Is anybody monitoring the work-fetch reports at SETI (likely high take-up of v6.6.2 because of their CUDA application)?

1) Server somestimes sporadically issues far more work than requested - SETI message 855982 and confirmations.

2) Server issues work when 'No New Tasks' in effect - reported here at BOINC Dev.

3) CUDA work requests don't take account of cached work already received - keep requesting the same amount until daily quota reached - SETI messages 856650, 856622

4) Server won't issue plain, bog-standard CPU work to a plain, bog-standard BOINC client (v5.10.45) - SETI message 856753. Backward compatibility, anyone?

v6.6.2 definitely should never be upgraded beyond Beta.

I can confirm that BOINC 6.2.19 also gets work when its not requested. See log below. All projects were set to NNW. I was trying to report a task. As you can see it still gets work despite not asking for any. Seeing as 5.10.45 is doing the same thing this would suggest the bug is on the server side as BOINC hasn't been updated.

Using 6.2.18, and running cpdn, when I report a task with NNW set, NO new work is downloaded.
So the problem may be specific to SETI.

Yes, I'm sure it is. But it's the frantic tinkering with the BOINC code base (to enable BOINC to support CUDA) which has allowed bugs like this to creep out into the wild.

Coming soon to a server near you? Hopefully not.

The guys at GPUgrid were looking to update their server next week (to support the 6.6.2 client). Hopefully they will wait a while.
