Trippple Checks

[Madpoo]

Here's an updated list. Good job finding a bunch of factors!

I'm trying to understand the list.

Is the second number the bit level that it's currently factored to or what we should be double checking? And how high should we be making the bit level?

I might have a CPU core or two free in a couple days and GPU card in the same time frame to throw at this.

The list is just what the server would normally spit out for a double-check LL assignment. Any extra factoring beyond the bit level listed (which is how far it is *currently* factored) is up to whoever signs up to do any extra TF work on a block.

Be aware that there's a user "nesowa" who's doing their own TF work and he's in the 38-39M range right now I think, so exponents in that range from the list are probably going to get some work done.

Just pick a range from the list that hasn't already been spoken for... preferably something you could finish up in a few months or less, I guess (no hard and fast rules here).

Well, I'll take the 35M range (35M to 36M-1) to TF to 72 bits.

I handed in all work I signed up for now. I will be taking more, if and when it's getting neccecary again.

Awesome, thanks for that.

Here's an updated list that I think has all the latest stuff (requests for work, removed the stuff that's been factored or triple-checked) and I marked your TF work as completed.

I think petrw1's TF work on that first block is done... I believe he's doing double-checks on it now.

VictordeHolland had been doing TF work to higher bit levels. I don't know if he'd be interested in carrying it forward a few more bits than what you've done? Just tossing that idea out there.

And while I'm at it, I'm going to tackle doing the triple-checks on exponents between 20M and 21M.

Correct....60 DC to go....doing 2 or 3 per day

Rock on. :) I've been checking in a few in the 60M range and I got a 90M exponent checked in the other day. As soon as I clear the large ones (150-190M and the big 383M one) I can work on smaller ones too. I just liked the idea of clearing out the big boys first.

I've been clearing some of those v4/v5 self-verified ones since I have to do smaller exponents anyway on the other half of my 2-socket servers, to keep the memory usage from degrading everything. I think I've probably done a couple dozen of those in the 20-25M range so far.

I found myself wondering today, what would happen if one of these triple-checks did have a mismatch? When manually checking them in, if you see anything that suggests it didn't match the previously verified result, let me know.

Obviously step one would be to run a quadruple check and see what's happening and then we'd just need to look at that user to figure things out.

It's academic now... I don't really expect that to happen, but if I didn't think it was at least possible I wouldn't bother with this exercise. :)

Yes, I'll do that.
20M-22M is done to 71bits
I'll take <20M to 69bits and 22M-25M to 71bits

Speaking of triplechecks here: I just looked at very low Exponents, where the smallest not-triplechecked candidates are and found the first ones in the 1.36M area - Just for fun I tested a few of them and found this suspicious one:
http://www.mersenne.org/report_expon...1373881&full=1
There are two different residues both marked as "verified" and my result, that exactly matches one of the aforementioned ones but is flagged "bad" - does anybody know, what is going on there?
