICK THE REPLY FROM THE POST.

When you say blahhhh, what do you mean? Sluggish? Jammed up in the way that ruminator described with the display not responding? THE DISPLAY RESPONDS BUT FOR SOME REASON MY ENTIRE SYSTM JUST MOVES INCREDIBLY SLOWLY AS IF SOMETHING ITS CHOWING DOWN SYSTEM RESOURCES. NOTHING SHOWS UP THOUGH. IT IS ALSO IMPOSSIBLE TO RUN ANYTHING AT ALL AFTER THIS. ITS AS IF THE WHOLE SYSTEM HAS FALLEN DOWN BUT IT STILL GOES THROUGH THE MOTIONS OF WORKING.


I wasn\'t very clear as to which visualization I was talking about. I meant the built-in visualization which can sometimes be problematic with some video drivers. I don\'t think the Advanced viz runs on any PC right now. I WAS TRYING TO RUN THE ADVANCED VIS V3.0. I FOUND A POST SAYING IT WAS A KILLER FOR A LOT OF PEOPLE AND THE PROBLEM WAS BEING ADDRESSED.

Anything else running? Are you running multiple BOINC projects? I\'m just wondering what\'s happening since the sec/TS for PC is rather high for a 3.2 GHz P4. Something else would seem to be using a decent portion of CPU time. NOTHING I CAN SEE OR THINK OF? IM SORRY, IM NOT CATCHING YOUR MEANING IN THE LAST SENTENCE. DO YOU MEAN THAT MY SYSTEM IS RUNNING SLOW FOR A P4, 3.2? I FEEL THAT ALL THE TIME.

GRANTED, THEY WERE AND IM NOT SAYING FOR A SECOND THAT ITS A CODE BASED PROBLEM, JUST SIMPLY A APPS CONFLICT.

I THINK THAT A LOT OF PEOPLE WHO VOLUNTEER TO ACT AS ADMINS ON THESE FORUMS DO SO BECAUSE IT ALLOWS THEM TO FEEL IMPORTANT, A BIT LIKE THE KEEPER OF THE ESOTERICA. IM SORRY BUT PART OF THE ORIGINAL POST, TO MY MIND, WAS SIMPLY RUDE. I APPRECIATE THE HELP I RECEIVE ON THESE THINGS BUT I DONT LIKE TO SEE ADMINS INSULTING CONTRIBUTORS. I THINK IT RANTS.

If it\'s really slow, perhaps your cpu is seriously overheating, and running into \'thermal throttling\'. Have you had a look at the heatsink to see if there is any dust on top? It doesn\'t take much to cause problems.

I will not participate in an ongoing flame war so I will not post in this thread beyond this response.

I clearly asked pertinent questions and since I only have 30 or so posts I think the backing of a moderator was appropriate to emphasize points and stress to the original poster that I was not talkin out of my a$$.

As far as your insult to geophi, I think you were way out of line, to me his post was not asinine in any way, to imply physical conflict as a solution to a computer \"geek\" problem is just bizarre.

if you go back to my original questions

Are you stable in prime95 for at least 24hours?

How are your temperatures at load?

Some people have driver/anti-virus conflicts.

Remember CPDN is harder on hardware than most other applications.

you may find your answer.....

You can\'t help yourself can you? Perhaps its best if you dont contribute then. What point do you think it serves to try and make someone feel small by saying something like that? As a mod or a veteran poster you should know better!! What is this forum about? Small people making themselves feel better by insulting contributors?

I dont have the time to locate the original reply posted to the individual who fist cited this problem. It was rude nonetheless. So rude in fact that it prompted said poster to leave the forum and the project.

Simple.

NOTHING I CAN SEE OR THINK OF? IM SORRY, IM NOT CATCHING YOUR MEANING IN THE LAST SENTENCE. DO YOU MEAN THAT MY SYSTEM IS RUNNING SLOW FOR A P4, 3.2? I FEEL THAT ALL THE TIME.

Yes. A system like that in WinXP should get about 3 sec/TS or less. The trickles on the \"Your account\" page show 3.7 or 3.8. Something else is using considerable CPU resources. It may or may not be causing the problem in conjunction with cpdn, but it is suspect. If you open up Task Manager while the model is running and sort the columns in the Processes tab by CPU, it may say what else is using up CPU resources. You don\'t have an OpenGL (3D) screensaver running at night do you?

While stereotypes often have some kernel of truth to them, it is hard to see how that applies in this case. I didn\'t volunteer to become a moderator, it was given to several of the forum regulars last week to combat spam and some crazy hate speech posts recently. About the only bonus I see to it for me is the ability to make Stickies (long needed) and to edit my own post after the one hour time limit is up for others.

Don\'t worry Jimmer, I\'ve got my eye on this thread and certain posters.
After the previous recent problem where I got help from Carl, and he created several moderators, I\'m not in the mood to put up with bad behaviour.

hey. thanks again for the response. look, i have checked the task manager and i have nothing going on while BOINC is running. no screen saver, no anything at all. i still woke up to find my system had fallen over again last night.

i really do need to run certain apps while i am asleep and boinc seems to be messing with my back-ups as well (third party off site) so i\'m going to suspend it on this pc until i can have it play nicely with my system. the only reason i say that boinc is my suspect is because i have had 12 months of happy, happy, joy, joy on my system without it and 5 nights of no work with it.

sorry about the stereotyping.

For some reason, a number of people couldn\'t get BOINC 4.25, or 4.72 to work. (It may have been to do with AV, or ATI cards; forget now.)
So they reverted to 4.19, which may also work for you. And if it does, may give a clue to the problem.
All versions of BOINC are available <a href=\"http://boinc.berkeley.edu/dl/\"> here.</a>
