GFN65536 - Solstice Challenge - 20-27th June 2015

Announced is a one week GFN65536 (Generalized Fermat Number Prime Search N=65536) challenge from the 20th until the 27th of June. I suggest we start at 12:00 UTC and end at 12:00 UTC.

Around the 21st of June, the Sun is at its most northerly declination (+23.5 degrees). This corresponds to the northern summer solstice and marks the longest day of the year for the northern hemisphere. In contrast, this is the date of the southern winter solstice and marks the shortest day of the year for the southern hemisphere.

The largest prime found in this sub-project so far is 3553248^65536+1 by Scott Brown on the 8th of April 2015. Search is currently completed to b=3,574,500. We expect 4.8 primes between here and b=4,000,000.
Source: http://yves.gallot.pagesperso-orange.fr/primes/stat.html

More about the Generalized Fermat Number 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=GFN65536:100:1:prpnet.primegrid.com:12003

The Genefer80 transform will be used exclusively at N=65536. Genefer automatically uses this transform so no need to do anything other than make sure the geneferexe=genefer64.exe (or genefer32.exe if your running 32 bit OS) line is uncommented in the master_prpclient.ini. Other geneferexe lines should be commented out as ocl and cuda are beyond their b-limits. Remember you also need to run the "install", "update" and "start" batch file for the appropriate number of cores on your PC. Give it a go before the challenge to iron out any problems.

Stats will be available 15 minutes after the start at the well known place here.

All previous PRPNet challenge stats can be found here.

Good luck!

So, uh, I kinda want to participate, but I'm a little confused. A couple quick questions:

1- Is it GFN (short), GFN WR, or neither? How do I set my preference pages accordingly?
2- Can you explain that code tweaking a bit further? Now, I have tinkered with the cc_config and app_config files, as well as moving files locally before, but in those cases, I knew what a I wanted and where to find it. This prpclient.ini file and those tags are unknown to me.
3- Do I need client restart, read config files, or just project update (or maybe even nothing at all)?

It is not a BOINC-Challenge! Forget about the BOINC-things lik cc_config et al.
You had to set up the PRPNet-Client and choose there in the client-configuration the GFN65536-server-port

#3! Though I don't expect that to last...

Interesting observation on the stats this morning, since there are so few current participants at the moment, it's one user per team. So why are some of the credit numbers different between the user stats and team stats for the same work?

My second computer's genefer64 && 32 bits are crashing right after the Using AVX(intel) Transform is written to the console.
CPU genefer works fine in boinc but not in PRPnet, using windows 7 64 bit. Any ideas what may cause it?

Also could we use gpus for this by any chance? :)

My second computer's genefer64 && 32 bits are crashing right after the Using AVX(intel) Transform is written to the console.
CPU genefer works fine in boinc but not in PRPnet, using windows 7 64 bit. Any ideas what may cause it?

Also could we use gpus for this by any chance? :)


GFN 32768 and GFN 65536 are well beyond the B range where anything other than the x87 transform can work. No chance whatsoever of a GPU version of Genefer working on current (or project future) GPUs.

Furthermore, the GPUs are less efficient on smaller Ns -- they spend proportionally more time setting up each calculation and less time actually calculating, so efficiency would be significantly lower even if running the GPU apps were possible.

Thanks for this info, as a current student it's something that I'll have to explore as it's pretty neat.

Out of interest what do people use as the machine ID for the PRP client? Does the client write checkpoints if so how often?

machineid differentiates clients using the same e-mail ID.
You can set it to anything you like. There is no wrong answer.
I set mine to give info to others about my machine, i.e. X61100HD7970 = X6 1100T AMD CPU & HD7970 AMD GPU
If you find a prime the machineid is stored with the prime on the server.
I started using BOINC Computer ID for my machineid but moved to something more tangible long term as Computer ID changes every time you have to reinstall the OS.

Looking at the genefer.ckpt file, seems to be re-written at least every minute.

#3! Though I don't expect that to last...

Interesting observation on the stats this morning, since there are so few current participants at the moment, it's one user per team. So why are some of the credit numbers different between the user stats and team stats for the same work?

1 Lumiukko 103 190,088 2 Ross* 86 158,727 3 Grebuloner 60 110,740


1 PrimeSearchTeam 103 190,087 2 Sicituradastra. 86 158,727 3 The_Knights_Who_Say_Ni! 60 110,739


I know it's just one silly point here and there, but I'm still curious.

I 've seen this too; no fact on my side;
I compute the number now ./. the number at start; the numbers come from the official stats pages at http://prpnet.primegrid.com:12003/
for workunits the results are equal between team and member
for score the results differ by 1 (but not at all user/team comparison);
about the cause I only can speculate; maybe some sort of rounding error or (not seen) summing of decimal places

Thanks Roger. Things are ticking along nicely. I'm not sure with the checkpoint file is located however I certainly know it is working when I close the command window using Ctrl + C. For the purpose of this challenge I have also used my Boinc ID= Speedy

Message 86382 - Posted: 24 Jun 2015 | 7:16:41 UTC

Form of prime we're searching is: b*65536+1. Lets take a closer look at the chance of prime.
The primes found are listed on the PRPNet server: http://prpnet.primegrid.com:12003/user_primes.html
and earlier ones on OEIS: https://oeis.org/A251597
In the graph below you'll see the b-gap between prime finds ranked by size of the gap with an exponential line of best fit.

Leading edge now ~3,733,118. Gap from the previous prime find ~179,870 and growing, shown as red in the graph.
Certainly looks like a big jump from b-gap 178,522 to 254,584 either side of the red column.
Maybe we'll find a prime before the b-gap grows to 254,584 and help fill in this distribution, i.e. b < 3,807,832.
Note that the current gap is ranked 39 out of 44, so 86% of gaps (found so far) are smaller than the current one.

Note, however, that it is expected that the typical gap size (i.e. the difference between consecutive b values such that b^65536+1 are prime) is expected to increase (quite slowly!) as we move towards higher and higher numbers.

What does the graph look like if you do not "sort" the columns? Is this increasing gap trend visible yet?

What does the graph look like if you do not "sort" the columns? Is this increasing gap trend visible yet?

See below graph of the gap size ranked by b, low to high, i.e. not sorted.

You can see on average for each prime, gap size increases by 980.
So yes, increasing gap trend is quite visible.
You can use this to correct the prior series.
Should get a distribution better fitting the exponential curve.

Pulling the data from Top 5000, I get an average gap of ~81000 and a std deviation of ~88000 which is in excellent agreement with a Poisson process (average = std dev).

It is possible to "hack" the search function on Caldwell's Top 5000 site so that you can link to a search query. A search like Description=.^65536+1, Comment=generalized fermat, OnList=verified, Number=200, Style=HTML gives all known GFN65536 primes, including the two we found in this challenge up to now.

3803826^65536+1 is prime!
Is shown on PRPNet server as PRP.

The other PRP on this port is also prime:
http://primes.utm.edu/primes/page.php?id=119309
3503138^65536+1 is prime!

Can the PRPNet server and PRPNet-Stats be changed to show them as prime rather than PRP?

For all of the PRPNet projects, it appears that the designation PRP or Prime is rather arbitrary. The user client might use a program (like genefer) which only proves the number is a probable prime. But in each of those cases, a check has been done (later) with another program which proves primality in a non-deterministic way. So all "PRP" here are really prime.

Maybe "PRP" indicates that the user had a desirable configuration where he prevented expensive extra testing from being performed locally before submitting the find to the server!

I see no subproject where we do not perform a full primality test eventually.

(Of course, if we found a PRP which turned out not to be prime, that would be sensational.)

Why was PRPNet called PRPNet?

This is exactly what happens in the case of the GFN primes. Genefer is only a PRP test. If other prime finding programs are also uncommented (i.e., LLR, PFGW), then one of those tests are run on a PRP find. Otherwise, the PRP is returned to the server and internal prime verification is done.

Leaving the other tests on for the small GFN ports is not really that "expensive" in extra testing (e.g., the GFN65536 port would primality test a PRP in about the same time one can do a PPSE test on BOINC). For the two larger ports (n=18 and n=19), the extra tests do take substantially extra time.
