Welcome to the Winter Solstice Challenge
Yes, the servers are located in the Northern Hemisphere; therefore, we'll observe winter. However, the Southern Hemisphere will be experiencing the Summer Solstice.
NOTE: This will be the last Challenge in the 2008 Challenge Series.
PrimeGrid's Challenge series continues with the Winter Solstice Challenge. Please come join us in observing Nature's ending/beginning of a cycle. A 4 day (96 hour) Challenge is being offered on PrimeGrid's Prime Sierpinski Project (Sieve) application.
The Winter Solstice...a predictable event in nature that has occurred for billions of years. A way point in the cyclic motion of the Universe. Many of the today's major winter festivals and celebrations can trace their origins back to this event...the longest night of the year (or the shortest day).
We'd like to wish everyone a Happy Holiday...whatever festival or celebration you may observe.
Sticking with the theme of origins, a good prime search can be traced back to a good sieve. Here's to all the sievers who forgo the glory of prime finding and partake in that lonely adventure of finding factors. Without them, prime finding would be an EXTREMELY time consuming task.
To participate in the Challenge, please select only the Prime Sierpinski Project (Sieve) project in your PrimeGrid preferences section. The challenge will begin 17 December 2008 12:04 UTC and end on the Winter Solstice 21 December 2008 12:04 UTC. Application builds are available for Linux 32 & 64 bit and Windows 32 & 64 bit. Note: 64 bit Windows and 64 bit Linux benefit from a 1.7X speed advantage over 32 bit...so 1.7X the credit. :)
Recommendation: The PSP (Sieve) application requires a one time download of a 10MB sieve file. Please consider running a few PSP WU's before the Challenge begins so your client will already have the sieve file. This way, bandwidth can be used to deliver WU's instead of the sieve file. :) Thank you!
Here's a link to one of many time zone converters: The World Clock - Time Zone Converter
Scoring Information
Scores will be kept for individuals and teams. Only work units issued AFTER 17 December 2008 12:04 UTC and received BEFORE 21 December 2008 12:04 UTC will be considered for credit. Since this is a fixed credit project, we'll be using cobblestones for scoring.
About the Prime Sierpinski Problem
Waclaw Franciszek Sierpinski (14 March 1882 - 21 October 1969), a Polish mathematician, was known for outstanding contributions to set theory, number theory, theory of functions and topology. It is in number theory where we find the Sierpinski problem.
Basically, the Sierpinski problem is "What is the smallest Sierpinski number" and the prime Sierpinski problem is "What is the smallest 'prime' Sierpinski number?"
First we look at Proth numbers (named after the French mathematician François Proth). A Proth number is a number of the form k*2^n+1 where k is odd, n is a positive integer, and 2^n>k.
A Sierpinski number is an odd k such that the Proth number k*2^n+1 is not prime for all n. For example, 3 is not a Sierpinski number because n=2 produces a prime number (3*2^2+1=13). In 1962, John Selfridge proved that 78,557 is a Sierpinski number...meaning he showed that for all n, 78557*2^n+1 was not prime.
Most number theorists believe that 78,557 is the smallest Sierpinski number, but it hasn't yet been proven. In order to prove it, it has to be shown that every single k less than 78,557 is not a Sierpinski number, and to do that, some n must be found that makes k*2^n+1 prime.
The smallest proven 'prime' Sierpinski number is 271,129. In order to prove it, it has to be shown that every single 'prime' k less than 271,129 is not a Sierpinski number, and to do that, some n must be found that makes k*2^n+1 prime.
Seventeen or Bust is working on the Sierpinski problem and the Prime Sierpinski Project is working on the 'prime' Sierpinski problem. The following k's remain for each project:
[u]Sierpinski problem[/u] [u][i]'prime'[/i] Sierpinski problem[/u]

[b]* being tested by Seventeen or Bust[/b] Fortunately, the two projects combined their sieving efforts into a single file. Therefore, PrimeGrid's PSP sieve supports both projects.
What is sieving?
Sieving is the first step to prime finding. In general, a sieve separates wanted/desired elements from unwanted material using a tool such as a mesh, net or other filtration or distillation methods. The word "sift" derives from this term. (Wikipedia - Sieve)
In PrimeGrid's case, the desired elements ultimately are prime numbers and the unwanted material are composite numbers. Our tool of choice for PSP sieve is Geoff Reynolds' sr2sieve program. It eliminates possible candidates by removing numbers that have small factors. As this process is much faster than primality testing, it is good to thoroughly sieve a data set before primality testing.
Sieving removes many candidates at the beginning. However, the deeper the sieve goes, the slower the rate of removal, till eventually sieving removes candidates at the same rate as primality testing. This is sometimes referred to as "optimal depth". Primality testing is recommended at this point.
There are many factors that determine how much time and how deep to sieve. After sieving, all the remaining candidates must be primality tested to determine their "prime" status.

About the Winter Solstice
32 bit OS with 64 bit CPU
This is for those who are "driving with the hand brake active" (running a 32 bit OS on a 64 bit machine) ;) Wubi is a very nice tool that installs Ubuntu as a dual boot to your 64 bit machine. It's as simple as adding a program to Windows. You can even uninstall it like you would any other program. :)
Wubi - Ubuntu Installer
After getting 64 bit OS running on your machine, here's a link to ALL BOINC clients (including Linux x64): http://boinc.berkeley.edu/download_all.php If you are new to Linux and need help getting set up, let us know.
It really is simple. :)
Ubuntu has a power save feature that throttles the CPU frequency down to save power. It does not treat BOINC as an active program so will throttle down thus causing under-performance. For those downloading the latest Ubuntu 8.10, please follow these directions to make sure the frequency is not throttled down while BOINC is running:
1. In Ubuntu, right click the top menu bar
2. Select add to panel
3. Select "CPU Frequency Scaling Monitor"
4. Click add
This will add a processor icon to the top menu. Click on the icon and set to "Performance". This also allows you to see the CPU frequency.

While finding the occasional prime is nice, I love sieving. Finding factors, while not as glorious as finding primes, will find it’s day in the Sun. as well.
Still, I am a little ambivalent about this challenge.
I love longer challenges (I run marathons) but still have doubts about things. Some folks (especially our anonymous donor) worked very hard to provide the new server. But, it performed somewhat less than ideally.
I am not a technically orientated person, (lots of folks in other projects can attest to this!) but I do value results.
So, I will be on board for this one. But there had darn well better be work for my lowly computers to crunch,
(Apologies if I seem a bitch but, well, I could be wearing shiny new shoes at the moment. LOL)

Yes, server/project was pushed to the limit during last Challenge.
I wouldn't be so worried this time. PSP Sieve takes longer and even longer on 32-bits. Server load on work generator, validator and db would be less of what we have seen.
It may be a bit demanding on start due to bandwith from those who have not done PSP Sieving (ever or in last couple of months) to download ~10MB sievefile.
I can imagine a recommendation to "burn-in" for upcoming Challenge to spread the bandwith load.

I'm in for a bit of fun-- see if I can improve on 159th--
I had no problems during the last challenge (well- only a few caused by myself)-- might see if I can gather up some old bits & pieces and make another host for the event-- (141st sounds good to me) |

Yeah, once you download your first PSP WU, sievefile will download automagically.
When we started PPS Sieve, there was ~400MB file. It was possible to download it manually and copy over other hosts in a farm in order to save other download. I guess no need for this in PSP Sieve.

Somebody considered to prepare live CD with 64-bit BOINC and PG?
I've like six 64-bit quads...there are more quads and C2Ds to attach but it is not as effecient with 32-bit so I'm considering to put them on Challenge or not....

What is the difference in times between 32 vs 64 bit? It would be better to do this challenge with 64 bit? I have another Hard drive with xp x64 this would be better for me to use? If so I'll run out my cache and est up 64 bit for this. Thanks, Jack |

Jack, how about:
Sieve PSP 32 bit: 1300 sec (22 min)
Sieve PSP 64 bit: 785 sec (13 min)
In this perspective, 64-bit should look attractive...

We completely agree and are doing the best we can. While it may look as though the new server has performed "less than ideally", it is good to point out that during the last Challenge, it handled 4X's more work than the old server could only dream about. Although, that's little consolation to those who did not get work.
We continue to look for ways to optimize the server to handle the high loads of the Challenges.
I can imagine a recommendation to "burn-in" for upcoming Challenge to spread the bandwidth load.
This is an excellent suggestion. I'll add it to the first post.
What is the difference in times between 32 vs 64 bit?
Since the last PSP (Sieve) Challenge, a new 64 bit version has been released which widened the gap between 32 bit and 64 bit times. Therefore, I have changed the first post from 1.5X to 1.7X.

Are we using a 24-hour clock to tell people when the challenge starts? If that's what is generally done on this forum, then I apologize for spamming the boards, but I can't figure out if you mean a little after noon or a little after midnight.
It doesn't matter in my case, since I intend to start crunching this sieve tonight, but some people may be a bit miffed to not know whether it's AM or PM.
If I manage to track down the information, I'll edit this information. Unless, of course, someone beats me to posting the answer here. :) |

Edit: Lol, just noticed the countdown. I'd seen it before, but had temporarily forgotten about it. So it's 4 minutes after noon, Greenwich time, which is 5am Eastern United States time.

As stated in the first post of this thread this is a Solstice Challenge and starts exactly 4 days before Solstice.
If you want to know what time it is where you live,
just have a look on Solar Data and you see in December the Solstice in your Time Zone.
Count down 4 days and be prepared ....

That's the way to go - gives you the best of both worlds, with plenty of sieving power. Remember to Open the gconf-editor, go to /apps/gnome-power-manager/cpufreq and check the box consider_nice.

Greetings Warped,
My times per WU went from 20 min. to 18 min. then started climbing to 30-34 min. Being new to Ubuntu I was messing around all day as in the system monitor the cpu usage fluctuated wildly . I tried a mild O.C. to speed them up and it didn't help. I found something a little while ago and unchecked cpu freq. and now my times are a little over 13 min. per WU. Maybe someone with knowledge can start a thread and post tips and tricks to help others? I am new to Ubuntu as of the other day and have been pulling my hair out.
I have BOINC and Prime Grid going smooth now but am unsure if it will do the cpu freq. after a reboot. Where is the gconf-editor?
I don't need to reboot and will leave this running till the challenge is over.
Thanks,Jack |

Greeting Uli
Because you are running 32bit Vista, instead of 64bit Vista.
You can get the 64bit speedup by installing Wubi as outlined above.
or
If you meant why is the reported speed so different, different OS and BOINC versions report different numbers, and you can't often compare them, unless you know the OS and BOINC versions are pretty much the same.

My Q6600, which I just put Wubi on measures like this:
Measured floating point speed 2922.16 million ops/sec
Measured integer speed 12382.35 million ops/sec
It is OCed to 3.006, but was running at that speed without any messing in Ubuntu.
The same chip, in XP 32 bit measures like this:
Measured floating point speed 3262.89 million ops/sec
Measured integer speed 9958.12 million ops/sec
Are you sure that you got the 64 bit version? It defaults to 32 bit when you D/L the .iso of Ubuntu...

I dunno. I just downloaded what was at the end of the link provided earlier. :)
The problem is that I can't find where this cpufreq file is supposed to be.
It doesn’t exist under apps: Here is a screenshot of how far I got
There is something about in the schemas/apps/cpufreq_applet/prefs but that is where the trail ends: those settings can’t be changed.

That's the problem. I think that gives you the 32-bit version. Try this link, and make sure you click on the 64-bit version of Ubuntu 8.10. That .iso has Wubi in it, and after burning the .iso to CD, it should load the Wubi installer. If not, eject and reinsert the CD. That should get you going with the 64-bit version. |

According to your computer details, you have Linux 2.6.27-9-generic, which is the 32-bit version.
Try again and select the 64-bit one! |

Okay, before I waste hours doing this again, let me make sure I got it right:
The Wubi Installer link in John’s earlier post is the wrong one.
And I should be using the link in John Galt 007’s post instead..
Right?

Well, I am back with XP and other projects for the moment. If I have time I'll have another go at it before the challenge.
And if not, such is life. :)

my 64bit Kubuntu and Ubuntu Linux has the same Kernel 2.6.27-9-generic
so you can't see it based on the kernel version

I am unaware of any issues with Wubi installer. I'm typing this from a Wubi installed 64 bit machine. :) Additionally, kenzieB, it appears you have downloaded the 64 bit version. Otherwise, 64 bit BOINC would not be running on your machine. Also, from your completed WU's, you can see that you're using the 64 bit app.
BOINC sr2sieve 1.07 wrapper
Using Geoffrey Reynolds' sr2sieve 1.8.2 (64bit)
from http://www.primegrid.com/result.php?resultid=77123244
Unfortunately, I'm not able to help with the throttling issue. Hopefully someone will see this and provide some input.

That's not how wubi works - if your h/w is 64bit capable, that is what it installs - it does not give you the option, nor is there a seperate download.
To confirm, open a terminal (Applications -> Accessories -> Terminal) and issue the 'uname -m' command - you'll get x86 for 32bit, and x86_64 for 64bit.
Re: cpufreq - I don't run 8.10 so I can't check, but the 8.04.1 wubi install works just fine:

Hi Kenzie I am new to UBUNTU and am using 8.04. I downloaded and ran 8.10 live and figured out how to help you. Right click the menu bar,click add to panel,click cpu freq scaling monitor, click add. That will add a little processor icon. left click that and set to performance. This worked in 8.10 for me, This should help you crunch faster.
Good luck, Jack

Apologies - looks like I sent you on a wild goose chase and then went to bed!
By trawling through the Ubuntu forums I got the impression that 2.6.27-9-generic is 32-bit. It must be 8.10.
I also run 8.04 (specifically 2.6.24-22-generic) and have not had a problem.
Looks like Jack's got the subject sorted - thanks. I'll probably switch to 8.10 after the challenge as well.

I think that I have things figured out. Sort of.
2 cores are crunching wu’s in 14m35s or so. The other two are still taking approx 22 minutes. Anyway, at least I now know that Ubuantu 8.10 is 64 bit and my computer is running at 2.4 gHz indicated.
Thanks to John, Warped, John Galt 007, Matthias Lehmkuhl, Vato and especially THANK YOU JACK!.
I now return you to your regularly scheduled thread and will consult my other computer Guru’s at Seti to sort out the rest of my issues.

I notice that in the past several days, over 100,000 WUs for the PSP sieve have been checked out, leaving the current total around 46,000. Can we safely assume that there will be sufficient work to do during the challenge? |

|
|

for those who knows:
fc psp_sr2sieve_20080827.sieveinput SoB.dat
No difference.
Maybe removing duplicates at daily or at least weekly basis will be a good idea? Usually removing one k after prime finding increase speed. But also removing 1% of duplicates increase speed too...

This directory contains some binaries for sr2sieve, a sieve
for multiple sequences k*b^n+/-1 and b^n+/-k.
To compile sr2sieve from the sr5sieve source, just change the
defination of BASE from 5 to 0 in sr5sieve.h.
The latest stable version is 1.7.15.

C:\Program Files\sieve>primegrid_psp_sr2sieve_1.02_windows_intelx86.exe

Does this mean a new sieve input file on each update? This would mean downloading it on regular basis by thousands of computers...
I believe there will be new sieve file after Challenge is done.
I have been struglling to find out what's new in 1.7.15, some changelog.
Found MULTITHREADING feature in 1.7.x - which may sound appealing...but BOINC after those years still doesn't support multithreading.
Anyway, "this feature is experimental, known problems are:
1. Running one multi-threaded instance of the program is LESS productive than running multiple seperate non-threaded instances."
So, what are the real props for PG to go to latest app version?

The Challenge seems to have got off to a great start. Work units are flowing without a hitch. |
|

|
|

I've had great success in getting work.
On with the SHOW!!! |
|
|
|
|

I only have two cores, and both are going . This is a guess as I am new too and don't have four cores.
Right click the processor again and click the preferences,change the monitored cpu look at all the cores.
You may have to set cores (mine are core 0-1 ) maybe 2-3 to performance too. I don't know how this O.S. works and don't have four cores this is just a guess.
Good luck all in the challenge , Jack |

Yes - a good start - in fact, the best challenge start ever!
I hope the per-cpu task limit is raised soon (subject to it not killing the server). Experience has taught me that having 1.5-2.0 days of cache is about right to avoid running out of work when a short series of server transaction failures causes the BOINC client to defer for 24 hours+.

We are only 1/2 guilty. :( BOINC is using the following:
- Using Geoffrey Reynolds' sr2sieve 1.6.7 (32bit)
- Using Geoffrey Reynolds' sr2sieve 1.8.2 (64bit)

We looked at a new sieve file before the Challenge and the difference was negligible.
1.8.2 is approximately 13-15% faster than 1.6.7. We are not using the -t switch for multi-threading. That is used for manual sieving. BOINC however, will make use of all cores.

I don't think there is any need to do that. Validator is running but when it finnish it is about 10k new wu'its to validate.

that's better ask to admins - can sob.dat delivers in zip format? 2 mb instead of 10.
and ofcourse theres no need to update it every time. one update per week will be enough.
and there's a few boinc projects that need a bigger downloads even often.

every new version offers slight speed increase 1-5%. you can believe me cause I sieving for sob when n < 1m ))

no flatline here atm - all is running fine - I love this contests!
btw: reactivated an old opteroncorpse with 2 native cores atm - faster than my Q6600 3,33 - but 4 cores on Tyan Thunder would damage my ears (I'm working on that with towercoolers ... ;) (Tyan-native-coolers run on horrible 6500 rpm, no ocl - its very loud in my office ...)

Flatlining meaning look at the last 1/10th of the credit scores, they don't go up anymore. Although you are crunching, you are not getting credit for it immediately, you have to wait for it to be validated.
EDIT:
I guess my 1/10th thing is wrong, my screen isn't wide enough here at work to see the entire graph...

I don't see it as a foul up, but as a delay in the statistical information. When all is done, credit will be given where due, and the challenge will be scored properly. Otherwise, a lot of work is being accomplished right now.

Well my brand new computer just arrived today, so I figure this challenge should be a good initiation test for it. Time to see what a quad core with a 64 bit os can do in comparison to my old single core, 32 bit slug. :D
Too bad I can't stay for the whole challenge though since I have to catch my flight home for Christmas on the 20th. :( |

The lowered activity in the forum is an Excellent sign...hopefully it means that everyone is content and happily crunching.
All indications point to a pretty smooth start and an uneventful time since then. We've made a few adjustments with work flow and freed up a little more resources for the validator. All seems to be working fine.
A range of over 1P has already been sent out. The current range goes up to 18.85P. At this rate, we'll easily see up to 19P (most likely completed) by the end of the Challenge. This simply is amazing!!!
Thanks for doing such incredible work!

Update
Up to 19.21P has been inserted into the buffer. The work rate continues to increase as more users join the Challenge. Most definitely record breaking progress.
Over 490K tasks are now in progress and this number continues to grow. The good news is that the validator is keeping up.
So far, almost 1500 users have received credit in the Challenge. There remain some very close races in both the team and individual categories.
Thank you to everyone participating!

Did not have to turn the heater on last night, just put a box fan in the middle of the computer room, and pointed it towards the hallway on low setting.
Hard do believe the amount of CPU being thrown at this challenge, You need 20K a day just to make top 50.
A few requests time out, but with ¼ to ½ day cache, no problems thus far. Seems to be running relatively smoothly, and we have one heck of a battle on our hands in many areas.
Great job everyone !

Update
Up to 19.75P has been inserted into the buffer. The work rate continues to increase and the Challenge continues to advance its record breaking progress. BTW, to reach 20P would be a monumental accomplishment and we are coming very close. :D
Over 515K tasks are now in progress although this number is starting to level off. The validator continues to keep up.
A few connection messages are starting to pop up but nothing consistent. Anyone with a few tasks in the cache should not notice any disruption in crunching. Most clients reconnect successfully within a minute or two. However, it is recommended to keep about an hours worth of work to be safe.
So far, over 1700 users have received credit in the Challenge. The team and individual races continue to be EXTREMELY close. It's very exciting to watch!
Only 40 hours left! Best of Luck everyone!
Thank you for participating!

This is not always true. At 12:18UTC I got: "Message from server: Server can't open database".
Automatic work requests got a delay of 3600 seconds.
So John's adviseHowever, it is recommended to keep about an hours worth of work to be safe. is wise.

Update
The validator continues to keep up.
my pending list keeps rising slowly - looks like validator simply does not like some of them hanging around there for hours.
13 of my PSP Sieve tasks still 'pending validation'. Validator queue is rather low (2299 atm).
My 2 oldest pending WU's are from 18 Dec. 18:00UTC.
Forgotten by validator?

Yeah, I'm seeing the same thing, I have 3 wu's that don't want to clear out of my pending credit queue. |
|
|

Some machines are having problems reporting work.
eg this sort of delay is unusual.
12/20/08 21:01:40|PrimeGrid|Sending scheduler request: Requested by user. Requesting 0 seconds of work, reporting 42 completed tasks
This message resolved after 2 minutes 13 seconds.

not a wild guess: everything reported while stats-updates are running, will be missed by validator and need manual intervention.
running fine... |

I am marking skipped WUs for revalidation right now.
[edit] Don't be scared by the status page numbers, there is no way to mark only stuck WUs, so I have to mark all not-validated WUs for validation, which will cause big numbers waiting for validation to show up.

thanks.
this is the first real problem during the whole Challenge.
But I have seen other projects do this also, so it is a normal annoyance |

Thank you for all the validator concerns. However, other than an annoyance, it does not impact the final results in the Challenge. Yes, stats may not be as "real time" as they should be but the outstanding un-validated WU's are relatively very small compared to the work being completed.
Rest assured that ALL RETURNED WU's will be validated before the results of the Challenge are finalized. The IMPORTANT thing is to have all completed WU's returned before 12:04 UTC 21 Dec 2008 so they can be counted. Validation will still happen after that time and we'll make sure that all WU's are validated.
Therefore, return early and return often. Don't wait until the last 15 minutes to send up a lot of results as connections will be stressed at that time.
Good Luck!

grmpf - it was only 1 or 2 % that could have been wating for the race to be done. validator has no chance to make it up @current speed.
now the fun is over - brillant idea..

Something thats starting to Piss me off is the Server keeps sending me work that I'm not requesting. I have my Box's set to 0.1 Connect Time which as far as I know I should only have about 2.5 Hours of Cache with that Setting yet some of my Box's have over 2000 Wu's on them.
I even just seen 1 Box get 35 New WU's even though I set that Box to NNW, something about Resending Lost Wu's, as far as I know that Box hasn't lost any Wu's & has been running every Wu it gets.
Once the Challenge is over I'll have to Detach the Box's because the Server refuses to obey the settings and if I don't Detach my Box's the Server will just keep sending work it looks like ... |

WOW!!! The wolves are never very far from the fire! :) As this is the Winter Solstice, we're going to throw some more logs on the fire in an attempt to keep them at bay until the sun rises...which for us is 12:04 UTC 21 Dec 2008. :)
Thanks for all the feedback. Yes, we made a side step that had unintended results. For now, we have reversed the "marking" for validation.
We will continue to monitor.

Nice to see that Kevin comes to the party too. A little late as the last time ;) but with a lot of power.

Crumbs. Is there a challenge?
I have just been dealing with the big challenge of finding 3 wise men and a virgin round here (no problem with finding asses) to find there is another PrimeGid challenge.
I didn't know I was in it and now find I'm about 250th so come on gang let see some computation done :)

Just turned in the last of my WU's and now I must catch my flight home for Christmas. Happy crunching everybody. I'll see you guys again in a couple of weeks. :) |

I've got a few boxes running on Fedora10 Live CD (64-bit). At the beginning, everything looks fine. I get about 35-40 WUs. But the next time I issue an "update" in the Manager, all of the unfinished WUs (or the ones I haven't even touched yet) become "Aborted by project". On all 5 machines. What does that mean? It doesn't happen on my 32-bit boxes...

This is a tight challenge. I hope the validator and the stats can keep running fast enough so that we see what the standing is - there seems to have been a major lag this afternoon. |

What's happening is that your client uploads the completed WU's and before the server can respond that it has received them, the connection times out. The next time your client connects it attempts to upload the WU's again. The server then gives you the correct message that they have already been reported...by you.
...and yes, you are receiving the credit for them. :)

Good for some, not good for others.
I think it's a useful tool to keep things running sweet at the start and end of challenges, as has been proven this time round. But it's not a good thing to have all the time for folks that have intermittent connectivity.

BUT quite a few of those WUs are ours!! I see they've taken the Transitioner down, and the backlog has gone to 0 hours. I guess that when they bring it back up, the validation queue will go back to normal, and we will see the final scores.

Last time no problem with top10, close to being 5th.
This time hard to reach top10 with same crunch power.
A lot of work was done during challenge.

Thank you, Seejay. :] That was our 2nd contest - last time we got the "looserrank" 31 (no points for a 1-2 day challenge). But even now we did some mistakes (wrong OS, late start, ...)
We look forward to do a better job next time ... with new extraterrestial engines and reactivated Server-Corpses. ;)

I am absolutely amazed. This challenge was so much more fun that I could have imagined. I lost a lot of sleep keeping my eye on the stats too.

The results are in!
The results are final, in what turned out to be PrimeGrid's closest and most contested Challenge yet. The margin of victory was razor thin...only 0.055%...about 65 WU's out of almost 1.9M WU's completed (3.5 hours worth on a quad). The delay occured because the few remaining pending WU's had to have manual intervention to clear. Rest assured there were no hanging chads or dimples or any of that other nonsense that plagued the 2000 US elections. :D Unlike those results, these are true.
263 teams and 2112 individuals participated
The Challenge Points stats are official. Congratulations to BOINCstats as the top team and WilliamWallace as the top individual. Remember, the top 35 places earn points for this Challenge. An additional congratulations goes out to everyone involved. What an AMAZING Challenge this was.
This concludes PrimeGrid's 2008 Challenge Series. Overall final results will be posted soon.
Thank you again to everyone. We appreciate your participation and hope you had fun! We wish you a Happy Holidays and see you next year!

Wishing you all a Happy Holidays and offering up a toast to many future challenges!
Note: happiness during the holidays does not necessarily need to involve the acquisition of new computer(s) or other devices capable of running Boinc.
