All under 42M now double-checked. I kind of wanted to get it done prior to the upcoming announcement of the new prime and just to cap the year off.

Let's see... 2017 started with double-checks clearing out somewhere between 38-39 million and now we've completed all under 42 million. Pretty good.

We're very close to the milestones for proving the ordering of M(42643801) -- just 1,426 to go. And M(43112609) isn't too far behind with just 2,974 to go. I think we can get those done in the first couple months of the year?

I still hope we find a "hidden prime" somewhere between 43M and 57M because that'd be pretty cool and fun, but at the current double-checking rate, I don't think we'll get up to 57M for 2-3 years at best unless we get a lot more interest in the DC work. That's over 236 thousand exponents to go, but we'll get there eventually.

I look forward to the day when PRP becomes the default work type, so we can "finish" the LL DC.

The 5,000,000th prime exponent is not so far away: 86,028,121

I not sure if that warrants a new milestone countdown?

if M86028121 could be a mersenne prime, that would be a nice coincidence

'fraid not:

Less than 9,999 primes remain to be tested for the first time to complete the classic view of 79.3 million.

This was the situation 2 years and 2 weeks ago (Jan 11, 2016)

I've been watching the milestone countdown for proving the placement of M42643801 since it had grown frustratingly slow.

Of the 7 currently left, one stopped responding 11 days ago, and all of the other 6 had been checking in somewhat regularly but were simply not progressing from day to day. Very unusual since it was from different users.

I checked today and noticed that those 6 that had stalled had all, as of earlier today, reported at least a minor tick upwards in % done.

I don't know what causes Prime95 to keep running (keep checking in results daily) but not progressing. Something else running on there keeping it from getting any CPU time at all? Doubtful. A setting to keep it from doing any work if certain programs are running, which happened to be left running for weeks on end? Maybe. Some other unknown bug?

It was just weird that it affected different users in this countdown and then they all, on the same day, picked up again.

Perhaps the next version of Prime95 should only request category 3+ work if there are any settings that keep it from running full time? At least exclude it from cat 0 and 1.

Anyway, just pointing out some strange observations on the server side. There are some in the countdown to < 77M first times that are also being stubbornly slow, and I've seen this in the past. Not a new phenomenon.

That was my line of thought exactly. I did want to look Zen and not fret too much but, yes, I did notice that what was a healthy path a few weeks ago (around the New Year) had began to freeze.

It has happened many times before but now that we have 3 milestones at our grasp -and yet so far- it becomes a bit frustrating.

Mind you, the only ones I care for, of the pending, are the M(42643801) and M(77 232 917) :smile:

As to the ‘million milestones’ they seem to be too artificial. I guess 45, 50, 55… and 79.3, 80, 85, 90 million are the only ones I am looking forward to.
