Wieferich Water-carrier - 20-27 January 2015

Announced is a challenge at WFS (Wieferich prime search) from when the sun enters Aquarius (Sun's longitude reaches 300°) until 1 week later, i.e. from January 20th 09:37:19 UTC until 27th 09:37:19 UTC.

Aquarius is the eleventh astrological sign in the Zodiac, originating from the constellation Aquarius. The symbol of the water-bearer is based on Hyas, who was killed by wild beasts while fetching water from the river. Individuals born under the sign of Aquarius are often quirky and unconventional. Sometimes their eccentricities are obvious -- they may have an unusual sense of humor, or have interests that others do not. Other times, Aquarians will have very small, quirky and sometimes amusing eccentricities which only become apparent as one gets to know them.

More about Wieferich 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=WIEFERICH:100:1:prpnet.primegrid.com:13000

We're currently at 3.3e17. Goal will be to get to 4.0e17.
Stats will be available at the well known place here.

All previous PRPNet challenge stats can be found here.

Good luck!

Cool.

For the usual naïve conjecture on the distribution of primes with the Wieferich property, the number of such primes in the interval from A to B is (log log B)-(log log A) = log((log B)/(log A)). So in the interval [3.3e17, 4.0e17] there should be 0.00476 new Wieferichs. The number of near-Wieferichs (by our definition) is 2000 times that, so we are going to find 9.52 new near-hits.

4.0e17 was also the limit that "Zeta-Flux" claims to have searched to already. However he says he did not get (entirely) correct results.

The first Wieferich prime, 1093, was found by Meißner in 1913. The second one, 3511, was found by Beeger in 1922. Will 2015 be the year the third Wieferich prime is found?

We are currently searching 59-bit numbers. We go on to 60-bit numbers when we hit 5.7646e17. In last September challenge thread I wrote a post where I presented a picture showing the size of Wieferich primes compared to Mersenne primes.

Thanks in advance!


The behavior of "BETWEEN" can vary from DB to DB with regards to whether the comparison is inclusive or exclusive, i.e., whether the tests are "<" and ">" or "<=" and ">=". With MySQL, the tests are "<=" and ">=".

For PrimeGrid's challenge code, I usually use Start <= datestamp < End. The start test is inclusive while the end test is exclusive. Therefore, I usually spell out the tests explicitly. I could use "BETWEEN" if I used "End-1". (That's not valid SQL, of course, but you get the idea: I don't use BETWEEN.)

Finally, the MySQL manual recommends casting the date string explicitly to a DATETIME. If you're not getting the results you expect, it's probably interpreting the string as a string and not automatically converting it to a timestamp. Also, if "<date_field>" is a DATE rather than a DATETIME, try casting that to a DATETIME too.

I will try "between", the planned behaviour is "<=" and ">=".

I tried experimenting with that syntax, and I can't get it to fail even without casting. Were you just asking if that would work? Or were you having a problem?

If you're having a problem, the next thing I'd check is that the date field in the table is actually a SQL timestamp rather than an integer containing a unix timestamp. Most (but not all!) BOINC timestamps are unix timestamps, so we have to always use from_unixtime() or unix_timestamp().

What is the maximum number of Wieferich work units that can be requested at once by a single PRPNet instance? I *think* at one time it was 25, but I may be mis-remembering. Also, at one point there was a bug in prpclient such that if you requested exactly the maximum, then when they were returned, credit for one of them went "missing". Has that been fixed? Could have been a while ago...

I usually stick to requesting something like 10 at a time per instance which seems to work fine and provides a decent buffer and network efficiency.

Looking forward to the challenge.

For Wieferich, the limit is 25. Each port has its own limit.

I do not recall if the problem you refer to has been fixed. Iain or Mark may know. (And it's possible a search of the forums will reveal the answer too.)

The thread about one WU being forgotten when requesting the max number of WU at a time, is here: Missing Workunits. I could not find any later post claiming the bug to be fixed (maybe I searched for the wrong words), so presumably the problem is still there. Several places it is recommended to request only 20 work units, not 25. /JeppeSN

And the challenge is running!

It appears that this year's Aquarius period will contain two new moons. The first of them is in less than three hours, at 13:14 UTC.

Normally the Chinese new year will be at the new moon of Aquarius. This time it will be at the second of the two new moons (which is closer to the "center" of Aquarius). Not surprisingly, this year has been a Chinese leap year (13-months year). The month that was "duplicated" was the 9th month (somewhat unusual).

And the Vietnamese new year, Tết, typically matches the Chinese new year, though apparently on rare occasions they can differ due to the time zone difference between Hanoi and Beijing. Though not this year. And we've got almost a month to go either way. Hopefully we'll productively crunch in the meantime. :-)

There was an attempt made to add an LLR-style residue to WWWW, so that two results could be compared together. Thus, a checksum was added. Unfortunately, the checksum is usually zero, so it's not terribly useful for double checks.

Once in a while you get a useful checksum (non-zero), but not very often.

Lately I'm getting non-zero checksums on every unit. GPU problem?

Then I guess it's working as intended. That was what we wanted the checksums to be. Mark (Rogue) is probably the only one who could tell you why it usually produces zeroes.

It was getting zero checksums on every client until the last hour. Then I tried to return results on shut down clients and started up too many of them (but not out of GPU memory). Checkums on every client were non-zero.

After I shut everything down and started one again, the checksums came out zero. Example:

How is that checksum calculated?

When I run the CPU version of the program, wwww.exe, the upper 32 bits of the checksum appear to be always 00000000, while the lower 32 bits seem "random" (like a good hash value), for example e805cb1f.

@Roger, I was just wondering if you could put the team name beside the individual somewhere or if that was even possible in the stats? Not a big deal just a suggestion.

this is impossible, because a user can change a team during race and the correlation between user and team isnt saved (if it is published on workunit-base I will have a look for coming up challenges)

Edit: in worst case you have 3 clients with team-id set to a team an 1 client without - in my stats 4 clients crunch for the user and 3 for the team but which team is related to the user: the 3-client-team, the one-client-non-team ...
a lot of problems comming up if I think further ...sorry seems not a good idea to me, as of now (could change later ;-) )

Going back to the max cache issue, as it gets its cache-worth (in my case 16) all at once, it appears to deplete what it's got then get all at once, rather than keeping it topped up. Not as good for outages IMO.

Yes, indeed, but asking brings up ideas, solutions or -unfortunately in this case- causes why not

so keep on asking
there are only stupid answers, not questions!

This is the way PRPClient is designed, there is not RRI (Report result immediately) feature.

If we had RRI, this would not solve whole of the problem in case of server outage/internet connection - PRPClient would try to return a result and waiting for the server to response.
This would need a bit of redesign of PRPClient I guess, errortimeout would need to be shorter etc.

On the other hand, I wonder when there was last unscheduled PRPNet outage...

The checksum was supposed to be a sum of remainders for the range being tested, but I never put a lot of time into getting it to work correctly.

this is impossible, because a user can change a team during race and the correlation between user and team isnt saved (if it is published on workunit-base I will have a look for coming up challenges)

Edit: in worst case you have 3 clients with team-id set to a team an 1 client without - in my stats 4 clients crunch for the user and 3 for the team but which team is related to the user: the 3-client-team, the one-client-non-team ...
a lot of problems comming up if I think further ...sorry seems not a good idea to me, as of now (could change later ;-) )


Not sure if it would be interesting, and also not sure if it would be technically possible, but maybe you could have a third table, in addition to "user stats" and "team stats", where you had "unique user/team combination stats". So if UserA had contributed to both CoolTeam and NationalTeam, this user's work would be split up in two rows, one row with (UserA, CoolTeam), and another row with (UserA, NationalTeam).

You should probably allow the "null team" as well, so (UserA, ) would be present if that user returned finished work that was not affiliated to any team.

Zero checksum together with halved execution time is very, very suspicious...

Halved execution time was because too many clients were running.
EDIT: This is for a GTX 760 in a PCIE v2.0 16-lane slot.
161 seconds = 1 client running, 15 Mp/sec throughput
230 seconds = 4 clients running, aggregate throughput of 45 Mp/sec, GPU is saturated
adding more clients beyond 4 does not raise the throughput

We finally found a near-Wieferich:

364420310115392591 (+1 +876 p)


If it turns out this is the next one after 338526053161351871 (which was found before the challenge, see above), we started our competition in a location within the greatest "hole" between consecutive near-finds. The previous hole record was the gap between 275873669630980061 and 290151872645732323.

Congratulations to Grebuloner.

Thanks Stream... It worked!

Hard to believe that this program eats all four cores on my i5-4690 just to feed my 770.
I'm getting 37 Mp/sec and completing tests in 72 seconds or less.

Question regarding near finds...

The DEFAULT wwwwcl64 for special/near finds is "100" ... ( type "wwwwcl64 -h")

How is it that near finds such as the two just found are being reported if they exceed 100?

My guess is the parent executable (prpclient) calls wwwwcl and uses 1000. On linux with the ps command you can see this option being set:

The number of near-finds in this event is now FOUR.

I see that new work units have been "loaded" onto the port. So keep up the good work.

I am trying to jump into this challenge, but when I start my prpclient,
I get the following error:

"VCOMP110.DLL missing"

MSVC2012 Redistributable: http://www.microsoft.com/en-us/download/details.aspx?id=30679

Download and install correct file: x86 for 32-bit system, x64 for 64-bit. (You may have to install both packages on 64-bit system if you want to run a mix of 32-bit and 64-bit programs).



Thanks Stream... It worked!

Hard to believe that this program eats all four cores on my i5-4690 just to feed my 770.
I'm getting 37 Mp/sec and completing tests in 72 seconds or less.

You must be doing some wrong. I get 45 Mp/sec from a slightly oc'd GTX 760 fed by i7-920 @ 2.74 GHz.

Would be helpful to post your wwww.ini settings and how many PRPNet instances are you running.
And drivers version as well - it may impact perfomance as well.

I get approx 46 Mp/sec on my 760 fed by i5-2500k @ 4.5Ghz. CPU usage is ~90% and GPU usage is ~95%
4 threads 8192 blocks, 2 instances.

Maybe 45 Mp/sec is overstated, as it doesn't account for serialing of workunits among clients that may be taking place.

My average time of 55 seconds per workunit is a better metric.

My specs are:
- GTX 760 factory o/c, "graphics clock 1176 MHz", "memory transfer rate 6008 MHz"
- NVIDIA driver 372.19 for Linux x86_64
- core i7-920 @ 2.74 GHz
- PCIE 2.0 motherboard (GTX 760 is capable of PCIE 3.0)
- running 2 displays off the GTX 760
- 4 prpnet clients running simultaneously

wieferich_threads=2
wieferich_blocks=6144

Setting the blocks to 8192 improves throughput by 1% but the display lags badly.

Best throughput happens when each client is confined to a distinct physical core, using both hyperthreads of the same core.

Hi
As I am new to this particular type of tasks , could anyone tell me what are the best setups to run.
some observations I have made:
ATI cards running wwwwcl64 run at 2.1m to 4m p/secs and sometimes use the cpu. Average time seems to be 40 mins. only 1 card takes the load, 2rd card does nothing. Is this right?

NV cards run at 490k> to 690k p/sec average time 83 minutes both cards working [wwwwcl64] Why so slow? no cpu time ?

I have started one box [5960 8 core] on cpu tasks and they take 40 mins
8 tasks in 40mins, against 4 NV tasks in 83 mins. what am I missing?

How many instances should I be running on any one GPU [ATI or NV]?

also when I try to run wwwwcl64 on win 8.1 box it comes up with the 0xc0000076 bug , why?
its fine on Win 7 Boxes.
The NV cards are 780ti or Titan z all good DP cards
Cheers

Hi
As I am new to this particular type of tasks , could anyone tell me what are the best setups to run.
some observations I have made:
ATI cards running wwwwcl64 run at 2.1m to 4m p/secs and sometimes use the cpu. Average time seems to be 40 mins. only 1 card takes the load, 2rd card does nothing. Is this right?

NV cards run at 490k> to 690k p/sec average time 83 minutes both cards working [wwwwcl64] Why so slow? no cpu time ?

I have started one box [5960 8 core] on cpu tasks and they take 40 mins
8 tasks in 40mins, against 4 NV tasks in 83 mins. what am I missing?

How many instances should I be running on any one GPU [ATI or NV]?

also when I try to run wwwwcl64 on win 8.1 box it comes up with the 0xc0000076 bug , why?
its fine on Win 7 Boxes.
The NV cards are 780ti or Titan z all good DP cards
Cheers

My guess is that you are running without a wwww.ini file created to manage the application (Wieferich and Wall-Sun-Sun are the only ones on PRPnet that need this). Here is a copy of mine running a single GTX 650 Ti card in 64-bit Vista:


// The settings in this file are used to set various values that cannot be set via command line // switches. Except where noted, the command line switches will override values specified here. // platform and device specify the platform and device to run on platform=0 device=0 // blocks is a multiplier used to set workgroup size //blocks=1000 // threads is the number of concurrent threads to execute //threads=2 // minprime and maxprime set the range to be searched //minprime= //maxprime= // These settings will override the default settings for blocks and threads and they will // also override the command line switches wallsunsun_threads=6 wallsunsun_blocks=1024 wieferich_threads=3 wieferich_blocks=3072


For Wieferich, try to match the threads to a multiple of the number of MP on your NVidia cards. Blocks seem to work best as a multiple of the VRAM. You should be able to tweak from there.

Also, make sure that you have enough cores free on your CPU to handle the apps as well. My machines range a great deal across in how many they need, but usually it is between 2 and 4 per GPU. Lack of enough free cores will bottleneck the Wieferich application significantly.

I haven't run any ATI cards in a while, so I cannot give a good recommendation of any settings for them.

Also note that you will need to set the device number appropriately in any multiple GPU systems (the GPU affinity setting in the prpclient.ini file does not work in this case).

Hi
Thanks for the info
on one box , 980 / 780gtx the setting doubled the rate to over 1.1m p/sec and halved the time taken.

still can not get the 2rd ATI card to go , suggestions please

your comment about VRAM of the card is interesting as I still can not get any improvement with a Titan Z with 12 gig of VRAM

I have tried up to 12 instances and still no CPU use.

The boxes that are using the CPU are the best. how is that triggered?

any suggestion please.

The challenge stats currently shows two small (17-figures) primes that were found to be near-Wieferichs back in 2012. The right number of near-finds during the event appears to be SIX. /JeppeSN

Which app in prpclient.ini are you using?
My box is running W7 so I am using wwwwcl64.exe, on my GTX970 I get >40mps when using one instance.
All the best, Peter.

Have you altered the number of blocks in wwww.ini? The default values are terrible.

wwwwcl has a "-l" (lower-case 'L') option that will tell you what GPU platforms/devices it sees on any particular box. Linux syntax from the command line would be "./wwwwcl -l" (without quotes). Use that information to set the "platform=" and "device=" values in the wwww.ini file in different prpclient-{N} directories (uncomment them by removing the '//' at the start of the line). Also check what the "wwwwexe=" value is set to in prpclient.ini.

Happy crunching.

Hi
yes
what would you recommend ?
wwwwcl64 will not go on win 8.1 OS has the 0xc000007b bug
wwwwcl64 goes on my win 7 boxes and they do perform better.

will look at it tomorrow 12-47am here

hi
wwwwcl64 except for the win 8.1 boxes
the ati 290x box is running 4 instances in 14 mins @ 2.8m p/sec
the 280x is running 4 in 19 mins @ 2.1m p/sec
none of my boxes are showing much use of the CPU except the 290x @ 0.05

Running 280x / Win7 x64

First instance ~18Mps, wieferich_threads=2, wieferich_blocks=512
Second instance ~30Mps, wieferich_threads=3, wieferich_blocks=512

CPU is i5-3570 at stock speed and is able to do single LLR along with two WWWWCL. Basically, wwwwcl is using most of my CPU cores.
GPU usage is a ~82%.
Or 95-97 if is suspend BOINC LLR and this will squeeze 50+ Mps from R280X.

I don't know what is optimal, I don't really want to play with settings in such a manual manner so I just read a few posts and plucked those ones out to use.
I'm sure someone will look at the above output from the application and will see that I could do better...
Good luck,

As for selecting the optimal settings in wwww.ini. I just found settings that sent my GPU to 95-97% and thought "good enough".

I found that I needed all 6 "real" cores of my i7-3930k to drive my titan 100% with wwwwcl. I assume the program is cpu/gpu hybrid. It seem you need enough cpu resources to drive the gpu to high usage.

Also I ran 2x instances to cater for the drop when the code stops to get more work.

I also found that this setting needs to be set >= number of cores.:

threads=x

The challenge stats currently shows two small (17-figures) primes that were found to be near-Wieferichs back in 2012. The right number of near-finds during the event appears to be SIX. /JeppeSN

There were duplicate entries in my database, where they came from i dont know yet
I eliminate them; I will have a look if they appear again later the day

For the usual naïve conjecture on the distribution of primes with the Wieferich property, the number of such primes in the interval from A to B is (log log B)-(log log A) = log((log B)/(log A)). So in the interval [3.3e17, 4.0e17] there should be 0.00476 new Wieferichs. The number of near-Wieferichs (by our definition) is 2000 times that, so we are going to find 9.52 new near-hits.


The leading edge has passed the goal 4e17. Not all work units have been resolved yet, but it is pretty safe to say that there are 10 near-Wieferichs and 0 Wieferichs in that interval (3 of the near-finds are from before the challenge start).

The first near-find over 4e17 has already been uncovered!

We're almost to the 9.52 near-finds that JeppeSN calculated early in this thread (though how one would find .52 of a prime is beyond me... hahaha). With about a day and a half to go, as I type this, hopefully we'll snag a few more.

The following quote from Wikipedia is a bit discouraging, in terms of the "coincidence":

It can be shown that if there are only finitely many Wieferich primes, then there are only finitely many Wieferich numbers. In particular, if the only Wieferich primes are 1093 and 3511, then there exist exactly 104 Wieferich numbers, which matches the number of Wieferich numbers currently known.

http://en.wikipedia.org/wiki/Wieferich_prime
I know Wikipedia isn't authoritative, but I wonder if we're wasting our time looking for a true (rather than "near") Wieferich prime.

I think you misunderstand a bit. The point is, when we have some Wieferich primes, they can be used, in a specific way, to construct Wieferich numbers (composite), and all Wieferich numbers arise in this way. So from the two known Wieferich primes, we can construct those 104 Wieferich numbers. As soon as we find a new Wieferich prime, we can construct more Wieferich numbers (which will all be greater than the third Wieferich prime).

See Agoh et al.: Fermat Quotients for Composite Moduli (click Download PDF in top). In the very last part, Examples, they show how the 104 Wieferich numbers arise from the two known Wieferich primes (1093 and 3511).

With the usual naïve formula, we can predict the number of genuine Wieferich primes to be found from "here" to different distant search limits.


    In [ 4e17 , 2^63 ] there are 0.0746 Wieferichs
    In [ 4e17 , 2^127 ] there are 0.776 Wieferichs
    In [ 4e17 , 2^255 ] there are 1.47 Wieferichs
    In [ 4e17 , 2^511 ] there are 2.17 Wieferichs
    In [ 4e17 , 2^1023 ] there are 2.86 Wieferichs



There should be 1.0 Wieferich prime for each 2.5695 Mersenne primes, or almost 3.9 Wieferich primes for every 10 Mersenne primes (in the very long run), see my post elsewhere. The region we are currently searching lies between the eighth Mersenne prime and ninth Mersenne prime.

Hi
given up on NV cards and are move one ATI card into most boxes

Have hit the sweet stop with one 290x running @ 4.5m p/sec doing 4 threads in under 10 minutes. that's 24 per hour.
those other ATI cards generally are running over 2.1m to 3.1m p/sec and are doing 8 threads per 20 mins same 24 per hour.

NV cards may work hard but none of them can get within that sort of output
24 per hr.

Have 2 win 8.1 boxes doing CPU tasks as the 0xc000007b bug stops them running wwwwcl64. have HT ed one 5930 and its running very happy on 12 tasks.

the challenge will end soon
best of luck

I don't want to get into an ATI v NV war here...

With my NV-Titan, I can get 1 per 35secs, which equates to about 100/hr.

Unfortunately my cpu died. So the titan is off wwwwcl as I can't drive it to 100% with the cpu I currently have.

That seems about right to me. I am getting a max of about 72 secs per unit on my GTX 660Ti, which has about one-half the shaders of a Titan (Wieferich does not benefit from DP). With this work, it is all about having the 1)optimized thread and block setting, 2) enough cores free, and 3) memory size and speed (Wieferich uses cache and if needed regular RAM...CPUs with better cache and higher speed and more channels will do much better with feeding the GPUs faster).

Have hit the sweet stop with one 290x running @ 4.5m p/sec doing 4 threads in under 10 minutes. that's 24 per hour.
those other ATI cards generally are running over 2.1m to 3.1m p/sec and are doing 8 threads per 20 mins same 24 per hour.

NV cards may work hard but none of them can get within that sort of output
24 per hr.



Edit: oops, I see others raised the flag while I was off writing. But I'll put in that my 7950 is currently running about 44M p/s and 56 seconds/task. My .ini settings for your consideration are blocks=3000 and threads=7 (same as #CUs since there's a prime number of them)

I have 7970 and I am doing one Wieferich every 53 seconds.
I am using 5 threads and 1024 blocks on a 6 core machine, X6 1100 CPU. I suggest commenting out the platform and device lines as your device could be 0 and not 1. Is running 100 percent on your CPU by the look of it.

Did you copy the wwww.ini file into each instances' directory?

Why does this not happen automatically when the install bat file is run?

Further to:
Titan z does 74m p/sec 1 task taking 33 secs, 2 tasks take 54secs running at 46m p/sec
currently with all boxes now converted, "yeah" doing 500 tasks per hour.

I had a hard look at all the info provided for this mini challenge, but nowhere does it say to copy the wwww.ini to the "instance".
It appears that some people did know. Thanks to GDB for the info.
Perhaps the team at PrimeGrid could change that and have another challenge with everyone able to crunch properly.
Cheers
and happy crunching

85m p/sec 1 task 29secs.
that is slightly better than the ATI 290x, and the Titan Z same settings
Found that one of my 290xs had my ID as PG_Rosss*, 1740 tasks now fixed.

Ooooo, look at all the pretty colours.

Using Linux Mint, GTX 760 with 2 GB, nvidia driver 319.72, and 4 instances of wwwwcl, which had been running for hours.

Opened a console window (pressing control-alt-F1, or one of the other tty consoles). Watched as wwwwcl puts artful dot and dash patterns of mixed colours all over the console screen, even chewing up the login prompt. Expecting invalid results to be sent back to the server while typing and scrolling in the GPU application's memory.

Reactivated desktop GUI with control-alt-F8. Cinnamon desktop claims it crashed. Restarted it with the appropriate mouse click. Also stopped and restarted prpclients, which got stuck at 100%. Aborted work units and started over. Looked for console entertainment again. Nothing happened (after only a short time).

Looks like a one-off glitch or a problem potentially related to a memory leak.

Congratulation to zzcmeyer, Aggie_The_Pew and all the people who got a "near find"!

First positions are as follows:

top users 1) zzcmeyer 131,795 2) zunewantan 119,326 3) 288larsson 57,648 4) Scott_Brown 36,161 5) Honza 25,923 top teams 1) Aggie_The_Pew 199,248 2) Sicituradastra. 77,267 3) SETI.Germany 41,656 4) Duke_University 36,160 5) BOINC.SK 25,923

We've pushed the leading edge to 4.142e017.
Remember 9.2e18 is the upper-bound the current software can search to.
Special congrats to zunewantan with his 5 near-finds.
With 11 near-finds total we had a 11/1999 = 0.55% chance of finding a true Wieferich prime.

Make a suggestion for the name of the next PRPNet challenge:
http://www.primegrid.com/forum_thread.php?id=5941&nowrap=true#80452

See you at the next challenge!

Bingooo!

I enjoyed that.

Found 1 of the clients had crashed about 13 hours ago, but still safely in 14th overall. I was in danger of being Roger-d so I even swapped my 4yo router out during to maintain net uptime.

Back to PSP clean-up help + trying to finish that WR. Then I'll carry on with more WFS, but with BOINC going as well is there a GPU PSA project that doesn't require a free CPU?

The Wall-Sun-Sun application is less CPU intensive than is Wieferich. However, note that screen lag is typically more common with WSS than WFS.

I had a hard look at all the info provided for this mini challenge, but nowhere does it say to copy the wwww.ini to the "instance".
It appears that some people did know. Thanks to GDB for the info.
Perhaps the team at PrimeGrid could change that and have another challenge with everyone able to crunch properly.
Cheers
and happy crunching

As I joked somewhere before, the challenge was getting it running well in the first place. I flicked through the links and old threads, but it took a while to find the right software (MS something download) to allow it to run at all. Then once running, I wondered, is it running as expected? I expected the GPU to be used but you can use something like gpu-z to monitor how much of it is really used. In this case, almost nothing. More reading suggested I needed to edit the ini file, which is unreadable in windows notepad as it was in either unix or mac format. Download notepad++ and I was cooking... except the performance still wasn't changing. I noticed it wasn't copied into the running instance so did it manually, and away we go.

It would have saved a lot of time if there was a single post describing these needed steps.

I'm away from home so mine will be running for another day or so before I switch back to boinc.

Hmm yes if it was more widely known we would have stopped at 16:30 too...

In fact I think the end should be backdated to 09:37. & I'm not saying that because I lost a place.

Hi
This is a team effort for PG.[/quote]. I would agree, and if everyone had known about that little paste in to the wwww.ini instance file so much more would of been done.
I went from 100 per hr[2400 per day to 600 per hr or 14000 per day
happy crunching

Congratulation to zzcmeyer, Aggie_The_Pew and all the people who got a "near find"!

First positions are as follows:
top users 1) zzcmeyer 131,795 2) zunewantan 119,326 3) 288larsson 57,648 4) Scott_Brown 36,161 5) Honza 25,923 top teams 1) Aggie_The_Pew 199,248 2) Sicituradastra. 77,267 3) SETI.Germany 41,656 4) Duke_University 36,160 5) BOINC.SK 25,923

We've pushed the leading edge to 4.142e017.
Remember 9.2e18 is the upper-bound the current software can search to.
Special congrats to zunewantan with his 5 near-finds.
With 11 near-finds total we had a 11/1999 = 0.55% chance of finding a true Wieferich prime.

Make a suggestion for the name of the next PRPNet challenge:

See you at the next challenge!

Hey, I thought I passed Honza ;)

One way is to edit all of your relevant prpclient.ini files to use "startoption=2". Then, restart prpclient in each directory. It will return completed work, abandon (cancel) the rest, then shut down.
