[QUOTE=Mr. P-1;275082]Otherwise, the most likely outcome is that the expiries will be re-taken up for LLing and never TFed further.[/QUOTE]

Bingo!

Mr. P-1, could I ask you to grab some exponents for me in the sub-50M range? I'd prefer to TF those than the 54Ms I have.

[QUOTE=davieddy;275108]Your "grab" is absolutely fine, in light of what you have done with it.
I just found it ironic that no sooner had Garo pointed out to Dubslow
the time and method of getting expiries, than you grabbed them all!
I hope he (Dubslow) got some.[/QUOTE]

Yes he did.

Garo did not, however point out the time and method of getting sub-50M expiries. I did that. Garo suggested up till 10 UTC for getting 50-51Ms

It is also feasible as long as you have 15 GPUs doing your option 1,
rather than 1 GPU doing your option 2.[/QUOTE]

If we have 15 GPUs each capable of doing 25 exponents from 68 to 72, then we could do that, and discover 25 new factors. Or we could TF 5,625 exponents from 68 to 69, and discover 88 new factors, assuming that 5,625 exponents TFed to 68 are available

The relevant questions are: How many GPUs do we have available for this work? How many exponents are they capable of processing in a day from 68 to 69? To 70? To 71? To 72? How many LL exponents expire each day? How many are assigned each day? Do we have enough GPU power available to bring one full day's worth of LL assignments up to 72 every day? If not, how high could we get one full day's worth of LL assignments up to every day?

One other question: Are we prepared to work together to make this happen? If so, then it would make sense for one person to do the daily grabbing, and farm out the exponents to everyone else.

[QUOTE=garo;275113]Bingo!

OK, I'll grab some for you tonight.

Working together is already happening with ckdo's crew, and it is now starting to happen with "Mr P-1's crew" or whatever we decide to call ourselves. I'd rather be discovering more factors -- there will always be more LL candidates passed out than we can keep up with.

Successive, higher bit levels come when we get a little ways ahead of the LL candidates -- that is, given the choice of hitting 1 exponent from 68 to 72 or 16 exponents from 68 to 69, if all 16 are about to get LL tested, it's better to do the 16 exponents, roughly quadrupling the chance of only needing 15 LL tests.

By the way, I have a present for Mr P-1:
1022665867263659549537 is a factor of M(50496583) by P-1, 2011-10-19 20:56

Please not that.

[QUOTE]I'd rather be discovering more factors -- there will always be more LL candidates passed out than we can keep up with.[/QUOTE]

I just gave you about 150 assignments, as you requested, in the expectation that you would be taking them to 72. Would it be better to give you batches of 2,250 (grabbed over several days of course) to take up to 69 only?

70 bits. I'm surprised it wasn't a GPU find.

Speaking of assignments, to get back on topic (relatively speaking) is there a way to reassign an exponent from one user to another without having to release it to the pool for a few seconds, even assuming that two people could get on at the same time.

Really? News to me.

Some Stats
 

I just reserved every LL expiry up to 50M to fulfil garo's request.

Total (up to 50M): 204

Of these:

35 were factored to 68 bits
163 were factored to 69 bits of which
->59 have not been P-1ed
->104 have been P-1ed
The rest were factored to 70 bits.

garo didn't say how many he wanted, but assuming these figures are representative of expiries generally, it looks as though a reasonable target might be to TF to 70 bits, all the 68-bits, and the non-P-1ed 69-bits. These I will PM to garo shortly. The rest I have unreserved in order to let the "average LL tester [] get a nicely TFed expo <50M".

The two people don't need to get on at the same time. The current owner can unreserve, log out, then manually re-reserve seconds later. I pretty certain that, with knowledge of the keys, "anonymous" assignments can be claimed.

Who is the right person to check with on the reservation system? P95? And do you have any scripts (Linux64) to assist with manipulating assignments? 20 or 30 assignments at a time is one thing, 150 at a time is another... While I'm at it, what happens if I put an assignment key on my "no factor found" lines on the manual results page?

I'm for beginning by ensuring everything in the assignment pool has 69 bits first, and then if we can keep up with that, we can chase 70 bits.

I'm now going to have my GPU do 2-3 days work on bringing your original list from 71 to 72 bits, with a moderate chance of finding a factor.
