Welcome to the 50th Anniversary of the Moon Landing Challenge
The fourth Challenge of the 2019 Challenge series is a 5 day challenge to celebrate the 50th Anniversary of the first humans landing on the Moon as part of NASA's Apollo 11 lunar mission. The challenge is being offered on the Proth Prime Search (LLR) application.
On 20 July 1969 an estimated 600 million people, a sixth of the earths population at the time, watched on television as the first humans walked on the Moon. During the Apollo program of the 1960s and '70s, NASA sent nine missions to the Moon. Six of them landed astronauts safely on the surface, the only times humans have visited another world.
Apollo 11 was launched by a Saturn V rocket from Kennedy Space Center on Merritt Island, Florida, on July 16 at 13:32 UTC, and was the fifth crewed mission of NASA's Apollo program. After being sent to the Moon by the Saturn V's third stage, the astronauts separated the spacecraft from it and traveled for three days until they entered lunar orbit. Armstrong and Aldrin then moved into Eagle and landed in the Sea of Tranquillity. Commander Neil Armstrong and lunar module pilot Buzz Aldrin landed the Apollo Lunar Module Eagle on July 20, 1969, at 20:17 UTC. Armstrong became the first person to step onto the lunar surface six hours later on July 21 at 02:56:15 UTC; Aldrin joined him 19 minutes later. They spent about two and a quarter hours together outside the spacecraft, and collected 47.5 pounds (21.5 kg) of lunar material to bring back to Earth. Command module pilot Michael Collins flew the command module Columbia alone in lunar orbit while they were on the Moon's surface. Armstrong and Aldrin spent 21.5 hours on the lunar surface before rejoining Columbia in lunar orbit. They jettisoned Eagle before they performed the maneuvers that propelled the ship out of the last of its 30 lunar orbits on a trajectory back to Earth. They returned to Earth and splashed down in the Pacific Ocean on July 24 after more than eight days in space.
To celebrate the 50th anniversary United States Mint has released the Apollo 11 Fiftieth Anniversary commemorative coins (I actually have one of these) and a documentary film, Apollo 11, with restored footage of the 1969 event, premiered on IMAX in March 2019.
To participate in the Challenge, please select only the Proth Prime Search LLR (PPS) project in your PrimeGrid preferences section. The challenge will begin 15th July 2019 20:17 UTC and end at 20th July 2019 20:17 UTC. Note that PPSE, PPS Mega and PPS-Sieve do not count towards this challenge.
Application builds are available for Linux 32 and 64 bit, Windows 32 and 64 bit and MacIntel. Intel CPUs with FMA3 capabilities (Haswell, Broadwell, Skylake, Kaby Lake, Coffee Lake) will have a very large advantage, and Intel CPUs with AVX-512 (certain recent Intel Skylake-X and Xeon CPUs) will be the fastest.
ATTENTION: The primality program LLR is CPU intensive; so, it is vital to have a stable system with good cooling. It does not tolerate "even the slightest of errors." Please see this post for more details on how you can "stress test" your computer. Tasks on one CPU core will take 1 hour on a fast/newer computers and 4 hours on slower/older computers. If your computer is highly overclocked, please consider "stress testing" it. Sieving is an excellent alternative for computers that are not able to LLR. :)
Highly overclocked Haswell, Broadwell, Skylake, Kaby Lake or Coffee Lake (i.e., Intel Core i7, i5, and i3 -4xxx or better) computers running the application will see fastest times. Note that PPS is running the latest AVX-512 version of LLR which takes full advantage of the features of these newer CPUs. It's faster than the previous LLR app and draws more power and produces more heat. If you have certain recent Intel Skylake-X and Xeon CPUs, especially if it's overclocked or has overclocked memory, and haven't run the new AVX-512 LLR before, we strongly suggest running it before the challenge while you are monitoring the temperatures.
Please, please, please make sure your machines are up to the task.
Time zone converter:
The World Clock - Time Zone Converter
NOTE: The countdown clock on the front page uses the host computer time. Therefore, if your computer time is off, so will the countdown clock. For precise timing, use the UTC Time in the data section at the very top, above the countdown clock.
Scoring Information
Scores will be kept for individuals and teams. Only tasks issued AFTER 15th July 2019 20:17 UTC and received BEFORE 20th July 2019 20:17 UTC will be considered for credit. We will be using the same scoring method as we currently use for BOINC credits. A quorum of 2 is NOT needed to award Challenge score - i.e. no double checker. Therefore, each returned result will earn a Challenge score. Please note that if the result is eventually declared invalid, the score will be removed.
At the Conclusion of the Challenge
We kindly ask users "moving on" to ABORT their tasks instead of DETACHING, RESETTING, or PAUSING.
ABORTING tasks allows them to be recycled immediately; thus a much faster "clean up" to the end of an LLR Challenge. DETACHING, RESETTING, and PAUSING tasks causes them to remain in limbo until they EXPIRE. Therefore, we must wait until tasks expire to send them out to be completed.
Please consider either completing what's in the queue or ABORTING them. Thank you. :)
About the Proth Prime Search
The Proth Prime Search is done in collaboration with the Proth Search project. This search looks for primes in the form k*2^n+1. With the condition 2^n > k, these are often called Proth primes. This project also has the added bonus of possibly finding factors of "classical" Fermat numbers or Generalized Fermat numbers. As this requires PrimeFormGW (PFGW) (a primality-testing program), once PrimeGrid finds a prime, it is then tested on PrimeGrid's servers for divisibility.
Proth Search only searches for k<1200. PrimeGrid created an extension to that which includes all candidates 1200<k<10000 for n<5M. It is this extension which we call PPSE.
Initially, PrimeGrid's PPS project's goal was to double check all previous work up to n=500K for odd k<1200 and to fill in any gaps that were missed. We have accomplished that now and have increased it to n=3M. PG's LLRNet searched up to n=200,000 and found several missed primes in previously searched ranges. Although primes that small did not make it into the Top 5000 Primes database, the work was still important as it may have led to new factors for "classical" Fermat numbers or Generalized Fermat numbers. While there are many GFN factors, currently there are only 297 "classical" Fermat number factors known. Current primes found in PPS definitely make it into the Top 5000 Primes database.
For more information about "Proth" primes, please visit these links:
About Proth Search
The Proth Search project was established in 1998 by Ray Ballinger and Wilfrid Keller to coordinate a distributed effort to find Proth primes (primes of the form k*2^n+1) for k < 300. Ray was interested in finding primes while Wilfrid was interested in finding divisors of Fermat number. Since that time it has expanded to include k < 1200. Mark Rodenkirch (aka rogue) has been helping Ray keep the website up to date for the past few years.
Early in 2008, PrimeGrid and Proth Search teamed up to provide a software managed distributed effort to the search. Although it might appear that PrimeGrid is duplicating some of the Proth Search effort by re-doing some ranges, few ranges on Proth Search were ever double-checked. This has resulted in PrimeGrid finding primes that were missed by previous searchers. By the end of 2008, all new primes found by PrimeGrid were eligible for inclusion in Chris Caldwell's Prime Pages Top 5000. Sometime in 2009, over 90% of the tests handed out by PrimeGrid were numbers that had never been tested.
PrimeGrid intends to continue the search indefinitely for Proth primes.
What is LLR?
The Lucas-Lehmer-Riesel (LLR) test is a primality test for numbers of the form N = k*2^n − 1, with 2^n > k. Also, LLR is a program developed by Jean Penne that can run the LLR-tests. It includes the Proth test to perform +1 tests and PRP to test non base 2 numbers. See also:
(Edouard Lucas: 1842-1891, Derrick H. Lehmer: 1905-1991, Hans Riesel: 1929-2014).

Curious if it's time for AMDs latest Ryzen 3rd gen of Zen 2 to be included in the information or will there be more testing needed before conclusions are reached? |

In my short time playing with them, it looks like AMD put in a softer power throttle than Intel, so it isn't all or nothing and will keep itself under control. Usually on Intel, if you hit the thermal throttle it is a bit late... |

Good luck everyone, lets find some primes. Lots of them!
Last challenge I had a bunch of errors from one system. One wrong memory setting can really make a difference.
It returned two good results then went down hill from there. Think I fixed it.
Good luck! |

Two PPS primes were found in the first 3 hours.
90K tasks have been sent out. 15K have been returned. Also, 13K were aborted.
Fastest validated task so far was 356 seconds. Although not prime itself, that task belongs to the same person who found one of the two primes.

So we already find 5 PPS primes or will find them very quickly. I think about more challengable task. Humans likes number one(or first). Primegrid looking for first prime for 5 k's in Seventeen or Bust project, first GFN 21 and 22 and so on. First means unique.
So here is a "challenge":
1. Can we find at least 1(One) factor of Extended generalized fermat number?(medium)
2. Can we find at least 1(One) factor of Generalized fermat number?(hard)
3. Can we find at least 1(One) factor of Generalized fermat number?(almost impossible)
Good luck to all searchers!

1) is already done -- the second PPS prime is an xGFN factor.
For 3, you meant Fermat number, not Generalized Fermat number, right?

After day 1:
Challenge: 50th Anniversary of the Moon Landing
App: 10 (PPS-LLR)
(As of 2019-07-16 20:48:48 UTC)
295060 tasks have been sent out. [CPU/GPU/anonymous_platform: 291392 (99%) / 0 (0%) / 3668 (1%)]
Of those tasks that have been sent out:
27369 (9%) were aborted. [27369 (9%) / 0 (0%) / 0 (0%)]
126 (0%) came back with some kind of an error. [126 (0%) / 0 (0%) / 0 (0%)]
171149 (58%) have returned a successful result. [167540 (57%) / 0 (0%) / 3610 (1%)]
96421 (33%) are still in progress. [96365 (33%) / 0 (0%) / 58 (0%)]
Of the tasks that have been returned successfully:
56880 (33%) are pending validation. [55774 (33%) / 0 (0%) / 1107 (1%)]
114195 (67%) have been successfully validated. [111692 (65%) / 0 (0%) / 2503 (1%)]
52 (0%) were invalid. [52 (0%) / 0 (0%) / 0 (0%)]
22 (0%) are inconclusive. [22 (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=2759500. The leading edge was at n=2749370 at the beginning of the challenge. Since the challenge started, the leading edge has advanced 0.37% as much as it had prior to the challenge!
This is somewhat more than we had been expecting. We had to load more work!
Keep it up!!!

2. Can we find at least 1(One) factor of Generalized fermat number?(hard)
Do numbers that are themselves generalized Fermat primes count. Any number divides itself.
Last time this PPS project found such a beast appears to be in May 2017:
625*2^2483272 + 1 = (5*2^620818)^(2^2) + 1

Apollo 11 reached the Moon's surface 50 years ago with Neil Armstrong and his fellow astronauts Buzz Aldrin and Michael Collins on board. Here are some key quotes from the mission that put the first people on the Moon.
"I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth." President John F. Kennedy announces his intention to put a man on the Moon before a joint session of Congress on May 25 1961
"No nation which expects to be the leader of other nations can expect to stay behind in this race for space...We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard." John F. Kennedy explains his lunar ambitions in a speech at Rice University on September 12, 1962
"10, 9, ignition sequence start, 6, 5, 4, 3, 2, 1, zero. All engines running. Liftoff! We have a liftoff! Thirty-two minutes past the hour. Liftoff on Apollo 11!'" Jack King, Nasa Chief of Public Information, commentates on the launch of the Apollo 11 over a live television broadcast on July 16, 1969
"Houston, Tranquility Base here. The Eagle has landed." Neil Armstrong tells Nasa's Mission Control base in Texas that the Eagle landing module has reached the Moon's surface on July 20, 1969
"Roger, Twank...Tranquility, we copy you on the ground. You got a bunch of guys about to turn blue here. We're breathing again. Thanks a lot!" Capsule Commander Charles Duke expresses the relief of Mission Control after nerves were tested during an unexpectedly complicated descent to the Moon
"This is the LM pilot. I'd like to take this opportunity to ask every person listening in, whoever and wherever they may be, to pause for a moment and contemplate the events of the past few hours and to give thanks in his or her own way." Buzz Aldrin's broadcast, shortly after landing on the Moon and before he took a private communion on board the Eagle landing module
"That's one small step for man, a giant leap for mankind." Neil Armstrong fluffs his lines as he steps out of the Eagle landing craft and onto the Moon's surface, turning Nasa's carefully prepared landing script into the most famous tautology of all time
"The surface is fine and powdery. I can kick it up loosely with my toe. It does adhere in fine layers, like powdered charcoal, to the sole and sides of my boots." Neil Armstrong describes the surface of the Moon
"Magnificent desolation" Buzz Aldrin reflects on the view from the Moon after stepping off the Eagle landing module onto the lunar surface
"Hello Neil and Buzz. I'm talking to you by telephone from the Oval room at the White House, and this certainly has to be the most historic telephone call ever made. I just cannot tell you how proud we all are of what you have done. For every American, this has to be the proudest day of their lives." President Richard Nixon congratulates the astronauts on being the first men to walk on the Moon
"Fate has ordained that the men who went to the Moon to explore in peace will stay on the moon to rest in peace. These brave men, Neil Armstrong and Edwin [Buzz] Aldrin, know that there is no hope for their recovery. But they also know that there is hope for mankind in their sacrifice." The opening lines of a speech, prepared by President Nixon's speechwriter William Safire, to be used in the event of a disaster that would maroon the astronauts on the Moon.
"Here Men From The Planet Earth First Set Foot Upon the Moon, July 1969 A.D. We Came in Peace For All Mankind." The inscription on a plaque left behind on the surface of the Moon after the astronauts departed.
We would like to give special thanks to all those Americans who built the spacecraft; who did the construction, design, the tests, and put their hearts and all their abilities into those craft. To those people tonight, we give a special thank you, and to all the other people that are listening and watching tonight, God bless you. Good night from Apollo 11." Neil Armstrong concludes the final television broadcast from Apollo 11 on the night before splashdown, July 23, 1969
“This is the greatest week in the history of the world since Creation.” President Nixon enthuses upon greeting the Apollo 11 crew after they splash down in the Pacific Ocean on Jul 24 1969
"Hey, we missed the whole thing." Buzz Aldrin to Neil Armstrong after watching a video of the press coverage of the Moon landing while in quarantine after splashdown. |

Not sure what you are saying, but any prime found here in PPS that divides a GF(n,b) (not an xGF(n,a,b)) for b=3,5,6,10,12 (only these b) would enter the first list. And any prime dividing an F(n) (that is, b=2) would enter both lists.
Edit: An example: The prime 87*2^3279368 + 1 divides GF(3279367,7), but is not in Caldwell's Top Twenty because he disfavors 7 and 11.

The Task Status page shows PPS has just exceeded 200,000 completed tasks per day. That's incredible!

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%)]
758496 (83%) have returned a successful result. [744446 (82%) / 0 (0%) / 14054 (2%)]
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%)]
663830 (88%) have been successfully validated. [651586 (86%) / 0 (0%) / 12244 (2%)]
392 (0%) were invalid. [392 (0%) / 0 (0%) / 0 (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!

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.

Thanks for the answer.
Going to get harder to fined them but I just now got an email finding another Prime https://primes.utm.edu/primes/page.php?id=126664

I am not participating in as much as I have no intention of basing my subscriptions on what challenges are under way. (I would have very little chance of a payoff, so I try not to notice they are even happening.) However I noticed one machine is doing a lot of PPS. Am I being roped in as wing man for everyone else doing the challenge? |

I see "Completed and validated (1st)" on some of your PPS (LLR) v8.03 Tasks.
http://www.primegrid.com/results.php?hostid=944117&offset=0&show_names=0&state=4&appid
What do you mean by "payoff" Find a Prime?
You can also select to not run PPS (LLR) v8.03 Tasks on your Hosts.
We all run task and some are wingman and some are not. |
|
|
|
|
What do you mean by "payoff" Find a Prime?
yes
We all run task and some are wingman and some are not.
I was not actually complaining. I was just curious. Sorry if it came across as a complaint.
More generally I am wondering how random the queuing system is. Obviously I am sure there is lots of randomness in it, but how influenced is it by things like Challenges?
EDIT: another duplicate. |

I do not think so, I know we are running a Lot of Aborted by user Tasks today but that is all part running PG |

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.

I'm really enjoying the challenge .. and very ready for it to end. 99 yesterday, 101 today.
If Noobs of Kryta and Ars Technica weren't so darn close, I could maybe trim sails ...but Noooo! It's a death march. I hope my machines hold out.

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.

Ha ha, in the very first post of this thread I wondered if we could find just one prime each day during the challenge. That was silly.
Nice event. Two tasks per second.

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.

The challenge started before the heat wave, is worst now, but temps will be cooler tomorrow (based upon where I live). One could argue that the heat wave is caused by this challenge. :-) |

1082957 tasks have been sent out.
The last time we had a challenge that sent out more than a million tasks was in November of 2017, when the Pierre de Fermat challenge sent out a combined 1159921 GFN-15, GFN-16, and GFN-17-Low tasks.

With five hours remaining in the challenge, it's time to remind everyone...
At the Conclusion of the Challenge
When the challenge completes, we would prefer users "moving on" to finish those tasks they have downloaded, if not then please ABORT the WU's (and then UPDATE the PrimeGrid project) instead of DETACHING, RESETTING, or PAUSING.
ABORTING WU's allows them to be recycled immediately; thus a much faster "clean up" to the end of a Challenge. DETACHING, RESETTING, and PAUSING WU's causes them to remain in limbo until they EXPIRE. Therefore, we must wait until WU's expire to send them out to be completed. Thank you!

Summer is Summer and it is Hot in some areas and not so hot in other areas.
But Summer is also the Highest Cost for Electricity at least here in the USA. |

5%, and most of those were from the very beginning of the challenge.

Following up on the aborted tasks thing...
There's about 50K aborted tasks.
7 people have about 1K to 2K aborted tasks, 2 people have about 5K, and one person has about 20K. That person aborted 13K on the first day, and the rest on the second day.
Both of the people with 5K also aborted them all on the first two days.
Here's the breakdown, by date.
+------------+-------+
| d | cnt |
+------------+-------+
| 2019-07-15 | 25411 |
| 2019-07-16 | 21685 |
| 2019-07-17 | 1805 |
| 2019-07-18 | 1746 |
| 2019-07-19 | 912 |
| 2019-07-20 | 576 |
+------------+-------+
As you can see, 46K of the 50K tasks all happened in the first two days as people were figuring it out.
Why the interest in the number of aborted tasks? (The reason I put them in the statisics, by the way, is not because I actually care how many were aborted. They used to be lumped in with "errors", and they're not really errors, and it made it look like there were a lot more errors than there actually were.)

A lot of the errors are mine from one stubborn computer that does not like the memory at its rated speed. It is DDR4 3600 19.20.20.40 T2
AT 3600 it errors, but it can run good @3500, 3700, 3800 and 3900. @4000 windows freezes
It will even run 3500 16.17.17.38 T1
It has been running real good last couple days at 3700.18.19.19.40 T1 not one more error
Same system last challenge, gave me a bunch of errors. Different brand and speed ram.
But it too did not like the rated DR4 3000 it would run at 2800 2900 3200 and 3200.
So I changed brands and sped to the DDR4 3600. Does not like 3600
I have no idea why. All the other settings are all the same, DDR V and VVT and so on.
I saved the BIOS profile so not to make the mistake again with the wrong setting.
I will say the speed from 3100 to 3700+ makes a good bit of difference in task times when doing one task per core HT off, that's fore sure.
Sorry about all the errors
System is an EVGA z370FTW motherboard.
i7-8086k CPU - water loop cooling
G-skill DDR4 3600 19.20.20.40 old ram was vengeance DDR4 3000, both 2x8gb.
EVGA 1080Ti black GPU with water-block
EVGA 850w P2 PSU
Samsung 981 256gb NVME OS drive
PS,
Should mention that it did run at rated speed doing other projects like WCG
That even makes it more weird that it is the PG LLR tasks that made it do that |

1134613 tasks have been sent out. [CPU/GPU/anonymous_platform: 1116663 (98%) / 0 (0%) / 17950 (2%)]
Of those tasks that have been sent out:
58186 (5%) were aborted. [58186 (5%) / 0 (0%) / 0 (0%)]
1413 (0%) came back with some kind of an error. [1413 (0%) / 0 (0%) / 0 (0%)]
977780 (86%) have returned a successful result. [959880 (85%) / 0 (0%) / 17900 (2%)]
92884 (8%) are still in progress. [92856 (8%) / 0 (0%) / 23 (0%)]
Of the tasks that have been returned successfully:
78697 (8%) are pending validation. [77164 (8%) / 0 (0%) / 1533 (0%)]
898498 (92%) have been successfully validated. [882131 (90%) / 0 (0%) / 16367 (2%)]
502 (0%) were invalid. [502 (0%) / 0 (0%) / 0 (0%)]
83 (0%) are inconclusive. [83 (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=2790454. The leading edge was at n=2749370 at the beginning of the challenge. Since the challenge started, the leading edge has advanced 1.49% as much as it had prior to the challenge!
A total of 16 PPS primes were found during the challenge. Great job everyone!
Now it's time to enjoy the A/C for a couple of days. Cleanup information coming soon, but this will be a quick cleanup.

Did the challenge have any significant impact on the PPS sub-project "life" expectancy ?

I've already given you enough information to figure out the answer to that question.
Edit: If you need more of a hint:
977780 (86%) have returned a successful result. [959880 (85%) / 0 (0%) / 17900 (2%)]
The other important information was on Discord: we normally do about 16000 tasks per day.

Hmmm, so we did in 5 days 977,780 tasks which would've normally taken 2 months (61.1 days = 977780 / 16000).
So, we "gained" around 56 days of PPS crunching.

Summer is Summer and it is Hot in some areas and not so hot in other areas.
But Summer is also the Highest Cost for Electricity at least here in the USA.
I'm humorously implying that so many people are participating in this project that it is causing the heat wave.
FYI, I maintain many of the programs used here and elsewhere (PRPNet, pfgw, gcwsieve, srsieve, etc.). For this reason I spend time on many different projects. I tend to focus on projects that have fewer participants as my cores will make a bigger difference to them than to any project here at PrimeGrid. |

So 17900 + 23 = 17950? What happrned to the remaining 27 sent out to an anonymous platform?
P.S.: Not trying to be tedious or anything. I was just amazed that none have been aborted or gave an invalid or inconclusive result. I'm curious how that's possible, so i had a closer look at the numbers. |

1134613 tasks have been sent out. [CPU/GPU/anonymous_platform: 1116663 (98%) / 0 (0%) / 17950 (2%)]
Of those tasks that have been sent out:
58186 (5%) were aborted. [58186 (5%) / 0 (0%) / 0 (0%)]
1413 (0%) came back with some kind of an error. [1413 (0%) / 0 (0%) / 0 (0%)]
977780 (86%) have returned a successful result. [959880 (85%) / 0 (0%) / 17900 (2%)]
92884 (8%) are still in progress. [92856 (8%) / 0 (0%) / 23 (0%)]
So 17900 + 23 = 17950? What happrned to the remaining 27 sent out to an anonymous platform?
P.S.: Not trying to be tedious or anything. I was just amazed that none have been aborted or gave an invalid or inconclusive result. I'm curious how that's possible, so i had a closer look at the numbers.
There's a lot of possibilities NOT included in those statistics, such as tasks sent out during the challenge but returned after the challenge. Or tasks sent before the challenge and returned during the challenge. For the numbers to add up perfectly, I'd need to show a very large and confusing array of statistics.
I'm not the least bit surprised that there's no app_info (anonymous platform) tasks in the aborted or error categories. These tend to be highly technical users who often know exactly what they're doing. I wouldn't expect there to be a lot of errors.

Two PPS primes were found in the first 3 hours.
90K tasks have been sent out. 15K have been returned. Also, 13K were aborted.
Fastest validated task so far was 356 seconds. Although not prime itself, that task belongs to the same person who found one of the two primes.
OK
I:m not counted. Today we hat a big Win 10 update - but I think not the Problem.

229 T-Armstrong BOINC Confederation 97 648.17 582

229 T-Armstrong BOINC Confederation 97 648.17 582
And, as such, this is appears in the overall stats, currently in 400th place.
This year (2019), T-Armstrong participated in 2 challenges (Hans Ivar Riesel's 90th Birthday - 213th place - and 50th Anniversary of the Moon Landing - 229th place).
In both T-Armstrong was the 2nd best cruncher in his team).
