Welcome to the Winter Solstice Challenge
The Final Challenge of the 2017 Challenge series is upon us. The Winter Solstice Challenge will be a 3 day (72 hour) celebration on account of the winter solstice. The challenge is being offered on PrimeGrid's most successful sieve, the Proth Prime Search (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 18 December 2017 16:28 UTC and end 21 December 2017 16:28 UTC. Application builds are available for the following:
- Microsoft Windows (98 or later) running on an Intel x86-compatible CPU 1.41 (openclatiPPSsieve)
- Microsoft Windows (98 or later) running on an Intel x86-compatible CPU 1.39 (cudaPPSsieve)
- Microsoft Windows (98 or later) running on an Intel x86-compatible CPU 1.39 (cpuPPSsieve)
- Microsoft Windows running on an AMD x86_64 or Intel EM64T CPU 1.39 (cpuPPSsieve)
- Linux running on an Intel x86-compatible CPU 1.41 (openclatiPPSsieve)
- Linux running on an Intel x86-compatible CPU 1.39 (cudaPPSsieve)
- Linux running on an Intel x86-compatible CPU 1.39 (cpuPPSsieve)
- Linux running on an AMD x86_64 or Intel EM64T CPU 1.41 (openclatiPPSsieve)
- Linux running on an AMD x86_64 or Intel EM64T CPU 1.39 (cudaPPSsieve)
- Linux running on an AMD x86_64 or Intel EM64T CPU 1.39 (cpuPPSsieve)
- Mac OS 10.4 or later running on Intel 1.39 (cpuPPSsieve)
- Mac OS 10.4 or later running on Intel 1.39 (cudaPPSsieve)
- Mac OS 10.5+ running on an Intel 64-bit CPU 1.39 (cpuPPSsieve)
- Mac OS 10.5+ running on an Intel 64-bit CPU 1.39 (cudaPPSsieve)
- Mac OS 10.5+ running on an Intel 64-bit CPU 1.49 (openclatiPPSsieve)
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 2017 16:28 UTC and received BEFORE 21 December 2017 16:28 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 3371 cobblestones per WU.
At the Conclusion of the Challenge
We would prefer users "moving on" to finish those tasks they have downloaded, if not then please ABORT the WU's instead of DETACHING, RESETTING, or PAUSING.
ABORTING WU's allows them to be recycled immediately; thus a much faster "clean up" to the end of an LLR Challenge. DETACHING, RESETTING, and PAUSING WU's causes them to remain in limbo until they EXPIRE. Therefore, we must wait until WU's expire to send them out to be completed.
Please consider either completing what's in the queue or ABORTING them. Thank you. :)
About the Proth Prime Search
The Proth Prime Search is done in collaboration with the Proth Search project. This search looks for primes in the form of k*2^n+1. With the condition 2^n > k, these are often called Proth primes. This project also has the added bonus of possibly finding factors of "classical" Fermat numbers or Generalized Fermat numbers. As this requires PrimeFormGW (PFGW) (a primality-testing program), once PrimeGrid finds a prime, it is then tested on PrimeGrid's servers for divisibility.
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 accomplished that, increased the goal to n=800k, then expanded to include sub-project Proth Prime Search Extended (PPSE) for odd 1,200<k<10,000 and the Proth Mega Prime Search of numbers larger than 1m decimal digits for odd k<1200. Small primes are still important as they may lead to new factors for "classical" Fermat numbers or Generalized Fermat numbers. While there are many GFN factors, currently there are only about 334 "classical" Fermat number factors known. Current primes found in PPS definitely make it into the Top 5000 Primes database.
We're currently searching n>2.54m for odd 300<k<600 in PPS, n>1.46m for odd 1200<k<10,000 in PPSE and n>3.44m for odd 500<k<1200 in the Proth Mega Prime Search.
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 numbers. 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.
Since then a great deal of proth primes have been found, including over 92 mega primes!
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.

Hi
I:ve a Question ;
My Graca is GTX 1080 TI ( Windows 10 )
for PPS ( Sieve ) Running Time is 2 Min 55 - 3 Min 02 sec

You won't get from 3 min to 2 min by overclocking. You can probably improve it though. PPS Sieve seems much more forgiving to overclocking than GFN.

At this late stage I'd suggest running "as is" if that is known stable. The risk from overclocking is you may get bad results, or crashes when you are away from the system. That could cost you more in lost time for the challenge than you gain. If you had looked at this earlier before the challenge, you would have time to check it is ok before doing it. Edit: just noticed the original post was some days earlier... didn't see until now.
BTW my 1080Ti (Asus Strix OC version) seems to be averaging 176 seconds a unit. |

That's impressive. My watercooled 1080 is only getting about 267 seconds per task (although it's only at 85% power target) |

For anyone looking for an inexpensive crunching card I can't recommend the GT 1030 enough.
In this challenge I'm running a GT 1030 and a GTX 1050ti. The 1030 (~1700 seconds) is 53% of the performance of the 1050ti (900 seconds) at 39% of the cost up front and much cheaper on the electric bill. Two 1030's would be better throughput than a single 1050ti and still cost less to buy and operate.
Maybe in my next system refresh I should buy several 1030's and crunch on them and leave a bigger card just for gaming and day to day operating. haha

Multiple tasks per GPU? How? (If your willing to share)
Edit: Found it!

Had it working, but it really went haywire with my CPU tasks. I have 2 GPU's in the computer in question. Back to the tried and true one per.

After day 1, here's the statistics:
Challenge: Winter Solstice
App: 9 (PPS-Sieve)
(As of 2017-12-19 16:32:30 UTC)
300362 tasks have been sent out. [CPU/GPU/anonymous_platform: 35489 (12%) / 264220 (88%) / 653 (0%)]
Of those tasks that have been sent out:
15807 (5%) came back with some kind of an error. [8344 (3%) / 7463 (2%) / 0 (0%)]
190039 (63%) have returned a successful result. [1977 (1%) / 187615 (62%) / 451 (0%)]
94638 (32%) are still in progress. [25168 (8%) / 69267 (23%) / 202 (0%)]
Of the tasks that have been returned successfully:
57823 (30%) are pending validation. [497 (0%) / 57217 (30%) / 113 (0%)]
132215 (70%) have been successfully validated. [1480 (1%) / 130397 (69%) / 338 (0%)]
1 (0%) were invalid. [0 (0%) / 1 (0%) / 0 (0%)]
0 (0%) are inconclusive. [0 (0%) / 0 (0%) / 0 (0%)]
Normal daily volume recently was about 50,000 tasks per day, so the challenge is about 4 times the normal traffic. That might not sound like a lot, but PPS-Sieve is, by far, our most popular project, so a lot of the available GPU computing power at PrimeGrid was already running PPS-Sieve before the challenge. And now we're doing four times as much. That's pretty impressive.

Always amazed at how many credits the top ranked participants can generate.
Here's a couple fun facts:
If tng* had created a new profile just for this challenge, as of day 1 he would be ranked #2,707 in the world. An estimated rank of #1288 by the end of the 3 days.
Had Sicituradastra. started a new team they would be ranked #236, roughly #133 by the end.
By the end of the challenge, the top 3 participants will have generated more credits than I have in my 730 days with Prime Grid. |

Very nice!

Two day in the books! Coming into the home stretch with just one day to go...
Challenge: Winter Solstice
App: 9 (PPS-Sieve)
(As of 2017-12-20 16:29:56 UTC)
541480 tasks have been sent out. [CPU/GPU/anonymous_platform: 43236 (8%) / 496935 (92%) / 1309 (0%)]
Of those tasks that have been sent out:
20814 (4%) came back with some kind of an error. [9340 (2%) / 11474 (2%) / 0 (0%)]
421237 (78%) have returned a successful result. [8962 (2%) / 411209 (76%) / 1103 (0%)]
99559 (18%) are still in progress. [24934 (5%) / 74407 (14%) / 206 (0%)]
Of the tasks that have been returned successfully:
70119 (17%) are pending validation. [1035 (0%) / 68967 (16%) / 154 (0%)]
351117 (83%) have been successfully validated. [7927 (2%) / 342241 (81%) / 949 (0%)]
1 (0%) were invalid. [0 (0%) / 1 (0%) / 0 (0%)]
0 (0%) are inconclusive. [0 (0%) / 0 (0%) / 0 (0%)]
Half a million tasks sent out, over 420 thousand returned. That's a lot of sieving!
Compared to LLR or Genefer, the PPS-Sieve is very, very reliable. Only a single invalid task so far.
The overall failure rate is about 4%. That's not calculation errors as much as it is configuration errors. For one reason or another, the computer simply isn't able to run a BOINC task. It rarely has anything to do with the app itself. What's interesting is that the number of failures on CPU tasks is almost as high as the number of failures for GPU tasks. There's a lot more things that can go wrong with a GPU.

With one day remaining in the challenge, it's time for our public service announcement about being a good netizen as the challenge is completed...
At the Conclusion of the Challenge
We would prefer users "moving on" to finish those tasks they have downloaded, if not then please ABORT the WU's (and then UPDATE the PrimeGrid project) instead of DETACHING, RESETTING, or PAUSING.
ABORTING WU's allows them to be recycled immediately; thus a much faster "clean up" to the end of a Challenge. DETACHING, RESETTING, and PAUSING WU's causes them to remain in limbo until they EXPIRE. Therefore, we must wait until WU's expire to send them out to be completed. Thank you!
Special note for December:
There's little more than 10 days between the end of this challenge and the start of the New's Years Challenge. You might want to pay special attention to when long-duration tasks are going to complete so that you're ready to kick off 2018 with SoB!

Lot's of new, expensive GPUs. And lots of power.
Maybe some cloud-based GPUs too. (It's only three days.)

I am still in tears over the suspension of PPR12 (PSA badge). My 1080 and 1060 arrived a couple of weeks (at best) before the plug was pulled but during that very brief period of PrimeGrid bliss and nirvana I was pulling in SEVEN MILLION credits per day. It is now suspended ... damn it! :-( |

Never mind there's a whole smorgaboard if new manual sieving to get through (mainly GFN20 it looks like is the priority) so that will help compensate :). Don't think I'll be doing any until late next year though as I'm at 90M already. |

We're not sure what gave you that impression, but we don't have any particular priorities for sieving at this time.

That's impressive. My watercooled 1080 is only getting about 267 seconds per task (although it's only at 85% power target)
Mine is at 233 seconds not oc'd and no strix.
1080? What clocks is it running at?
Mine is a 1080Ti and is running 1898 gpu and 5005 memory.
Try running 2 tasks at once next time. My 1080 was doing a task every 211 seconds on average once I switched to 2 tasks at once |

The PPS Sieve race is over, so I suppose I should post my optimized app_config files:
For Nvidia:
<app_config>
<app_version>
<app_name>pps_sr2sieve</app_name>
<plan_class>cudaPPSsieve</plan_class>
<cmdline>-m64</cmdline>
</app_version>
</app_config>
For AMD GPUs:
<app_config>
<app_version>
<app_name>pps_sr2sieve</app_name>
<plan_class>openclatiPPSsieve</plan_class>
<cmdline>-m16 --vecsize=1</cmdline>
<avg_ncpus>1</avg_ncpus>
<ngpus>0.5</ngpus>
</app_version>
</app_config>

And we're done!
Here's the final statistics:
Challenge: Winter Solstice
App: 9 (PPS-Sieve)
(As of 2017-12-21 16:43:51 UTC)
783466 tasks have been sent out. [CPU/GPU/anonymous_platform: 49466 (6%) / 732045 (93%) / 1955 (0%)]
Of those tasks that have been sent out:
39936 (5%) came back with some kind of an error. [18029 (2%) / 21907 (3%) / 0 (0%)]
661070 (84%) have returned a successful result. [15313 (2%) / 644006 (82%) / 1751 (0%)]
77109 (10%) are still in progress. [14128 (2%) / 62503 (8%) / 196 (0%)]
Of the tasks that have been returned successfully:
63290 (10%) are pending validation. [914 (0%) / 62055 (9%) / 136 (0%)]
597779 (90%) have been successfully validated. [14399 (2%) / 581950 (88%) / 1615 (0%)]
1 (0%) were invalid. [0 (0%) / 1 (0%) / 0 (0%)]
0 (0%) are inconclusive. [0 (0%) / 0 (0%) / 0 (0%)]
The thing that stands out, other than 661,000 tasks being completed, is that there was only one bad result. Ken definitely deserves a round of applause for this!
The other thing that stands out is the tremendous amount of GPU firepower that was brought to bear on this challenge. The first place individual (same person in both years) improved from 67 to 85 million points. The first place team (again, the same team in both years), improved from 254 million to 385 million.
While we're going to wait for all the validations to complete before declaring the official winners, since there was only one bad result during the challenge, it's safe to say that tng* and Sicturadastra. will end up being the winners of this challenge. Congratulations!
(In fact, Sicturadastra.'s lead is so large that they are already officially the team winner, regardless of what happens during the cleanup.)

And now the cleanup starts. I doubt any results will change, but we'll go through the motions anyway. I expect the cleanup to take between 2 and 5 weeks.
Cleanup Status:
Dec-22: Winter Solstice: 64214 tasks outstanding; 55734 affecting individual (297) scoring positions; 26113 affecting team (75) scoring positions.

Congratulations to all, another year done. I had app_config CULs chime in once CPU sieving was done & for some reason *pause* my GPU work in the last hour costing possibly 1 unit... |

Grrr...
What in the name of all that is holy are the top guys using as computers? How much money do they have to invest? I'm so envious, I'm also very happy that I'm not sitting at the bottom of the list.
They are using cubic dollars... as computers?
I was running on 5 gpus, and was placed 100-th.
TNG had 18 times more powuh on hand.
I was using 20000 gflops peak by boinc, whatever that means. |

I had 16 gpu's and was 31st! I did only run one task at a time though, next time I will try running multiple workunits at a time.

I think I ran 10 different GPUs at some point during the challenge, but at the end only 5 were full time as I couldn't deal with the heat output. Still, that got me 30th and if it weren't for thermal limitations, I probably could have got some more places higher.
The ones I left running were best suited to the task at hand, and not too old. |

I did pretty good considering the participants here.
A GTX 1050ti and a GT 1030 got me into 244th place. Given that there were 1063 participants I'm happy.
I thought about putting in my GTX 760 as it would have been my fastest card for PPS SV, but the heat and noise (especially the noise) weren't worth it.

I am having an issue on 2 machines where I abort the cpu task but it still continues to run. Boinc shows them as aborted but in task manager they are still there. A reboot took care of it but I wanted to post just in case this is a bug or others run into it but are unaware.
Both machines were win 10 btw :(

If I had run 2 units concurrently on the GTX 760, I would have completed 16% more work and be 20 places higher in the ranking, from 304th. But the computer would have been pretty useless interactively. |

138 CPU threads running for just about half the challenge
Just got too hot to keep the CPUs running tasks
All of that produced 25,272,387 points in the three days.
I placed 15th, I am very please with that.
Now with all that I had running, I was only 15th.
There is a lot of processing power in people hands today.
I lost one hour when my system updated to the new win10 and rebooted on me
That was the 1080 with 11 threads crunching too.
Glad I caught it and only lost an hour!
It was fun, glad I was able to do it.
Merry Christmas / happy holidays and a happy new year to everyone.

I also had this problem on my Windows machines. Fortunately tasks can be killed from Task Manager, reboot is not necessary. Linux seems to works fine - at least BoincTasks reported CPU usage close to 100% for new WUs which started after aborted ones.

What does your app_config.xml file say to allow you to run 11 unit at once? I have a 1080Ti and only ran one at a time so it would be nice to utilize my card better next time.
I had the same problem on several pc's that wanted to update too, fortunately I was able to get them to not do it right then, I'm still trying to put it off until after Christmas. On older slower pc's it's longer than an hour even with an SSD as the hard drive. |

Maybe 1 thread for the GTX 1080 and 11 threads for CPU Sieving. |

That is right, I run two tasks on the GPU, one thread to feed the GPU
Then one task per CPU thread.

Ahhh okay that makes sense...I was thinking 11 gpu threads utilizing the 11gb of memory on the 1080Ti cards. Now THAT would be sweet if that would work but with 32 bit apps I know it won't.

I run 8 to 10 Milkyway tasks at the same time on my 6gb Titan
That Titan is a beast when it comes to the Milkyway project.

Now that the final challenge event for 2017 is completed can we get the overall 2017 results now please?
Just for fun, I've made a program (C/C++ with QtCreator, Windows) to consolidate the challenges results.
I'm currently testing it by checking its output against the "Current Overall Results" of previous years.
Please note I'm not a pro programmer.
I just did this hoping it could be helpful somehow.
I've found some discrepancies when compared to the just released spreadsheet in Google Docs (which is an awesome work done, btw).
//=======================================
The first point I'd like clarification with is the final user rank, when there is more than one user with the same final score in a challenge.
Do they all get the same rank ?
This is the way it was done in 2017 last challenge (Winter Solstice Challenge).
For instance, there were 2 users ranked 102th.
The next user was ranked 104th.
No user was ranked 103th.
But the same was not done in the 3rd challenge of 2017 (PrimeGrid's Birthday Challenge).
There, for example, two users were ranked 114th and 115th (different ranks) although they had the same final score.
Since the challenge points are awarded according to the "Individual Challenge Points" table based on rank (place), it does make a difference how you rank two users with the same score in a challenge.
For instance, in the PrimeGrid's Birthday Challenge, my program ranked michael-u5a1, unyora and Zack at 296th place, since the 3 of them got identical 3272.91 score.
Since this was a 1 day challenge, for my program, they all got 14 challenge points.
But the released spreadsheet shows Zack with 12 points, which means it considered Zack to have finished in 298th place in that challenge.
//=======================================
Another issue relates to Daniel, of BOINC@Poland.
My result puts him in 11th place overall.
The spreadsheet puts him in 31th place.
The spreadsheet says he got zero points in last year seventh challenge Pierre de Fermat's Birthday Challenge, which means he would've finished beyond place 300.
But if you look at the challenge results, you'll see he got the 25th place.
He should have gotten 926.70 points for this 3 day challenge, not zero poits.
//=======================================
The spreadsheet lists another Daniel, of BOINC@AUSTRALIA, in 44th place overall.
But I could only find him in a single challenge (the first one in 2017) and he finished that challenge in position 489, which means he didn't get any challenge points.
Since he only participated in one challenge and didn't score any challenge points, he should not be in 44th overall.
BTW, there are many users with the same user name.
Daniel is a fine example. In the 2017 challenges we had:
Daniel of BOINC@Poland
Daniel of BOINC@AUSTRALIA
Daniel of Calm Chaos
Daniel of "no team"
To avoid confusion, I ended up using the user id, instead of the user name, when extracting info from the challenges webpages.
//=======================================
One last comment, the Overall Standings for 2016 does not include that year last challenge (Winter Solstice Challenge).
It's easy to get the consolidate overall result for 2016, including this missing challenge, with the program (assuming it is working correctly).
For now, the output is a text window, with tab separated values (easily pastable in Excel):
Overall rank - User Name - User Team - Points in each challenge ... - overall points
If there is any insterest in thisl, just let me know.
I'd be glad to make any needed modifications.
Edit:
This is what I'm getting
Overall 2016 Challenge Series Standings
Overall 2017 Challenge Series Standings |

Thanks for taking an interest.
It took me 3 hours to add the last 2 challenges to the spreadsheet.
I used simple copy and paste and Spreadsheet formulas, nothing fancy. What is done in the spreadsheet may not be best practice.
If two users have same score in a Challenge then should be awarded same Challenge Points.
Going by user id would be superior to just the user name. I noticed multiple instances of same User Name. I didn't investigate if ID was the same.
I'd have to go through the points you raised later, when I get home to confirm discrepancies.
Ideally we'd end up with the same results.
I only recently went to the effort of tallying the Challenge points, so hadn't looked at 2016. |

That's great, Roger.
We'll eventually converge to the same results.
