Could people posting problems please be specific about which application processed the individual task or tasks they're commenting on?

Dave - we could look into that blank stderr_txt, if we knew. Or could you link the ResultID page? After all, you'll have had it open to read/copy that.

It just saves a lot of searching. Thanks.

I was also wondering why the 11.10 and 11.11 drivers were found to be incompatible with the app?

The apps aren´t incompatible the drivers produce wrong results.

We are checking that frequently.

I was also wondering why the 11.10 and 11.11 drivers were found to be incompatible with the app?

We are checking that frequently.

Well, it's the apps that compute the results. Saying they are incompatible is merely saying that the app and the driver don't get on well together - it doesn't say anything about which partner needs modifying to get them to work properly together.

As Mike says, we're still monitoring that and trying to find a solution. In the meantime, just be advised that the combination is unhappy.

Regarding -9 overflow results:

We very rarely see extended runs of -9 data on the tapes. You do see short clusters of -9 sometimes, but usually only on tasks which are closely grouped together, according to the other numbers in the task names. Check the numbers too: if a run of -9 continues into a different group of tasks, it's probably a problem - suspend processing and investigate.

First, check and see if your wingmates have reported the same tasks. If both computers report -9, and they validate together, things are probably OK.

Otherwise, some common -9 problems are:
on CPUs - overclocking or overheating. If you haven't changed anything recently, look for dust bunnies.
on NVIDIA GPUs - a computer reboot may cure it. If overclocked, back down a bit: GPUs can pass standard OC tests, but still fail to produce valid SETI results, especially under the added stress of the optimised CUDA apps.
on AMD/ATI GPUs - possible driver incompatibilities. If you downgrade from a newer to an older driver, run a driver cleaner to ensure all the newer components have been fully removed - installation programs, even ours, might be programmed not to overwrite newer files with older files. And the comments on rebooting and overclocking can apply to ATI cards too.

If the problems continue after you've checked all that, post here.

Richard,
Sorry, with going to bed last night and the site being down today...
Anyway, here's one:
blank stderr

Found a couple of blank stderr_txt, and just like dave, was previously on Lunatics .38. Updated to .39 and reverted to CAT 11.2 (previously on 11.11).

So, are blank stderr and -9 are something to look for and report?

skildude, I'm running two 6970 using 11.2 only problem I see is the occasional lock-ups when watching videos. I Might have to revert back to 11.11 since it only affects v7. At least that's how I understand it from Raistmer's post.

Hopefully, all the WUs I sent using 11.11 didn't produce false positives. Maybe someone can confirm?

Something doesn´t look right here.

Pixie got 2 69xx cards.
1 is reporting SDK 2.5 while the second reports SDK 2.3.
So i guess there are some driver left overs.
I´d suggest to completely remove the drivers using driver sweeper.
Make sure all AMD.ocl and/or ATI.ocl files are removed.
Reboot and install the drivers again.

Empty stderr.txt isn´t anything to worry about that happens sometimes but doesn´t affect the result itself.

Haven't done any actual testing, just been checking WUs with same deadline, is x41g somewhat slower than x38g? Seems to be maybe 2-3 mins slower on the longer WUs that I've seen, on VHARs maybe around 20 secs.

Thanks Richard and Mike.

I ran driver sweeper when I reverted :shrugs: I'll re-do the drivers soon as I get home. Thanks again.

It looks like both of their devices are reporting 2.5 and 2.3. Like they didn't uninstall the 2.3 SDK. Which is certainly interesting.

IIRC, x38g went out with slightly enhanced thread priority, which wasn't intended and caused slight lag for some users. We've gone back to the standard priority settings this time, which might make it run less aggressively on heavily-loaded systems.

In like-for-like bench testing, I don't think x41g was slower (I'd have to check), but YMMV.

The result I was looking at seems to both. http://setiathome.berkeley.edu/result.php?resultid=2181352660 With 2 devices under AMD Accelerated Parallel Processing v2.5 and then 2 under ATI Stream v2.3.

Was there another task where it one of each was shown? With both installed I only guess about what odd things may occur.

The first thing I did when I saw the WU's failing so quickly was to check against wingmen. Some were validated others were just left pending. Today I see that I have multiple invalids from those results.
I made sure I had everything off the system with the uninstall and with driver sweep. I did the same thing when I went back up to the 11.9 drivers. The only difference is that I didn't kill 100 or so WU's on the 11.9 drivers.

Trying to get OpenCL support, I got stuck with this problem, too.
Just deleted the 2.5 AMD-APP-SDK!
And whatever I do, no OpenCL support?!?!

I noticed 2 installers 32bit 0.38 and 64 bit 0.39(?)(0.41?)
I've cat.11.9 drivers installed, now.(I hope?)

The 4th result turned in and you are all marked as valid now. Crazy stuff.
