Welcome to the 'An Apple a Day' Challenge
Autumn (or fall, depending on which English you use) is drawing closer (if you live on the Northern hemispher) and that's exactly the time apples will be harvested. Conveniently consuming one of these a day will allegedly keep any doctors at bay. Unfortunately this is only a folk tale, as Apple Inc. co-founder discovered in 2011 on this day. So join us, either to celebrate the lovely fruit called apple or to commemorate the loss of Apple Inc.
A 1 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 5 October 2012 18:00 UTC and end 6 October 2012 18:00 UTC. Application builds are available for Linux and MacIntel 32 bit and Windows 32 and 64 bit. Hosts running 64 bit Linux or MacIntel CPU's will receive 32 bit . 64 bit hosts can have a small advantage over 32 bit hosts.
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 ~6 minutes on fast/newer computers and 30+ 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.
Highly overclocked Sandy Bridge computers running the latest llrAVX application will see faster times.
SPECIAL NOTE: As this challenges will be held on a subproject with very short units, the server will certainly feel the strain. If you have enabled instant reporting of completed results using cc_config.xml, please consider turning this off for the duration of the challenge. Minimizing the amount of times your client connects to the server will greatly help reduce the load!
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 5 October 2012 18:00 UTC and received BEFORE 6 October 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. These however do NOT count towards the challenge score! Current ports available are:

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).

I think it is more likely to celebrate what he, and Apple, did not his actual death. Apple brought a lot of changes to the marketplace and forced MicroSoft to make changes it might not otherwise have done. IMHO we the users ARE better off for Steve Jobs being who he was.
One thing I just did was change my settings so I could do some units now and I got the message that no units are available. Are they saving them up for the Challenge? |

I just did an update and got some units, it must have just been 'working on it'. |

The leading edge just passed 990K, what range will we use for the challenge since the current range will hit its goal for the year before the challenge? Will we push 1200<k<4000 to 1.25M since it is the next goal with units with short time?

I've talked to Lennart about this and this is his answer
We have to finish all up to 1M first so we might load 1M+ if we need more in the challenge and change to lower k's after the challenge. If we finish 1M before the challenge we might start on a lower k.

Pyrus we have a chain of stores here called Staples. They actually sell a magic button. It's called Easy and is rather inexpensive. You might even be able to order it online. If you can believe the tv commercials it will fix almost anything.

You don't say? I've heard of this Staples place but didn't know they sold magic buttons :) I might have to look in to that ;)

I got one for my boss when I was working, I am now retired, and he thought it was funny and you could here him pushing it whenever he solved a tough problem, or needed a laugh! In cubicles you can here everything and lots of people around him laughed when he pushed it, his job was NOT easy! Fortunately I fixed more problems than I created, BUT he did have to smooth out some problems I MADE!!! |

Hi _MaRiO[PL],
I totally agree with your sentiment and that's why I cobbled together a script to easily update the stats. You can see the results thereof here. I'll poke around a bit more to see about either getting a link to them in a prominent place or getting them hosted by pg.

I think the problem is that the second challenge did not award any points, so the PG table has no idea what to do.
I seem to remember others have asked for it to be fixed, but so far no luck.
PYRUS has a very good alternative.

As far as I know everything had to be updated manually. Including the post challenge stats. That was part of the reason I build my thingy :)

It may just be my imagination but is there some kind of issue with the server? Just wondering because I'm sure the upcoming challenge will almost surely break it based on how it's been acting lately.

Apart from the fact that the server time is five minutes or so ahead from what it should be, I didn't noticed anything strange with it.

TheDawgz have noticed a few things as well* -
Web page response times are fine and then drop off to down right sluggish.
WU downloads are fine then suddenly hang and then just as suddenly resume.
Does not appear to be time related.

I've noticed occasional random long times in loading pages and some 'server not responding' notices in Firefox. Once It does load a page I notice at the bottom of a page that the server load on 1-2 of the 3 numbers were at 4-5+ at that time, so the server is getting hit pretty hard at times now, even before the challenge.
I've also noticed more computers erroring out instantly on LLR tasks, especially ID230127 & ID175616 which shows up on more than 3/4 of all WUs I get. The constant downloading & uploading of errored WUs I'm sure puts more of an unnecessary strain on the server. Admin should PM & email these people and put a temporary ban until they respond that it has been corrected.
If all of this continues during the challenge we may have server problems similar to other short tasks challenges of past. Hopefully, though, all goes well.

I think I may have accidentally discovered what's wrong with the server. I'm not sure what, if anything can be done about it, however. I will let Rytis know about the details.
In short, there's a host with in excess of 23 thousand tasks. Database queries to view those tasks, under the right conditions, can run for long periods of time. This is, possibly, what's been causing the delays we've been seeing.

Addendum to my previous post: I think there's a simple fix. It may be as easy as adding one key to a database table. Maybe two keys. Keep your fingers crossed.

that's hardly unusual then. Wouldn't anyone running PPS be racking up that many tasks? |

I suspect the vast majority of those are errors that happen within a few seconds.
Normally, a computer wouldn't have that many tasks. Let's say, for argument's sake, that an i7 can do 8 PPS tasks every 10 minutes. Also, assume that a PPS work unit exists for 10 days before it gets purged from the database.
This i7 could do 48 tasks per hour, and 1152 tasks per day. Including a full 10 day cache of work units plus a 10 day bunch of tasks that already has completed but have not yet been purged, you're looking at 20 days worth of workunits, or 23 thousand tasks as the theoretical maximum.
That's assuming an i7 with hyperthreading on could do 8 tasks every 10 minutes, which is not likely with LLR. This is an older i7 and probably can't even do half of that.
The far more likely explanation is that it's erroring out in just a few seconds, creating thousands of errors in a short period of time. I haven't counted them, but it does have a lot of errors with only a few seconds of elapsed time.

Coincidentally I was doing some tests before the challenge. I didn't try 8 but thanks to avx, an i7 at 4.3GHz will do 7 of the current pps in 9:30.

Server clock time looks to be at least six minutes fast, per the "UTC time" entry on the front page, not the big "countdown clock" which I know is based on my box's time. Please correct before the start of the challenge to ensure a fair start. Muchas gracias.

I have attached several pc's for the challenge, my question is the prc's are running other projects right now with deadlines being long enough that I can suspend them with no issues. BUT if I suspend them tomorrow, the day before the challenge starts, will they get any work or is no work being sent out until the challenge starts? If the later than me, being in the US, must get up EARLY and switch my pc's over to give max effort towards the challenge. I would not mind crunching for pg in general and then at the start of the challenge have all units start counting towards it.
PS the Server clock is STILL about 6 minutes fast. |

There is always work available, though only the units that have been sent out after the challenge has started and returned before the challenge has finished will get challenge you credits. That means you can safely switch your pc's to PG at a time of your pleasing, though I would suggest keeping on only a (very) small buffer. You could even consider not running a buffer at all, which is what I'm going to do.

Thank you very much, a small cache is what I had intended. I will be making the changes tomorrow morning.
edit: I actually went thru and made all the changes just now, but only turned work retrieval on for one pc for now. |

really? I wouldn't have thought that would work too well on a small wu challenge. Shouldn't people should be encouraged to keep the maximum buffer (is it 80 WUs?) to stop the server getting hammered. |

You are right, during the challenge that's best for everyone. At the start though, especially if you can't be there to manually get it exactly right, no buffer is acceptable. The server will get hammered anyway those first few minutes ;)

Also, if you've ever watched how the BOINC client behaves (at least prior to 7.x.x), even with a large cache, as soon as it completes a WU, it decides it needs more work and asks the server for another WU. So, if your cache holds 1000 WUs, the initial 1000 may all be provided in a single request, but after that your computer will still ask for them one by one.
Probably not the best design. :)

that's hardly unusual then. Wouldn't anyone running PPS be racking up that many tasks?
I suspect the vast majority of those are errors that happen within a few seconds.
Normally, a computer wouldn't have that many tasks. Let's say, for argument's sake, that an i7 can do 8 PPS tasks every 10 minutes. Also, assume that a PPS work unit exists for 10 days before it gets purged from the database.
This i7 could do 48 tasks per hour, and 1152 tasks per day. Including a full 10 day cache of work units plus a 10 day bunch of tasks that already has completed but have not yet been purged, you're looking at 20 days worth of workunits, or 23 thousand tasks as the theoretical maximum.
That's assuming an i7 with hyperthreading on could do 8 tasks every 10 minutes, which is not likely with LLR. This is an older i7 and probably can't even do half of that.
The far more likely explanation is that it's erroring out in just a few seconds, creating thousands of errors in a short period of time. I haven't counted them, but it does have a lot of errors with only a few seconds of elapsed time.
The way some BOINC projects handle such high error rates on one client is to reduce the number of workunits that client can download in one day, until it starts returning a higher number of valid results. That tends to make more of the server time available to the better-performing clients.
They don't completely shut off workunits to those clients, because that would prevent detecting when it is working better. |

You could even consider not running a buffer at all, which is what I'm going to do.
really? I wouldn't have thought that would work too well on a small wu challenge. Shouldn't people should be encouraged to keep the maximum buffer (is it 80 WUs?) to stop the server getting hammered.
Also, id you've ever watched how the BOINC client behaves (at least prior to 7.x.x), even with a large cache, as soon as it completes a WU, it decides it needs more work and asks the server for another WU. So, if your cache holds 1000 WUs, the initial 1000 may all be provided in a single request, but after that your computer will still ask for them one by one.
Probably not the best design. :)
That may be why 7.x.x has changed that, so it normally asks for a group of workunits instead.
By the way, will the challenge offer only CPU workunits, or both CPU and GPU? |

There is no plan at this time to offer a GPU version of LLR in the foreseeable future. The performance just isn't enough to justify using a GPU. As far as I know, nobody is working on it at this time.

I don't know the answer to that question, but I can think of two possible reasons. One is nobody has actually decided that "This isn't going to happen." The other is that if anybody does decide to work on it, having the option there allows them to experiment in a full BOINC environment.
This tangent discussion is really off topic here, so if you have more questions, please ask them in the llrCUDA testing thread in the project staging area.
EDIT: This thread from about half a year ago is a good summation of where we stand with llrCUDA.

Hi todd,
You can join the challenge by selecting the Proth Prime Search (or PPS) LLR subproject from your preferences page. Make sure to only select the CPU variant, as the GPU variant will not work.

Also, you will want to make sure only the PPS LLR cpu is checked and no other sub project is checked so you don't get workunits from them. And one more note, only workunits sent to you after the start time and workunits received back to the server before the end time count in the challenge.
You may also notice rather "high" credits on the challenge stat page. Those are only for the challenge. Normal credits are still applied to the actual workunit/project.

Lennart says there's actually about a million in there, although the number you see is only those that are ready to be sent out. New tasks are generated automatically from the list you don't see.
And if we use up that million, Lennart is prepared with another file with an additional million he can load. :)

If you suspend a task from PG you will not be able to get any more workunits from PG. If you've got other subprojects running you can increase your cache while the other tasks aren't suspended and then suspend the other subprojects.

Hi, guys:
I threw 21 32-core boxes at this challenge, and am seeing a 16-core limit on concurrent processes per host:

Is this a server-side limit, or something I can fix?

possibly. I worked out on mine that if you set it to x and x days then you get rubbish delivered from the server. if you set it to x days and 0 extra then it works ok.
Seems the limit has been raised from 16 to a *massive* 20 tasks now. |

As of right now, there's over 2 million numbers in the queue above and beyond what the numbers on the front page show. Since many (most?) of those will be sent to two hosts, there's somewhere between 2 and 4 million tasks loaded and ready to go.

How often will they be updated after that? In the past it updated every 15 or 30 minutes. Considering these are short WUs it would seem less than hourly would be more prudent.

UNCHECK the LLR-PPS box for CUDA apps, and also UNCHECK the box at the top where it says "Use NVIDIA GPU".
Telling the server you want tasks for something it can't deliver to you confuses the algorithm that sends out the tasks.

That's assuming an i7 with hyperthreading on could do 8 tasks every 10 minutes, which is not likely with LLR.
Coincidentally I was doing some tests before the challenge. I didn't try 8 but thanks to avx, an i7 at 4.3GHz will do 7 of the current pps in 9:30.
Greetings from Estland. I have a PII hexa @3,6ghz, and it does a wu in 14-16 minuts, it runs 5 wus at a time and i keep one core free to feed the gpus.
I see that the challenge appears to be going well, and i wish good luck to all. |

Seems the limit has been raised from 16 to a *massive* 20 tasks now.
In version 7 of Boinc the numbers are more literal, meaning if you set the minimum to 3 days you will get 3 days of work and get more work when it goes under that. But if you add say 0.50 days to the additional work box, then you will approx 3.5 days of work when you get work. AND then you won't get any more work until it comes down to the 3 day minimum in the example above. I keep mine, normally, at 0.75 days as the minimum and 0.25 days additional, that gives one day of work and after finishing 1/4 day it gets more. |

Scores will be kept for individuals and teams. Only work units issued AFTER 5 October 2012 18:00 UTC and received BEFORE 6 October 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.
If I'm not mistaken, the scores are being credited on the challenge scoreboard a different way (using boinc credit instead of "prime score"). This will produce very flawed results.
Additionally, only already validated tasks seem to be added to the challenge scoreboards, so the final results can differ a lot from those we will see in less than two hours.

Main difference relays on the boinc scoring system. Some hosts get 2.5 credits per WU while others get almost 30 boinc credits. People who got down on the scoreboard should be those who have higher boinc credits per wu.

Yes, I would like to know that and the following:
How many work units were completed as part of the challenge?
How many primes were found during the challenge?
How much did we increase n by?
What range will we transition to now that the challenge is over?

Here's what I think is happening, based on a not-entirely-authoritative knowledge of how the work generator operates. (Specifically, I've looked at the database and the scripts, but I've never asked Rytis or Lennart if my understanding is correct.)
At the start of the challenge, Lennart loaded the server with 2 million PPS numbers. This is the pool from which work units are created.
We still have about 1.2 million of those, still in the pool, waiting to be turned into work to be sent out through BOINC.
Tasks are not sent out to your computers directly from that pool. There's another queue of work units and tasks from which BOINC sends work to your computers. The number of tasks in this queue is what you see in the front page.
The work/task queue is heavily used by BOINC, and there are speed benefits to keeping this queue relatively small. That's why we don't just dump all 2 million PPS numbers right into the work queue.
There's a process that runs periodically on the server which checks to see how much work remains in the work/task queue. If it's low, it adds more work from the pool of 1.2 million PPS numbers.
The size of the work/task queue is normally 1000. For the challenge, Lennart raised this to 200,000 because we needed a huge buffer for all the computers who were going to grab work. It's back down to 1000 now.
If you think about what I just described, if an unexpectedly large demand comes in, it's possible to exhaust the work/task queue and empty it completely. A short period of time would then elapse until the work generator process runs again, which would refill the queue.
So when you got "no work available" it was simply a temporary outage. Chances are that very shortly after that, the work queue was automatically refilled. Since the BOINC client on your computer will automatically try to get work again after a delay, no human intervention is needed AND nothing is lost -- as long as the work cache on your computer is larger than the time your client waits before trying to get work again.
That being said, we appreciate every time someone points out that something ran out of work! Thank you!

I think I need HELP!
All computers are running the RIGHT PROGRAM but after 20 hours my name and work points don't show up.
WHAT Gives!

You did not download, finish and return any of the units during the time the challenge was on (October 5th 18:00 UTC till October 6th 18:00 UTC)

Thank you for helping with the clearing of unpaired WUs from the challenge!!
I understand your problem, I will probably do the same sometime since these 18z challenges actually start at 4AM the next day for me.

@Admins - congrats on a well run challenge that I'm sure stressed the whole system.
@Cows - congrats on your 2nd place finish
@Aggie The Pew - well done mates !!
edit: @Lonnie, all is not lost - you found at least 1 prime :)

That is so true, and i was hoping to see the Vermin Horde toppling the Cows, oh well, better luck next time.
Btw, congrats to Peppert* for taking first place and congrats to team sici for winning this wonderful event.
Can't congratulate my self, again i failed to enter top 200. Dang, this is most depressing, but no matter, better luck next time. |

LOL thanks for the sentiment. We were so close to keeping up with them. However due to some changes in the wind and other "weather" related factors, we were blinded by the paddies. I mean, honestly, a cow as big as xray puts out some really really large paddies :)
ps - you are always welcome to the horde even if it's just for a challenge.

A great many thanks to all 1200 people who participated in the challenge, making it a great success. Many candidates were tested, a load of primes were found and many teams were on the wrong end of a cow ;)
CongRATs to sicilasgfsygflsadgfsdk (sorry, that name is completely impossible to remember :S) for managing a great victory and also to the rats for giving us a run for our money. :)
As Lennart just told me stats are final, the challenge is now well and truly over! I'll therefor unstick this thread and hope to see you all that 321 Blastoff challenge on the 321 LLR project, which will will begin 1 November 2012 18:00 UTC and end 9 November 2012 18:00 UTC
Also, the overall score of the challenges has been updated.

I have no objection to the modified scores -- I went up about 80 places!!!
My wife is grumpy, she didn't move at all.
Is there any guesstimate of when the placings will be finalised? I will keep on with PPs LLR until the backlog is cleared, then back to getting my badges guilded.
Yes, I would like to know that and the following:
How many work units were completed as part of the challenge?
How many primes were found during the challenge?
How much did we increase n by?
What range will we transition to now that the challenge is over?
I'm still looking for answers...

Yet the website says:
An Apple a Day Challenge (Reminder)
Two days left to start !!
I think it needs an update! |

That's a newspost. At the time it was posted it was correct. Therefor it does not need an update, just like the posts claiming that a recently found prime was the X largest prime of some sort does not get updated after a bigger one gets found.

And if there was someone that could give an authoritative answer, they would. I can make some guestimates, but I would like to point out that they could be way off. As in I could be 100% or more off.
How many work units were completed as part of the challenge? Lets ballpark it and say between 500.000 and 1.000.000. (Best guestimate is in the general vicinity of 740.000)
How many primes were found during the challenge? About 60 primes have been reported to the top 5000 during the challenge. (For sure though more than 10 and fewer than 1000)
How much did we increase n by? No fricking clue as the overview doesn't load. Though the PPS Progress thread suggest it went from 1.01M to 1.017M.
What range will we transition to now that the challenge is over? Smaller k, larger n after the buffer is empty I would expect though again this is nothing I can say for sure nor anything I have any actual influence on.

We may need to come up with new procedures to gather those statistics. This time around, however, it's likely that the statistical information is lost. As you may have noticed, we had severe problems with the server AFTER the challenge.
This happened because the database of work units and tasks was just too large. During a challenge automatic purging of work units and tasks is disabled because we need them to all be there to compute the final standings. Because of this, the database continues to grow after the challenge. As soon as enough results were returned so that the standings were finalized, automatic purging was turned back on.
That had to be done as quickly as possible. Not only was the PrimeGrid BOINC and web servers affected, but half of the PRPNet ports were shut down completely in order to lighten the load.
Therefore, we don't have -- and probably can't get -- that information. I was reluctant to run the type of query necessary to get that information since it would have likely created another server "crash".

I remember John always providing statistics almost immediately after challenges, although most would have been smaller ones where we wouldn't run into the huge number of PPS tasks. What RDMS is the backend run on?

The biggest problem is probably operational: This is a volunteer organization with, except for Jim and myself, probably no two people are within 1000 miles of each other or even in the same time zone.
Coordination is an issue and sometimes you just run into a scenario where everyone though someone else was doing it.
Although that's likely to happen in the future on other items, we'll make sure and get the stats going forward.
