Wieferich - Tolkien Week Challenge - 19-26 September

Announced is a challenge at WFS (Wieferich prime search) from 19th until 26th of September. I suggest we start at 12:00 UTC and end at 12:00 UTC one week later.

Hobbit Day is the birthday of the hobbits Bilbo and Frodo Baggins, two fictional characters in J. R. R. Tolkien's popular set of books The Hobbit and The Lord of the Rings. In the books both Bilbo and Frodo were said to be born on September 22nd, but of different years. Bilbo was born in the year of 2890 and Frodo in the year of 2968 in the Third Age (1290 and 1368 respectively in Shire-Reckoning.) Tolkien Week is the week containing Hobbit Day.

The Fellowship of the Ring opened with a celebration of Bilbo's birthday. It was a large party with food, fireworks, dancing and much merriment. Some Tolkien fans celebrate with having parties and feasts emulating the hobbit's parties. Other fans celebrate by simply going barefooted in honour of the hobbits, who don't wear shoes.

More about Wieferich prime search can be found here. We're currently at 4.3e17. Goal will be to get to 5.0e17, based on the rate of previous WFS challenges. 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=WIEFERICH:100:1:prpnet.primegrid.com:13000

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 at the well known place here.

All previous PRPNet challenge stats can be found here.

Good luck!

I'm always amazed that you would promote a Wieferich challenge to newbies and never ever mention the CRITICAL need of a WWW.INI file! If they try running without it, they get terrible thruput, give up, and go else where.

For HD7970 GPU I use blocks=1024 and threads=6 with 5 WU lots,
i.e. in wwww.ini I would set:
blocks=1024
threads=6
And in the master_prpclient.ini I would set:
server=WIEFERICH:100:5:prpnet.mine.nu:13000
Then run 1-single-update-prpclient-ini.bat

For other people these settings might be different because I have a 6 core CPU, and setting for optimal blocks will be different with each model of GPU.
Try different blocks, see what performance is acceptable with screen lag and allows higher throughput of WU's per unit time.

Below are my notes from such testing in September 2012:

===========================================================
Using blocks=512, threads=7 works well in Wieferich with 764 Work Units in 11:32:46. This is average one Work Unit in 54.4 seconds.

Aim is to check that these are optimal values.

Search space:
threads=8, blocks=256, 3 units=2:46, average=55.3
threads=7, blocks=256, 3 units=2:47, average=55.6
threads=6, blocks=256, 3 units=2:59, average=59.6

threads=8, blocks=2048, 3 units=2:40, average=53.3
threads=8, blocks=1024, 3 units=2:35, average=51.6
threads=8, blocks=512, 3 units=2:39, average=53
threads=7, blocks=2048, 3 units=2:38, average=52.6
threads=7, blocks=1024, 3 units=2:35, average=51.6
threads=7, blocks=512, 3 units=2:43, average=54.4
threads=6, blocks=2048, 3 units=2:38, average=52.6
threads=6, blocks=1024, 3 units=2:35, average=51.6
threads=6, blocks=512, 3 units=2:36, average=52

1024 blocks look good. Do long tests with 6-8 threads.

Using blocks=1024, threads=6 works well in Wieferich with 335 Work Units in 4:58:32. This is average one Work Unit in 53.4 seconds.

Using blocks=1024, threads=7 works well in Wieferich with 306 Work Units in 4:33:56. This is average one Work Unit in 53.7 seconds.

Using blocks=1024, threads=8 works well in Wieferich with 824 Work Units in 12:20:21. This is average one Work Unit in 53.9 seconds.
GPU 93%, CPU 96%.

Using blocks=1024, threads=5 works well in Wieferich with 110 Work Units in 1:30:04. This is average one Work Unit in 49.1 seconds.
GPU 93%, CPU 88%. 5 WU lots.

Using blocks=1024, threads=4 didn't work well in Wieferich with 5 Work Units in 0:06:24. This is average one Work Unit in 76.8 seconds.
GPU 80%, CPU 73%. 5 WU lots.

Using blocks=1024, threads=6 works well in Wieferich with 570 Work Units in 7:49:30. This is average one Work Unit in 49.4 seconds.
GPU 93%, CPU 97%. 5 WU lots.

So 5 threads is best. Increase to 10 WU lots.

Using blocks=1024, threads=5 works well in Wieferich with 800 Work Units in 11:02:33. This is average one Work Unit in 49.6 seconds.
GPU 93%, CPU 88%. 10 WU lots.

Using blocks=1024, threads=6 works well in Wieferich with 120 Work Units in 1:38:44. This is average one Work Unit in 49.3 seconds.
GPU 82%, CPU 99%. 10 WU lots.

Using blocks=1024, threads=5 works well in Wieferich with 470 Work Units in 6:30:55. This is average one Work Unit in 49.9 seconds.
GPU 82%, CPU 85%. 5 WU lots.

Using blocks=1024, threads=5 works well in Wieferich with 70 Work Units in 0:59:31. This is average one Work Unit in 51.0 seconds.
GPU 77%, CPU 89%. 10 WU lots.

Using blocks=1024, threads=6 works well in Wieferich with 105 Work Units in 1:27:27. This is average one Work Unit in 49.9 seconds.
5 WU lots.

=> Work load is increasing with time.
=> GPU/CPU load varies. Idea is to keep GPU load high.
=> 6 threads is currently quicker but needs recheck periodically.
=> 5 or 10 WU not much difference. Both way better than 1 WU.

Now I am ready to rule Middle Earth.

Today zunewantan found the near-hit 437137110519565847 (+1 -981 p).

Do not forget that if you have PARI/GP, the function:

checkWieferich(p) = { if(!isprime(p)||p==2,return("no, p is not an odd prime")); plusOrMinus = kronecker(2,p); result = centerlift(Mod(2,p^2)^((p-1)/2)); result = (result-plusOrMinus)/p; Strprintf("%d (%+d %+d p)", p, plusOrMinus, result) }

will let you check really quickly if any find or near-find in the Wieferich (WFS) subproject is valid.

How many near-finds will be made during this challenge...?

Someone might want to name those finds after characters from Tolkien's universe.

I have an issue running WFS and WSS with my AMD 7970. If I run it at 100% it will eventually crash the driver. It runs cool, under 60C, and it works for weeks running GFN. I’ve tested it with Linux and windows 7 and 10 using old/new/beta drivers. The only way to make it work is to run only 3 threads/4096 blocks and keep the GPU utilization =< 90%.

It still does one unit every 62 seconds but when its running full boar I can get 50-54 every second.

Is anyone else experiencing this issue?

I have an issue running WFS and WSS with my AMD 7970. If I run it at 100% it will eventually crash the driver. It runs cool, under 60C, and it works for weeks running GFN. I’ve tested it with Linux and windows 7 and 10 using old/new/beta drivers. The only way to make it work is to run only 3 threads/4096 blocks and keep the GPU utilization =< 90%.

It still does one unit every 62 seconds but when its running full boar I can get 50-54 every second.

Is anyone else experiencing this issue?


How much memory usage are you observing? The WFS units are fairly large so I am wondering if 4 threads with that block size is causing some issues?

Getting my hosts up and running early (as the local start time is just way too early for me to get up for), and ran into a rather interesting error that I hope someone can help me out with.

Since I just upgraded my main machine to a 980 ti, I took my old 580 and swapped it into a cruncher that had been running a 480 without any issues and updated the drivers to the latest version (355.82-same as on my 980ti host which does NOT have this problem). I started up the client and was met with an error message window titled "pfgw32.exe" and "could not start due to MSCVR110.dll missing from the computer." Okay, uninstalled/reinstalled the relevant MS redistributable (2012), no joy.

Then I wondered: why is Wieferich starting pfgw32? It's commented out of the config file. I tried uncommenting it and pfgw64 separately with no change.

So...I deleted pfgw32 from the client directory, and now it runs, but the first line in the program window is that it wasn't found.

Is this bad, okay or something else?

Did you try to run Wieferich with CPU?
What "wwwwexe="-lines are commented out at prpclient.ini, or is there a typo at executable name?

I also have AMD HD7970, mine is a Ghz edition
I am getting good CPU usage ~98-99%
GPU Load 92%
wwwwcl c2.1.9
Catalyst Version 14.12
First 5 WU's in 4min 31 sec => 54.2 sec per WU
First 75 WU's in 1hr 7 min 57 sec => 54.4 sec per WU
As number tested gets larger, WU time gets longer. Probably with the log of the size or something.

wwww.ini
blocks=1024
threads=6

Note I started with wwwwcl.exe and that was crashing. Then I changed over to wwwwcl64.exe

Lumiukko


the wwwwexe is set to wwwwcl64.exe, all others commented. I checked for typos, but couldn't find any, even copied pfgw32 from my cpu prpnet directory and the error was there. Just tried going the cpu route (wwww.exe) and that worked without issue.

I have managed to fix the problem...sorta. I have 2 PRPnet directories, one for cpu, the other for gpu. Aside from project config settings, they are cut-and-paste copies of each other. I set up the cpu folder to run wwww on the gpu, and the error/message is gone. Something must have gone nutty there. I'll work on that later after the challenge.

OK, this was my bad I totally forgot that PRPnet makes new folders with the slots, I got that down just fine - sorry for posting about it so quickly. My question now would be: What is the setting which affects CPU usage? My memory is sitting at 80% usage, while that may be high the CPU usage is at 100% and the gpus are each at 50%. So the memory has a little wiggle room, but I would prefer the GPU's to be at full load.

I am using wwwwcl64 and blocks=1024 threads=6

I really wouldn't like to be potentially missing time if possible :)

CPU utilization is controlled by the key

threads=N

Each client will use N+1 CPU cores (1 core is used with gpu)

What CPU You run? With Your settings single client tries to utilize 7 CPU cores. I guess it is not the best choice for multiple GPU config.

About low GPU load: it is possible to run several clients on a single GPU (keys "device=" in wwww.ini must be identical for these clients). Unfortunately, each client will "eat" CPU cores. For multiple GPU config I would prefer to run single client on single GPU and pay no attention the low GPU load. Additionally try to increase "blocks=".



/UPD
The statement "N threads utilizes N+1 processor cores" is not exactly correct.

It's almost right for NVidia gpu's.
So, GTX570 with threads=2 on core2quad-cpu uses 65-72% of cpu (more than 2 and less than 3 cores).
GTX980 with threads=5 on i7-2600K (8 HT cores) uses 63-74% (5-6 cores).

And ATI gpu's fairly utilize the number of cpu cores specified with "threads" parameter.

If you think you have good settings of threads and blocks please post them for others to see.
Ultimately a table of settings would make it much easier for folks to get started in Wieferich.
Optimal settings may be different for different GPU/CPU combinations.
- GPU AMD HD7970
- CPU AMD X6 1100T
- threads=6, blocks=1024

GPU: GTX 980 ti
CPU: i7 3930k
threads=16, blocks=6144, ~27 secs, 80-90% GPU load, 80% CPU load.

GPU: HD7950
CPU: i7 3930k (OC)
threads=7, blocks=1536, ~105 secs, (2 tasks running simultaneously), 95% GPU load, 15% CPU load/task

GPU: HD7950
CPU: i7 920
threads=7, blocks=1536, ~58 secs, 90% GPU load, 60% CPU load

GPU: GTX 580
CPU: i5 3570 (OC)
threads=8, blocks=1536, ~55 secs, 90% GPU load, 85% CPU load

I find it rather interesting that the AMD cards use fewer CPU resources than the Nvidia ones. I've also found that getting the GPU above 90% is rather hard to do and provides rather minimal gains (that is, less than the theoretical ~11% decrease in run time).

If prpclient refuses to start after this error, just look for wwww.log and remove it, and try again. You may want to remove any files in the prpclient-N directory dated later than when you installed, just for cleanliness.

On the other topic, the o/s is involved also in the issue of CPU usage for wwwwcl. On linux to keep the GPU fully fed, it takes about 1.5 (out of 4) i7 cores. This is a driver issue on NVidia, and isn't fixable without impairing GPU throughput.

If the client is running under Windows check the permission rights to the client directory. Set "Full control" for Users group.

First two days of the challenge completed.
Leading edge has now passed 4.5e17.

Now up to 30 users. In the previous January WFS challenge we had 58.
Top user currently zunewantan with Scott_Brown close behind. Places 6-11 a bit of a traffic jam.
Aggie_The_Pew well in front in the Team rankings.

We seem to be inside a big gap between (consecutive) near-hits. Still no near-hits since zunewantan's one, approx. 4.37e17, mentioned (by me) earlier in the thread, and the leading edge is now near 4.63e17.

I still think near-hits will be found during the challenge.

We seem to be inside a big gap between (consecutive) near-hits. Still no near-hits since zunewantan's one, approx. 4.37e17, mentioned (by me) earlier in the thread, and the leading edge is now near 4.63e17.

I still think near-hits will be found during the challenge.

/JeppeSN


you were right. we have a near-hit now. congratulations to Honza, who, oddly enough, is not listed on user stats

Edit: looks like it's an old find.


Sorry for confusion; it was the well known bug; log shows me an invalid/incomplete download of the user find html page; next step will be to prevent inserting this into stats and/or to get the cause of the invalid/incomplete download

2.5 days left of the Challenge. Will a near find make a showing?

“All that is gold does not glitter,
Not all those who wander are lost;
The old that is strong does not wither,
Deep roots are not reached by the frost.

From the ashes a fire shall be woken,
A light from the shadows shall spring;
Renewed shall be blade that was broken,
The crownless again shall be king.”

Just so everyone's aware, I have a meeting with the Elf council in the morning to see if we can fix this no near-find issue. They are very sensible. I expect they will resolve the issue immediately.

Still no near finds.

Back in the January challenge (Wieferich Water-carrier) it took a while to find the first near-hit, and I wrote a post comparing the gap between near-finds to previous gaps.

Here are all known 59-bit near-finds:

The gap from January is between 3.38e17 and 3.64e17 above

How long will the current gap turn out to be? Leading edge is near 4.76e17 right now.

Note the January gap was closed during the first days of the last WFS challenge.
We had 11 near finds in that challenge for 630,699 WUs, i.e. 1 in 57,336 WUs.
So far we've done 347,618 WUs for zero near finds.

Completed edge now at 4.56e17
Leading edge at 4.77e17

4.5 hours left. That ring's got to be around here somewhere...

Challenge Stats are final. Congratulation to zunewantan and Aggie_The_Pew!
The top of the challenge rankings is as follows:

top users 1 zunewantan 77,877,000 2 Scott_Brown 58,817,000 3 Grebuloner 46,580,000 4 zlodeck 32,149,000 5 brinktastee 26,160,000 top teams 1 Aggie_The_Pew 127,774,000 2 Duke_University 58,816,000 3 The_Knights_Who_Say_Ni! 47,813,000 4 Russia 32,149,000 5 PrimeSearchTeam 13,350,000

Collectively we've done 355,882 WUs, had 31 competitors from 14 Teams and advanced the Wieferich leading edge past 4.79e17. Unfortunately no near-finds were recorded during the challenge.

9.2e18 is the upper-bound the current software can search to, so we've now done 5.2% of that range.

Remember to make a suggestion at the 2015 PRPNet Challenges - Discussion and Dates thread.

Congratulations to everyone who participated!

I got a near-WFS today... Very odd that none were found during the challenge.

Is this one of the biggest gaps between WFS near-finds we've had?

|A|/p = 8.53e-17
It is the nearest one since 2014 July 14 (brinktastee), or longer is we consider |A|/p.

If no near-hits are found between zunewantan's find from Sep 17 and this, it would be the greatest gap, I think.

Strange that a near-hit is found a couple of days before the challenge, and another one on the day after the challenge, but nothing during the challenge.

In fact it looks like this is the smallest |A|/p ever; we have never been under 1e-16 before. /JeppeSN

If you have a nice idea for making such a graph, it would be interesting to see the result if you implemented it. /JeppeSN

Message 88698 - Posted: 4 Oct 2015 | 21:30:04 UTC - in response to Message 88480.

In the week following 1998golfer's record-near find above, zunewantan found two (less impressive) near-hits (488905347903024827 and 492035424267718399). So the gap from the challenge week was unusual.

(Certainly nothing "unfortunate"/"malign" happens during challenges which makes us miss the finds there?)

Continuing my list from above:

400159289776556689 (+1 +313 p) 401155495743783463 (+1 -429 p) 412931953717078981 (-1 +284 p) 413381850033153019 (-1 +689 p) 427662615581374741 (-1 +624 p) 437137110519565847 (+1 -981 p) 480637248454682153 (+1 -41 p) 488905347903024827 (-1 +881 p) 492035424267718399 (+1 +615 p)
