When corrupted results get validated...

Claggy:
I had a look for hosts matched with my E8500 / 9800GTX+ / HD5700 that were producing inconclusive/Invalid work:

GeneralFrost hostid=5356245 NVIDIA GeForce GTX 470 (1248MB) driver: 19775

Arles hostid=5355863 NVIDIA GeForce GTX 480 (1503MB) driver: 25715

Balmer hostid=5384948 [2] NVIDIA GeForce GTX 480 (1503MB) driver: 19775

djwhu hostid=5424576 NVIDIA GeForce GTX 480 (1503MB) driver: 19775

Tim Lee hostid=5301365 [2] NVIDIA GeForce 9800 GTX/9800 GTX+ (1024MB) driver: 19621

and there were a few more non Fermi hosts,

Claggy  >:(

Edit: another five Fermi's:

Bittkau hostid=5336843 NVIDIA GeForce GTX 480 (1503MB) driver: 19741

William hostid=5414447 NVIDIA GeForce GTX 470 (1248MB) driver: 19775

Anonymous hostid=5419662 NVIDIA GeForce GTX 470 (1248MB) driver: 19745

basti84 hostid=5391741 NVIDIA GeForce GTX 470 (1248MB) driver: 25715

edit 2: added more Fermi:

Aaron Danbury hostid=5373696 NVIDIA GeForce GTX 480 (1503MB) driver: 25715

Anonymous hostid=5025277 NVIDIA GeForce GTX 480 (1503MB) driver: 19741

Edit 3: added more Fermi:

My9t5Talon hostid=5419671 NVIDIA GeForce GTX 470 (1248MB) driver: 19775

simi_id hostid=5419256 NVIDIA GeForce GTX 480 (1503MB) driver: 19741

I think we should send David A. around to tell them off!  :o

Raistmer:
And most important thing I see in this list - they not only FERMI GPUS!
But there can be 2 independent problems still:
1) corrupted GPU state of pre-FERMI GPU that produces random pulses and programmatic error in early CUDA app that produces non-random, but invalid pulses on FERMI GPUs.
Second one will always pass into database if 2 FERMI with broken apps meet together.
But first most probably should not pass Validator (our database Guardian in some sense became Blind Guardian ;D ;D ;D )
Problem with broken app for FERMI is resolvable. But will 1) let invalid results go into database too or not - it's hard question that needs some more evidencies IMO. If yes....  ::)

Richard Haselgrove:
Of the Fermi cards (the first 8 in Claggy's list), seven are running the stock v6.09_cuda23 application.

Just one - smithwr3 - is using an app_info, and he's got one of Raistmer's v12 builds. I don't know enough about the std_err to be able to tell whether it's the special one he did for Fermi, and since smithwr3 hasn't posted in the forums since he was struggling with a Mac almost 4 years ago, there's not much to go on.

Very low probability he could take that version. And even so, IMO Jason showed already that initial CUDA MB code has programmatic error that "silent" on pre-FERMI GPUs but leads to invalid computations on FERMI . I used same codebase, just rebuilt app with new SDK. That is, V12 in no way FERMI compatible.
