You can also look at the list by user and by year, and see that both LaurV and George have missed a P-1 factor.
Hmmm...I've missed 4, one recently (10 months ago); interestingly I found it myself via TF a couple months later.

Could this suggest a bug in Prime95? or more likely a hardware failure?

Early versions of Prime95 had P-1 bugs so there's lots of P-1 efforts from circa 2000-2005 that missed lots of factors.

But aside from that, there are still a (small) number of P-1 failures still occurring. I would guess that they're more hardware-failure than software-related, but I don't know enough to comment any more than that.

Huge James!

There's nothing quite like the empirical...

Question What about p>2^32?

Please add support for TF "no factor" results 2^32<p<10^10. There are 251,772,290 prime exponents in that range, and I want to be able to see how much TF has been run on such exponents without known factors. I see no reason why you couldn't add support for that. Without it, there's no way of knowing the progress on such exponents (unless a factor is found). Also, where on the Internet are people supposed to post results (factor or no factor) for exponents >10^10 (beyond Mersenne.ca's range) that aren't Double Mersennes? For example, M(10^10+19) or M(1111111111111111111). There needs to be a centralized place to put those as well - even if it's not on Mersenne.ca - as it would provide people (not just me) with a place to put such factors, given that Factor5 isn't limited to exponents <10^10.

57 bits (mostly).
TF in 1G-4G range does not record details for trivial efforts (less than 1GHz-day), and currently no detailed TF efforts above 4G are recorded, mostly for disk space / database size reasons. The effort to get the work to the 57-bit level was done by a very small group of reliable volunteers working in very large ranges taking entire 1G ranges to a higher bitlevel. I'm not prepared (yet) to open the 4G-10G range to public random contribution of NF results (which cannot be verified). TF-F results are fine since they are immediately verifiable. But in general I strongly discourage work above the 4G range for now.

Anyone could easily generate hundreds of millions of trivial factors for Mersenne exponents >10G faster than you could find somewhere to put them. You need to put the cutoff somewhere. Mersenne.ca does have limited capability of storing "interesting" factors for exponents >10G, where "interesting" is currently defined as k>=1M. These factors are currently archived but not available for public browsing (not because they're secret, I just haven't gotten around to writing such mechanism to do so). They're available as an SQL export at the very bottom of the export page.

Because of a couple of discussion of M1277 kriesel asked if I could update the data I provided you in #660. Let me know if there's a more convenient format

It might also be good if you rerun the query from #594 to see if there are any new larger ecm bounds curves.

Using the new t70/t75 counts M1277 show at least 2.25 complete for t65 and at least 0.487 complete for t70

Super-cool James et al. Empirically, you're "on this". As in, you already have the dataset(s).

So the question then becomes...

Could you please put this in a public-facing report that "only human" can understand?

With pretty graphs too? On a dashboard?

If that is not too much of an ask... 9-)

That's good (other than my obsessive need to column-align all the data), but to make it work on the site I need to extend the old-method list of expected bounds and curves up to 80, can you help me with that please?
Code:
function ECMeffortExpected() {
	return array(
		20 => array(    11000,    100),
		25 => array(    50000,    280),
		30 => array(   250000,    640),
		35 => array(  1000000,   1580),
		40 => array(  3000000,   4700),
		45 => array( 11000000,   9700),
		50 => array( 44000000,  17100),
		55 => array(110000000,  46500),
		60 => array(260000000, 112000),
		65 => array(800000000, 360000),
	);
}
I roughed in some placeholder numbers for testing, please correct me as to what they should be:
Code:
		70 => array( 2400000000,  900000),
		75 => array( 7200000000, 2250000),
		80 => array(21600000000, 5625000),

Note there are updated curve counts on the GIMPS ECM page as of last week (yes I should have done this years ago). These come from GMP-ECM -- these guys know more about ECM than I ever will.

Code:
Using B1=2400000000, B2=240000000000, polynomial Dickson(12), sigma=0:5846338435282416409

Expected number of curves to find a factor of n digits:
35      40      45      50      55      60      65      70      75      80
22      67      226     845     3407    14988   69914   350860  1845420 1e+07

16      44      135     455     1660    6464    27094   120646  567615  2809445

If anyone knows how to get GMP-ECM to show proper curve counts for t25 and t30 please let me know.

I have updated the curve count for 35..65 from your ECM page. I didn't follow from what you posted how to extend my lookup table to 80 digits (both bounds and curve count).
