Welcome to the Prime Time Challenge
PrimeGrid’s Challenge series continues with the "Prime Time Challenge". It's high time we initiated the new server and what better way to do it than with a Challenge. The success of the last Challenge secures PrimeGrid's future for growth and once again allows all projects to be considered for the Challenge Series. Our thanks continue to go out to those who donated and to everyone who participated in the Challenge.
[Initiate: to induct into membership by or as if by special rites, Webster]
It's time to return to the thrill of finding primes...and for that, we turn to PrimeGrid's newest project, the Proth Prime Search. Currently, these tests are rather short so this will also give us a good opportunity to "stress" test and fine tune the new server. The Proth Prime Search is slowly working its way up to the "reportable" prime level in Chris Caldwell's The Largest Known Primes Database! To view the bottom primes in the list, click on the following: 4900th-5000th primes.
As you can see, an n level of ~344,000 (5 Nov 2008) is needed to enter the database. Currently, PPS LLR is around n=290,000. We are confident that n=334,000 can be reached either in the run up to the Challenge or in the Challenge itself. So please come join us as we initiate the new server and bring the Proth Prime Search to the "reportable" prime level.
A 48 hour 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 14 November 2008 18:00 UTC and end 16 November 2008 18:00 UTC. Application builds are available for Linux 32 bit and Windows 32 bit. 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.
NOTE: For the past several months, our primary focus has been on getting the PPS Sieve deep enough to start LLRing. While we have made great strides in this effort, we still need more help. Leading up to this Challenge, anyone with a 64 bit multiple core system is encouraged to join the Proth Prime Search sieving effort. Please see this post if you are interested as it requires us to enable the project in your PrimeGrid preferences.
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 ~2 minutes on fast/newer computers and 4+ minutes 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.

Scoring Information
Scores will be kept for individuals and teams. Only work units issued AFTER 14 November 2008 18:00 UTC and received BEFORE 16 November 2008 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 wingman. 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.
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 manually tested outside of BOINC for divisibility.
Our initial goal is be to double check all previous work up to n=500K for odd k<1200 and to fill in any gaps that were missed. PG LLRNet searched up to n=200,000 and found several missed primes in previously searched ranges. Although primes this small do not make it into the Top 5000 Primes database, the work is still important as it may lead to new factors for "classical" Fermat numbers or Generalized Fermat numbers. While there are many GFN factors, currently there are only about 270 "classical" Fermat number factors known.
Once the initial goal is reached, we'll turn our focus to smaller k values and higher n values. For example, k<32 complete to n=2M, k<64 complete to n=1M and so on. Primes found in these ranges will 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 will be eligible for inclusion in Chris Caldwell's Prime Pages Top 5000. Sometime in 2009, it is expected that over 90% of the tests handed out by PrimeGrids will be numbers that have never been tested.
PrimeGrid intends to continue the search for 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 Penné 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: born 1929).

Those are mainly quads running 24/7 with 4GB and x64 OS so put them on PPS Sieving where they are more needed and effective.
But yeah, I may strech them on LLR for a while...

While I don't exclusively run PG I use my quad to run PPS Sieve WUs as well. I'm fine doing either the sieve or the LLR during the challenge (but not both on the same machine) but I do wonder whether the admins have a preference. :)

We haven't been able to reproduce the problem mentioned in that thread. However, we'll keep investigating.
The Challenge is only for the Proth Prime Search (LLR) and not the sieve. Therefore, only PPS LLR WU's completed during the Challenge will earn Challenge points.
On the other hand, the priority is the sieve. However, I think the sieve can spare 48 hours for a little healthy competition! :)

As you can see, an n level of ~334,000 is needed to enter the database.
Just to say that entering the 334,000 n level does not mean the start of real discoveries. In fact we must wait for n~400,000 as almost all the numbers below that level was crunched by me and Steven Harvey in the original prothsearch project. You can see an old report here. Please guess the meaning of the colors, numbers and faces yourself.
You can see there a big hole in 340000<n<360000 with k>600 in which I hope PrimeGrid make its first proth discoveries. Still there are chances with k between 1000 and 1200 and of course the missed primes. |

Thank you for your post. It pointed me to a typo on my part. It should read as of 5 Nov 2008, "As you can see, an n level of ~344,000 is needed to enter the database."
While it is true that a lot of the work being completed by PrimeGrid is doublecheck work, there are still many ranges left unexplored in the 600<k<1200 range.
n<500 for k<600 has been previously searched by ProthSearch. Yet we have found "missed" primes so there is still hope. Also, for 600<k<1200, a quick glance at the ProthSearch site shows the majority of the upper limits searched are between n=260K and 334K. Therefore, there are increased chances of finding "new" primes once we reach those levels.
Regardless of k, any "new" prime found must first reach n~344,000 in order to be eligible to enter Chris Caldwell's The Largest Known Primes Database! All the new primes we are finding now are nice, but they are not large enough to enter into the database.
Best of Luck in the upcoming Challenge!

Let me congratulate to all the PPS participants for reaching to n=300,000!!!
May I ask how many missed primes have we found already? How many new xGF factors? |

John and I should discuss fairly soon about locking up another swath of ranges for PrimeGrid. I suspect that the Prime Time Challenge could push PrimeGrid up to n > 350,000 and possibly > 400,000 on PPS LLR. I want to make sure that the other ProthSearch searchers have plenty of warning before PrimeGrid gets to n = 500,000. If PrimeGrid reserves for n < 600,000 (or a higher n) now, most (if not all) ProthSearch searchers below that n will complete their ranges by the time PrimeGrid gets there. |

For n<260K and 4<k<1200 (odd only), 173 new primes were found. Of those, 19 primes were missed in the previous search.
14 from k<800 and n<200K
1 from k<800 and n>200K
2 from k>800 and n<200K
2 from k>800 and n>200K
The remaining 154 primes are new primes which came from previously unsearched areas. They all have k>800 and n>100K.
As to the GFN factors, there were 18 new divisibilities (3 "GF" factors and 15 "xGF" factors).
There is one additional prime that was discovered in the 321 Prime Search: 3*2^2291610+1. This adds an additional 4 "GF" factors and 11 "xGF" factors.
EDIT: 27 Nov 2008
260K<k<300K - 7 new primes and 1 "xGF" factor

My home machine is doing 24/7 PPS Sieve (since it's a dual-core with 64-bit and enough RAM). But I'll put the three BOINCing computer at work into LLRing!
How much RAM does the PPS LLR app need? Some of these have low physical RAM...

Speaking of big disks......I don't remember where he got it, but I had a friend that had 40 MB hard drive (not for a home computer, for some business) that would not fit in the bed of a short bed Ford Ranger.
I think (hope) I still have a platter out of it around here somewhere. It is bigger than a large dinner plate with around a 3"-4" hole in the center. I think my friend told me there were 8 of them in the drive so they each were 5 MB. They were larger than 33 1/3 LPs also.

As I write this, 34 hours to go to the Challenge!
I really love these Challenges because they bring a sense of community. I am not really into the whole competition angle (tho I am determined to get at least one point this time) but I think that we all do have a lot of fun with them. :)
I hope it goes smooth, like the last challenge and we can be spared the rancour from the one before. :(

The Prime Time Challenge nears!
Less than 24 hours remain until the Prime Time Challenge (14-16 November 2008). The initiation process is already warming up as users are attaching to the Proth Prime Search (LLR) in advance of the start. We are approaching the "reportable" level in Chris Caldwell's The Largest Known Primes Database! Come help us reach it and find a prime for yourself.
Looking at the bottom of the list (4900th-5000th primes), you can see an n level of ~344,000 (13 Nov 2008) is still needed to enter the database. Currently, PPS LLR is around n=323,000 but moving fast.
This Challenge is being offered on PrimeGrid’s Proth Prime Search (LLR) application only.
To participate in the Challenge, please select only the Proth Prime Search (LLR) project in your PrimeGrid preferences section. The challenge will begin 14 November 2008 18:00 UTC and end 16 November 2008 18:00 UTC. Application builds are available for Linux 32 bit and Windows 32 bit. 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.
WU's should take ~2-4 minutes on a fast machine and upwards of ~6-10 minutes on slower machines.
A quorum of 2 is NOT needed to award Challenge score - i.e. no wingman. Therefore, each returned result will earn a Challenge score. Please note that if the result is eventually declared invalid, the score will be removed. Please see first post in this thread for more scoring information.
ATTENTION!!! A friendly reminder to everyone to check their machines to make sure they are stable enough for LLRing. No sense in losing precious CPU time on machines that are not up to par.
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. 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 everyone, check your machines to make sure they are stable enough for LLRing. No sense in losing precious CPU time on machines that are not up to par. If your machines are returning valid results, then you have nothing to worry about.
Challenge Points and BOINC credit (cobblestones) will NOT be granted to invalid results.
Let's get to the "reportable" level and Good Luck in finding a prime! :)

The start draws near
Again we are in unchartered waters. The server is doing fine, but we have never experienced such a high volume of traffic. It will be interesting to see how the server handles it. Here's some additional information:
- The web pages may take a very long time to load or even time out. This just means that more resources are being devoted to sending out work. We appreciate your patience. Chat rooms are available here: Meebo and Mibbit
- On the sever status page, almost all non essential stats will be turned off. The Proth Prime Search (LLR) will remain up and be cached every 15 minutes.
- The server has been configured to "spread the wealth". Meaning...if you have your client set up for a large cache, it will not be filled completely in one request...or even 2 or 3 requests...but eventually it will be filled.
- How can you help create a better start? Lower your cache before the Challenge begins i.e. 1-2 hours worth. Once you see that your cache is full, then you can start upping it slowly to your desired level. This will allow the maximum clients to receive at least some WU's and start crunching. While the clients are crunching, the server can catch up with sending out work.
- Challenge stats can be found on the front page...top right. Top Participants | Top Teams
Best of Luck!

That seems backwards. I think it would be better to let clients cache a large amount. That way they contact the server less often. If they have to make two or three requests to fill the cache, the server will be two or three times more loaded.

The gas tank needs filling! It sure didn't take us very long to go through 1200+ WUs.
Also, both of my computers have been having problems contacting the server to upload. One is okay but the other I won't know until I get home tonight; that one was having hostname issues with the server.

The Prime Time Challenge has been canceled. While the server is fine, we are having issues that we are not yet able to resolve. We sincerely apologize for this. More information to come when we have it.

This was the rule as stated at the bottom of this thread---
""Only work units issued AFTER 14 November 2008 18:00 UTC and received BEFORE 16 November 2008 18:00 UTC will be considered for credit.""
WU's issued prior to this would not count in the challenge--
I agree with you that it would better to cache fully before the start--
The only way I could see to keep to the rule and not have a couple of hours of non challenge WU's underway at the start was to --not accept any new tasks (empty the cache)-- then at UTC 1800--allow tasks-- I got 40 WU's per computer--
I suspect distribution of WU's may be why the operation was cancelled

I still have WU's that didn't clear out from about 24 hours ago, so at least there's some Prothies being crunched -- as is probably the case with many of you.
And if you notice the main page, PP sieve work is still available.

Thats OK if you have 64x system-- looking a bit grim for us 32x's--I'll be out of work in a few hours--- I see there is 1 PSP Sieve WU left-- maybe they will sell it to the highest bidder

I had wondered, when I got home from work, why my computer was doing nothing more than chatting to itself. ;)
And I guess we pay a little attention to other projects for the moment.

Looks like we are back in business-- WU's for everyone--- While I expect the PG guru's are a bit battle weary --be nice to get an update |

We have not yet pinpointed the issue that caused yesterday's problems.
While the Challenge as been canceled (will be rescheduled) we will continue keeping stats for the current dates (14-16 November). The reason for this is that we want to continue to stress the server so we can see the impact on different server related issues. This will help us better prepare for the Prime Time Challenge (Reloaded). :)
For those who are interested, please continue to crunch Proth Prime Search LLR through 16 Nov 2008 18:00 UTC. The results will be unofficial but the process will help us greatly. Thanks for the consideration and again, we apologize for the cancellation.

John –
Commiserations for the challenge event—While I leave the tech stuff to you—Might the problem be viewed as logistical and caused by participants (including myself) reactions to the “terms of engagement” (rules) of the challenge--- (see my post to Nicolas a few posts down)
I will Explain—8hrs before the start I was crunching large WU’s, these would finish at various times before UTC 18 – At this time I reduced the cache (as recommended) to under 2hrs and switched preferences to short WU’s (PPS & PSP) – I received a large number of WU’s . These WU’s would all finish before UTC 18 but I saw that I was going to pass the start with 2hrs of non challenge WU’s on board--- What I did (and probably many others) was stop accepting tasks--- At UTC 18 – accept tasks – (a lot of hungry hosts)—Not the actual cause of the problem—
If you examine the messages to and from PG minutes after the start--- We get 20WU per CPU (some 43min for me)—However with the cache set to 1 or 2hrs the BOINC Manager is continuously attacking the server looking for more work (every 1min or so) each request is answered by the server (20WU / CPU limit)—The work cache setting to avoid this should have been 30min--- If you look at the number of participants that would have been continually requesting additional but unnecessary work and the server responses its not hard to see why things went bad very fast.
I agree with Nicolas—Why not fill your work cache before the start & state the rule as “Only WU’s REPORTED AFTER UTC 18 start will count”
Is this technically feasible??—would this create a more normal server load???

Then it would be possible to stockpile a large amount of completed WUs and report them after the start, making the challenge unfair.
An idea(if this is possible):
For challenges, generate special WUs that can only be started at a certain time(the time at which the challenge begins.) Make it so these WUs have a higher priority than other applications, so when the challenge starts boinc pauses anything else in progress and starts to work on the challenge WUs only. This could allow people to stockpile WUs before the challenge starts and possibly prevent them from just aborting a large amount of other WUs/stopping computation to just wait until the challenge begins. This would reduce load during the challenge, everyone has WUs, and people start earning credit for the challenge as soon as the challenge begins.

SiK---
Point taken – I was not considering a dishonest prospective--- Your idea has merit.
However, as WU’s seem to upload automatically as soon as they are finished—might the upload time be a suitable trigger for challenge WU’s--- disregard manual reports.???

Well, you can still turn off network access for your BOINC manager if you have cached enough WUs. The ones that are finished will be "uploading" for days, until you allow network access again.
Would it be possible to put several LLR tests into one WU to make them run longer?

Ok— I’m an engineer – not a guru—but any solution has to be simple—easy to implement and controllable – and logistically feasible for the project scientists—
Lets turn the problem completely upside down--- Have intending participants register their computers--- give out WU’s according to 1, 2, 4 or 8 CPU.s (or whatever)--- Run the challenge on a number of different levels— Shortest time to complete Issued blocks of WU,s, Handicap honours where an old PC might get a win--- and of course most overall work done—
In other words –change the challenge from the number of WU’s crunched in a certain period-- to the time to complete a block of WU,s--- A challenge run in this manner could be run at any time with little disruption to the server – and consider the statistical data PG would get—accurate data on how long the particular WU takes on a variety of PC’s---
This changes the challenge from –WORK done in TIME to—TIME to do WORK—No doubt there would be issues to resolve ---- comments gentlemen????

The time on PPS LLR will increase ~35% in 1-2 weeks.

Possibly set the report date for all WU's that should not be part of the challenge to expire before the challenge starts. Only issue Challenge Worthy WU's 24 (or 12 or 6, whatever works) hours prior to the Challenge start time.
Yes, a few folks would still cheat by a day but, well, after a few challenges the cheaters would be obvious. And though they would continue to get away with it, well, that is between them and their ethics.

Hello
I was not in the list of my computers only included wu of the challenge this weekend, and those of my pps and PPR, the stats seem blocked? |

Is there a new date out there for the race?

Arn´t the primes find up to now not big enough for the top5000? My last numer has around 107k digits and place 5000 is around 103k.

Yes, the leading edge of the Proth Prime Search is in the "reportable" range in the top 5000 database. Unfortunately, many of these primes have already been reported. While we anticipated doing a lot of double checking, we did not expect so many ranges to be completed outside of the Proth Search effort.
Good news is that the higher the n, the less that has been searched. We are progressing at a fair pace right now and should see the first "new" primes trickling in anytime now.

Given we're getting close, please can you advise exactly which projects/programs should get credit when submitting to the top5000 list please?

Complete instructions will be emailed when new primes are found. For the Proth Prime Search, the following will be used:
"Jean Penne's LLR" as the proof method
"other persons, projects, or programs": PG, Srsieve, PrimeForm

I've noticed an increase of approx. 11% until now.
Is this caused by the increasing number of digits where we're searching now.
Is this also the reason of the increasing time of your mentioned 35%?

Seems so - the longer numbers must come at a cost.
Pentium M 2000 => 8' 16"
Core 2 Duo 2333 => 2' 44"
Gosh the Pentium M for sure is lame...
