121 - Happy St Patrick's Equinox Challenge - 16-21 March

Announced is a challenge at the 121 prime search project from the 16th till 21st of March. I suggest we start at 12:00 UTC and end at 12:00 UTC.

For this Challenge we're celebrating Happiness:
Lyrics: (Because I'm happy) / Clap along if you feel like a room without a roof / (Because I'm happy) / Clap along if you feel like happiness is the truth…
The International Day of Happiness is celebrated throughout the world on the 20th of March!

and St Patrick's Day:
St. Patrick’s Day occurs annually on March 17 in observance of the death of St. Patrick, the patron saint of Ireland. What began as a religious feast day in the 17th century has evolved into a variety of festivals across the globe celebrating Irish culture with parades, special foods, music, dancing, and a whole lot of green.

and the March equinox:
March 20 - March Equinox. The March equinox occurs at 10:29 UTC. The Sun will shine directly on the equator and there will be nearly equal amounts of day and night throughout the world. This is also the first day of spring (vernal equinox) in the Northern Hemisphere and the first day of fall (autumnal equinox) in the Southern Hemisphere.

More about the 27121 prime search can be found here. News and infos about the PRPNet client can be found here.

To take part, you have to activate the following lines in prpclient.ini:

server=121:100:1:prpnet.primegrid.com:12001

Stats will be available at the well known place here.

All previous PRPNet challenge stats can be found here.

Good luck!

bugfix:
1) link in stats page points now to this thread
2) sum line only for users, because users may not in any team (prevent confusion)

Less than 30 minutes until the Challenge start.
I am heading to Rosie O'Grady's tomorrow night for St Patricks Day. So great being on a Friday night.

Due to celebrations on my own behalf I missed the start.
But everything seems to be going well ...
Happy racing!

I think that if you're not sure if your computer is reliable that you should absolutely, positively, not be running PRPNet. Run BOINC tasks instead so that your results can be verified.

One good way to check reliability is to turn off PRPNet and run one of those numbers manually through LLR twice. If you get different results, your machine needs to be fixed. If the results are the same, you're good. Do this test under the same conditions as you are running right now. I.e., if you have all cores running right now, do the test with all cores running. You can even run the same test individually on each core and make sure each instance returns the same residue.

Please do not PM me with support questions. They will usually go unanswered. Ask on the forums instead. Thank you!

Thanks for the advice. I have been with PrimeGrid for some time now so I am aware as to the demands on the host machines. I actually only crunch on a couple of cores at a time.

I run BOINC on this machine unless there is a PRPNet challenge active. I was fortunate enough to find a megaprime using this host, but that was a relatively long time ago and as a i5-3570K it looks a little long in the tooth. Once the challenge is over I'll go back to ESP WUs. If I start throwing lots of errors on LLR WUs under BOINC then I will stop using this host on PRPNet.

What I should have asked is...
Does anyone else see this output: "Disregard last error. Result is reproducible and thus not a hardware problem."

I'm running two instances and haven't seen anything untoward on the other process.

Thanks,
Peter

You're near the maximum size candidate that FFT size can handle. If you ran it with -oFFT_Increment=1 then I don't think there would be any errors at all. Our BOINC validator ignores an error when it's followed by the "Disregard this error" line. In fact the program might switch to the next larger FFT all by itself after six or so "errors".

I can't get prp to work on linux 64 bit on Debian 8 Jessie. I put a message on the forum on another board but maybe someone here can look at it and give me some advise.

After looking on the web and hitting my head against the wall for a couple of hours I deleted everything so I need to start from scratch.

For a bit of background, the + side of PRPNet 121 and 27 projects are double checked on BOINC, although it is far behind. Currently:
k=121 up to n=3,049,908 on BOINC, n=7,388,708 on PRPNet (+ side)
k=27 up to n=3,321,956 on BOINC, n=6,427,079 on PRPNet (+ side)
121 and 27 candidates are regularly uploaded from the latest PPS Sieve files for both the plus and minus sides.
PPS Sieve is doing k's 5-9999 on both the plus and minus sides. k=3 is sieved separately.

And as I said during the last 121 challenge, since 121 is a square not divisible by 3, the expression 121*2^n ± 1 taken modulo 3 is 1*(-1)^n ± 1.

So for the plus form, only even n are possible (otherwise we have 0 modulo 3). That makes it a Generalized Fermat Number:

121*2^n + 1 = (11*2^(n/2))^2 + 1

So if we find any prime in the plus series, it will enter the GFN Top 20. It would go into the Proth Top 20 as well.

What about a hit in the minus series, 121*2^n - 1? I do not think it would be in any of Caldwell's Top 20s?

Any find of this size will go to the general Top 40, though. Near position 31.

We are now past equinox (10:29 today), and the daylight will favor the northern hemisphere, home to close to 90% of the planet's population, until 22 September. /JeppeSN

The Challenge has ended. Congratulation to Grebuloner and The_Knights_Who_Say_Ni!

The top of the challenge rankings is as follows:

top users 1 Grebuloner 28,493,430 2 Williamd007 9,816,126 3 Lumiukko 8,122,076 4 zunewantan 5,797,882 5 Dingo 5,444,466 top teams 1 The_Knights_Who_Say_Ni! 38,309,556 2 BOINC@AUSTRALIA 10,263,242 3 Aggie_The_Pew 9,209,740 4 PrimeSearchTeam 8,122,076 5 BOINC@Latvia 5,062,137

Collectively 2,030 WUs were done by 33 competitors from 17 Teams and the leading edge advanced from 7,368,530 to past 7,430,120 on both the plus and minus sides.

Well done to everyone who participated. See you in the April Primorial Challenge!
