Welcome to the Winter Solstice Challenge
The Final Challenge of the 2011 Challenge series is upon us. The Winter Solstice Challenge will be a 3 day (72 hour) celebration is being offered on PrimeGrid's most successful sieve, the PPS (Sieve) application. Come join us and warm yourself by the Solstice fires!
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 PPS (Sieve) project in your PrimeGrid preferences section. The challenge will begin 19 December 2010 05:30 UTC and end 22 December 2010 05:30 UTC. Application builds are available for the following:
- Microsoft Windows (98 or later) running on an Intel x86-compatible CPU 1.38 (ati13ati)
- Microsoft Windows (98 or later) running on an Intel x86-compatible CPU 1.39 (cuda23)
- Microsoft Windows (98 or later) running on an Intel x86-compatible CPU 1.39

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 19 December 2011 05:30 UTC and received BEFORE 22 December 2011 05:30 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 2251 cobblestones per WU.
[edit] WU increased from 6G to 9G; credit increased to 3371.
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.
Our initial 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=800K. PG 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 about 292 "classical" Fermat number factors known. Current primes found in PPS definitely make it into the Top 5000 Primes database.
Once the 800K goal is reached, we may head to 1M before turning our focus to smaller k values and higher n values. For example, k<300 complete to n=2M, k<600 complete to n=1.5M and so on.
For more information about "Proth" primes, please visit these links:
About Proth Search
The Proth Search project was established in 1998 by Ray Ballinger and Wilfrid Keller to coordinate a distributed effort to find Proth primes (primes of the form k*2^n+1) for k < 300. Ray was interested in finding primes while Wilfrid was interested in finding divisors of Fermat number. Since that time it has expanded to include k < 1200. Mark Rodenkirch (aka rogue) has been helping Ray keep the website up to date for the past few years.
Early in 2008, PrimeGrid and Proth Search teamed up to provide a software managed distributed effort to the search. Although it might appear that PrimeGrid is duplicating some of the Proth Search effort by re-doing some ranges, few ranges on Proth Search were ever double-checked. This has resulted in PrimeGrid finding primes that were missed by previous searchers. By the end of 2008, all new primes found by PrimeGrid 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. For 2010, we hope to complete our reservation to 800K and extend it to 1M.
PrimeGrid intends to continue the search indefinitely for Proth primes.
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 PPS sieve is Geoff Reynolds'/Ken Brazier's tpsieve 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.

Sample WU times
Copied from the GPU Performance at PrimeGrid - October 2011 Update thread. Special thanks to Scott Brown for compiling these times.
I thought it would be informative to have a fairly comprehensive updated measure of how GPUs perform at PG. The below table was created by examining the PPS Sieve times in October 2011 for machines from the first 2000 of the top computers list and supplemented with various GPUs that are mine/I have access to. For those GPUs from the first 2000 of the top computers list, the times were taken from the highest ranked computer with a single GPU install that had completed PPS Sieve units. Thus, it is likely that many (if not most cards) have factory or user overclocking. Thus, these times in many cases represent the best possible times for these cards. Obviously, your times may vary somewhat based on 1) your shader clock/overclock, 2) other loads on the GPU and CPU, 3) whether the GPU is a single or multiple GPU install and the corresponding matched CPU, and 4) other things not herein mentioned. Where needed/possible, I have placed appropriate notes in the table (e.g., when it is one of my GPUs and I know the overclock). Anyone with a GPU not listed is welcome to add their data...Indeed, individuals with dual-GPU NVidia devices (GTX 590, GTX 295, 9800 GX2) are especially encouraged to add data as such GPUs are more difficult to verify in the top computers list since they are always listed as being multiple GPU systems.

From this list, the advantage of fermi-based cards should be clear. Likewise, the ATI cards are clearly hampered by the need to use OpenCL rather than native CAL instructions. Sorry that the list for ATI could not be more specific, but BOINC does not report anything more specific than the ATI families. You can probably safely assume that the times are for the fastest cards in those families.
One final note to remember regarding this list and card performance at PG. Currently there are two GPU applications in standard use at PG: PPS Sieve and CW Sieve. While these are similar in that they are Sieves and are based on the same algorithm (at least as I recall what Ken said about writing them), performance rankings on these may/will not be identical. I have observed some subtle differences in the cards I own in how they rank against one another in the CW sieve vs. what is in the table above. This is likely due to the drastically different ranges being sieved at the moment (I believe that PPS Sieve is in full on 32-bit mode while CW Sieve may still be at a 24-bit level).
Additionally, LLR Cuda is being tested. This new application requires the use of double-precision calculations. That means that many of the cards above will simply not work with that application. Also, the current advantage of the best GTX 5xx and 4xx series over Tesla and Quadro cards (which is due entirely to much higher stock shader clocks) will likely disappear and be reversed since the Tesla and (I believe newer) Quadro cards have better DP capabilities (i.e., fermi-based GeForce cards have 1/4 DP power compared to their single-precision capabilities while DP and SP power on Tesla cards is the same).

You are a little bit too optimistic. DP is only half of SP (like seen on all AMD/Intel cpus) or nVidia has slowed the SP capabilities. Check yourself at http://en.wikipedia.org/wiki/Nvidia_Tesla.
Maybe the coming Kempler brings improvements in this direction...

In an effort to provide the best opportunity for a "problem free" Challenge, we have increased the sieve range from 6G's to 9G's. Credit also increased from 2251 to 3371. Expect a 10 minute PPS (Sieve) task to now take 15 minutes, 30 minutes to take 45 minutes, 1 hr to take 1.5 hrs and so on.
We also plan to switch PPS (LLR) to k=5,7 for n=3M to 4M as soon as the current range reaches n=775k. This has a two-fold effect of lower DB size as well as decreasing the number WU requests. Both will benefit a better Challenge.

Sounds good from a rat point of view. Huey is planning on killing and eating a couple of cows on his own by all counts. And there are another 20 of us.

Still 9.2 is not a bad time. Just glad to see you moo'ers are still around. It's almost like you were so winded after the last challenge you had to go lay down for bit :)
The horde is looking forward to another round... have to dust off my 9800 and see if it will even run a pps.

We might not have much big GPU-cows, so a top 10 place like in the CPU challenges will be out of the question, but giving up is not in our nature, so you can count on a nice battle.
Ofcourse our intel is ongoing, so we noticed the rats have increased in force, making it an even more challenging fight.
I think it will be closer than the last challenge.

Yeah...I know. I was typing rather hurriedly back in Oct. when putting that together and meant that to say "more similar" rather than "the same". When I realized the gaff, I was already beyond the edit time window.

AJ, it will be fun no matter what. As I recall the cows have pulled it out the last 2 times so I have no doubt this will be another close race. Oh, I thought all you cows were big :)

Ofcourse I am trying to make the cows the underdog ;)
But I'm sure we'll be giving you a hell of a fight and be victorious at the end.
By the way, I forgot we do have a few more big GPU-cows like Amberjr. So I hope they will join the challenge.

Sample WU times
Anyone with a GPU not listed is welcome to add their data...Indeed, individuals with dual-GPU NVidia devices (GTX 590, GTX 295, 9800 GX2) are especially encouraged to add data as such GPUs are more difficult to verify in the top computers list since they are always listed as being multiple GPU systems.
My stock GTX 590 complete a WU in about 12.5 min

We are certainly looking forward to it. We don't aim to lose but if we do it might as well be to the herd. So good luck to you.
We are starting to think about a mod of the Agg's Birthday Challenge in April 2012 which we hope you will take up. A PM to any of our more active people will get you details.

It's about time someone came up with a cook book that includes the horde. I mean for years and years there's been nothing but cook books and recipes and formulas and ideas on how to serve up a cow.

Hi
Yesterday PPS sieve took 527secs Run Time - 69 CPU time on a OC GTX 580 for 3371credits.
Today same WUs take 805secs Run Time - 70 CPU time on the same OC GTX 580 for the same 3371 credits.
a stock GTX 580 takes 15 mins.
Perhaps there should be a NOTE on the front page of the challenge site page telling everyone about the 2 changes of credits and run times.
Cheers
Ross*

Hi
Yes thats were I first viewed it. Does everyone Know? does everyone read message logs?
with in the last 30 mins the older runtimes are back.
10mins stock 580
8-40 for OC 580
same 3371 credits
So what changed?

A teammate at UK BOINC is looking to participate using cpu only.
Anyone have an idea how long a WU will take on cpu?
I don't want to put him off but I think it would be fair to let him know what he's in for.
Thanks,
Peter

I was trying to get my AMD GPU up on Linux the last few days, and once I got BOINC to recognize it, I apparently still didn't have the APP drivers, so it errored out, and on one of them it fell over to my CPU to analyze. I didn't run it all the way through, but on my Athlon 64 6000+ running 64 bit Ubuntu, the calculator was estimating 24 hours to finish it.
Probably not the most reliable answer, but at least it's one data point.

You can check the average cpu runtime on your settings page. Last I looked (this morning) the average was about 178 hours, i.e. 7.4 days.
Now I know my i5 2500k is about twice as fast at stockspeed, giving me a time of 3.7 days. Which is still over the limit unfortunately, since the challenge only lasts 3 days.

Anywhere from a long time to a really long time, depending on whether he's running a 64 bit OS and how old his CPU is.
Last time I can remember comparing them, my GPU could do these 40 times faster than my CPU. With the recent WU size increase, I expect the WU to take about 35 minutes on the GPU, so on the CPU I would guestimate 20 hours. That's a 2.4 GHz Core2Quad with a 64 bit OS, so adjust your own estimates accordingly based upon your hardware.

Proth Prime Search (Sieve)
The Winter Solstice Challenge project
Supported platforms:
Windows: 32bit, 64bit (+CUDA23, AMD OpenCL1)
Linux: 32bit, 64bit (+CUDA23, AMD OpenCL1)
Mac: 32bit, 64bit (+CUDA32, AMD OpenCL1 - 64 bit only)
1 Requires AMD Accelerated Parallel Processing (APP) drivers.If APP driver not available for your card, then the ATI Stream SDK is needed.
Recent average CPU time: 2:36:30
It should be noted that this average is a mixture of CPU and GPU, and is therefore utterly worthless.
20 hours is probably a good "median" estimate right now. My Core2 CPU is getting a little old in the tooth, but a lot of newer CPUs will be using hyperthreading so their CPU times will actually be higher than the older Core2 chips. Probably only the faster Sandy Bridge CPUs will beat the Core2s (and the similar-speed Phenom IIs) with hyperthreading on.
So figure on about 20 hours for my CPU. If yours is older, it will take longer. If you're using hyperthreading, it will probably take longer. If you have a newer chip and forgoe hyperthreading, it will take less time.
Also, adjust the run times by as much as 50% in either direction, depending on clock frequency. Mine's kind of in the middle, near the bottom of desktop clocks, but higher than most laptops.
So, all in all, 20 hours aught to be a good median.
All of this, of course, is theoretical. Some hard data on CPU run times would be nice.

So I went and tested it.
I started one of these on the following system:
Intel Core2Quad Q6600, 2.4 GHz. Windows 7 Professional, 64 bit.
It took 2:59 of CPU time to get to 0.200% complete, which yields a run time for a complete WU of just about exactly 25 hours of CPU time. Your actual runtime will vary by how much system overhead you have, and, of course, what your hardware is.
So there's your benchmark if you want to know how long this will take on a CPU.

AMD X6 1100T a @ stock clock - about 14.75 hours. (but that is per core...divide that by 6 cores and you get performance similar to a GT220 card with 48 shaders over that same time period, though the power consumption is obviously not even close).

As mentioned in another thread, I did quickly test one unit on CPU. I calculated a time to complete of 15 hours on stock i7-2600k which was running 4 PPS LLR tasks at the same time with HT on (64 bit OS). Personally I wont be running CPU sieve. |

Great to hear that you finally got boinc to recognize your GPU and for the GPU to crunch under Linux.

Yup. Thanks a lot for the help. The link to the other forum that talked about giving BOINC access to the Catalyst Drivers was a big help. And I think someone else in there mentioned needing to download and install the APP/SDK drivers directly from AMD's website, so I had to do that too. I've been meaning to reply to one of the original threads with how I fixed it, but haven't had the time.
Thanks again. |

FYI...normally the place to park your CPU cores before a Challenge is the PPS (LLR) project. However, because we have loaded high n ranges this time to help lower the size of the DB and the stress on the server, SGS (LLR) is a better place to park.
Not that this will have a "huge" impact as this is mostly a GPU dominate Challenge. Best of Luck to everyone!

Hi, While I scrolling this thread, I noticed wolfemancs' question about ATI GPUs on Ubuntu linux. Although, I haven't tried an ATI GPU with primegrid on Ubuntu Linux yet, I plan to someday. In preparation, I found instructions on this Web site: http://elect86.wordpress.com/2010/02/16/howto-ati-cal-on-karmic-64-bit-with-boinc-collatz-project/ The info is a little out of date, and I haven't tried it myself, but if your willing to try it, then please let me know if how it worked.

How to Join the Challenge
To participate in the Challenge, please select only the Proth Prime Search (Sieve) project in your PrimeGrid preferences section. Also, set "Send work from any subproject if selected projects have no work" to no to guarantee that no other work will be sent. The Challenge will begin 19 December 2011 05:30 UTC and end 22 December 05:30 UTC. Application builds are available for the following:
- Microsoft Windows (98 or later) running on an Intel x86-compatible CPU 1.38 (ati13ati)
- Microsoft Windows (98 or later) running on an Intel x86-compatible CPU 1.39 (cuda23)
- Microsoft Windows (98 or later) running on an Intel x86-compatible CPU 1.39
- Microsoft Windows running on an AMD x86_64 or Intel EM64T CPU 1.39
- Linux running on an Intel x86-compatible CPU 1.39 (ati13ati)
- Linux running on an Intel x86-compatible CPU 1.39 (cuda23)
- Linux running on an Intel x86-compatible CPU 1.39
- Linux running on an AMD x86_64 or Intel EM64T CPU 1.39 (ati13ati)
- Linux running on an AMD x86_64 or Intel EM64T CPU 1.39 (cuda23)
- Linux running on an AMD x86_64 or Intel EM64T CPU 1.39
- Mac OS 10.4 or later running on Intel 1.39
- Mac OS 10.4 or later running on Intel 1.39 (cuda32)
- Mac OS 10.5+ running on an Intel 64-bit CPU 1.39
- Mac OS 10.5+ running on an Intel 64-bit CPU 1.39 (cuda32)
Time zone converter:
The servers are located in the Northern Hemisphere; therefore, we'll observe winter. However, the Southern Hemisphere will be experiencing the Summer Solstice.
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 19 December 2011 05:30 UTC and received BEFORE 22 December 2011 05:30 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 2251 cobblestones per WU.
[edit] WU increased from 6G to 9G; credit increased to 3371.
What to expect at Challenge start
The server always gets hit hard at the beginning of the Challenge. A few hours before the start (19 December 2011 05:30 UTC) "max cache" will be dropped. Additionally, "max to send" will be dropped. Anyone attempting to request more will be met with "max cache" messages.
We'll raise the front page buffer before the start of the Challenge. These settings will be adjusted as necessary. Afterwards, as conditions allow, we'll raise "max cache". We'll continue to increase "max cache" when the server can handle it.
This method allows the greatest opportunity for the most clients to get work. Even if it's just 1 task for the first few minutes, at least the client is crunching. Past Challenges have shown that clients have an excellent chance to reach "max cache" before their first task is complete. We expect the same this time.
____________

A couple of quick questions:
- During the challenge, will there still be recycled 6G units in the pipeline to issue? If so, will they disproportionately benefit the (lucky) recipients, or will the scoring account for that?
- Will the "fresh" WU size revert to the smaller 6G size after the challenge? Or stay at 9G?
Thanks, and we're looking forward to the challenge!

I've got my 1100T OC to 4.0Ghz and ran some test WUs and they all were in the 11:55hrs - 12:05hrs range and my Phenom II 970 OC to 4.1Ghz WUs were 12:20hrs - 12:35hrs. I ran 2 at a time first then 1 while all other cores were crunching TRP sieves on the 1100T and LLR WUs on the 970.

as of 12:30 EST in Ohio, USA, yep!
Only one problem...when my rig polled for WUs on PPS, I have my system set for 3 days, and I got TWO!!! For some reason, BOINC says it's going to take over 31 hrs on my GPU to do ONE WU.
I'm running an ATI Radeon HD 4700/4800 w/2Gb on an Intel Core2 Quad Q8400 w/8GB RAM. Not sure why they're that high, but the one that's working is going down pretty fast.
Good luck everyone!

Hi All,
Is there something i'm missing? Ive been cruching for 55min's & have multiple completes, still my name isn't up yet. I only have PPS Sieve for CPU&GPU & have update pref's again just to make sure all is right. Any Help?? I'm roaring to crunch.. |

If anyone has crunched any PPS LLRs OR sieves since the sudden large increase in run times, it has probably screwed with Boincs WU estimation numbers. That's a likely reason the high initial long estimation on Primegrid WUs now. You can always reset the Duration Correction Factor (DCF) to 1.000000 in the client_state.xml file located in your C:\ProgramData\BOINC folder for Vista & Win 7 using ONLY notepad. It's in the first group of data at the beginning of the Primegid section for those who don't already know. You need to stop BOINC first and restart afterwards.

Did you make sure to only crunch wu's that were downloaded after the challenge started? Anything in your cache prior to the start time won't count. |

Most of the Wu's you already completed were downloaded before the Challenge began, so they won't count towards the Challenge ...

It's in the first group of data at the beginning of the Primegid section for those who don't already know. You need to stop BOINC first and restart afterwards.

I even hat to reduce the DCF to 0.410231 (1/4 of original) to get a nearly exact " Time left" information.

Hi all,
And thanks for the replies, I should have read the fine print. Oh well you can be sure that won't happen again. That's around 20,000 points down the drain :(

Based on the early stats... how many out there have GPU farms? I didn't think I'd do too badly but this one I don't think I'll come near a top 100 finish and break my streak for the challenge year... |

I have 7 GPU's -- and I would be happy with a top 100 place the way this is going

You will make it in the Top100 DoES, no worries.
It is amazing how much power there is at this challenge. During the last CW-sieve challenge I finished on place 73. Now I am not even close to the top100 with the same hardware.

There certainly are some big guns out there-- 7.37pm here so I have been following it from the start --- I have been bouncing along between 50th to 60th place by reporting immediately --- when the big work caches report in it will be interesting
Good luck man!!!

I wonder if anyone decided it was worth it to rent some computers for the challenge? For about $18/day you can rent a dual-Tesla server (which also has a lot of CPU cores) if you use Amazon's spot pricing. It's probably more useful for something that requires double precision, like llrCUDA or GeneferCUDA, but it would still be interesting to see how fast an M2050 is. (And, no, I don't see anything wrong with renting computers for the challenge. If you got the bucks, it doesn't matter if you build, buy, or rent.)
Corrolary: I wonder if Amazon's spot prices for GPU-cluster machines will go up for these three days?
I don't think I've ever done better than about 250th place or so. I was so thrilled when we had the first GPU challenge! I figured that was my chance to finally break into the top 100! Nope! Didn't do any better; PrimeGrid's crunchers have an amazing amount of computer power available. You guys (and girls) are fantastic.

A couple of quick questions:
- During the challenge, will there still be recycled 6G units in the pipeline to issue? If so, will they disproportionately benefit the (lucky) recipients, or will the scoring account for that?
- Will the "fresh" WU size revert to the smaller 6G size after the challenge? Or stay at 9G?
Thanks, and we're looking forward to the challenge!

There are still 6G WUs in the pipeline. The credits (and the challenge points!) for the 6G WUs are the same as for the 9G WUs...

160-ish and dropping... just hope my no-score here wont drop me too much in the overall individual rankings.
I thought I had a fighting chance running a 450, 560 and 6850. Guess not! |

Ha at least you will get there. I'm stuck down around 300 - been a long time since I was that low but will have to get to used to it.

Still missing two of our biggest cows :(
They haven't responded to our calls. Too bad, but we can't complain about the output.
Also Amberjr had a BSOD on his rig with 3xGTX570 which luckily only cost about an hour of output.
I must say the rats are also doing great at the moment with position 20.
Keep it up!

huuh, forget to clear the cache at the beginning of the challenge, so several hours are lost till the first wu's blow up.
Now still slowly come upwards a bit.

If anyone has crunched any PPS LLRs OR sieves since the sudden large increase in run times, it has probably screwed with Boincs WU estimation numbers. That's a likely reason the high initial long estimation on Primegrid WUs now. You can always reset the Duration Correction Factor (DCF) to 1.000000 in the client_state.xml file located in your C:\ProgramData\BOINC folder for Vista & Win 7 using ONLY notepad. It's in the first group of data at the beginning of the Primegid section for those who don't already know. You need to stop BOINC first and restart afterwards.

Thanks for the info. I'm sure there's still a little "indegestion" on my rig that's causing a small slowdown, but once I got the change made, I had a bunch of WUs come in for PG, and the other three that I have on CPU.
Again, great fix! Look forward to seeing you in the *s...:)

I guess you are right ;) I've only noticed it because the first WU on the slower card finished 37 seconds ealier than the first WU on the faster card.
Now back to browsing the latest nouveau driver commits ("initial engine reclocking")... a linux clock setting tool for Fermis would be nice...

I wonder some day if Boinc will ever address the runtime issue --
I am looking at my i7 920 cores crunching sieves --- all cores showing 96% complete -- 30.5hrs elapsed --1+ hours remaining -- deadline 25/12/2011 ---- all still running High Priority!! -- today is the 20th as far as I know
I don't mind crazy runtimes at the start --- but it ain't rocket science to work it out at 96% complete
Now I have an old Pentium D that has reported 2 sieve WU in 28hrs (bless its ancient heart) --- now it is running 1 core at a time because 1 WU is high proirity -- it does 1 core then the other core --- 28hrs--- hello!!????

October : 6G WUs
Now: 9G WUs
BTW: "New" drivers are not always the best...
Ok, 116*1.5=4h20m? ;) The "green" ist in OC as fast than the normal GT but needs no powercables.
BTW: would be nice to update the "how-to" from "use the latest driver" to "use THIS driver for your card". I guess I'm not the only one who use "old" hardware for science instead of dropping it on a depony in the "3rd World", *hmmm?*

Older nVidia cards (technology not when bought) tend to like 266.58 or 258.xx driver versions but not always. Depends on your system.

You might want to read that full post rather than just the time for you card model:
For those GPUs from the first 2000 of the top computers list, the times were taken from the highest ranked computer with a single GPU install that had completed PPS Sieve units. Thus, it is likely that many (if not most cards) have factory or user overclocking.
Thus, the 9600GT listed is probably not a "normal" model at standard clocks.
Also, even the 6G work units now would be a bit longer than those from October given how the sieve ranges progress.

Now now -- be nice -- we were 24th last time I looked -- we had a fair idea we were going to cop a flogging as we don't have that many GPU's as a team.
But we are doing the best we can given the heavyweight GPU crunchers out there.
Good luck to all!!!

Yes I think I've been stepped on several times. I just can't get my poor old gpu running any faster. I do have team mates that are motoring right along. No excuses being made however :)
I do believe however that because of Tim's initial challenge to the cows about 3 challenges ago you have rounded up your way ward strays and have come together just to beat us. That's quite a compliment to us :)

Sorry, it might have been me who stepped on you ;)
I must agree that we have rounded up some more cows to beat you. But I must also say that place 20 is about normal for the cows, that is the place we are standing in the general ranking on PG, so we are just a little bit higher ranked in the challenge.
Anyway, if challenged the cows always respond! As do the rats, a really big improvement the last few challenges, kudos!

Yes - its a tight battle at every level -- I am locked in a battle for 76th place with a honourable gentleman from China by the name of Mr eruda -- we dead heat about every 45 minutes -- as I scroll up the page during the day there are sometimes deadheats up as far as 15th place
I think it will be a very close finish

Well make a note in your diary (or should that be dairy?) about Agg's Birthday Challenge on 4 April 2012. We are hoping to widen the appeal and Holland gets a special mention in the idea.
I'll PM you about it (maybe you've seen the discussion on our board anyway).

By making the WU's bigger you have made it so that only the faster PC's can join the fun!
So far I have been able to U/L just 2 WU's and may get to U/L 2 more before the end of the race.
If this is what you are going to do from now on I will not be in your short races.

For the most part, PPS (and GCW) sieving is a GPU-only activity. Comparitively speaking, only a small percentage of those sieves is done by CPUs anymore.
With GPUs getting faster -- and more common -- every day, PrimeGrid had a real concern that the load on the server from the challenge would bring everything to a grinding halt. It's happened before when challenges with short WUs were run. While you might be struggling to complete these WUs, please understand that the faster computers were completing WU's in 10 minutes or less per GPU, and many computers have multiple GPUs.
Therefore, the decision was made to increase the WU duration by 50%.
The problem you experienced had little to do with the length of the challenge, and everything to do with using a CPU in a challenge dominated by GPUs. (Think of the classic quote, "Never bring a knife to a gunfight.")
On the other hand, if there's a one-day challenge on the SGS project, you'll have no difficulty since the WUs are very short.

The Solstice is soon upon us. Bundle up tight as it's going to be a long Winter's night. 12 hours remain in the Challenge. Time to round up all those factors, combine them into one HUGE yule log, and toss it into the fire.
The Winter Solstice arrives at 05:30 UTC 22 December 2011. Get your factors in by then. :)
--------------------------------------------------
Year End Goals
As this is a sieve Challenge, there is no "clean-up" period. In lieu of the typical "clean-up", we warmly invite everyone over to the PPS (LLR) application to help us reach our year end goals. The March to the Solstice has done a wonderful job pushing us towards those goals, but we're going to need a lot of help to reach them by end of day 31 December 2011.
To participate, please select Proth Prime Search (LLR) in your PrimeGrid preferences page. Available for CPU only.
Proth Prime Search Update
k=3 to 25M is ongoing in the 321 Prime Search (trailing edge n=7673589; leading edge n=8192966)
k=5 to 5M ongoing (trailing edge n=3002019; leading edge n=4322187)
k=7 to 5M ongoing (trailing edge n=3000214; leading edge n=4322132)
k=9 to 3M (currently at n=3M)
10<k<32 to 2.5M (currently at n=2.5M)
32<k<100 to 2M (currently at n=2M)
100<k<500 to 1.5M ongoing (trailing edge n=1187833; leading edge n=1.2M)
500<k<1200 to 1.3M (currently at n=1.3M)
1200<k<4000 to 800K ongoing (trailing edge n=759855; leading edge n=775k)
4000<k<10000 to 725K (currently at n=725k)
Green is completed goal. :)
--------------------------------------------------
World Record Sieving
If sieving is more of your "cup of tea", then please see the manual GFN sieve. PrimeGrid is currently preparing for a World Record largest prime search early next year and currently needs plenty of help on preparing the test field.
For more details, please see: GFN Sieve Information
NOTE: This is a manual sieve in the Project Staging Area. Available natively only for Windows 64 bit (however, can be run within VM). PSA credit is available.

The bigger problem was the switch to such larger PPS LLR work. Many crunchers were attached to that project in the "march to the solstice" work. Switching to such drastically different sized work screwed up the DCF's on machines badly (a BOINC problem rather than a PG issue...though a long-time, well-known one that could have been anticipated). For me (and I imagine several others with remote machines), it means that many of my CPU cores (even some quite fast ones) are churning through that backlogged work downloaded due to the problem DCF and not even asking for PPS Sieve work (and before some one asks, yes, I switched to SGS more than 24 hours before the challenge...that made no difference given the DCF issue).
In the future, I hope that drastic within-project work lengths can be adjusted in more modest manner than we have just experienced, especially just before a challenge occurs.

You can say however that this challenge went very smoothly and it has to be due in part to the changes they made to both the pps projects. I agree there were down sides to lengthening the pps llrs and some in lengthening the sieves but I have yet to see one person post issues getting work during the entire challenge and it sure hasn't be full of grumblings like we had during the pps llr challenge earlier. And, it's just a 3 day challenge.
I say to the admins, it was a great challenge ! Thank you.
ps - please ensure the double points are posted to the members of AtP before you finalize the results :)

"Modest manner" is relative. However, we'll do our best to make better, more accurate changes. :)
Two things happened to cause this DCF issue. First, the advice to use SGS (LLR) instead of PPS (LLR) to park cores before the Challenge was offered too late. Second, we failed to adjust the "estimated task size". It was an oversight on our part and we apologize. By the time the error was realized, it was too late. Much work had already gone out.
We also implemented an additional "stop gap" measure, max CPU tasks was lowered to 25.
As Rick mentions, a side effect of our intentions (although errored) was a smooth Challenge. It's quite remarkable to see the server status graphs look so...low, especially during a Challenge. Thank you to everyone for participating.

Well based on the reply I see that PG is going toward a GPU only project. So until I have the money to buy a PC with a GPU that works with PG I guess I won't be running PG anymore!

Only the sieves PPS and Cullen/Woodall are ready for GPU. PPS-LLR on CUDA is in development but will never be a subproject for all Cuda-cards. You need a DP-capable GPU and IMO at least a GTX460. All older GPU will lose every comparison in performance and computation time against a typical CPU.

Although PG is pursuing a more efficient process to find primes, it is far from a GPU only project. The following projects are available to the CPU at PG:
BOINC
321 Prime Search (LLR)
Cullen Prime Search (LLR)
Prime Sierpinski Problem (LLR)
Proth Prime Search (LLR)
Seventeen or Bust (LLR)
Sophie Germain Prime Search (LLR)
The Riesel Problem (LLR)
Woodall Prime Search (LLR)
Cullen/Woodall (Sieve)
Proth Prime Search (Sieve)
The Riesel Problem (Sieve)
PSA PRPNet
Proth Prime Search (LLR)
Generalized Cullen/Woodall Prime Search (LLR)
Sophie Germain Prime Search (LLR)
Primorial Prime Search (pfgw)
Factorial Prime Search (pfgw)
Generalized Fermat Number Prime Search (genefer family)
27121 Prime Search (LLR)
extended Sierpinski Problem (LLR)
Sierpinski/Riesel Base 5 Project (LLR)
MEGA Prime Search (LLR)
PSA Sieve
Primorial Prime Search (fpsieve)
Factorial Prime Search (fpsieve)
Generalized Fermat Number Prime Search (AthGfn64)
Sierpinski/Riesel Base 5 Project (sr5sieve) The following projects are available to the GPU:
BOINC
Cullen/Woodall (Sieve)
Proth Prime Search (Sieve)
PSA PRPNet
Generalized Fermat Number Prime Search (genefer family) preferred as a GPU only project for N>=262144 but available to the CPU.
PSA Sieve
Proth Prime Search (tpsieve) preferred as a GPU only project but available to CPU. As can be seen, there are far more projects available to the CPU than to the GPU. Also, as Ronald points out, the CPU will continue to be superior to the GPU in most cases doing LLR. It will take some major breakthroughs to the GPU LLR code to even compete with the CPU. And in the end, there will still be some CPU only projects. :)

The results are Final!
The Winter Solstice is here!!! The yule log, filled with factors, is making for a very bright night. This has been a very successful Challenge not only for PrimeGrid but also for the entire Riesel prime search community (benefactors of the k*2^n-1 that's also sieved). Once again, a new single day record was set during the final Challenge of the year. A hearty thanks and a warm appreciation for all those involved.
PrimeGrid's overall (Challenge + regular work) daily record was set with over 432M cobblestones for a 24 hour period. Congratulations to everyone...this is another incredible accomplishment.
Over 2.86P of sieve work was crunched in ~318K tasks resulting in just over 1B cobblestones awarded. The PPS (Sieve) reached an incomplete depth of over p=94P!!! As a reminder, the sieve is 4<k<10000 and 3M<n<6M for k*2^n+1 and k*2^n-1. This is again a continuing legacy for tpsieve* and Ken Brazier's port of it to the GPU. (*originally developed by Geoff Reynolds in collaboration with Ken Brazier)
385 teams and 2776 individuals participated in the Challenge. Congratulations to Sicituradastra. as the top team and STE\/E as the top individual. Remember, the top 100 individual and top 50 team places earn points for this Challenge. NOTE: For those paying attention, these are the same two winners of last year's Winter Solstice Challenge. :)
This concludes PrimeGrid's 2011 Challenge Series. Overall final results will be posted within a couple of days.
Thank you again to everyone. We appreciate your participation and hope you had fun! We wish you a Happy Holidays and hope to see you next year!

Year End Goals
As this is a sieve Challenge, there is no "clean-up" period. In lieu of the typical "clean-up", we warmly invite everyone over to the PPS (LLR) application to help us reach our year end goals. The March to the Solstice has done a wonderful job pushing us towards those goals, but we're going to need a lot of help to reach them by end of day 31 December 2011.
To participate, please select Proth Prime Search (LLR) in your PrimeGrid preferences page. Available for CPU only.
Proth Prime Search Update
k=3 to 25M is ongoing in the 321 Prime Search (trailing edge n=7673589; leading edge n=8192966)
k=5 to 5M ongoing (trailing edge n=3002019; leading edge n=4322187)
k=7 to 5M ongoing (trailing edge n=3000214; leading edge n=4322132)
k=9 to 3M (currently at n=3M)
10<k<32 to 2.5M (currently at n=2.5M)
32<k<100 to 2M (currently at n=2M)
100<k<500 to 1.5M ongoing (trailing edge n=1187833; leading edge n=1.2M)
500<k<1200 to 1.3M (currently at n=1.3M)
1200<k<4000 to 800K ongoing (trailing edge n=759855; leading edge n=775k)
4000<k<10000 to 725K (currently at n=725k)
Green is completed goal. :)
===================================================
World Record Sieving
If sieving is more your "cup of tea", then please see the manual GFN sieve. PrimeGrid is currently preparing for a World Record largest prime search early next year and currently needs plenty of help on preparing the test field.
For more details, please see: GFN Sieve Information
NOTE: This is a manual sieve in the Project Staging Area. Available natively only for Windows 64 bit (however, can be run within VM). PSA credit is available.

To put the amount of crunching in perspective, I was using a decent GPU -- but only one -- and finished around position 550.

Well done (although you do not seem to agree). I am using just about the worst GPU that can do PG, I was not actually entering the challenge, just plodding away to my gold, and I came in at 2269 !!

GTX 295 (2 GPUs on board), GTX 460, (2)-HD5830 on different boxes, and a lowly HD4850. All overclocked to the hilt. Got the 460 down to 24 mins and the 5830s down to 43 mins. Was at 54 mins for first 3/4 then opened up a core with the new 12.1 preview drivers and CPU went from 30%-32% to 42%-44% and thus the GPUs went 11 mins faster. Could've finished close to 30 more WUs on those two. That along with time lost from a few driver crashes and system crashes I lost out on 55 or so Wus but that would have only moved me up 3-4 spots from my 112 place finish.
So much POWER in this challenge. See you at the next.
And Happy Holidays to all.

Will the WUs stay the same size now or shrink again?
I guess it's easier to leave them as they are as credit adjustment would be problematical again.

I suppose you understood that "I yor project WU comput" is a phrase in broken English "I was computing WUs in your project".
Actually "I yor project WU comput" is a loan translation of phrase in broken Russian "Я твой проэкт ВЮ щитал".
"Я твой проэкт ВЮ щитал" in itself is a modified form of wide-known in ru-net mem "Я твой дом труба качал" (something like "I yor house, shaft swinged" [I was swinging the shaft of your house]) which in turn is a way of expressing extreme dissatisfaction with the opponent in a conversation.
They say the original phrase was «Я твой дом труба шатал, мой сабак твой ног кусал. Ще смотрищ, щас милисия пазаву, мигом апщага вылетишь. Будишь свой аул щай пищенька макать» - «I was swinging the shaft of your house, my dog was biting your lag. See, 'll call the police, you'll leave the bursa in a jiff, you'll come back to your aul to dip cookies into tea».

Very nice breakdown list!
Could we get this list in a place where everyone can find it easily. Like sticky it somewhere here in the forums? I think this is the first time I've seen a list like this explaining everything so simply. I would like to refer back to it from time to time when telling others about PG.

;-) Congrats to Ukraine with their 2nd place in the 2011 PG challenge series!
and to Seti.Germany for the #3. in 2011!
Its probably my duty to add this then.. ;-)
Congratulations to Sicituradastra and the *`s with the #1 in 2011! ;-)
and also for the win in this last challenge of the year. You have
done such a fantastic job - and I cant find superlatives that gives
you credit enough. ;-))
To be the Coconut-bossessness of this little star-team is a blessing. ;-))
I`m away for the christmas/new year holiday, so sadly enough I`ve not
been able to follow it as i use to.. When it comes to PrimeGrid challenges
I`m just like a kid. I think its great fun! ;-)
Thanx to everyone who has been doing these challenges during the year -
The more the merrier.. ;-) Individual congrats will follow when the official
standings are ready. - but grats to Ste\/e, Ross* and WirelessDude for the
individual top 3 positions
and to Seti.USA and Seti.Germany for #2 and #3 team placement in the Winter Soltice Challenge.
Happy New Year greetings to everyone!
