Default Triple check required

Not sure where this is supposed to go.

One of my machines finished a DC a few days ago, and it didn't match the first one. This machine has delivered many correct/verfied results before, so I do not question its reliability (although anything is possible)

Here is the exponent:

35991733

Can someone check this? If the result is the same as the original test, then I will take a look at the machine in question.

I'm pretty sure your result is correct.

Your CPU that ran this one has 57 good, zero bad, 2 unknown (which consist of the one mismatch and one that's only been checked once).

The other machine, on the other hand, has 4 good, 7 bad, and 6 uknowns which consist of a 3 that were only checked once and another 3 that have been double-checked already without a match.

In fact, in a case like this, my analysis of good/bad systems would count your result as correct and the other as bad, based on the track records of each. So don't worry about it.

I'll run a triple check, but Madpoo's post makes me think you have nothing to worry about.

Exclamation

So I got my second double-check mismatch since joining at the start of the year:

http://www.mersenne.org/report_expon...0374797&full=1 (240,374,797 - 1)

Anyone feel up for triple-checking that one? Note that it is a machine that I only just added to my farm, so its reliability is unproven (even though an LL test that was running at the same time on the other CPU core successfully verified the previous residue).

Hmm... yeah, that's an unknown for sure. Both CPU's that did a test have 1 good and zero bad. That older one does have 1 suspect result in it's history which also didn't match, so the odds are stacked against that one being correct but it's not a clear call either way.

Anyway, it's already been assigned out so hopefully it'll actually get done, but I think I like your result more than the other.

I recently finished 35073793 DC with a mismatch. This was on a GPU. Last I looked it was still unassigned.
