Yesterday I ran about 200 Seti tasks and now BOINC is not requesting any work. Got about 3 days work on AP. but not any other Seti tasks. For one day Einstein (that is running normal) The video card (CUDA) is now doing nothing. For some reason the CUDA tasks yesterday all ran in high p. mode without any reason, there was hardly any risk of running out of work.

There are several thread on the Seti board that touch on similar problems. Using CUDA is breaking the Boinc work fetch algorithm. The Work fetch policy will need to be completely rewritten as it currently doesn't take into account the GPU time and only sees the small percentage of CPU usage. Your DCF (Duration Correction Factor) for Seti has probably been thrown out of whack. You will probably notice that estimated completion time for the AP task is higher than normal. You may want to manually adjust the DCF, but I suggest first reading the Seti number crunching forum and seeking help there.

The AP times are not far from the actual run time 16 hours and it should be 12.
But now I have to delete a lot of AP tasks I still want to run and can run.
About 2.5 days of work with a setting of 10 day. And I get no more than 200 Seti task anyway. After deleting some more AP tasks I get some more tasks. And as the DCF runs down by a factor of 4 will get the rest of the work.
