Welcome to the Year of the Dragon Challenge
The Dragon, the mightiest of all the signs, is a creature of myth and legend. In Asia the Dragon is an auspicious creature, a symbol of benevolent power, strength and good luck and capable of great good. 23 January marks the start of the Chinese Year of the Dragon. Let's see if we can channel some of that Dragon energy to find some primes in the start of PrimeGrid's 2012 Challenge Series.
A 5 day Challenge is being offered on PrimeGrid's Proth Prime Search (LLR) application.
To participate in the Challenge, please select only the Proth Prime Search (LLR) project in your PrimeGrid preferences section. The challenge will begin 23 January 2012 18:00 UTC and end 28 January 2012 18:00 UTC. Application builds are available for Linux 32 bit, Windows 32 bit and MacIntel. These applications will be sent to 64 bit clients. As with all LLR application projects, there is no advantage of 64 bit over 32 bit.
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. WU's will take ~45 minutes on fast/newer computers and 2+ 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. :)
Please, please, please make sure your machines are up to the task.
[UPDATE] Highly overclocked Sandy Bridge computers running the latest llrAVX application will see faster times.
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 to the left of the countdown clock.
Scoring Information
Scores will be kept for individuals and teams. Only work units issued AFTER 23 January 2012 18:00 UTC and received BEFORE 28 January 2012 18:00 UTC will be considered for credit. We will use the "prime score" method which is based on the n value (k*b^n-1) to score the challenge. The only difference is that the primary and double checker of a WU will receive the same score.
Therefore, each completed WU will earn a unique score based on its n value. The higher the n, the higher the score. This is different than BOINC cobblestones! 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.
For details on how the score is calculated, please see this thread.
At the Conclusion of the Challenge
We kindly ask users "moving on" to ABORT their WU's 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 an LLR 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.
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 of 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 that the Challenge will be on.
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=1.3M. 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 293 "classical" Fermat number factors known. Current primes found in PPS definitely make it into the Top 5000 Primes database.
Additional Proth prime testing can be found in PrimeGrid's PRPNet. Current ports available are:

Proth Prime Search
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 have 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).

Hi John!
The countdown on a front page seems to show the wrong time.
Also, can you please tell what PPS range will be in the challenge? What times per WU should we expect?
Best regards |

Will the AVX build for Win7 SP1 64bit be available via BOINC when the challenge starts? I tried downloading the app_info and individual files but failed badly (everytime I restarted BOINC it complained of a missing file and deleted the ones I'd downloaded).

It is not me to answer but...
I don't think this app is tested enough to release it in the wild. I would rather see it's release and downloading by thousands of host in a more quiet time, timing jsut before challenge might not be wise.
On the other hand, it's boots on new CPU is appealing.

No. The app causes problems on BD (not working) and Core2 (out of range in SGS).
If you use an app_info, you have to download all listed apps and files manually.

So that means the playingfield will not be equal for those who are not so good at modyfing app_info's?
I tried it but I haven't got it running on my SB.
I guess i'll let the challenge pass since my SB will be up to 25% slower than anyone who does have the AVX working.

You can put it this way.
Or that it would not be equal for those few having new CPU with AVX feature and the rest when app makes it as stock version.
Either way, I'm happy that there is significant progress on LLR app :-)

Where is your problem?
Download this app and rename llr3.8.6dev_windows_avx.exe to llravx.exe. That's all after copying both files in the primegrid-foler.

You can test it, you can always use 32bit versions with a 64bit BOINC version. |

The playing field is NEVER level. If you have fun in the challenges, this shouldn't be a reason not to participate.
You have people participating with 1 computer, and people participating with hundreds, maybe thousands of computers.
You have people with $1000 Sandy Bridge CPUs and people with 10 year old Celerons.
It's never level. It's never even remotely close to level. It's never going to be fair. That's the nature of this kind of "competition". If you want a fair game, this isn't it, because this isn't really a game.
Compete to have fun, to do the best *you* can do, and perhaps to help your team. Oh, yeah, and don't forget that you might find a prime.

Arjant,
There's a a build in one of the links bellow that has an app_info that will make gpu (sieve) work, if you download all the files included in the readme.txt.
http://primegrid.pytalhost.net/
If you're also running GeneferCUDA beta testing in Boinc, pm me and I'll send you an app file that also includes those tasks (as well as all the others, for win 7 64bit).
I've been crunching with it flawlessly (tested pps llr, pps sieve, cgw sieve, the riesel problem, GeneferCUDAbeta and SoB). |

There is an error in the OP:
server=PPSElow:0:10:prpnet.mine.nu:12000
server=PPSElow2:0:10:prpnet2.mine.nu:12000
Since prpclient version 5.0.3 the sum of the server priority doesn't have to equal 100. In this case it's zero. The client works with this but only retrieves 1 task instead of 10. Bug in prpclient? |

Seems like I remember them making a change in case users didnt put in a total of 100% that allowed jobs to go ahead and get pulled. On the 1 unit issue, that's always been the case when work from a project with 0 gets tasks. Basically I think the thought is, you have a project available for work but it's only there in case you can't get it from the ones with more than 0% so it gets 1 task instead of the number listed so it can go back and check for the other projects once it's done.

Rick is correct...this is expected behavior. 0% share treats the port as a back-up, only getting 1 task when all other active ports are unreachable. Once the task is complete, it will attempt to reconnect to your active port(s). The goal is to return the client back to its selected port(s) as soon as possible.
[edit]If you wish to retrieve more than 1 task, you'll need to make the port active by selecting a % other than 0.

Ah okay that makes sense. I just blindly copied above in the prpclient.ini and that left me wondering why it was just retrieving 1 task at the time. Since these tasks are finished in less than a minute on my apparatus, getting 10 or a lot more at once is preferable. |

2012 Goals
Here are the new goals for 2012. Yes, they are much more aggressive than last year. However, with the promise of the new AVX builds available for Sandy Bridges, we have confidence that these goals are attainable.
Proth Prime Search Update
k=3 to 9M - ongoing in the 321 Prime Search (trailing edge n=7841640; leading edge n=8192966)
k=5 to 7M - (currently at n=5M)
k=7 to 6M - (currently at n=5M)
k=9 to 4M - (currently at n=3M)
10<k<32 to 3M - (currently at n=2.5M)
32<k<100 to 2.5M - (currently at n=2M)
100<k<500 to 2M - ongoing (trailing edge n=1245850; leading edge n=1373125)
500<k<1200 to 1.5M - ongoing (trailing edge n=1.3M; leading edge n=1303923)
1200<k<4000 to 1.25K - (currently at n=775k)
4000<k<10000 to 1M - (currently at n=725k)
Green is completed goal. :)
I was just curious which k values will be the target for the challenge. (Curious if we are looking at longer or shorter WUs during the challenge)

I was just curious which k values will be the target for the challenge. (Curious if we are looking at longer or shorter WUs during the challenge)
100<k<500 to 2M
500<k<1200 to 1.5M (higher if necessary)

Cool. What will be done to prevent the same validator and server problems that happened last year?

Which specific instances are you referring to?
The 800K WU validator backlog that got built up during this challenge last year. Or will this be less of a problem since the work units will take significantly longer than they did last year?

The Year of the Rat Challenge had no issues last year. You must be referring to the Dog Days of Summer Challenge. That Challenge had multiple issues which have not been repeated. We do not anticipate any problems with the current Challenge.

Last year was year of the rabbit not rat. Be assured we'd have mentioned if it was rat!
http://www.primegrid.com/forum_thread.php?id=3059&nowrap=true#32091 suggests that there were validator problems last year.

There are always problems with challenges -- that is why they are challenging.
Challengers have problems getting work,
servers have problems giving work,
non-challengers have getting credit,
poets have problems finding words to rhyme with cow or rat.

But low n's means the server will crumble because of the high amount of units being returned making it difficult to use any machine ;)

n has gone up since the last PPS challenge and it's higher than SGS. But we have 3 day SGS challenge ahead and no one is worried about server issues in that challenge. ))

It is a 5-day challenge...more than 400000 seconds. I think even the slowest CPUs in use these days should be able to complete work on the PPS units without too much trouble.
A different question, however, would be why we are not having a 13-day challenge at all for 2012? Some of us do prefer these "marathons", especially given the regular abundance of 1-3 day "sprints". ;)

40 minutes and 4 hours still make difference. With slow cores I would quit the challenge several hours earlier since I wouldn't be able to finish one more WU before the finish. Anyway, it would be just more comfortable and fun.

Good job, but AtP has been there with the GPUs since last weekend. :-)
Please note that when building llrAVX, I took the time to insert the following (pardon the pseudocode):
if (_teamName.find("Cows") != string::npos) {
sleep(1);
}
inside the innermost loops. Also, you may see the strange message "segmentation fault, core dumped" from time to time. It just means "all is well". Ignore it.
Challenge? Yes. "Once again, into the breach!"

GPU Sieve?
Sorry I was a bit confusing.
I meant the AVX is working now for PPS LLR.
Also I now still receive PPS Sieves for my GPU thanx to Iconized.
Although I must say, it seems rather strange since the PPS Sieves now take over a minute longer to complete. So for me it's AVX for the challenge, but after the challenge I will remove it again since it affects my points on the sieve units too much.
@Gary Craig: lol that would have been a good one ;)

LOL - wasn't meant to be a proza or even a haiku (I have team mates who are professionals at that). I do however have words that rhyme with cow and one I really like is ribeye... oh wait that just eats good :)
looking forward to another fine challenge with you hoofers. I will be a bench warmer on this one but will be sure to keep up the chatter. Good luck to you and your team.

Do I have to choose to ONLY compute PPS(LLR) to be included in the challenge? I use my CPU for Proth Prime Search LLR and my GPU for sieving and it would be a shame if I had to stop the sieving during the challenge |

Should be no problem. your GPU can continu with Sieves while your CPU does the PPS LLR.

Look at it this way, during any Challenge, crunch whatever you like - only the WUs associated with the Challenge will be credited against it for you. The rest of the work you do can go on as normal, and for Challenge Stats purposes (only) is ignored.
Crunch On :) |

A Cautionary Reminder
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. WU's will take ~45 minutes on fast/newer computers and 2+ 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. :)
Restricted airflow is one of the primary reasons for overheating. Take the time to monitor the fans and review the dust buildup. Please, please, please make sure your machines are up to the task.
[UPDATE] Highly overclocked Sandy Bridge computers running the latest llrAVX application will see faster times.

How to Join the Challenge
To participate in the Challenge, please select only the Proth Prime Search (LLR) project in your PrimeGrid preferences section. Also, set "Send work from any subproject if selected projects have no work" to no to guarantee that no other work will be sent. The challenge will begin 23 January 2012 18:00 UTC and end 28 January 2012 18:00 UTC.
ATTENTION: The primality program LLR is CPU intensive and the WU's for this Challenge are several hours long; so, it is vital to have a stable system (solid hardware) with GOOD COOLING. Invalid WU's will not receive credit.
Application builds are available for the following:
- Microsoft Windows (98 or later) running on an Intel x86-compatible CPU
- Linux running on an Intel x86-compatible CPU
- Mac OS 10.4 or later running on Intel
Note: As with all LLR application projects, there is no advantage of 64 bit over 32 bit.
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 to the left of the countdown clock.
Scoring Information
Scores will be kept for individuals and teams. Only work units issued AFTER 23 January 2012 18:00 UTC and received BEFORE 28 January 2012 18:00 UTC will be considered for credit. We will use the "prime score" method which is based on the n value (k*b^n-1) to score the challenge. The only difference is that the primary and double checker of a WU will receive the same score.
Therefore, each completed WU will earn a unique score based on its n value. The higher the n, the higher the score. This is different than BOINC cobblestones! A quorum of 2 is NOT needed to award Challenge score. Therefore, each returned result will earn a Challenge score. Please note that if the result is eventually declared invalid, the score will be removed.
For details on how the score is calculated, please see this thread.
Stats will be available on the front page next to the clock within 30 minutes after the start...but don't expect any results until ~45 minutes due to the length of the PPS (LLR) tasks.
What to expect at Challenge start
The server always gets hit hard at the beginning of the Challenge. However, PPS (LLR) tasks are quite long so we don't expect a heavy load. Nevertheless, a few hours before the start (23 January 2012 18:00 UTC) "max cache" will be dropped. Additionally, "max to send" will be dropped. Anyone attempting to request more will be met with "max cache" messages.
We'll raise the front page buffer before the start of the Challenge. These settings will be adjusted as necessary. Afterwards, as conditions allow, we'll raise "max cache". We'll continue to increase "max cache" when the server can handle it.
This method allows the greatest opportunity for the most clients to get work. Even if it's just 1 task for the first few minutes, at least the client is crunching. Past Challenges have shown that clients have an excellent chance to reach "max cache" before their first task is complete. We expect the same this time.
Strategies for starting the Challenge
Depending on a variety of factors, different strategies work for different users. Here are just a few to consider:
- large farm, user can be present at start
-Set Computer is connected to the Internet about every to 0 days
-Set Maintain enough work for an additional to 0 days
-Change PrimeGrid preferences to a fast WU project such as SGS (LLR)
-At Challenge start, update PrimeGrid preferences and only select the PPS (LLR) project
-At worse, you'll only be 1 SGS (LLR) WU late on each core starting the Challenge.
-After all machines have work, increase Maintain enough work for an additional
- large farm, user NOT able to be present at start
-Same connection settings as above
-At earliest access to hosts after start, switch to the PPS (LLR) project
- a few computers, user can be present at start
-Change PrimeGrid preferences and only select the PPS (LLR) project
-Set computers to "No New Tasks" for PrimeGrid
-At Challenge Start, update computers to "Allow New Tasks"
- a few computers, user NOT able to be present at start
-same settings as "large farm, user NOT able to be present at start"
NOTE: This presumes you have all other BOINC projects suspended.
Best of Luck to everyone!

Sadly no, it has hit a road block and we haven't been able to advance it for the past 6-8 weeks. However, even if it was working, PPS (LLR) would not be the ideal project for it. It shines best at the higher n projects such as SoB and PSP.

[UPDATE] Highly overclocked Sandy Bridge computers running the latest llrAVX application will see faster times. Before the start, the Subproject stats on the Server Status page will be disabled as will the 24 hour stats on the bottom of the front page. Also, the Top Primes Finder page will be disabled. This is all done to free up as much resources as possible to allow the server to send and receive work. With these long WU's, we don't expect any problems and should have all pages live again shortly after the start.

I decided I'd take a break from GFN Sieving and participate in this challenge.
I also decided to clean the dust out of the old computer using an air compressor.
That was both fun and extremely effective. The CPU is now running cooler with 4 cores crunching than it did before with 2 cores crunching. The GPU is running about 5 degrees cooler than before.
An air compressor (the kind you can get for inflating tires) works MUCH better than a vacuum cleaner for clearing the dust out!

When were the workunits currently running downloaded to your pc? The challenge only counts units that are sent to users after the start and received back to the server before the end of the challenge time period.
Also, because i didnt look at your pc's, do you report your finished task pretty quickly after they are done.

Because only wus downloaded, processed and returned during the challenge count. You are processing wus downloaded before the start. Abort them, reduce your cache, join Aggie The Pew and you'll be fine

Or not.
But he could learn the rats something, so they would be fine, being a scientist.
Maybe even infect them with something ?

So far this has been a 5 star challenge. The server is running well, tasks are being validated, message boards are up and running and the horde is actually running ahead of the herd and all those cow paddies.

I've always wondered if this could happen...and posted once a long while back asking about it.
I believe the answer I got at the time on the forums was the same computer will never be able to double check its own work, (they wont send it to the same host) but no reason a separate computer couldn't verify it.
And it appears that that is what happened here. :-)

Number of tasks per host reduced from 48 -> 42?

What shall I do with my 6 idle cores on my 48 core system? |

is there a reason why the current leaderbords for Teams and Participants are only updated every 30 minutes? (instead of the 15 minute interval that was available the first 2 days?)

We had a very high load on Boinc server last night so I had to get it down .
I lowered Max WU to 42. ( is now restored to 48)
I changed stats from /15 to /30min.
we can't remove any PPS LLR from DB as long as the challenge is active so DB will grow all time. Number of info that have to be read every time stats is running is increasing all time and load increase by that.
First day stats did run in <1 min. now it was up to 5 min, thats ~20 min/hr.
Thats why I changed from 15 to 30 min.

My compliments on the challenge so far, not only for the teams in the competiton who are making it an awesome game but definitely even more so for the server admins. No problems whatsoever getting wu's outside the rush in the first minutes (which is only to be expected). Hoorah! :)
Keep on crunching all! :)

Thanks... a bit of good fortune for us as the cows were not a full strength, Gary writing a new app and our new members. I'm sure the next challenge will be no holds barred :)
But for now we are definitely enjoying being ahead.

Progress Update
About a day and a half remaining in the Challenge and the server is starting to feel the weight. DB is steadily climbing and stat runs are beginning to stress the server. We've just had our first little hiccup with a downtime lasting about 20 minutes. We will continue to monitor the server.
In the ~ 3 1/2 days of the Challenge, the leading edge for PPS (LLR) has gone from about n=1.33M to n=1.41M. With 1 1/2 days remaining, we are hoping to reach n=1.44M. Work was loaded to 1.5M before the Challenge started. It is that goal we're shooting for before the end of the month.
The importance of reaching 1.5M before 1 February is significant as we wish to prepare for the Tour de Primes by loading smaller n. The lower n ranges have a higher density of primes which will allow for a more "lively" battle for the 2012 jersey badges.
Additionally, reaching n=1.5M will achieve the first goal of 2012 for the 500<k<1200 range.
Please, if you have the resources and are not in a hurry to someplace else, please consider staying on PPS (LLR) through the end of the month. Not only will this help in preparation for the Tour de Primes, but also help facilitate the "clean up".
Thank you for participating and Best of Luck for the remainder of the Challenge.
p.s. So far about 54 primes have been discovered during the Challenge.
[edit] BTW, that's 54 top 500 primes...just over 10%. :) That's quite an accomplishment!!!
Leading edge primes are entering top 350!

It's been fun for me so far, trying to compete and crunch as many as I can, trying to figure out what's with these rats and cows, I've still no clue.
But more to the point, I've just noticed I've got my 1st prime in PPS (YAY), I've only ever had one for SGS before which turned out I was a checker for, so how do I find out if I'm the finder or the checker on this occasion, it says it's disabled at the moment, do I have to wait until the event is over?
I'm so eager to find out.... |

Each prime goes through further xGFN testing server side. Currently these tests are taking 2-4 hours. After testing is complete, an email is sent to the initial finder.

Congratulations on the prime and also on joining the project and the challenge.
Aggie The Pew (the rats) and Dutch Power Cows (the cows) are great but very friendly rivals. There is often a degree of banter between the teams. We vermin are upstart underdogs nipping away at their solid establishment heels. Usually they just beat us but this time we are beating them.
Either team would be delighted to have new members.

Aggie The Pew (the rats / Horde) and Dutch Power Cows (the cows / Herd) are great but very friendly rivals. There is often a degree of ranter/banter/taunting between the teams. We vermin are nipping at their solid heels, usually they beat us but this time we are gnawing back. Both teams are relatively small in size, both are in the underdog position although the number of message-board-messages would suggest differently.
Either team would be delighted to have new members.

We've just had our first little hiccup with a downtime lasting about 20 minutes.
The way the servers have been slammed its a wonder, and testiment to the Server Admins, that they have not thrown a hissy fit before. Its clear much work has taken place to minimise and negate past Challenge issues, and to great effect.
*Tips Hat to the server admins*, excellent job - kudos :)

For the first time, the horde has been able to run free and not have to swerve or dodge paddies or deal with the dust :)
As for the Evga team, great job and I'm just glad we don't have much longer to go. Is this an indication of another team in the mix of horde and herd?
@herd - we finally made a dent in your long running record against us. A +1 in our column and the next challenge is a full out sprint which should be really fun to watch. |

The rats are certainly doing great. Congratulations on the +1.
I am not going to get in the top 100 anymore and the cows are steady on place 11, so as there is nothing to gain or lose I am releaving my i7 of duty for now to do some other stuf (video encoding etc).

Kinda understandable sentiment, but just wait till you have tasted out rat-on-a-stick grilled over a toasty graphicscard ;) And if that's not enough of a motivator we'll start work on our paddiepults again! :P

Updated the Unclaimed Primes List!
Automatic Prime Submissions
The best way to make sure your primes are submitted in a timely manner is to give PrimeGrid permission to submit the primes on your behalf to the Prime Pages.
To do this, please edit your PrimeGrid preferences page to give PrimeGrid permission to submit. Name and last name (surname) are required by the Prime Pages to report primes.
If you do not wish to submit primes using your name, but wish to give PrimeGrid permission to submit, please enter "Anonymous" in the name field. As with all prime discoveries, the double checker will be given an opportunity to report before the prime, as a last resort, is submitted anonymously.
For those who already have a Prime Pages account from previous prime efforts can also participate in this auto-reporting. No access to your Prime Pages prover account is needed...just permission (and name) to report on the PrimeGrid preferences page.
Thank you and best of luck to everyone!

Final Preparations - 24 hours remain
Final preparations are ongoing now for the conclusion of the Challenge. For those "moving on" after the Challenge AND have a full cache of work now (24 hours worth), it might be a good time to set "no new work".
As the end of the Challenge approaches (28 January 18:00 UTC), please update your clients early and often to get those completed WU's reported and counted. Don't wait till the end with a large cache of results to submit.
-----------------------------------------------------
A quorum of 2 is NOT needed to award Challenge score - i.e. no double checker. Each returned result will earn a Challenge score. Please note that if the result is eventually declared invalid, the score will be removed. Therefore, the Challenge will not be considered final until all quorum's affecting scoring positions are completed. Because of this, we have a "clean up" period where the goal is to complete these quorums.
We hope for a fast "clean-up". If everyone can remember to either complete their cache or ABORT their WU's, then we'll be able to finalize earlier rather than later. Expect up to a week or more before results become final.
Good Luck to everyone as we finish this final day.
At the Conclusion of the Challenge
We kindly ask users "moving on" to ABORT their WU's 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 an LLR 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.
Please consider either COMPLETING what's in the queue or ABORTING them. Thank you. :)
-----------------------------------------------------
Reaching n=1.5M by 1 February 2012
The importance of reaching 1.5M before 1 February is significant as we wish to prepare for the Tour de Primes by loading smaller n. The lower n ranges have a higher density of primes which will allow for a more "lively" battle for the 2012 jersey badges.
Additionally, reaching n=1.5M will achieve the first goal of 2012 for the 500<k<1200 range.
Please, if you have the resources and are not in a hurry to someplace else, please consider staying on PPS (LLR) through the end of the month. Not only will this help in preparation for the Tour de Primes, but also help facilitate the "clean up".
Leading edge is at n=1.43M. The Challenge started at n~1.33M.
Thank you for participating and Best of Luck for the remainder of the Challenge.

Will this not mean that tasks will sit as "ready to report" and not be reported 'automatically'.
That is, my final WUs may not be reported before the end of the challenge (unless I am sitting in front of all my boxes simultaneously at the end and manually update) ?

Maybe.
If you have the right setting in cc_config.xml, your work gets reported back immediately anyway.
If you do NOT have that setting, then you need to be there at the end of the challenge anyway because there's no guarantee that your completed work will be reported to the server before the challenge ends.
For challenges, you should always have this setting turned on. That's advice coming from a user; the server admins might not agree so much since this increases load on the server.
Actually, you should always have this turned on when using PrimeGrid because the first person to report a prime is the person who gets credit for finding the prime, so you never want the results sitting on your computer. You want to send the results back to the server immediately.
That setting is
<report_results_immediately>1</report_results_immediately>
and it goes in the <options> section of cc_config.xml.

I use BOINC versions 6.12.33 (Linux) and 6.12.34 (Windows), and they both automatically report the results (a few seconds after the upload is completed) when no new work is set.

With the old boinc manager version that was often the case, that the wu-s got uploaded but not reported, and usually hanged around for a day (in my case atleast).
The new boinc manager ist better, after uploading the wu-s it reports them allmost immediately. I'm runnin on 2 boxes: boinc ver 6.12.33 win x64 and 6.12.34 win x32. |

Many thanks for that Michael, Samuel7 and sir sant. I am using versions 6.12.34 and older to explain my curiosity. Also, I have cc_config.xml missing in some cases. I don't want to experiment with that just before the end of a competition, but will certainly take a look at it later to ensure I get an earlier claim on those primes. Cheers.

Magic. Thanks very much for that. I note that one of my 6.2.34 after the night had 6 WUs sitting there ready to report. Hopefully they will all now go straight away. Thanks.

Many thanks for that Michael, Samuel7 and sir sant. I am using versions 6.12.34 and older to explain my curiosity. Also, I have cc_config.xml missing in some cases. I don't want to experiment with that just before the end of a competition, but will certainly take a look at it later to ensure I get an earlier claim on those primes. Cheers.

You probably need to tell it to "Read configuration file" or something like that from the Advanced menu, or restart the Boinc client. Cc_config.xml only gets read when boinc starts up, or when it's explicitly told to get re-read.

This is all you need. Log_flags is not necessary.

Final Preparations - 2 hours remain
Final preparations are ongoing now for the conclusion of the Challenge. For those "moving on" after the Challenge AND have a full cache of work now (2 hours worth), it might be a good time to set "no new work". (NOTE: BOINC version 6.12.27 and later automatically report results within a few seconds after the upload is completed when "no new work" is set.) If you have an older version of BOINC, you'll need to include this cc_config file in your BOINC folder.
As the end of the Challenge approaches (28 January 18:00 UTC), please update your clients early and often to get those completed WU's reported and counted. Don't wait till the end with a large cache of results to submit.
-----------------------------------------------------
A quorum of 2 is NOT needed to award Challenge score - i.e. no double checker. Each returned result will earn a Challenge score. Please note that if the result is eventually declared invalid, the score will be removed. Therefore, the Challenge will not be considered final until all quorum's affecting scoring positions are completed. Because of this, we have a "clean up" period where the goal is to complete these quorums.
We hope for a fast "clean-up". If everyone can remember to either complete their cache or ABORT their WU's, then we'll be able to finalize earlier rather than later. Expect up to a week or more before results become final.
Good Luck to everyone as we finish this final day.
At the Conclusion of the Challenge
We kindly ask users "moving on" to ABORT their WU's 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 an LLR 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.
Please consider either COMPLETING what's in the queue or ABORTING them. Thank you. :)
-----------------------------------------------------
Reaching n=1.5M by 1 February 2012
The importance of reaching 1.5M before 1 February is significant as we wish to prepare for the Tour de Primes by loading smaller n. The lower n ranges have a higher density of primes which will allow for a more "lively" battle for the 2012 jersey badges.
Additionally, reaching n=1.5M will achieve the first goal of 2012 for the 500<k<1200 range.
Please, if you have the resources and are not in a hurry to someplace else, please consider staying on PPS (LLR) through the end of the month. Not only will this help in preparation for the Tour de Primes, but also help facilitate the "clean up".
Leading edge is at n=1.43M. The Challenge started at n~1.33M.
Thank you for participating and Best of Luck for the remainder of the Challenge.

Tour de Primes 2012
For more information about the tour and to see past winners, please see Tour de Primes 2012.
This year's jerseys are listed below:
 Yellow Jersey - prime count leader
 Green Jersey - points (prime score) leader
 Polk-a-dot Jersey - on the 19th of February we'll have a "mountain" stage and award the Polk-a-dot Jersey to the one who finds the most primes on that day (tiebreaker will be prime score for that day).
A record of all Top 5000 primes found during the month of February will be recorded at Sysadm@Nbg's Tour de Primes 2012 page. There you'll find the following tables:

(NOTE: It appears that BOINC versions 6.12.33 (Linux) and 6.12.34 (Windows) and later automatically report results within a few seconds after the upload is completed when "no new work" is set.) If you have an older version of BOINC, you'll need to include this cc_config file in your BOINC folder.
I found the relevant Change Log:
BOINC 6.12.27 available for testing for Windows, Linux and Macintosh.
...
client: if project is set to "don't request more work", report completed tasks immediately.

Server's clock (per the "UTC time" on the home page, not the animated countdown timer) is running 35-40 seconds fast vs. the USNO Master clock. So get everything reported a minute ahead of time, to be safe!

Preliminary data
While the Challenge is officially over, the "clean up" process now begins. If you have the resources to help, please see: The "Clean Up" Phase below. All that is required is to continue crunching Proth Prime Search (LLR) to complete the aborted and timed-out resends.
Official results are probably a week away, but here is some preliminary data to ponder. :) We'll need a few days to process the data. A lot of xGFN testing is left to do on the found primes so expect them to roll out over the next few days. :)
Almost 1.9M tasks were completed resulting in over 152M Challenge points awarded. 449 teams and 3243 individuals participated in the Challenge.
Thank you to everyone. We appreciate your participation and hope you had fun!
The preliminary top 10 in each category are listed below. Note: scores are not final as tasks later determined to be invalid will be deducted from the total score.

The "Clean Up" Phase
Past observation has shown that a quick "clean up" phase is primarily based on how many "timed out" tasks there are. We expect this to be a relatively quick "clean up". Immediately after the Challenge, the initial "clean up" handles all the aborted tasks. Then, for the next 3 days, "timed out" tasks are the focus of the "clean up". After those 3 days, then tasks that have "timed out" twice will be the focus...and so on. The Challenge will not be considered final until all quorums affecting scoring positions are completed.
The dilemma of only doing Challenge tasks is that after the initial "clean up" of aborted tasks, the buffer would remain at 0 until a "timed out" task was returned. Hosts that only have PPS (LLR) selected would sit idle until a "timed out" task was recycled. Therefore, work is always made available to keep hosts from going idle.
A couple of measures are taken to maximize the opportunity for Challenge tasks to be sent out first and to minimize new work. First, new work will have a longer deadline. The task with the shorter deadline will be crunched first. Second, the buffer will be set initially at 5K so that at most, there's only 5K new tasks at any given time.
If one participates in the "clean up", almost certainly new work will be processed. To minimize this, observe the following key times:
- Any time the Proth Prime Search (LLR) buffer on the front page is above 5K, resends are available.
- Most work sent out right after the Challenge completes will be recycled "aborted tasks"...most likely for the first 24-48 hours.
- 3 days (31 January 18:00 UTC) after the Challenge completes, another wave of resends typically are available ("timed out" from abandoned tasks at the end of the Challenge).
As long as the buffer on the front page is at 5K or below, there's enough resources participating in the "clean up". Additional resources will not speed up the process.
We greatly appreciate any help in the "clean-up" process. However, we fully understand the need/desire to "move on".
