When corrupted results get validated...

I have a horrible feeling that people who just throw a Fermi card into a host and attach, are being issued with the stock Cuda23 application and immediately start trashing WUs.
But we need robust reports from reliable witnesses....

Well, some of the reported workunits have a fermi card involved while others don't. The workunit from the first post here had 3-4 corrupted results, only one, if I remember correctly, was from a fermi with a cuda23 app. The other workunit I mentioned above had two 2xx cards involved with massive amounts of corrupted -9 results.

Suggestion: make copies of the WU and Task detail pages before BOINC purges them. Even better would be to find examples at SETI Beta where purging is disabled, and probably file deletion too. I started looking there, but no luck in finding any. Besides I got distracted by some of the nonsensical credit granting, one of Tetsuji's hosts recently did a set of reissued 0.448 tasks on 6.09 CUDA 23 with claims of 94.12 and grants ranging from 5.87 to 52.01 :o

Sorry, I didn't notice what my wingmen were running but I'm pretty sure the WUs were showing as 6.09s. I'm running a GT9500 on my vista X86 machine.
edit: Forgot to add I'm running the renamed cudart32_30_14 and cufft32_30_14 DLLs with the 197.45 driver.

Unfortunately, searching at Beta probably won't turn up many errors, because I've been leaning on David to get them fixed, and this particular problem (issuing work associated with a non-Fermi app, to a Fermi-equipped host) should no longer happen at Beta. There are just a few still visible on 12316.
All that's left is - why am I still trapped by yesterday's quota?
--- Code: ---Max tasks per day 153
Number of tasks today 273
--- End code ---
- and why is credit so erratic?

Credit granting on beta absolutely screwed. If you look on granting for AP tasks it will be even more obviously

And ontopic: cause first listed WU in this thread had no 2 Fermi GPUs, this problem not only Fermi-related (unfortunately). Looks like _any_ invalid overflow has some probability to be validated :(
