Hello!

Looking to current validation of my results, the situation for LHC@home is never seen before:
30 results - validated;
8 - validation inconclusive.
So, success rate is less than 4/5!

Regards!

I'm at 50%, and the validated ones were the smallest that lasted only a few seconds :(

Update:
34 - validated;
28 - no consensus.
Success rate is approaching to 1/2.
My prognosis - in the next few hours validator will stop at all.
Happy crunching! :-D

I think I noticed something important:
All my WU that got the status valid, are calculated on another PC with the same operating system as mine (winXP)
All my WU that got status inconclusive, are calculated on another PC with a different operating system than mine.

Is it important information?

I've only got 22 validated successfully with about 180 still waiting validation, most of these got the validated inconclusive, some are actually waiting. Bummer is that the machines are hitting max units per day, because so many of them fail.

@Nawiedzony - I've had failures and good ones all on the same machine.

The validation of sixtrack fails for reason not related to numerical comparison.

We are still debugging this. Sometimes the validator fails to open the sixtrack output files, while the files are in the upload directory.
My guess is that it runs out of memory, or it may be related to the virtual memory setup in which we run boinc.

We have prepared a new fresh machine to transfer the sixtrack operations.

In the mean time, I will trim the daily quota to 2/day and max wus to send to 1.
If our server simply cannot chaw all the results that come in, this will give it some relief and # valid results will increase.

Being the Linux minority is definitely not conducive here. If there were a way to pair Linux only to Linux...

Update.
My hosts started to produce Invalid results.
Situation looks like:
1. validator is marking as Invalid all 3rd results after situation "Validation inconclusive";
2. WU is closed with canonical result (_0 or _1) after that.
Please, fix it (if I am right).

Since most (if not all) of the recent batch of Invalids were due to the Validator itself, will we eventually get credit for the work done; or is it "water under the bridge"?
