I normally ONLY run CPDN. In only attached to a second project after this problem started, to see what the behaviour would be. Even with all other projects disabled and with only 1 task (the single CPDN job it is running) it simply refuses to download additional CPDN work.

BOINC 6.2.19 on a different PC does not exhibit this behaviour.

UPDATE: Upgraded to BOINC 6.6.20 and it immediately did what I expected, i.e. realised it needed more work and downloaded the tasks.

Wonder if my problem was related to the change to HADAM3P 6.06?

I have done all these things on my BOINC 6.4.7 - both on the client and in my web site settings.

I have one cpdn job with over 1,000 hours to run.

My other cpdn job finished.

Since then BOINC will not request another cpdn job ("requesting 0 tasks"), but if I connect to a second BOINC project, it immediately downloads jobs and starts running them on the second core.

Change my BOINC version maybe?

Disabling enables you to suspend one or more tasks without BOINC downloading more.

I mentioned this in case all three of your current models were being processed alternately. This would allow you to complete the 2 that have been running for a while, and THEN starting the long model.



Thanks Les - that makes sense. Appreciate your feedback.

Cheers

Thanks Les and Hagar. I artificially downloaded a model a bit early (40 odd hours to go on one job) to make sure I didn\'t run out of work on this PC, as it has its Internet access blocked most of the time (my son finds the Internet very distracting from his studies).

What difference does disabling new tasks make? I normally have a 3 day work buffer and only run climateprediction.net on this PC. I would have thought BOINC would not do anything until I had less than 3 CPU days work remaining?

Cheers

Hi

I just received a job

HadCM3 Couple Model Experiment Optimised File I/O 6.04

hadcm3istd_cq3q_1920_160_06017962_2

which, while it has not started running yet, is estimated to require 9060 hours to complete (just over a year of 24x7 crunching).

I don\'t have a problem with this; but is it normal?

Cheers
Adrian
