Ok, what\'s the deal with BBC and CPDN?

I recently reattached to CPDN after a reformatting, but although I never signed up for the BBC thing, it\'s the BBC that is now running (for it\'s designated part of BOINC time). Don\'t tell me it\'s just CPDN in the coat of BBC, because the other thing is that the model is trying to report back to BBC (get\'s blocked by the firewall for various reasons - yes, I control the firewall). And when it can\'t get through it crashes.
I have the BBC screensaver (which is another joke, because it tells me to press such and such key for this and that animation, but if I press the key, it wouldn\'t be much of a screensaver left, now would there!?).

I\'m quite fed up with the whole thing and considering detaching the whole project, giving my other projects that CPU-time.
(Because it does compute for a while, but I never get credited because it cannot report back).

If have done some searching but it doesn\'t answer all my questions, in brief;

1. Why does the CDPN model run as BBC?
2. If it\'s just CPDN with different colour, then why does it report back to BBC?

I want to run CPDN, NOT BBC. :)

Once upon a time, a long while ago, (2005, actually), the BBC decided to do a television series on climate change.
To go with this, \"they\" decided to also see if it was possible to run a climate modelling program, and so was born \"The BBC climate change experiment\".

Because the BBC wanted to involve the entire British public, they insisted that everything had to be made very simple and easy to use, and so a special version of BOINC (5.3.19), was created to automate the \'join a project\' part. The programs were installed in a different folder name to the normal BOINC location, for reasons that are unclear, and which has caused a lot of problems for people upgrading from the special version, or who attempt to join the project while already running aother DC projects.

And the new climate model that was nearly finished being tested, was chosen as the model for the BBC cce, with new graphics having \"BBC\" in several places.
The BBC also paid for another server or two, which has a url containing \"bbc\", but which is physically situated in the same comms room at Oxford Uni, as the cpdn servers.

This project was launched on Valentines day, 2006, to much fanfare and hype, and, \'after the dust had settled\' a few weeks later, the exact same model was released on cpdn, to replace the then current \'sulphur\' model.
The graphics also contained the letters BBC, so as to avoid any problems with creating and testing a new graphics package, although the identifying names for these cpdn models were (and still are), slightly different to those of the BBC models.

The BBC\'s involment with climate modelling finished in January, but the servers, the bbc url, and lots of \'BBC\' models still exist, and will continue to do so until some time later this year.

However, now that the BBC is no longer involved, a new graphic image has been created without \"BBC\" in it for all new cpdn models that get issued.

If you\'d like to restate your problem in a calmer manner, help will be forth comming.

Backups: Here

A more serious problem is that his machine is crashing models very quickly, a new one every day. They seem to be at random times, so I don\'t think it could have anything to do with blocking project servers? Only two have got to the point of uploading trickles. 3s/ts also seems rather slow for the machine spec, perhaps this may indicate an unstable (overclocked) PC. Running Prime95\'s torture test for 24 hours would help to eliminate this possibility.

Cronos, you have had cpdn models. If they progress far enough to trickle (on or after 4 Dec of the model year) they are trickling to the cpdn server, so communication with the server isn\'t a problem.

Most of your models have crashed with -107 error codes but there\'s the occasional -1 crash. I expect there\'s a graphics problem and would suggest:

*Set the screensaver to None and look at your globe when you want to through the graphics button in boinc manager. Don\'t maximise the graphics window.

*Look at the READMEs through the link in my signature. You don\'t need to read everything. In the Running the model README, check the top tips.

*In the README about avoiding model crashes, read link #5 by Mike which includes specific advice for avoiding -107s.

*Same crashes README, link #5 by Thyme Lawn about updating your graphics card driver, which means a free update from the web. Doing this can also help prevent -1 crashes.

*When your model is running stably without crashing, Check item #1 in the crashes README. Here Les explains how to back up your model so that if you do have another model crash, you can restore the backup and continue with the same model.

*Make sure you always exit from boinc before you close down the computer, but don\'t exit boinc using Task Manager.

Ok, guys. Thanks for enlighting info.

Let me give you a piece of valuable info. Upon reformatting of pc, I DID have some driver issues (ATI card) (for some weeks now), but I reinstalled driver and fixed this just a couple of days ago, so this might fix at least some of my problems?

Another piece of info is in my log;
\"Task hadcm3ohe....... exited with zero status but no \'finished\' file.
If this happens repeatedly you may need to reset the project\"

And then a bit later \"Restarting task hadcm.... using [snip] version 515\" (I guess this is just a regular message)

If the \"zero status\" message is infrequent, it can be ignored. One potential cause is Windoze resetting the system clock and causing boinc\'s eyes to glaze over, so to speak. No need for Project Reset. (If you search the Boards for \'zero status\" you should find plenty on it.)

Others have been helped through -107... crash problems with an updated graphics driver. Suspending boinc before engaging in heavy-graphics activities (some games, photo/video editing) is another \"protect myself\" measure.

Greetings from coastal Washington state, the scenic US Pacific Northwest.

The most recent model has successfully trickled back to the server, so as Astro says the driver update may well have sorted it out (fingers crossed, anyway).

Ok, I have finally been credited again!
This is the first credit in a long while, after the model had run without crashes for some time.
I still have the BBC screensaver, but as long as this is due to change in the future, and as long as I am credited for CPDN, I am happy for now.

Thanks for the help, guys. I will let it run and get back to this thread if anything.

Cheers!

Get rid of the BBC overlay on the graphics by clicking Z then 8 on the keyboard. 8 then Z restores it.
