1) Message boards : Number crunching : Half of the tasks get "Completed, validation inconclusive", what does that mean? (Message 60599)
Posted 15 Dec 2013 by [AF>FAH-Addict.net]toTOW
I don't know where I read it (probably on this forum), but the validation inconclusive status is part of how the project works :

- when you return your WU, the validator expect results to be withing a given range, based on the previous computation done on your run
- if you result is within the range, it will be validated immediately
- if it is outside the range, it will be marked as validation inconclusive and sent to another cruncher to validate the status
- if both results matches, they will be validated and run continues
- is results disagree, on more issue of the WU will be send to a third cruncher for validation

The process keeps going until enough results match to validate (and the WU gets validated), or until the maximum number of replications has been reached (this case leads to an invalid WU).

I really feel like project developers don't give a shit to their project !

Aren't you interested into getting less computation errors that would speed up the project and waste less resources ?

Also mikey, if you don't have a solution the issue described in the thread, please get out of it stop going of topic, that would be more useful !

To the other contributors reporting an issue, can you confirm the error codes you get are similar to those reported in the first post ?

I think I have given all the details I could to help someone who know to investigate on the issue. If you need more details, feel free to contact me.

I'm pretty sure that something is wrong with MW application, but it looks like no project developer is watching the forums ... that's a shame for such a big project :(

I'm pretty much sure that the issue is not from the overclocking or the card itself.

If my memories are right, error code 0xc0000005 on Windows means that a memory violation occurred ... but this is a Windows error, not something coming from the GPU.

mikey> yes, I forgot to take the last 0 in the URL tags ... but it's the only one I have on the project with DP capable GPU, so it's not hard to find it in my profile :D

I unchecked standard Milkyway@Home application in my profile to avoid the failing application, but I'd rather figure out what's goning wrong with my setup, it would be more useful to the project ...

Hi all,

I've restarted MW on my ATI which I didn't use for a very long time. It used to work fine, but now, I'm getting errors on every MilkyWay@Home v1.02 (opencl_amd_ati) tasks.

The WU seem to works fine (GPU usage 100%), but when they reach 100%, they error out.

The error seems to be always the same :

<core_client_version>7.0.64</core_client_version>

Engaging BOINC Windows Runtime Debugger...


These tasks are computed on this host, http://milkyway.cs.rpi.edu/milkyway/show_host_detail.php?hostid=250340 ...

Note that Milkyway@Home Separation (Modified Fit) v1.28 (opencl_amd_ati) tasks are doing fine on the same system. So as other BOINC apps.

Host is running on 7 64bits with Catalyst 13.4 (I noticed that 13.9 wouldn't update the OpenCL driver, so I didn't install it).

Any advice ?
