Tour de Primes 2014
Welcome to the 6th annual Tour de Primes. 2 is the first prime number...and the only even one. This makes it unique among prime numbers. Therefore, February is declared Prime month...being the 2nd month of the year. :) And there's no better way to pay homage to a prime number than to go out and find one. :) More precisely, a Top 5000 prime.
For the month of February, an informal competition is offered. There are no points to be gained or awards to be won...just a simple rare jersey at the end of the month to add to your badge list. No pressure or stress other than what you put on yourself. :)
 Yellow Jersey - prime count leader
 Green Jersey - points (prime score) leader
 Polk-a-dot Jersey - on the 19th of February we'll have a "mountain" stage and award the Polk-a-dot Jersey to the one who finds the most primes on that day (tiebreaker will be prime score for that day).
We are currently working on an overview for the Tour de Primes 2014. This post will be updated with links when it's available. Note that this might be a day or two after the start!
Currently, the fastest opportunity to find Top 5000 primes is with the PPSE (LLR) project. Of course, should someone find a prime in the higher n searches, this would pretty much guarantee the green jersey. Should you bag a GFN prime, whether it's a world record or "small" one, you're pretty sure of a win too. All ports in PRPNet except for the GFN32768 port are also available for the competition.
To participate in BOINC PPS(E) (LLR), all you have to do is select it in your PrimeGrid preferences.
To participate in PRPNet, please see the Welcome to PRPNet thread.
Good Luck, have fun, and enjoy! :D

The 2014 Tour de Primes page can be found here: http://www.primegrid.com/challenge/tdp_2014.php
Right now, it's showing data from different dates for testing. It will be set to show the correct dates (all of February for Tour de Primes and February 19th for the mountain stage) before TDP begins.
Let me know if there's anything that doesn't work on the new page.

Sorry for the late notice but is it possible to add a team element to the TdP?
I don't know if it's possible to reward team badges but it could be a fun and informative tool.
I also had an idea how to do it:
It makes no sense to somehow combine the scores of members of an entire team (otherwise bigger team would have an edge and smaller ones almost no chance).
But what if we combined only the top 5 (number flexible) scorers of each team (similar to the way team time trial races are timed in TdP's name patron Tour de France).
To sum up, the prime scores of the top 5 members of each participating team are added up and at the end we'll see which team has the highest combined score. |

It's not possible, sorry. The team information isn't stored with the primes, so all we know is what team the user is in right now, not what team they were in when the prime was found. Because of that, when a user switches teams, the team scores would change too. That would make the team scoring rather meaningless.

In the two Tour de Primes I've been in I've not found a prime.
This year I am going to be running SR5 and GFN short as long shot chances.
Will take my SR5 badge to Gold at least.
Anyone else not running PPS on their CPU's?

I'll run SoB and short GFN, expecting a second green Jersey :)
The problem with long tasks is the time you might have to wait for a wingman to return a valid result. If a prime is found in February, but only validated (through a matching result) later it, will not count to the Tour, right?

Wrong!
We've vastly improved the way BOINC primes are handled this year. In short, it works they way you'd expect it to work.
If you find the prime during February, on either BOINC or PRPNet, it WILL count for Tour de Primes, regardless of when the double check occurs. We'll have to wait for the double check to finish (or for us to manually verify the prime) before the TDP stats are final, but this year, it's when you find the prime that counts rather than when the double check happens.

Initially I'll be running SoB mostly, with some SGS and SR5. Later I'll stop running SoB, and eventually SR5, but that's in preparation for the SoB challenge.
Running GFN-WR on all GPUs that can.
I'll take on long shot on the green jersey this year.

That's good news. On the other hand, the green jersey might take a while to be granted.

If it's a GFN-WR, it will. Then again, if it's a GFN-WR it will be really big news. Other mere mortal numbers will at worst take a couple of days for us to verify. It's conceivable we might not wait for the actual double check before finalizing the standings if we've verified the prime(s) internally.

Good guess (it is in fact an SR5), and we've internally verified the prime. We're just waiting on the DC to report back in. Funny thing is, under the old messed up rules for BOINC primes we used in previous years, this prime would have counted in the challenge (assuming the DC does get reported in February) and likely would have won the Green Jersey.
It wouldn't surprise me if one or more SR5 primes are found during February.

I am running PPS(extended). Is that the right thing to run for Tour de Primes?
I am getting a lot of valid errors and short tasks. Is that normal. I am also running some SOB's that I started a little earlier. Will they count? I put an image with my profile so when will it show u? |

Hi Lee,
Yes, PPS (Extended) is suitable to participate in the challenge. All sub-projects which aren't sieves are eligible, as they could give you a prime. However, all those validate errors you're seeing are a well known problem which is being discussed over here.
Any prime that is reported during Februari counts, regardless of when you started your calculations.

Any project capable of finding a prime eligible for inclusion in the Top 5000 Primes list is fine. Remember, this challenge is about finding primes. Merely participating doesn't get you anything as far as the challenge is concerned. It only counts if you find a prime.
All PrimeGrid BOINC projects except for the PPS-Sieve and TRP-Sieve count for this challenge. (You can't find a prime with a sieve). On PrimeGrid's PRPNet, all ports except GFN32768 are eligible. (GFN32768 produces primes which are too small). Manual sieving is not eligible because sieving can't find primes.
I am getting a lot of valid errors and short tasks. Is that normal.
That's a problem. I see that's happening on two of your three computers. We don't fully understand this problem, unfortunately. It started happening about a year ago. It seems to be more common on computers running Windows 8, but I'm not certain that Win 8 is the cause.
Please see this discussion for more information about the 3 second problem.
I did notice that your machine with the GTX 260 GPU had run several GFN tasks last month, and all failed to validate. That problem's cause is well understood. The GPU is overclocked too high for running GeneferCUDA. Lowering the clock speeds, especially the memory clock, will help. (Note that even "factory overclocked" is still overclocked and will cause problems with that application.)
I am also running some SOB's that I started a little earlier. Will they count?
If you find a prime, then yes they will count.
I put an image with my profile so when will it show u?
It seems to be already displayed. Note that there's a difference between the picture in your profile and the avatar that is displayed on the forums. If you want to display a picture ("avatar") under your name on the forums, you need to click on the Community Preferences link on your account page.

Update as of 5 February @ 14:22 UTC:
If you happen to look at PrimeGrid's homepage, you may notice that it's showing "?" as the Top 5000 position for all projects. That's happening because the Top 5000 website is currently unreachable for whatever reason.
This has an impact on the Tour de Primes status page (http://www.primegrid.com/challenge/tdp_2014.php) because a prerequisite for any primes showing up on the TDP status page is that it must have been reported to the Top 5000 Primes site first. Since that site is down, and it's therefore impossible at the current time to report primes to that website, no new primes will show up on our Tour de Primes status page.
Once the Top 5000 website starts working again, our TDP status page will resume updating normally.

The "deja vu" part was because the prime was found by the same computer (and obviously the same person) as the SR5 prime that was found on January 31st!
22934*5^1536762-1
That is literally a prime-finding machine!
The prime was found by Keishi Toda and Scott Brown is the double checker. Congratulations to both of you!
For those who are interested in how you find 2 mega primes in a week (consider that in all of history, only 78 mega primes have ever been found), it doesn't hurt to have a 6 core Sandy Bridge-E CPU that can crunch 6 SR5 tasks every 2.5 hours. And it helps to be very, very lucky!
Once again, congratulations!

It's a bit premature for that.
For one thing, I wouldn't be surprised if we find more SR5 primes this month. They'll be even larger. Also, it's entirely possible that the green jersey can be won by someone finding lots of PPSE primes.
That SR5 prime has a prime score in the vicinity of 1400 if I remember correctly. You need 20+ PPSE primes to get that high a score, which is not impossible.

You're right. x-RaY99 just turned in four PPSE today alone, and is on track to beat 1400 by month's end.

There was a discussion in the chat room about what it would take to win the green jersey with a single large prime. Which project would be the best to run looking for a mega prime which would be large enough to capture the jersey? On the BOINC side, here's the prime scores of the largest candidates currently loaded into the database:
GFN:
+---------+-----------------+
| n | prime score |
+---------+-----------------+
| 8192 | 0.0429 |
| 16384 | 0.3400 |
| 32768 | 2.6271 |
| 65536 | 19.4153 |
| 131072 | 144.7669 |
| 262144 | 4,462.0848 |
| 524288 | 36,757.0763 |
| 1048576 | 267,945.4290 |
| 4194304 | 10,609,470.5761 |
+---------+-----------------+
LLR:
+---------+--------------+
| project | prime score |
+---------+--------------+
| PPSE | 58.9996 |
| SGS | 65.0004 |
| PPS | 863.3470 |
| SR5 | 1,672.2780 |
| TRP | 34,789.1578 |
| 321 | 46,123.8269 |
| CUL | 49,929.9926 |
| WOO | 72,626.0292 |
| PSP | 149,624.1785 |
| SOB | 389,108.4925 |
+---------+--------------+
I'll leave the PRPNet sizes as an exercise for the reader. The formula is X^3 * ln(X) * C, where X is the size of the prime computed as ln(k) + ln(b) * n and C is 1/150732545640984000.
Just to be clear, ln is the natural logarithm. In both Excel and SQL the function is ln().

Assuming that those scores are the same as the ones here, that would mean that TRP is the easiest project that would (probably) win with a single prime, right? |

Correct on both, if you're only considering BOINC.

How about giving computers with slower clock rates a shot at the green jersey too, by setting initial replication = 1 during TDP for LLR projects? A slower computer really only ends up double-checking as it is beat to the punch every time by a faster wingman that only has just enough tasks on the go to keep all cores busy.
This also maximizes the chance of finding a new megaprime during TDP. |

The system isn't set up to work this way. Once a quorum is achieved (even if it's a quorum of 1), the result is moved into the science table. A prime never validates without two matching results. If a quorum 1 PPSE or SGS task shows as prime, the validator increases the quorum to 2 and creates a new task. It then waits until that new task returns before revisiting that workunit.
If you run SGS, PPS or PPSE workunits and have a dependable host, you'll get jobs with an initial replication (and quorum) of 1. Then you won't be competing with anyone based on time.

True, but the incredible amount of "3 second" errors is causing a lot more of initial quorum of 2 WUs than usual.

No, they're not. A 3-second error task is immediately rejected by a script - not the validator. The transitioner then creates a new task without touching the minimum quorum or initial replication. We have plenty of workunits with 3-second errors that are then completed as a single task.
Example: http://www.primegrid.com/workunit.php?wuid=382537737 |

All my current hosts are getting work with quorum of 1. however, most (or at least a very large number) of tasks are coming with a quorum of 2 (i'm getting the second task), which, I believe, means that the other host is not considered reliable by the server. I assumed that a "3 second error" host would not be considered reliable for ar, hence causing a quorum of 2. But you are right, I've seen some tasks returned after 3 seconds being validated with the quorum of 1.

Today is the Mountain Stage! There's a special jersey badge to the person who finds the most primes today. Today is defined in UTC, so as I write this there's about 7.5 hours to go.
I know there's nothing showing on the Mountain Stage prime list yet, but that has to wait for wingmen to verify the prime and for the prime to be reported before it can be displayed. There was at least 6 primes found today when I last checked.
Good luck!

I just received one of those e-mails :)
My homepage amazingly shows 3 new primes today, but I bet I'm just the double-checker on the other 2.

If you reported the prime during the Mountain Stage timeframe, I think it will count. I think there are a few more primes yet to be doublechecked and/or verified that will also count towards the polk-a-dot Jersey. Congrats eitherway!

I'm not sure if it was, though. I got the email 19 minutes before this post now... Idk how much of a delay there is between it, idk if it is 3 hours though. It would take 3 1/2 hours ago for it to count... Crossing my fingers!

There ia still one (at least) missing. Unfortunately, I guess I'm just the double-checker.

As of right now there are still two primes for the mountain stage missing. One of them is the prime you mentioned, where you are, indeed, the double checker.

How many still waiting for validation?

All the primes from the mountain stage are validated.

So when do we find out if we found a prime of any kind? |

You'll get an email about it if you have your account settings properly configured. Go to the "Your account" page and click on "PrimeGrid preferences" and you will be able to set up automatic notification emails for yourself.

I just secured a double check. It looks like I will be ending the Tour with 2 primes and 1 double check. Overall it is a much better showing than I have had in years past, but of course I always could have been luckier.
EDIT: Turns out it was a primary find but I had not yurt received the email. Now I am feeling very lucky : )

Tasks complete for 2014 TDP:
509 PPSE
133 SR5
107 ESP
92 GFN short
53 GFN262144
26 GFN524288
5 GCW
No primes but at least I was trying to win the green jersey.
Previous two years of TDP I only tried to get on the scoreboard with PPS tasks and still didn't find one.
Congrats to all crunchers!

On the tour de primes page, new primes are still being listed, found after the end of tdp. there are 2 listed as found after Feb 28 00:00 UTC

I had a plan similar to Roger's, but it didn't work out any better for me. I was running TRP-LLR on CPU exclusively, except on the "mountain stage" day where I was on PPSE. On GPU I ran GFN-524288 on PRPnet until that was halted, then switched to GFN-Short on BOINC. I was shut down completely for a bit a couple of times due to travel.
Now ready to "switch gears" to PSP (and GFN-WR). Cheers and thanks all for the tour,

Good news and bad news.
The good news is that the new mechanics for counting BOINC primes in the Tour de Primes worked as intended, and all primes actually found during February were counted. This was especially important this year because all the primes found in February were found on BOINC.
The bad news is... it's working as intended, which means that primes aren't showing up on the list until they're reported to the top 5000 web site. In most situations people elect to let PrimeGrid do the reporting, but some folks like to report the primes themselves. We'll wait up to 19 days for the prime to be reported by the user, then the double checker gets a shot at it. If the double checker also has elected to do their own reporting and doesn't respond within 19 days, then we'll report it ourselves. At worst, therefore, there can be a delay of approximately 38 days waiting for people to report a prime.
We 're currently waiting on 12 such primes to be reported. Two of those were during the mountain stage.
In addition to those 12 primes, there's also 4 more primes that were discovered during February but not yet double checked. (One of those is likely to be an overclocking error.)

The Mountain Stage results are final!
Congratulations to Lonnie Christensen for winning the 2014 polkadot jersey!
We're waiting on 4 more primes to be reported in order for the entire Tour De Primes results to be final.

With the final 4 primes having been reported to the Top 5000 we can now announce the final standings! :)
Top 3 Prime Count:
- [DPC]x-RaY99_the_one_man_team (57 primes)
vinn [Czech National Team] (17 primes)
For the Universe ( Apaszko-Kaszkiety ) (8 primes)
Top 3 Prime Score
- [DPC]x-RaY99_the_one_man_team (57 primes, worth 3186.85 points)
yuyusuke@jisaku (1 prime, worth 1477.67 points)
vinn [Czech National Team] (17 primes, worth 957.35 points)
Top 3 Mountain stage
- Lonnie Christensen (1 prime, worth 257.60 points)
1998golfer (1 prime, worth 55.35 points)
zunewantan (1 prime, worth 55.25 points)
All in all 254 primes have been found in the month of February, worth a combined total of 20982.77244 points. Compared to last year we've found more primes, though they were a little bit smaller on average. Compared to earlier years though we found far fewer, but much larger primes.
A whopping 120 people managed to find at least one prime number during Tour de Primes.
All in all, these are some results we can be proud of all together. Thanks to any and all who participated.
