Welcome to the Oktoberfest Challenge!

The sixth Challenge of the 2019 Challenge series is a 5 day challenge to celebrate Oktoberfest. The challenge will be running on the AP27 Search.

Oktoberfest is the world's largest Volksfest (beer festival and travelling funfair). Held annually in Munich, Bavaria, Germany, it is a 16 to 18-day folk festival running from mid or late September to the first weekend in October, with more than six million people from around the world attending the event every year. Locally, it is often called the Wiesn, after the colloquial name for the fairgrounds, Theresa's meadows (Theresienwiese). The Oktoberfest is an important part of Bavarian culture, having been held since the year 1810. Other cities across the world also hold Oktoberfest celebrations that are modelled on the original Munich event.

During the event, large quantities of Oktoberfest Beer are consumed: during the 16-day festival in 2013, for example, 7.7 million litres were served. Visitors also enjoy numerous attractions, such as amusement rides, sidestalls, and games. There is also a wide variety of traditional foods available.

This year Oktoberfest will start on Saturday, September 21st. The Schottenhamel tent will be the place to be if you want to catch the official opening ceremonies. At noon, the Mayor of Munich will have the honor of tapping the first keg of Oktoberfest beer. Once the barrel has been tapped, all visitors will then be allowed to quench their thirst. The festival will go until Sunday, October 6th.

Arithmetic progressions
In mathematics, an arithmetic progression (AP) or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant. For instance, the sequence 5, 7, 9, 11, 13, 15 … is an arithmetic progression with common difference of 2.

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.

How to Participate?
To participate in the Challenge, please select only the AP 27 (AP27) project in your PrimeGrid preferences section. The challenge will begin 21st September 2019 11:00 UTC and end 26th September 2019 11:00 UTC. Application builds are available for Linux , Windows and MacIntel CPUs and GPUs. CPU apps are only available for 64 bit CPUs. High end Nvidia GPUs will have a very large advantage.

Tasks will take ~29 hours on average for CPUs and ~75 minutes on average for GPUs. If your computer is highly overclocked, please consider "stress testing" it. If you haven't run the AP app before, we strongly suggest running it before the challenge while you are monitoring the temperatures. You don't want to turn your machine into a meteor!

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 tasks issued AFTER 21 September 2019 11:00 UTC and received BEFORE 26 September 2019 11:00 UTC will be considered for credit. We will be using the same scoring method as we currently use for BOINC credits.
A quorum of 2 is NOT needed to award Challenge score - i.e. no double checker. Therefore, each returned result will earn a Challenge score. Please note that if the result is eventually declared invalid, the score will be removed.

At the Conclusion of the Challenge

ABORTING tasks allows them to be recycled immediately; thus a much faster "clean up" to the end of a Challenge. DETACHING, RESETTING, and PAUSING tasks causes them to remain in limbo until they EXPIRE. Therefore, we must wait until tasks expire to send them out to be completed.

Please consider either completing what's in the queue or ABORTING them. Thank you. :)

The front page shows standings for all challenges that are either currently running, or are still in clean-up. There's often more than one set of challenge leaderboards displayed.

But sometimes, as is the case right now, there's no challenges that are either running or in their cleanup. Rather than displaying nothing, the front page displays the most recent challenge leaderboards until the new challenge starts. Then it will show the leaderboards for the active challenge.

This is the Oktoberfest Challenge.

This is the leaderboard display on the front page right now (emphasis added):

Lennart Vogel Honorary Challenge (ESP-LLR): Individuals | Teams

Also, if you were to click on either the Individuals or Teams links, if the fact that there's already scores for a challenge that hasn't started yet didn't give it away, then the start and end dates, both in August, should be a dead giveaway that you're looking at the wrong challenge.

Probably a small herd but we are definitely joining the challenge again!
You never know when a herd turns into a stampede.

Edt: just tested a few AP27s and already found my first prime, I guess my luck has turned ;)

What driver version are you using? One of the recent Nvidia drivers is known to have problems in the CUDA/OpenCL section.

Also, the driver versions you get from Microsoft instead of Nvidia usually have the CUDA/OpenCL section removed.

Munich's Oktoberfest has officially opened, with Mayor Dieter Reiter tapping the keg.
Fast start to the Challenge. Already 207 Users and 55 Teams have returned tasks.

Last AP26 was found in November 2018:
Remember to check you AP Discoveries.
Give a shout out if you find any big ones.

I am using 436.15 from nvidias site and it seems to generate no errors.

The 436 drivers are known to generate problems for one type of workunit from SETI@Home, but not for some of the similar other types.

I use the 431.60 driver, the most recent release known not to have that problem, and I don't get errors either.

If you want to try it also, go to:

Scroll down to the Beta, Older drivers and more section.

Click on Beta and Older Drivers.

Note that the Nvidia program that normally checks whether a newer driver is available must be uninstalled if you do this, or it will keep trying to install the 436 driver.

Actually, nobody asked for links, but I thought they'd be nice, especially with over 3000 AP sequences discovered so far during the challenge.

I have modified the personal account pages (.e.g., https://www.primegrid.com/ap.php?userid=53948) that show all of a person's AP discoveries. I have also modified the AP status page (https://www.primegrid.com/stats_ap26.php) that shows all of PrimeGrid's AP23 and longer discoveries. They now show links to the tasks that found the AP, if possible.

Also, the PrimeGrid AP status page now shows links to the expanded AP sequence. (The personal pages always showed these links.)

Enjoy!

As I mentioned in that thread, I have a table version of the page, but that table is harder to sort than most. Getting it sortable may take some time.

It must be an equinox AP27. Sun will pass the Equator (from north to south) at 07:50 UTC (in about 20 minutes from now).

27 full Oktoberfest beer mugs go to the lucky finder. Cheers!

The identity of the lucky cruncher was revealed on the PrimeGrid Discord chat server [external] (see link under "Community"). So I am being an advertisement for that chat room. Do not waste your time in there, though. /JeppeSN

These statistics seem kind of boring after the big news!

After two days:

Challenge: Oktoberfest
App: 11 (AP27)
(As of 2019-09-23 00:59:07 UTC)

111574 tasks have been sent out. [CPU/GPU/anonymous_platform: 15958 (14%) / 95616 (86%) / 0 (0%)]

Of those tasks that have been sent out:

This is so exciting. Hopefully it means good luck for the Fermat Divisor challenge coming up, it would be fun to have multiple challenges this year that make progress on the corresponding project apart from just advancing the leading edge by a ton.

The speed of the hardware doesn't matter when you set your BOINC cache high and give the other guy a 12 hour head start on a task that only takes minutes to run.

Wasn't Robish very lucky, since the other task was assigned to a computer with a big cache ? :)

The previous table shows all the APs found during the challenge of length 24 or greater. We've found many shorter AP sequences as well. Here's the counts for all sizes:

With ten hours remaining in the challenge, it's time to remind everyone...

At the Conclusion of the Challenge

When the challenge completes, 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.

Likewise, if you're shutting down the computer for an extended period of time, or deleting the ViM (Virtual Machine), please ABORT all remaining tasks first.

Thank you!

There's one more AP25 and eight more AP24s waiting for wingmen. Those are not included in either of those tables.

Well done everyone!

This was definitely the most exciting challenge I've ever participated in. In about 2 weeks, we have the World Maths Day challenge on the new Fermat Divisor (PPS-DIV) project. Will we be as successful and find set a world record by finding the largest known Fermat divisor?

Thank you for organizing the Oktober Fest, great crunching!

I have residuals downloaded during the competition in work caches on 2 PCs.

I can finish these work units, but do they count as valid in the results please? If not the CPU units could be aborted as they are slower, to be re-issued to another user to help a cleaner finish?

I think I have a 24 waiting to validated, here's hoping!

They count as valid for your regular credit and badges. They do not count for the challenge score. And, of course, anything you discover is real, regardless of when you run task.

I think I have a 24 waiting to validated, here's hoping!

The ones already waiting to be validated count for both regular credit and challenge score, as long as the correct result was returned.

With the AP27 discovered and this project's goal achieved, we are considering the future of the AP27 project. One possibility is that it may shut down.

That discussion is in this forum thread.

There's going to be a tie for 300th place for individuals, and also for 100th place for teams. We will therefore have 301 individuals and 101 teams scoring points in this challenge.

Is this a first or has it happened before? I don't remember you mentioning it but then my memory is not that good.

I don't remember either.
One way to check it is to go to the PrimeGrid Challenge Series Results and for each year check the standings.
Columns are sortable.
If you click on a column header, you'll get the table sorted (in ascending or descending order) according to the contents of that column.
If the columnn is name/team, rank or total points, you'll get the the usual alphabetical/numerical ordering.
If it is a challenge column, you'll get the the table sorted according to the participant (user or team) rank that challenge.

Ties happen frequently when there's a challenge where the tasks all generate the same credit (AP27 and sieves). It's almost impossible with LLR or Genefer.

I wanted to make sure that anyone running a challenge statistic site was aware there's more than the normal number of people and teams getting points this time.

Good note on the same credit.
Indeed it has happened before, once at least (I haven´t looked further).
In 2015, in the last challenge (Winter Solstice [PPS-Sieve])
there were 4 users tied in 298th place and 2 teams tied in 100th place.
So, 301 users and 101 teams received points in that challenge.
https://statsgr.id/overall/2015_Challenge_Series_Final_Standings_Individuals.html
https://statsgr.id/overall/2015_Challenge_Series_Final_Standings_Teams.html
I've included the sub-project name(s) in the challenge column header.
