1) Message boards : Number crunching : 50th Anniversary of the Moon Landing Challenge (Message 131295)
Posted 50 minutes ago by Profile Michael GoetzProject donor
It's been a long time since we've run a PPS challenge...

Last year's Solar Eclipse Challenge was at PPS-LLR. Back then, ~145k tasks per day were completed successfully and 9 primes were found in 3 days. So we're doing ~35% more (and slightly longer) tasks this time and might also end up with more primes per day.[/quote]

I stand corrected!

That's a significant increase over just a year ago.

We've already found 15 primes, with almost half a day to go, so we're at least tied with last year's 3 primes per day.

Post-DC, leading edge tasks have now started to be sent to users. The highest N that's been sent out is 31,627,174. The double check's highest N was 30,999,908.

There's still much double checking to be finished. There's still 284 "double check" tasks for which we have no result at all yet, and probably were beyond where SB's original check ended. Even though they're technically part of the double check, if they've never been tested, then they're just as likely to be prime as any of the leading edge tasks. It's kind of the best of both worlds: we could find a prime in the double check without it meaning that SB missed it the first time around.

With this challenge being as popular as it is, too bad it isn't running longer than 5 days.


There's a lot of sweating crunchers who are glad it's not any longer!!! Especially with what the weather forecast looks like for this weekend.

Also, this challenge is about as far as I want to push the server's database.

Is "13 primes have been found so far!" normal for this Event or do we see more most of the time?
"1 xGFN divisor!" I think this was me.
Now I know what that is...Divides xGF(2750266,7,4)
T5K, https://primes.utm.edu/primes/page.php?id=126656
701*2^2750267+1 is a Factor of xGF(2750266,7,4)!!!! (10616.880000 seconds)


It's been a long time since we've run a PPS challenge. What I can say is participation is very high, and we're crunching a whole lot of tasks. We had been doing about 16K tasks per day before the challenge, and now we're doing close to 200K per day.

After (almost) 4 days...

Challenge: 50th Anniversary of the Moon Landing
App: 10 (PPS-LLR)
(As of 2019-07-19 18:25:06 UTC)

909365 tasks have been sent out. [CPU/GPU/anonymous_platform: 895253 (98%) / 0 (0%) / 14112 (2%)]

Of those tasks that have been sent out:

30801 (3%) were aborted. [30801 (3%) / 0 (0%) / 0 (0%)]
730 (0%) came back with some kind of an error. [730 (0%) / 0 (0%) / 0 (0%)]

119346 (13%) are still in progress. [119287 (13%) / 0 (0%) / 58 (0%)]

Of the tasks that have been returned successfully:

94210 (12%) are pending validation. [92404 (12%) / 0 (0%) / 1810 (0%)]

64 (0%) are inconclusive. [64 (0%) / 0 (0%) / 0 (0%)]

The current leading edge (i.e., latest work unit for which work has actually been sent out to a host) is n=2782835. The leading edge was at n=2749370 at the beginning of the challenge. Since the challenge started, the leading edge has advanced 1.22% as much as it had prior to the challenge!


13 primes have been found so far!

Nice! Top Gun 2 trailer just dropped:
https://youtu.be/cVRHG6z7sN8


(no pun intended) I had goosebumps from watching that trailer. Thanks.

Yes. It looks like we will finish the challenge before 2020 ))


Hopefully. It depends on how much those last straggler cleanup tasks annoy Jim. If he's mellow enough, it might drag on into early 2020, but more likely he'll start manually running the really hopeless ones and that will speed things up a lot.

The GFN-WR Project is now called "Do you feel lucky".


Um... not exactly.

GFN-WR is now called GFN-22, although its internal, immutable name must remain genefer_wr.

DYFL (Do You Feel Lucky?) is an entirely new project. It fulfills the same purpose as GFN-WR used to fulfill, but it's a different project.

GFN-WR as a project name no longer exists.

And opening season III of this thread?


This thread is relatively new, and it's probably not going to get a lot more posts.
