My system is:
CPU: Intel Core Quad Q9550
GPU: Nvidia GTX 460
OS: Ubuntu 10.10 x64
BOINC: 6.10.58

My problem is: I'm crunching for Einstein@home and each time BOINC reports completed GPU WU, it requests new WUs for both CPU and GPU.

Чт. 17 февр. 2011 13:37:19	Einstein@Home	Sending scheduler request: To fetch work.
Чт. 17 февр. 2011 13:37:19	Einstein@Home	Reporting 1 completed tasks, requesting new tasks for CPU and GPU
Чт. 17 февр. 2011 13:37:22	Einstein@Home	Scheduler request completed: got 2 new tasks

GPU's WU takes 1 hour to complete, CPU's ones are 4.5 or 15.5 hours, so each hour BOINC requests additional 10 hours of CPU work time in average, even on 4 cores it can't be completed in 1 hour, so in day or two i collect huge amount of CPU WUs, that would take about two weeks to complete.

So the only way to stop incoming WU flood is to suppress WU fetch and GPU computations for a couple of days and crunch only CPU WUs.

This sounds like a problem which has been niggling Einstein for some little time now - see the thread Scheduler went nuts on the Einstein message board.

It would be most helpful to compare detailed client and server logs for your machine, to try and track the problem down. But I can't find a user called "Zarbis" at Eintstein, so I have no way of tracking down your computer, either.

Perhaps you could identify yourself in that Einstein discussion, and we can take it from there?
