I\'m running BOINC 5.8.15, WINXP SP2, and have had CPDN porjects in the past; but about six months ago, i stopped receiving them. I\'ve changed my prefs to the lowest usage project (UK Met Office HADSM3) and yet, BOINC still hasn\'t downloaded a new project. I was wondering if this has happened previously to others and what, if any, steps I can take to rectify the problem and start receiving new projects again.

Thanks,
Grizz.

What are the messages in the Messages tab when it tries to request work?

Is there a climate model in the tasks tab?
If so, what is listed for it under Status?

There\'s no model in the TASKS tab and hasn\'t been for about 6 months.

And yet the message says: (not requesting new work or reporting completed tasks)
So the question is: WHY isn\'t BOINC requesting more work.

In the Projects tab, what does it say under Status for the climate project?

Les is concerned about the \'No more tasks\' option, which is the most likely cause for your problem.

But there is a second possibility which is that the Boinc manager is paying back \'debt\', - what are your resource shares for the climate project compared to other projects?

The reason that I ask is that people with many projects often run into an issue where the climate model gets priority for a while over the other projects due to the low resource share putting the model\'s deadline at risk. As a result, the model gets much more than its fair share of time. Once the model has finished, the other projects get \'paid back\', by being given priority in return. This can be for quite an extended period of time.

CPDN has nothing written in the \"status\" section on the projects page.

Resource Share is at (100)12.50%, i have 7 other projects, 6 of which are \"active\"(not all of them have tasks for me to perform; ie lhcathome), 1 \"suspended task (NANOHIVE), with an average of 3-4 tasks on my pc at a time.

This \"debt\" you speak of sounds most likely as I have 14878.08 \"work done\" points for CPDN and the closest other project is Einstein@Home, which is currently at 6812.00 \"work points\" done. I had noticed that CPDN was running quite long sessions (in excess of 2hrs at a time) when it was running on my pc, whilst my other projects seemed to cycle at 1hr intervals. Having said that, is there a way to \"lessen\" this debt or do I just have to wait until the other projects \"catch-up\"?

The best thing to do is just to wait for everything to equalise, although you can speed the process up by increasing CPDN\'s resource share (so rather than being given 1/7th of the CPU time it is given more. This will pay back the debt quicker).

I read somewhere that, because of the long WUs here, giving the climate projects less than about 40%-50% meant that they had problems.
This was some time ago, and I don\'t remember the details, but it\'s possible that BOINC won\'t even try to get any new models until cpdn gets a bigger time allocation.

I understand that by increasing resource share, CPDN will run more effectively(when I have CPDN projects), but how does it reduce the debt seeing as I have no CPDN projects running? I thought that the other projects needed to catch-up by running until BOINC determines that the debt has been re-payed.

ARGH, it\'s all too confusing right now, I\'ve just woken up and am still having my morning coffee. I\'ll come back when I\'m more awake LOL

If you increase the resource share the other project\'s debt to CPDN will diminish faster and BOINC will request a new CPDN task sooner.

If you increase the resource share the other project\'s debt to CPDN will diminish faster and BOINC will request a new CPDN task sooner.

I\'m still not quite sure how that would work... wouldnt increasing CPDN\'s resource share INCREASE the debt?

I know that I probably sound like a complete idiot not knowing how/why this would work, but I thank you all for helping thru this. I look forward to each reply, cuz they all help me get one step closer to re-starting CPDN projects.

UPDATE: I have JUST up-ed CPDN\'s resource share to 500(41.67%), of course I haven\'t seen any changes just yet.

If you\'re really keen to get started on a new model, you could temporarily suspend your other projects in the Projects tab and their tasks in the Tasks tab.

You\'re also more likely to be sent new work if you increase your work buffer (the max allowed is 10 days) in the BOINC manager Advanced menu. In the menu you need to go into the Preferences window to edit the buffer. If that works, it might be a good idea to reduce the number of work buffer days again before you unsuspend your other projects and tasks. Otherwise you may find that some of them send you more extra work than you really want.

UPDATE: I have JUST up-ed CPDN\'s resource share to 500(41.67%), of course I haven\'t seen any changes just yet.

The debt will drop at roughly 20 credit per day (your total RAC of 48 multiplied by 0.41). I don\'t recall how to get the debt to display, perhaps someone could explain this...

Isn\'t there a BOINC add-on that displays debt?

Edit: There\'s the BoincDV add-on here:

http://boinc.ssl.berkeley.edu/addons.php

but it looks as if it\'s for version 4 of BOINC, which no active CPDN members can be still using.

I\'ve just downloaded that to try it, and it does seem to work (negative debt figures are where the project is working off debt back to other projects, positive is where a project is owed time by other projects).

First you extract the files from the ZIP, then run the \'BoincDV\' executable. Enter the path to client_State.xml via the \'Load\' button, then you get a display such as the following one:

STD is the short-term-debt, which controls which of the projects which already have work on the PC should have their turn next.

LTD is the long-term-debt, and controls which project should have new work downloaded from the project servers next. I guess the numbers are seconds, but they could be something else.

RSRC is resource share.

If you add up STD or LTD, the total should be zero.

There is also a \'reset debt\' button, I don\'t know if it\'d be safe to use that given that BoincDV is written for an older version of Boinc, so if you do try it, make a backup first!

Excuse me if I\'m being a bit dim here but, if he\'s getting the message \"not requesting new tasks, doesn\'t that mean he\'s pressed the \"no new tasks\" button in BOINC manager? I\'m not crunching at present and so can\'t look to see, but I seem to remember people getting confused because when the button says \"no new tasks\", you are in fact requesting new tasks, whereas, when it doesn\'t, you aren\'t!

Not necessarily, if you click \'update\' but the manager doesn\'t want to download more work, you\'ll get that message. The tricky thing is to try to work out why...
