Doesn't appear all that "Switched On" to me!
+1
EDIT: +1 refresh more works.

Now solved at Ubuntu 10.04.1 64bit - C2D 3.0GHz + 9600GT:
260.19.29 drivers CPU time about 20s, 256.53 drivers CPU time under 3s.
It looks like not too perfect app, but too perfect old drivers :-).

Interesting.
The propblem I solved as a beginner - by switching this computer to WinXP 32 bit. The same CPU, GPU (drivers 266.35) include OC, run time the same, CPU time about 4.5 - 6s.
The linux 64bit app seems to be too perfect, it should be coded more inefficiency :-).

I have tried:
- <avg_ncpus> to 0.3 and <max_ncpus> to 1 (two GPU tasks and one CPU task),
- to increase the nice of the CUDA processes,
- <avg_ncpus> to 0.5 and <max_ncpus> to 1 (two GPU tasks and no CPU task),
with no success.

9600GT has not sufficient memory for more than 2 CUDA CWPS tasks. I had to lover the <gpu_ram> to run 2 tasks...Load of GPU RAM was 90% when used GPU-Z to test 2 CUDA units in parallel.

No problems with workfetch but with validation.
We may have the ongoing problem that all WU's with a CPU-time
equal or below 3.00 seconds are marked as invalid

The same here.
ID 128555 9600GT + C2D 2.33 GHz @ Ubuntu 64bit CPU time > 3s for all tasks - all tasks validated
ID 131846 9600GT + C2D 3.0 GHz @ Ubuntu 64bit CPU time < 3s for most of tasks - all tasks with CPU time < 3s marked as invalid. I have tried all recomendations (<flops>, <ncpus>, <count> in <CUDA> part - 2 tasks concurently) but no succes. CPU time >3s I have got when I suspended and resumed the project only. Any idea?

You are right, it works fine using app_info.xml and manual sieving app, as did.

Task pps_sr2sieve_4945295_1 errored out with Maximum elapsed time exceeded. Host ID 10601 (XP x_86, HD4770). I thought 4945295 was from new batch having corrected that issue. I have used the stock app without any app_info.xml.

- So if it is the GPU task causing this problem, would making it separate from the CPU tasks solve this problem???
I mean it is due to very very bad adjusting of the GPU tasks's estimated time. The same problem switching the Boinc core to CPU panic mode AP26 CUDA tasks did. There is no way how to correct that issue on the user side as Boinc developers can't use two DCF for CPU/GPU tasks or two buffers (CPU and GPU operated separately). The only way is to adjust the estimate time on the server side corretly.

Problem solved, bad DNS run.
