Welcome to the Wallis is Born Challenge
John Wallis (23 November 1616 – 28 October 1703) was an English mathematician who is given partial credit for the development of infinitesimal calculus. Between 1643 and 1689 he served as chief cryptographer for Parliament and, later, the royal court. He is credited with introducing the symbol ∞ for infinity. He similarly used 1/∞ for an infinitesimal. Asteroid 31982 Johnwallis was named after him.
Wallis made significant contributions to trigonometry, calculus, geometry, and the analysis of infinite series. In his Opera Mathematica I (1695) he introduced the term "continued fraction".
Wallis rejected as absurd the now usual idea of a negative number as being less than nothing, but accepted the view that it is something greater than infinity. (The argument that negative numbers are greater than infinity involves the quotient 1/x and considering what happens as x approaches and then crosses the point x = 0 from the positive side.) Despite this he is generally credited as the originator of the idea of the number line, in which numbers are represented geometrically in a line with the negative numbers represented by lengths opposite in direction to lengths of positive numbers.
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 18th November 2016 18:00 UTC and end 23rd November 2016 18:00 UTC. Application builds are available for Linux , Windows and MacIntel CPU and GPUs. High end Nvidia GPUs will have a very large advantage.
Tasks will take ~23 hours on average for CPUs and ~100 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.
Please, please, please make sure your machines are up to the task.
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 18 November 2016 18:00 UTC and received BEFORE 23 November 2016 18:00 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
We kindly ask users "moving on" to ABORT their tasks instead of DETACHING, RESETTING, or PAUSING.
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. :)

I note the following:
Wallis's birthday can be given as either 23 November 1616 or 3 December 1616.
In that period, England was not yet using the modern ("new style") calendar, the Gregorianske calendar, that is universal today. So at the day of his birth, it was 23 Nov in England and many other parts of the world, but 3 Dec according to other areas where they had switched to the new calendar.
For this reason, the 400th birthday of Wallis could be celebrated on either 23 Now or 3 Dec.

Good point!
Although the calendar changes were in 1582 weren't they?
My GPU times are all over the place - will post times when I can benchmark properly. |

Yes, the changes came in 1582, but only in Southern Europe (and its colonies). Many areas adopted the new system much later. So during the life of Wallis, two competing calendar systems existed. Which is why I mentioned it.
England, where Wallis was born and lived, did not follow the Pope as closely as some of the southern countries of Europe, and they stuck to the old calendar. Not before 1752, long after Wallis's death, would England (then part of the United Kingdom) make the switch.

hi,
It would be twice as appropriate to run the challenge from 23 Nov to 3 Dec.
And twice the length of the challenge, too :)

Been testing the AP27 app on some of my computers.
Am I right that it is not designed to run on 32bit? The scheduler refuses to give my 32 bit boxes any AP work, but doesn't say why.
I have also noticed that suspend-in-memory has been implemented differently to how it was done in LLR -- when an AP task is suspended the Linux command "ps" lists its state as "S" (interruptible sleep), whereas LLR shows up as "T" (stopped by job control). This difference makes no practical difference to me as a user, it was just unexpected.
Also ps lists the AP apps as being threaded, whereas LLR are not. Run times suggest that the threads do not run concurrently, or at least not to a measurable degree.
None of my boxes seem to complain about getting too hot, and all the run times are under five days so hopefully all my 64bit machines will contribute at least one WU per core/HT thread.

You are correct; there is no 32 bit app. If you look at the description of the project (where you select the project) you'll see that there's no 32 bit apps available.
As for the task suspension, that's done by BOINC itself, not the app. BOINC doesn't tell the app "go to sleep". BOINC tells the operating system "Put that process to sleep". If you're seeing a difference in behavior, it's probably because LLR is actually two processes, a wrapper and the LLR program, whereas AP27 doesn't use a wrapper so it's just one process.
If the app is listed as being "threaded", it's probably because it's linked to the multithreaded versions of the libraries. That's not needed (it's not actually a multithreaded app), but it won't hurt anything. It might slow down some system calls by an insignificant amount, but won't affect the calculation speed.

As far as I remember 32-bit CPU app was significantly slower then 64-bit so it wasn't enabled.
As for GPU app, it was Michael's decision to not send it to 32-bit systems although GPU app itself is 32-bit, motivating that number of such systems (32-bit OS and capable GPU with 2+ GB of video RAM) was very low.
I have also noticed that suspend-in-memory has been implemented differently to how it was done in LLR -- when an AP task is suspended the Linux command "ps" lists its state as "S" (interruptible sleep), whereas LLR shows up as "T" (stopped by job control). This difference makes no practical difference to me as a user, it was just unexpected.
Also ps lists the AP apps as being threaded, whereas LLR are not.
LLR is a standalone program which need a wrapper to be between it and Boinc. AP is a "native" (linked with Boinc libraries, could communicate with Boinc core directly). So some different approaches are used:
- When Boinc tell the LLR wrapper to pause, LLR has no way to pause calculations. So wrapper just freezes LLR process.
- When Boinc tell AP to pause, "native" program could indeed stop calculating and do only endless wait-for-events loop - check events state (was pause request cleared? was exit request received?); if no events, sleep for 1 second; check events again and so on. So you see it mostly in a sleep state.
- An extra thread in native app is automatically created by Boinc libraries to receive events from Boinc core. It runs small amount of code once per second or so, so you'll not see noticeable amount of CPU time spent in it.

Thanks for the clarification on the GPU apps, stream. I have 2 GT730 GPUs, a 2GB in a Win10 machine and a 1GB in a WinXP machine. I had hoped to upgrade one of the GPUs and "retire" the 1GB model so as to use both on AP27. Probably still will, I can keep one on GFN if I must. Just nice to have options but fully understand the whole XP thing. Maybe I'll see if I can come across a 64 bit copy of XP and do some testing. Used to have one somewhere..... |

or maybe Linux? (Not sure if Linux has drivers for the card that's in the XP box.).
CPU tasks runs faster under Linux than Windows, they seem to natively run faster PLUS there is a MUCH smaller operating system overhead in my experience (ie the difference between "elapsed" and "cpu" times is about ten times as big under Windows. I have tested this for Win 7 and Win 10, each is slower for Boinc CPU than Linux. But of course that is no help if Linux wont run your Gpu...

Which distro would you recommend? As the machine is for all intents and purposes a dedicated cruncher, I would like the lightest weight version possible. Ease of setup and use would be a MAJOR consideration as well. My only experience with Linux was about 8 years ago. I ran it under a dual-boot program called Wubi I believe. Wanted to speed up output on the old Virtual Prairie project and remember the learning curve being rather steep for me at the time and that was CPU only. |

Hi
Can anyone tell why AMD cards are so hopeless at this AP27?
Ross*
I wish I could tell you why, but I feel your pain. They are absolutely terrible at AP, when they are perhaps not so terrible at other projects.
Using my (slightly overclocked) 1060 3g as a benchmark, approximate completion times for select projects are:
AP27 2280 seconds
GFN19 5616
PPS-Sieve 602
On a (slightly overclocked) Rx 480
AP27 6370 (+179%)
GFN19 6540 (+16%)
PPS-Sieve 647 (+7%)
On a R9 290X (running stock clocks and -50mv)
AP27 5828 (+156%)
GFN19 6780 (+21%)
PPS-Sieve 734 (+22%)
Those numbers kind of speak for themselves. Kepler gpus may not be immune from this either:
On a GTX 770 running stock under macOS
AP27 8300 (+264%)
PPS-Sieve 567 (-6%, average of 2 units running concurrently).

This makes me feel much better about the run times on my GTX760 for AP. I was thinking it was either being CPU bound or not getting enough power from the power supply. Now I know it's normal.
Thanks!

That's bad because I have such a system. GTX670 GPU on an older WinXP32 gaming rig I didn't want to rebuild yet. Because I can't archive full power due to your limitation not sending a 32 bit capable app to a 32 bit system I will *not* participate in the race. |

On a 32-bit system, each process is given 4 GB of virtual memory to play with, which is separated into 2 GB of user space that the application can actually use at a time.
Not only does 32-bit have a hard limit for the amount of memory it can address, there's also another problem: your devices, like your video card and motherboard BIOS take up room in that same 4 GB space, which means the underlying operating system gets access to even less of your RAM.
Windows expert Mark Russinovich found that a desktop running 32-bit Windows with 4 GB of RAM and two 1 GB video cards only had 2.2 GB of RAM available for the operating system—so the bigger and better your video cards get, the less of that 4 GB will be accessible on a 32-bit system.

From a TeAm-mate of mine:
Sadly my 6950 does not have enough ram to run the program. I ran a test unit for primegrid just fine with only 1gb, but they limit the program to 1.5 for some reason.
Does AP27 really need 1.5GB VRAM?

Status:
After a bit more than 1 day:
Challenge: Wallis is Born
App: 11 (AP27)
(As of 2016-11-19 19:40:31 UTC)
42222 tasks have been sent out. [CPU/GPU/anonymous_platform: 8728 (21%) / 33460 (79%) / 34 (0%)]
Of those tasks that have been sent out:
3540 (8%) came back with some kind of an error. [417 (1%) / 3123 (7%) / 0 (0%)]
21336 (51%) have returned a successful result. [1357 (3%) / 19953 (47%) / 26 (0%)]
17349 (41%) are still in progress. [6956 (16%) / 10385 (25%) / 8 (0%)]
Of the tasks that have been returned successfully:
8159 (38%) are pending validation. [414 (2%) / 7736 (36%) / 9 (0%)]
13177 (62%) have been successfully validated. [943 (4%) / 12217 (57%) / 17 (0%)]
0 (0%) were invalid. [0 (0%) / 0 (0%) / 0 (0%)]
0 (0%) are inconclusive. [0 (0%) / 0 (0%) / 0 (0%)]
What a great start to the challenge! We sent out about ten times the normal amount of tasks in the first day, which is fairly typical for challenges.
What isn't typical at all are the results. So far, we've found 5 AP25s since yesterday, including one that was found just before the challenge started (but the double check WAS part of the challenge, so I'm counting it), and another one that's still in the pipeline. To put things in perspective, since we started the AP27 search in September, a total of five AP25s (including one AP26) were found -- the same number as have been found in the last day. I can't really account for why the challenge has been so prolific at producing AP discoveries.

I'm not up to speed to adequately understand the other post on what parts were or were not covered in the previous search. Could it be we're doing more of unsearched territory now? |

Slightly more, yes, but nowhere near enough to account for the sudden deluge of AP25 finds. When we started, we were doing 70% new work and 30 percent double checking. (6 out of 20 shifts were double checks). Right now we're doing 80% new work and 20% double checks (4 of 20). Furthermore, 4 of the 5 recent AP25s with in shift=640 tasks, and nothing at all has changed with those tasks.
It's probably just a statistical fluke.

What a great start to the challenge! We sent out about ten times the normal amount of tasks in the first day, which is fairly typical for challenges.
I am surprised, that number of pending units raise, regardless 10 times more WU sent. I was expected faster validation time.

For the challenge people are running the AP tasks on hardware that they normally wouldn't use for AP. Some of that hardware being slower CPUs that take a long time to run units.
Normally I run a GTX 1060 (40 minutes a task) and a GTX 760 (2.5 hours a task). Now I also have an i7-4790 (16 hours a task) an Athlon X4 635 (48 hours a task) and a Pentium dual core E5500 (also 48 hours a task) running for the challenge. So you would be waiting a long time for tasks to validate with slow hardware like that running.

Thats right. my two Phenom x4 9450 are over 52%. |

Celeron N2840 2 tasks 3.8 days :) (it normally does sieving).
Every little helps, as a certain unmentionable United Kingdom retail conglomerate keeps bleating. |
