I\'m not getting any new CPDN WU\'s and the ones I DO have on my computer are not running. I currently have almost 2 gigs of CPDN work stored on my computer and it\'s not doing anything. This has been the status for about the last month. I have \"updated\" CPDN several times and get the following response:

12/1/2007 12:01:36 AM|climateprediction.net|Sending scheduler request: Requested by user. Requesting 0 seconds of work, reporting 0 completed tasks
12/1/2007 12:01:42 AM|climateprediction.net|Scheduler request succeeded: got 0 new tasks

I checked the server status and it shows all services are running normally (green). Can anybody explain to me what is happening? I am currently running 12 total projects and almost all of them are running normally (Predictor@Home has also stalled, but according to their website the project is not sending any new work)
If anybody can help me with this, I\'d sure apprieciate it. -=Guy=-

If the stored data is from old models, either finished or failed, they can be deleted.
The original slab models kept data for future use, and failed models don\'t get to the clean up part of the program.

As you\'re running a lot of projects, it\'s possible that BOINC is in \'pay back\' mode as far as the climate models are concerned. You can check this by setting all projects to No new tasks in the Projects tab, and then suspending all models/WUs other than climate models, in the Tasks tab. One of the climate models should then start running.

I\'m having similar problems. I support three projects, one hasn\'t got any work at present, one is giving normally and climate prediction absoutley nothing. I have spare computing capacity here, but don\'t really want to sign up to anyother project as too many can sometimes mean missed deadlines when everything is working.

Any news about what could be causing CPDN to stop giving out work would be welcome

A model seems to have downloaded now (here).

The models on that machine don\'t seem to have made much progress before crashing. Some have been aborted, but others have failed with a \'-107 error\', which is sometimes graphics related. Judging by the PC performance relative to the time between trickles, the machine looks as if it\'s used intermittently: if that\'s the case then it\'s a good idea to suspend the model before closing down.

An explanation of problems that cause models to crash is here.

Best of luck.

Thanks Les,
I did what you suggested and 2 CPDN WU\'s then downloaded and started running. (my computer runs WU\'s from 2 projects at the same time) After they downloaded, I then went back to my normal settings and I now have the following in my BOINC manager tasks window:

1 project ready to report,
2 projects running,
4 projects waiting to run,
4 projects waiting to start (2 of which are CPDN)

Now do I need to \"clean up\" the old CPDN tasks? Or just leave it as is? How do I find the old ones and delete them, and leave the new ones intact? I have almost 600 gigs of HDD space so it\'s not really a space issue but if they are not needed.....
Thanx again for your quick response, it\'s much apprieciated. -=Guy=-

If you set \"No new tasks\" for climateprediction along with all of the other projects, then you should NOT have received any new climate models. The ones that you DID have should have started to run, which was the point of what I posted.

And you should clean up the old models.
Write down the names of the models that you currently have.
Then look at the folders of all the climate models.
Those not on your list can be deleted.

Sorry I misunderstood your post Les.
Now I assume it\'s too late to do anything except run the 2 new ones I recieved, since suspending them and selecting \"No new tasks\" will shut down the whole thing right?

I did find the folders with the new WU\'s names on them along with several others. Would I just need to delete the entire folder for each of the other models? What about all the other files I found that are not the new WU\'s? There seems to be a whole lot of them scattered around within the projects folder labled climateprediction.net (D:\\Program Files\\BOINC\\projects\\climateprediction.net)

In that folder, there is a total of 7 folders, 2 of which are the new WU\'s and 4 others plus a folder labled txf (which is fonts) and 62 other files with various extensions such as xml, gz, png, zip, and exe. as well as a few files with no extensions. I understand most of those are for the program to run so I should just leave those as is and just delete the 4 folders not related to the 2 new tasks correct?

Thank you again, -=Guy=-

Hi LadyzGuy

I don\'t think you should delete anything at all from the boinc folder before making a backup of the entire folder. There are instructions about how to back it up in the CPDN READMEs which can be reached through my signature. I just use Les\'s easy manual method.

Les is confident about deleting old models from the boinc folder but I don\'t want to have to do this. An alternative way to occasionally clean out remnants of old workunits from any project is this:

* Before a project\'s last workunit has completed, set that project to No New Tasks.

* When that last workunit has finished, uploaded and reported (ie completely disappeared from the Tasks window), highlight the project and click Reset. This deletes unnecessary old task files.

* Click Allow new tasks to get a new workunit.

Obviously one can\'t do this while running a task as it would be lost!
