The first invalid result of my machine (The WU was calculated correct! I'm a beta tester and the app is running very well on my system.), because of two wingman with 'SETI@home v7 v7.03 (opencl_ati5_sah)' apps and wrong results. :-(
So this WU is uncrunched and lost?

26mr10ab.22208.11282.8.12.10 - wuid=1255961084

OK, OK, the result have 5x 0.
But the next WU have maybe 'better' findings?!

It would help if you will store tasks locally for offline investigation.

Message 1373857 - Posted: 30 May 2013, 22:15:55 UTC

Is there a problem with v7(opencl)? I am running Cuda42 and if my wingman is also running Cuda then the results are validated. But if my wingman is running opencl then the result is marked as inconclusive and if the 2nd wingman is also running opencl then result becomes invalid but if they are running cuda then the result is valid. Any suggestions?

Richards posts is about Boinc 6 that can't (and for now shouldn't) get ATI OpenCL MB v7 tasks at all. These SDK 2.5 clients runs Boinc 7, and they can get ATI OpenCL MB v7 tasks, but the problem is that they do get these tasks despite not having at least SDK 2.6 drivers.

it's a real problem cause false overflow occurs too fast.
Perhaps it's worth to stop plan class for older drivers at all if it can't distinguish SDK 2.5 drivers from SDK 2.6 ones.

Does this mean that apart from the waste of computer time, a lot of good results are being discarded as invalid whilst others that should be discarded are being marked as valid and therefore included in the database

Message 1373877 - Posted: 30 May 2013, 22:58:18 UTC - in response to Message 1373842.

Both wingmen are running too low an APP runtime version, need to be an APP SDK 2.6 driver/APP runtime :

Driver version: CAL 1.4.1607 (VM)
Version: OpenCL 1.1 AMD-APP-SDK-v2.5 (793.1)

Claggy

All my inconclusives are paired with hosts using the AMD-APP-SDK-v2.5... and they all ended in -9 overflow (except one with no data in the stderr)...
It seems something that needs to be addressed ASAP...

At the moment, that seems to be what happens yes. I do hope, for the sake of scientific accuracy, that those SDK 2.5 hosts are stopped ASAP from getting any new ATI MB v7 tasks.

Ah, okay.
I just looked into the STDERR report of his wingman:

" Driver version: CAL 1.4.1607 (VM)
" Version: OpenCL 1.1 AMD-APP-SDK-v2.5 (793.1)

AFAIK this typo in plan class eradicated already. So look for new work assigment to those hosts. They should not get new MB v7 tasks...

So far my Windows 680 host and Linux 7970 host have successfully completed the new version 7 tasks. The 680 host picked up the CUDA 5 application. I just built an app_info.xml file for my Linux host so that I can run both setiathome_7.04_x86_64-pc-linux-gnu__opencl_ati5_linux and ap_6.07r1844_sse2_clATI_linux64. GPU load is in the range of 91-93% on both cards.

This is a news thread......
If you would like help with your difficulty, please post your question in the Number Crunching thread.
Lots of folks there working on various questions with the v7 rollout.

Meow!

Again, for all here.
This is a news thread. Please post questions or problems in Number Crunching.

The kitties have their v7 caches full, so if you are properly set up, I think you should be getting enough work.

Get thee hence to the proper thread, and somebody shall try to help you figure out what is going wrong in your case.

It's well known that GTX560Ti's had probs with stock SAH Enhanced apps.

But also with the new SAHv7 (x41zc) apps?

Only errors: hostid=6598140.

What is here the problem?

What a nice message.

You read already the number crunching forum because of NVidia driver problems which cause computation errors (Kepler cards unsupported, the solution/workround)?
