Welcome to the Marie-Sophie Germain Challenge
Marie-Sophie Germain was born on April 1, 1776, in Paris, France. She was an extraordinary "French mathematician who made important contributions to the fields of differential geometry and number theory and to the study of Fermat's Last Theorem." (Wiki)
Because of the gender prejudices of the time, her early work was submitted under the pseudonym of M. LeBlanc. Later work was finally submitted under her own name and on 8 January 1816, she became the first woman to win a prize from the Paris Academy of Sciences. While some consider her work lacking in rigor, almost all agree that it was from the lack of a formal education that was denied to her based on her gender.
The modern view generally acknowledges that although Sophie had great talent as a mathematician, her haphazard education had left her without the strong base she needed to truly excel. Louis Bucciarelli and Nancy Dworsky, Germain's biographers, summarize as follows: “All the evidence argues that Sophie Germain had a mathematical brilliance that never reached fruition due to a lack of rigorous training available only to men."(Wiki) What better way to pay tribute to Sophie Germain than to find a prime with her namesake. Finding a World Record Sophie Germain prime would be incredible and even more amazing if it was found during the Challenge. :) Hey, it's possible. NOTE: A twin prime is also possible in this search because of the quad sieve.
While the Sophie Gemain prime remains elusive, a byproduct of the search are single primes. The last SGS (LLR) Challenge found over 100 of these. We expect about the same this time around.
A 2 day Challenge is being offered on PrimeGrid's Sophie Germain Prime Search (LLR) application. To participate in the Challenge, please select only the Sophie Germain Prime Search (LLR) project in your PrimeGrid preferences section. The challenge will begin 1 April 2012 18:00 UTC and end 3 April 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 ~15 minutes on fast/newer computers and 25+ 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.
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 1 April 2011 18:00 UTC and received BEFORE 3 April 2011 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 Sophie Germain Prime Search
A prime number p is called a Sophie Germain prime if 2p + 1 is also prime. For example, 5 is a Sophie Germain prime because it is prime and 2 × 5 + 1 = 11, is also prime. These numbers are named after Marie-Sophie Germain, an extraordinary "French mathematician who made important contributions to the fields of differential geometry and number theory and to the study of Fermat's Last Theorem." (Wiki)
We'll be searching the form k*2^n-1. If it is prime, then we'll check k*2^n+1, k*2^(n-1)-1, & k*2^(n+1)-1. We are able to do this because a quad sieve was performed for this search. This sieve ensured that k*2^n-1, k*2^n+1, k*2^(n-1)-1, & k*2^(n+1)-1 did not have any small prime divisors. The opportunity to find SG's and Twins in the same sieve file is appealing. However, we "expect" to find a Sophie Germain prime first.
This quad sieve was prepared quite some time ago; so it was readily available. Here are some stats for the search:
k range: 1<k<41T
n=666666 (actual 666666-666685)
sieve depth: p=200T
candidates remaining: 34,190,344
Probability of one or more significant pair = 80.1%
Probability of one or more SG = 66.7%
Probability of one or more Twin = 42.3%
Approximate WU length:
Athlon64 2.1Ghz - ~2000 secs (~33.3 minutes)
C2D 2.1 Ghz - ~1015 secs (~16.9 minutes) per core
C2Q 2.4 GHz - ~880 secs (~14.7 minutes) per core
C2Q 3.2 GHz - ~600 secs (~10.0 minutes) per core

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: born 1929).

Welcome again to PrimeGrid's 2012 Sophie Germain Challenge.
We are searching for primes about 200700 digits long. Primes of this length are of themselves interesting. There is a decent chance of a modern computer running throughout the challenge finding such a prime.
The real prize however is that the primes you find might be Twin Primes (p and p+2 are both prime) or Sophie Germain Primes (p and 2p+1 are both prime). Finding either of those would ensure you long standing fame.
So come along please and enjoy the PrimeGrid Sophie Germain challenge starting 1800 UTC 1 April 2012 for 3 days. |

It always amazes me that people on a maths based project can keep on hoping when they must know the odds are so heavily against them!!
I guess I am another one of them.

Sophie Germain Primes is to low to enter first 5000 primes , so I doubt it will give you a fame :)
Twin Prime can be fame number :)

"Sophie Germain Primes" and primes found at Sophie Germain subproject are not the same. Those primes being found on a daily basis on the SGS subproject - that are now too small to enter top 5000 list - are not SGS primes, but just (regular) prime numbers. The largest Sophie Germain prime known so far would not enter the top 5000 list: it has less than 80,000 digits. Additionally, none big enough to enter the top 20 has been found for over two years, so finding one would give you some fame...

The cows will be heavily crippled since our annual stampede also begins on April 1.
Some cows will be here I believe but most of the power will be on Docking, so the rats have a big opportunity to create a gap!
Good luck too all and we will be back in full force at the next challenge.

Remember Arjant, it's not always the number of participants that counts. Am sorry to hear the cows will be "mostly" absent but understand and look forward to the next full head to head challenge.
Of course, tipping of cows is fun no matter the number :)

I got 7 wu`s at the first minute - then totally stop. And those didnt last long, of course. ;-)
But yes, i checked the settings - just to be sure its not jumping around of itself in there -
and all is correct. ;-) So.................. i think the server doesnt like Norwegian coconuts. ;-p

Server load seems a bit high, site is not too responsive but i get work every now and then plus i am able to report. WUs waiting for validation is climbing up, but that's what was to be expected.
Any idea when the individual stats are pouring in? |

Hello everyone!

I ended up increasing my work buffer a little to help ease the network congestion, after spotting that a machine displaying communication had been deferred for another 30 or so mins, thankfully now I've enough WUs to keep me from being idle.
Happily crunching away again :)

I don't know what the server issue is, but I keep finding my fastest system only running 2-6 tasks on a 32-core system, with the rest of the downloads in a 15-minute backoff. Increasing the work buffer doesn't seem to help. I get the message that internet connection is fine but unable to connect to servers. Very frustrating. |

I am getting "No work available for the application" constantly.

I'm getting work but none of it is being validated. Even the 321 with both results in is still waiting.
Is the validator running? Does it stop to allow better server loading in the chellenge?
I have not had enough work done to notice before.

If you noticed, the PrimeGrid website itself is loading very slowly.
There was a similar issue a few months back with another challenge (I believe on PPS LLR) - basically, the challenges involving copious amounts of smaller, shorter workunits tend to flood the validator. Though to the best of my knowledge, there's much done in the ways of preventative measures.
Even so, we may just be seeing validator issues. Feeder too, perhaps, but I'm getting work now. Took me complaining for the server to realize my fastest host was out of work... :P

Hello,
looks like the 32bit and 64 bit boxes are getting WU differnt.
My 32bit box everything fine, my 64 bit box is out of work for more than 6h
now.
Also the upload for 64 bit is different, within a time frame of less than 10sec
the 32bit box is able to sent WU results, the 64 bit box isn't.
Any ideas what happens ?

Being able to get and send wu's is currently a bit random. With this challenge the servers get hammered with tons of connections every second of people trying to get or send work units. One second it's too many people for the server to handle new one, the next it's fine.
Also, I wouldn't be surprised at all if the validator has been shutdown for the duration of the challenge. During a challenge it's more important to make sure that everybody has work to than to get the returned work validated, as the goal of the challenge is to do as much work as possible. Waiting two days for your units to be validated is by far not as bad as seeing your systems run dry every other hour because the server is unreachable due to high load.

Well, I woke up to my fast system running 0 tasks with 1 download pending with a 10 minute retry delay. The client-server logic seems to be broken for machines where all tasks can be completed within 15 minutes. One download timeout appears to block any further downloads from being requested; looking in the logs I see that completed work was uploaded during that timeout, 20+ threads idle, "not requesting new work". Even when I retry the download and it completes, it only requests 4 more tasks even though 32 threads are idle. So, on this system, I'll be completing a few tasks every 15 minutes, with about 10 minutes of completely idle time during that 15 minute period. |

Since my two machines are almost always running SGS, I usually don't notice (or care) that things are running differently. But in a challenge, everything is always a bit off.
What irks me is the number of people who don't know there is a challenge, get a pile of WU's, and then their machines switch to some other project, leaving me with tons of double- and triple-checks to carry out. I prefer virgin numbers.

Well what can i say, work available is plenty: Available: Sophie Germain Prime Search (LLR) 148967
My 3 different rigs, regardless of the manual buffer size, have equal amount of wu-s downloaded? Intel i3 and Athlon II x4 are safe cause they are so slow, but PII x6 at 3,9 ghz, com's close to runnin out of wu-s when theres a project backof goin one. So i'm imagining that all thouse really fast system's will run out of wu-s on a regular basis.
I think that is due to the limited cache size from the server side. Recommend atleast 15 wus per core for fast systems, beginning with 8 cores and up, and all i7 cpus. For normal systems it should remain the same. |

yes, pretty ridiculous that we can't fetch more than 45 minutes work when constantly getting 1 hour back-offs due to the servers getting hammered.
As a result my score after 24 hours was about half of what it should have been (or should I say, would have been on any other day)
I really think the "powers-that-be" need to rethink these short wu challenges while the infrastructure is not in place to handle them as all they end up doing is, to put it diplomatically, annoying participants.

Consider this: this is the first challenge in which avx apps are widely available (i.e, without the need op app_info) for everybody who has a proper cpu, which puts extra load on the server, as the run times get lower.
There is a workaround to server back-off (updating manually). That can be really annoying if you have a big farm or if, by any other reason, you do not have the time or the will to be babysitting your hosts. So, if you just turn on your machines and get back when the challenge ends to collect your results, the outcome is unpredictable. Having the most modern (and numerous) hardware might just not be enough to beat someone with less resources, and gives smaller crunchers a fair chance of getting a better position. This fact adds some competition to the challenge, does it not?
Hey, do not start throwing me rocks :) I've also been hit hard by the back-offs.
I just think it is unfair to start shouting at the admins because Primegrid does not have (can not afford?) a state of the art server (that, in fact, would be useless most of the other 364 days of the year): the server has not crashed, despite the amazing number of tasks being crunched. I think boinc is set to wait longer and longer when an attempt to connect the server fails, if you happen to be unlucky when connecting to it at the same time as hundreds of hosts. So, maybe, you should complain to the boinc developers instead, asking them to add an option to manually set the time between attempts to connect to the server (although this could lead to a true server crash).
Keep in mind what you can actually buy with boinc credits (or even with challenge credits) and enjoy.
Anyway , if someone thinks a new server is mandatory, then there's a way he can help it coming faster: http://www.primegrid.com/donations.php
Good luck everyone

Agreed...
At that, it seems that even with the AVX app, I'm seeing runtimes about doubled lately. Did WUs get longer somehow? Or did something go wrong on my system?

Under 4 1/2 hours remain!
Now's the time to start preparing for the end of the Challenge. We are lowering max cache as well as the buffer to help minimize abandoned WU's at the end. For those "moving on" after the Challenge AND have a full cache of work now (4 hours worth), it might be a good time to set "no new work". Make sure to update your clients early and often to get those completed WU's reported and counted.
If everyone can remember to either complete their cache or ABORT their WU's, then we'll be able to finalize earlier than later.
If you have the resources, please consider helping in the "clean-up" process after the end. However, we fully understand the need/desire to "move on."
Good Luck to everyone as we finish these last few hours...
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. :) |

well someone has a sense of humour. Be good if I could actually get a queue of work units to abort but yet again my PCs have been sitting idle for half this challenge and even when they get work it's usually only enough for 20 minutes of processing. |

I took part with 10 real CPU's no Hypertreading and got always enough work.
I had have no problem during this challenge.

Wow, I appear to have 3248 pending workunits... This is going to take some time to validate. I'll be staying on this sub project for a while so I guess I can look forward to receiving lots of resends and timeouts now ;-)

it does, a huge amount to chew on.
but you can allways donate some bucks to buy more ram for the server. ;)

The best we can do now is to do some bigger work so the validator can get more CPU power. I run TRP LLR now to easy the load on Boinc server.

you know that' it's not lack of CPU-power, but transaction time due to a huge DB on a host which has not the I/O capacity to handle that.

A good challenge. Niether myself nor my wife (Shahida) ran out of work after the first 10 minutes, but we will have to be patient for the validator.
I am not sureif the team stats count returned work or only validated, I think it is returned. If so then AUSTRALIA has some challenge points for the first time!

It counts returned work, however, if the work eventually gets invalidated, those points will be subtracted. Therefore, points get credited as soon as work is returned, but is not finalized until the work is validated.

The ranking show me at place 206
206 _heinz 17772.63
I participated with 3 cpu-s, and got the place 204 (so far).
A fast cpu (i7 12 threads) will do the same work as my 3 cpu-s did, but on one host. It will chew through the small cache in no time, even faster when clocked.
Dang, i so wanted to get into the first 200, but heck i aint complainin.
Surprised and happy that the server took the load\beating and didn't crash.
It was a nice challenge overall. |

I aint complaining either, but 201st place is really odd (it is also composite).
It was indeed nice challenge. |

well guys, it was server overload...
I kept running out of work and I did not even participate in the challenge! |

Well I will be staying with this project for the cleanup and most likely beyond. I thought I had my badge on Sophie but it is the one I'm missing so I will crunch away to get it. This one take a silly # of WU for this badge.
Then all I need is to find my first prime. I don't care if it is a record I just want one!!!

*lol* lucky man - good laptop ;-)
My netbook did 16 WUs. http://www.primegrid.com/show_host_detail.php?hostid=230905 (with 12 Watt/h) But sometimes it could be important for the Teamranking. ;-)))
Any others here crunching with Atom450? *rolleyes*

So about the cleanup, how is it going? Any clue on how many results still need a (new) wingman? Or will that only become clear after the validator is done with chewing through the 1M results it had yesterday?

I suspect that, if for no other reason, they won't run the DB queries to collate that information until after the validator catches up.
For one thing, the challenge results depend on the results of those million WUs being validated. Perhaps just as important, those big queries can potentially bring the DB to its knees, and there's not much point in doing that twice -- once now, with incomplete results, and again in a day or two once the validator finishes.

There are no need for more work on SGS before the buffer gets abowe 3000 on frontpage.
We need to get all validated before we will start checking for unvalidated wu done on the challenge.
Deadline on those was two days and that means that tasks not completed & not aborted will be out again tomorrow 18:00 UTC.

Nice! :) That was one quick clean up.
Good work by any and all that participated and especially by everyone who kept the server from crumbling down. Looking forward to the next challenge in which the cows should be back with some more power.

I love the Shophie Germain Challenges.
However, I totally messed up with this one Lol.
I had SSG running with a view to gaining the next level badge when the challenge came along. Forgot to run my cache down to the minimum in time for the challenge OPPS. Lost about half a days worth on the challenge itself.
So all in all quite pleased with 268th :) Normally up around the 200-190 position.
Now I can go back to getting my First Yellow badge :)
Just a quick question:
When are you going to enable viewing the primes found again. Looks like I got 2 during the challenge. Would like to know if they were first finders or second's. :) Thanks

Yes. When will the prime pages be re-enabled since the challenge is over and finalized already. Why the delay. This happens all the time. It seems someone has to say something every time a challenge is finalized.
NM*
P.S. The 64 bit app is horrendously unstable unless priority is raised to above normal and even then, times, utilization and threading is all over the place. I can't believe this hasn't been pulled yet. Maybe because ppl put up with it for those extra few seconds faster it is for the long term average. All my multi-core CPUs are the same way. And some unexpected invalids as well. Only my lowly AMD 64 3200+ single core has any consistency and no utilization problems but had the most invalids though. Went from 100th place to 102 because of it, and losing out on the last place for series points. Running the 32 bit app without the dozens of invalids would have easily compensated for the slightly slower WU times. But at least I found a prime during the challenge.

Hi David,
it looks like you had a Seventeen or Bust (SoB) workunit running during the challenge. Due to very long estimated time to completion (esp. on a single core CPU) BOINC will treat it as having enough work in queue and will not request additional or new work. Even if you suspend the current SoB task BOINC will not request new work.
Your best bet going forward would be to start these very long workunits after the challenges and just run shorter subprojects leading up to a challenge to clear out your cache.
Hope this helps!

I am about to prepare a list of individual positions for the first two substantive challenges (ie ignoring the just for fun one we did about six weeks ago). If you were in the top 200 places in both challenges and you changed your user name between challenges would you let me know by PM please? Positions for both challenges are on the front page.
