please take a look at this wu:

http://moowrap.net/workunit.php?wuid=26035

it's completed successfully by another system. Is there credit granted sometime or are wus like this staying "inconclusive" forever?

thanks for an answer

I was just going to start a new thread on this problem, glad to see I'm not alone. :)

On my slower GPUs (9800GT) the version 1.00 Wus returned the last couple of days are showing “validation inconclusive”, 1.01 WUs from the same machines appear to be validating alright. I aborted the remaining 1.00 work queued on those machines.

Are these results actually bad or was something changed on the Validator to cause the older 1.00 WUs to be marked as inconclusive?

yes, Teemu made a change in the validation (regarding this problem) for version 1.01.
If you guys see that same problem with 1.01, that's definitly a problem.

Sadly, Teemu will have to answer to this one.

I also noticed, i've few inconclusive too:

Also, what is inconclusive work really means?
Another bug with the validator?

Hi,

That validator change (basically it's more strict now) affects all workunits. But older application version is more susceptible for getting caught from having problems.

This means that the result was not fully done by the client and validator detected that. That's why there's a need to redo workunit with a new result. Once that other one is done and validated, the inconclusive result is supposed to get partial credit.

But it seems validator isn't granting partial credit correctly at the moment. I need to fix that but rest assured that partial credit for those results will be granted. :)

Hi,

Okay, partial crediting should be operational. Note that it can take up to a day from the time inconclusive result is detected to actually getting the credit. And longer if getting back a valid result is delayed.

Hi,

That result lost one packet and therefore didn't do the full work and got granted only partial credit. Dnet client sometimes looses work like this due to some bug in it. :(

518 fixes something regarding the OGR-27, which is not running on GPU, so it didnt affect us.
More infos at:
http://blogs.distributed.net/2011/04/11/15/12/mikereed/
But we're already running 518.

519 is in beta stage at the moment for GPU.

All 3 are inconclusive.


Aha! Those three indicate a bug in our validator. I'll take a look and hopefully will be able to fix this problem. Thanks for bringing these work units to my attention!

I also get some wus with the status "Completed, validation inconclusive" and later "Completed, marked as invalid".

I compared the stderr output of all wus I worked on and I figured out that the ones where I or the other user restored the workstatus from a checkpoint after a restart all became invalid", whereas the wus which run all at once were validated sucessfully.

I just finished a few wus, therefore it isn't representative but maybe this is one of the problems why results get invalid.

Some inconclusive work and eventual invalid (with partial credit granted) are normal. This happens if the work unit was not fully crunched but got some packets were lost due to some errors.

Looking at your three invalid results, all misplaced one packet so that's this normal situation. However, why they loose one packet is something that can be looked into and hopefully fixed. Checkpointing should preserve any packets while wrapper/client is been restarted. Any whole system hang (BSOD on windows) that results in loosing checkpoint files can have this effect.
