Welcome to the Winter Solstice Challenge

The Final Challenge of the 2009 Challenge series is upon us. The Winter Solstice Challenge marks the culmination of 9 Challenges this year. And to top things off, this is the deciding Challenge to determine who wins for the year. A 3 day (72 hour) Challenge is being offered on PrimeGrid's AP26 Search application.

There are EXCITING races in both the Teams and Participant categories. The results of this Challenge will determine the overall Champions.

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.

NOTE: The servers are located in the Northern Hemisphere; therefore, we'll observe winter. However, the Southern Hemisphere will be experiencing the Summer Solstice.

To participate in the Challenge, please select only the AP26 Search project in your PrimeGrid preferences section. The challenge will begin 18 December 2009 17:47 UTC and end 21 December 2009 17:47 UTC. Application builds are available for the following:


  • Microsoft Windows (98 or later) running on an Intel x86-compatible CPU
  • Microsoft Windows running on an AMD x86_64 or Intel EM64T CPU
  • Linux running on an Intel x86-compatible CPU
  • Linux running on an AMD x86_64 or Intel EM64T CPU
  • Mac OS 10.3 or later running on Motorola PowerPC
  • Mac OS 10.4 or later running on Intel
  • Mac OS 10.5+ running on an Intel 64-bit CPU
  • Solaris 2.8+ on an AMD x86_64 or Intel EM64T CPU
  • Cell/BE Linux (Playstation 3)
  • GPU (32/64 Windows & 64 Linux) - a CUDA23 application has been released. Please see more information here.


WU times (These need to be updated. Please post your current WU times in the AP26-runtimes for different apps and architectures thread.) All I did was double the last challenge times.

Elite: 16-20 minutes
Fast: 26-30 minutes
Average: 40 minutes
Slower: 60-80 minutes
Slowest: 120+ minutes

For a list of "notable" AP's found by PrimeGrid, see the AP26 Stats page. For an extensive list of record AP's, please see Jens Kruse Andersen's Primes in Arithmetic Progression Records page.

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 18 December 2009 17:47 UTC and received BEFORE 21 December 2009 17:47 UTC will be considered for credit. Since this is a fixed credit project, we'll be using cobblestones for scoring.

Credit is currently set at 23.61 cobblestones per WU.

About the AP26 Search (Arithmetic Progression of 26 primes)

An arithmetic progression is a sequence of numbers with a common difference between any two successive numbers in the sequence. For instance, the sequence 3, 5, 7, 9, 11, 13, 15, ... is an arithmetic progression with a common difference of 2.

Therefore, an arithmetic progression of primes is a sequence of primes with a common difference between any two successive numbers in the sequence. For example 3, 7, 11 is an arithmetic progression of 3 primes with a common difference of 4.

For an arithmetic progression (AP) of primes, AP-k is k primes of the form p + d*n for some d (the common difference between the primes) and k consecutive values of n. The above AP-3 is 3 + 4*n for n=0,1,2.

n=0; 3 + 4*0 = 3 + 0 = 3
n=1; 3 + 4*1 = 3 + 4 = 7
n=2; 3 + 4*2 = 3 + 8 = 11

Another example is the AP-10 of the form 199 + 210*n for n=0..9. This produces the following sequence: 199, 409, 619, 829, 1039, 1249, 1459, 1669, 1879, 2089.

AP-k is also sometimes notated PAP-k (Primes in Arithmetic Progression).

We are searching for the longest AP, not the largest. The current record is an AP25 discovered 17 May 2008 by Raanan Chermoni & Jaroslaw Wroblewski. PrimeGrid tied the record by finding an AP25 on 8 Apr 2009 (BOINC@Poland, PrimeGrid, AP26). For a complete list of records including longest and largest AP's, please see Jens Kruse Andersen's Primes in Arithmetic Progression Records. Also, a list of the top 20 largest AP's can be found at The Prime Pages: The Top 20

Jaroslaw Wroblewski's AP26 code will be used for the search. Geoff Reynolds adapted the program for use with BOINC and for compiling without GMP. Several others have contributed to improving the code and porting it to other platforms.

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.

For those that are looking to tweak their computers for the final challenge, here is some information on the fastest AP26 computer setup with current apps:

Intel Core(tm) CPU, 64bit Linux distro such as CentOS or Red Hat Enterprise, and multiple Nvidia CUDA video cards.

My example machine, just setup today:
http://www.primegrid.com/show_host_detail.php?hostid=122106

Intel Q6600 @ 2.4 running CentOS 5.4 with 2 gpus: GTS240, GTS250... about 14,000 credits/day


Anyone running multiple GPUS should certainly switch to CentOS/RedHat since the CUDA application runs the fastest, with a small amount of CPU used to feed the GPU. Also, I find that the Nvidia driver installer just "works" without any problems.


The Windows applications for CPU are using the same code and compiler as the Linux versions, but when timed they are slower on the same hardware. The Windows CUDA application is slower than the Linux version due to changes necessary to get the GPU to run with a fully loaded CPU.

I hope this helps anyone looking to optimize their "farm" for AP26!

Bryan

Scores will be kept for individuals and teams. Only work units issued AFTER 18 December 2009 17:47 UTC and received BEFORE 21 December 2009 17:47 UTC will be considered for credit. Since this is a fixed credit project, we'll be using cobblestones for scoring.

Credit is currently set at 35.41 cobblestones per WU.

Stats will be available on the front page next to the timer within 30 minutes after the start.

What to expect at Challenge start

The server always gets hit hard at the beginning of the Challenge. However, a procedure that we've been using for all the Challenges this year has been very successful so far, and we hope it holds true for the final Challenge. A few hours before the start (18 December 2009 17:47 UTC) "max cache" will be dropped to 16 tasks per core. Additionally, "max to send" will be dropped to 8 tasks per core. Anyone attempting to request more will be met with "max cache" messages.

We'll load at least 500K into the buffer. At the start of the Challenge, these settings will be adjusted as necessary. However, if the past year is any indication, we'll make the first adjustment around 30 minutes post start by raising "max cache" to 32. We'll continue to increase "max cache" when the server can handle it until a full 3 days max cache is possible.

This method allows the greatest opportunity for the most clients to get work. Even if it's just 1 task for the first 10 minutes, at least the client is crunching. Past Challenges have shown that clients have a good chance to reach "max cache" before their first task is complete. We expect the same this time.

Strategies for starting the Challenge

Depending on a variety of factors, different strategies work for different users. Here are just a few to consider:


  • large farm, user can be present at start
    -Set Computer is connected to the Internet about every to 0 days
    -Set Maintain enough work for an additional to 0 days
    -Change PrimeGrid preferences to a fast WU project such as PPS LLR
    -At Challenge start, update PrimeGrid preferences and only select AP26 project
    -After all machines have work, increase Maintain enough work for an additional
  • large farm, user NOT able to be present at start
    -Same settings as above but skip the fast WU project and go directly to ONLY AP26 project.
    -At worse, you'll only be 1 WU late on each core starting the Challenge.
  • a few computers, user can be present at start
    -Change PrimeGrid preferences and only select AP26 project
    -Set computers to "No New Tasks" for PrimeGrid
    -At Challenge Start, update computers to "Allow New Tasks"
  • a few computers, user NOT able to be present at start
    -Set Computer is connected to the Internet about every to 0 days
    -Set Maintain enough work for an additional to 0 days
    -Change PrimeGrid preferences and only select AP26 project
    -At worse, you'll only be 1 WU late on each core starting the Challenge.


NOTE: This presumes you have all other BOINC projects suspended.

Best of Luck to everyone!

Is the setting ""max to send" will be dropped to 8 tasks" for each CPU or for the host?
It the latter hosts with more than 8 CPUs and 1 GPU are hampered by this setting.

It'll just mean a 16 core box will have to connect twice to get initial work - not a major problem.
Once you have the initial work, the per-core limit will be the main limiter.

I have noticed over the past 24 hours, longer WU's being released..

several of my boxes were doing these in just over 15 min. now they are doing them in 24 min...
There are still some 15 min WU's mixed in the cache.
From 15.41 min to 23.42 min is a big increase in crunch times.

Are you increasing the lenth of these WU's? if so, is credit going to be adjusted to compensate?


further inspection of the WU's AP26_4xxxxx and AP26_3xxxxx are the shorter ones, the longer ones appear to be ap26_2xxxxxxxxx


*** DUH!! Never mind, I just checked my hosts page, and it does appear the credit has been adjusted to compensate. **

Personally, I like the longer WU's (as long as credit is adjusted) less stress on my network.

13 hours to go!!!

The witching hour is upon us. 13 hours till the start of the Winter Solstice Challenge. The pre-fires have a nice red glow, and we're expecting them to turn a deep blue once the Challenge begins. Who knows...by the end of the Challenge they may become white hot. :)

Please once again review the "Welcome" post as well as the "How to Join" post so you can be informed and make any last minute adjustments that are necessary.

A few hours before the Challenge, we begin to monitor the Meebo chat room at the bottom of the forum page. If at any time PrimeGrid becomes unresponsive, you can still access the Meebo chat room externally here: http://www.meebo.com/room/primegrid/

Before the start, the Subproject stats on the Server Status page will be disabled as will the 24 hour stats on the bottom of the front page. Also, the Top Primes Finder page will be disabled. This is all done to free up as much resources to allow the server to send and receive work.

What to expect at Challenge start

The server always gets hit hard at the beginning of the Challenge. However, a procedure that we've been using for all the Challenges this year has been very successful so far, and we hope it holds true for the final Challenge. A few hours before the start (18 December 2009 17:47 UTC) "max cache" will be dropped to 16 tasks per core. Additionally, "max to send" will be dropped to 8 tasks per core. Anyone attempting to request more will be met with "max cache" messages.

We'll load at least 500K into the buffer. At the start of the Challenge, these settings will be adjusted as necessary. However, if the past year is any indication, we'll make the first adjustment around 30 minutes post start by raising "max cache" to 32. We'll continue to increase "max cache" when the server can handle it until a full 3 days max cache is possible.

This method allows the greatest opportunity for the most clients to get work. Even if it's just 1 task for the first 10 minutes, at least the client is crunching. Past Challenges have shown that clients have a good chance to reach "max cache" before their first task is complete. We expect the same this time.

The source of the app is open source so no one holds you back to implement an ATI-version of the application. ;)

Yes, something looks weird.

First:

I thought each WU was 35 credits?

Second:

123___70________Ken_g6 - TeAm Anandtech

But I submitted 4 at once!

Probably because there are still some of the old 23.61 credit units cycling through the system (e.g., due to aborted by user, timed-out, etc.)


Edit: Okay...here's how...

212.46 = 35.41 * 6

212.48 = (23.61 * 6) + (35.41 * 2)
____________
141941*2^4299438-1 is prime!

Stat links are on the homepage, under the timer.

I see how my two questions work. waffleironhead had 2 of the old WUs somehow. Meanwhile, for some reason, two of my WUs are still pending. Huh.

Stat links are on the homepage, under the timer.

I see how my two questions work. waffleironhead had 2 of the old WUs somehow. Meanwhile, for some reason, two of my WUs are still pending. Huh.


Be lucky you only have 2...I have close to 100 already...

Will buy a new PSU for my Xeon E5405 tomorrow and put it up to help my staggering team a little bit out.

Message 19960 - Posted: 20 Dec 2009 | 5:06:44 UTC

I have 9800 GTX+ cards (8 of them). Anyway the AP26 cuda 23 app used to take 9 min to complete, but lately they've been taking 20 min. I've heard that the tasks have been doubled in size. Anyway, Today, I've seen two of them on separate machines running over an hour and then 2 hours. I aborted the tasks as they showed NO progress. On a third machine I see one past 2:17:00 but shows 88% done. I wonder if there's a reason for that, and perhaps I shouldn't abort them. Could they be finding AP26 or 25's??? Has the length been increased 10 fold?

Please advise.

How can I find out that I've discovered an AP? Everything else I can see on my projects page, but on AP26 search is only number of tasks done and the amount of cobblestones, of course.

Only AP20+ are reported in the stats.
If you only have WUs done + credit you haven't found a AP20+ up to now.
I have 700000+ credits and 29350+ WUs crunched for the AP26-subproject, that is 20-fold of your overall credit - i think you have to crunch some more AP26-WUs to find one AP20+.

OK, Now it appears they're running long enough to exceed some time limit and are aborting themselves with "Maximum elapsed time exceeded

Here's a list from my tasks pages. They are on different machines.

Hi Logan

What you have found are three arithmetic progressions of primes with 20 primes in the series. Pretty amazing stuff. The hunt is for progressions with 26 primes in the series. The occasional updates are for series of 23 and 24 primes. So while yours are good things to have they aren't the ones being written about. Keeping try tho' the next one might be the one.

BTW the English is great!

Cheers!

T

Edit: Ooopss! Sorry I just saw someone already explained. Anyway welcome again.

Only 13 hours remain!

Now's the time to start preparing for the end of the Challenge. Please remember to upload early and often. The server is going to get hit hard as the Challenge draws to an end. We will start to lower "max cache" to help with this.

Only work units issued AFTER 18 December 2009 17:47 UTC and received BEFORE 21 December 2009 17:47 UTC will be considered for credit.

For those "moving on" at the conclusion of the Challenge, we ask that you abort your WU's after the end. This helps out greatly with the clean up. However, if you have the resources, please consider completing the work in your cache before "moving on".

Good Luck to everyone as we finish these last 13 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. 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. :)

Let's forget about my issue. The challenge is effectively over and I'm reallocating my machines back to pre challenge projects. I'm not seeing any other reports of it, and at this point I'll just forget it, and avoid the losses.

I wasn't here for the start, but everything seems pretty smooth right now.

I even started up the the old PIII 1ghz :)

I had one of those going. Mine completed one every 4 hours. How did your's do? Mine would probably be faster if I had more than 300 Megs of ram.

I noticed that I have some 'ghost' WUs left from the challenge. What would you like me to do about them?

That was fun. Thanks to all especially those I strove with neck and neck and of course those who made it possible. Next time could I have some wus which generate an interesting result?

Probably I mentioned it before (but that never stops me) the challenge series has proved so successful that I think it'd be neat for future series to award points to more competitors say the first 100 teams and the first 500 participants. It'd make it more fun for more people and hence generate more interest and hence more wus processed..

"... as Tiny Tim observed, God bless Us, Every One!*"

Cheers!

What I'm amazed about is that the server kept up and only crashed immediately after the challenge when a lot of result aborts happened :)

Abort them if you feel guilty.


WUs that the project says I have in progress, but I know I don't, since I crunched my caches clear. Usually happens when the server is being hammered and sends a WU, but doesn't realize it didn't get through.

I cleared all but 5 ghosts by detaching and reattaching...just have to have the time for last 2 or 3 hosts to do the same...

that was a heckuva challenge. I've never seen so many folks or teams on a PG challenge.

I'd suggest that's down to the CUDA app.
Thanks go to Gerrit and Bryan for that.
Pete.

That was fun - and the closest of finishes for the last of the points:

29 Team-Goobee.org 113796.03 3.0
30 Guru Mountain 113796.02 1.5


Very tight indeed!



Grrrrrr. Guess who's a member of Guru Mountain? If those (any of those) damned long runninig wu's hadn't faulted out, then we'd have doubled our challenge points.

Yes, this was quite a fun challenge, My first for PG. I think I will be back next year for more of them.

What I'm amazed about is that the server kept up and only crashed immediately after the challenge when a lot of result aborts happened :)

That's what longer runtimes and probably also the inflated estimated runtimes, when running GPU and CPU tasks in parallel, do for you.
