121 - ESCO 2016 - European Seminar on Computing Challenge - 05-12 June

Announced is a challenge at the 121 prime search project from the 5th till 12th of June. I suggest we start at 12:00 UTC and end at 12:00 UTC.

ESCO 2016 is the 5th event in a successful series of interdisciplineary international conferences. It promotes modern technologies and practices in scientific computing and visualization, and strengthens the interaction between researchers and practitioners in various areas of computational engineering and sciences.

2016 Main Themes:
•Computational electromagnetics and coupled problems,
•Fluid-structure interaction and multi-phase flows,
•Computational chemistry and quantum physics,
•Computational civil and structural engineering,
•Computational biology and bioinformatics,
•Computational geometry and topology,
•Mathematics Education and Outreach,
•Petascale and exascale computing,
•Hydrology and porous media flows,
•Wave propagation and acoustics,
•Climate and weather modelling,
•GPU and cloud computing,
•Uncertainty quantification,
•Open source software.

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!

And PRPNet port 12001 is here.

Clearly 121 is a square (in fact 11^2, a wonderful Demlo number).

The plus form:

Primes 121*2^n+1 must necessarily have n even. For if n were odd, taken modulo 3, our 121*2^n+1 would be 1*(-1)^n+1=1*(-1)+1=0 (meaning 3 divides our candidate).

Then, with n even, this is actually a generalized Fermat prime B^2+1 with B=11*2^{n/2}.

The first exponents are 8, 12, 44, 84, 96, 228, 264, 320, 732, 788, ....

The minus form:

On the other hand, for 121*2^n-1 to be prime, n must be odd. This can be seen as before, by checking modulo 3. When n is even, beside the factor 3 found in this way, we can also find two huge factors, because B^2-1 = (B-1)*(B+1).

The first exponents are 1, 3, 21, 27, 37, 43, 91, 117, 141, 163, 373, 421, ....

I've started pre-load.
Last 121 challenge I was dong 17 hours per WU. So starting this far out on the pre-load have 2 WU per core.
No GPU at the ATM so load profile relatively flat. Allows me to run 6 cores rather than the usual 5 on my AMD 1100T X6 CPU.
1 core 5.97ms per iteration => 0.167 work
2 core 6.60ms per iteration => 0.303 work
3 core 7.20ms per iteration => 0.416 work
4 core 8.10ms per iteration => 0.493 work
5 core 9.80ms per iteration => 0.510 work
6 core 11.2ms per iteration => 0.535 work

Obviously flattens out as you add more cores due to memory saturation. 6th core still worth it without the GPU.
Will head back to 1 WU per instance once the challenge starts.
6 day expiry on these WU's so could have had a bigger run up, but life is busy.
I think we're well due for a prime on this port.
Load up and enjoy the challenge.
Cheers, Roger

Thanks oozo, the PRPNet download has moved. Can now be found at:
http://prpnet.primegrid.com/
Is also at "PRPNet server" on the Primegrid menu on the left.
Time to update some of the web pages.

If I have an 8 core cpu, how can I get all 8 cores to do work units? Have tried different things and will not work.

Also, have two amd r9 380x, how do I have them do work?

One more thing. My i7-4790k is doing work faster than a e5-2623 v3 cpu, by FAR!! Is that okay? Seems something is wrong here.

this is the master file for the i7-4790k:

// email= is a REQUIRED field. The server will be use this address
// to send you an e-mail when your client discovers a prime.
email=wdethoma@hotmail.com

// userid= is a REQUIRED field that will be used by the server
// to report on stats, etc. without having to reveal the user's
// e-mail address. DO NOT USE spaces. Instead use underscore _.
userid=wdethomas

// This value differentiates clients using the same e-mail ID
// DO NOT USE spaces. Instead use underscore _.
machineid=msi

// This value differentiates instances on a machine
// This will be set automatically by the *-update-prpclient-ini script
// If you prefer to setup up prpclient directories manually, please
// set this to a unique identifier (e.g. 1,2,3,4...)
instanceid=INSTANCE_ID

// Tests completed by this "team" will be rolled-up as part of team stats. This
// will be recorded on tests that are pending and then updated when tests are
// completed. Since it is stored on the server per test, it is possible for a
// single user to be a member of multiple teams. If no value is specified for
// this field, then completed tests and primes will not be awarded to any teams.
// DO NOT USE spaces. Instead use underscore _.
teamid=

// server= configures the mix of work to perform across one or more
// servers. It is parsed as follows:
// <suffix>:<pct>:<workunits>:<server IP>:<port>
//
// <suffix> - a unique suffix for the server. This is used to distinguish
// file names that are created for each configured server.
// <pct> - the percentage of PRP tests to do from the server.
// <workunits> - the number of PRP tests to get from the server. The
// server also has a limit, so the server will never return
// more than its limit.
// <server IP> - the IP address or name for the server
// <port> - the port of the PRPNet server
//
// Setting pct to 0 means that the client will only get work from the
// server if it cannot connect to one of the other configured servers.
// Please read the prpnet_servers.txt in this directory for information
// on the latest PRPNet servers.

// The following servers are from PrimeGrid. To make a server active,
// you must remove the "//". For more information about proper settings
// please see the readme_primegrid.txt in this directory.

If you have 8 core cpu you should click first on the 8-oct-install-prpclient.bat file. This will make 8 folders (1 for each core)

Then you change the master_prpcclient.ini file and include all the information like email and stuff and in the line where [// server= configures the mix of work to perform across one or more] is you should replace that with the exact line
server=121:100:1:prpnet.primegrid.com:12001

when you have saved the master_prpclient.ini file you click on the 8-oct-update-prpclient-ini.bat and that will copy your master ini file to all the folders you made earlier.

When you want to start the prpclient you then click on the 8-oct-start-prpclient.bat and that will start 8 cmd prompts. You can shut down 1 or more if you want to for example just run 7 if you need 1 core to feed your gpu for other program.

Lastly this particular program (the 121 prime search) doesn't have a gpu program so it is cpu only.

Did it now. Thanks

I assume that I need to specify also the 64 bit wu too, correct?

Looks like Williamd007 might have found a Prime! Well done.
Still needs to be verified, but looks very promising.
Looks to be of the minus form, 121*2^n-1.
Last prime on this port was found by Pooh_Bear_27 1562 days ago.

I'm testing that candidate, but you should know that we get a huge number of fake primes where c = -1. There are currently sixteen of them on PrimeGrid. While most are Woodall, there are two SGS in there at the moment. We'll know in a little over four hours.

The test that LLR uses when b=2 and c=-1 is prime when the result at the end of the calculation is zero. Calculation errors often produce a result of zero. So we get LOTS of false primes on candidates of that form, especially large numbers.

We typically don't get excited when such a candidate is initially reported as prime. 99 times out of 100, it's an error. But there's always that 100th time...

We'll know soon enough.

I'm hoping that by pointing out how bad the odds are I will influence the outcome and make it actually be prime! :)

It's not prime. I've inserted the residue I got and sanitized the PRPNet database.

EDIT: There's now a 2nd prime showing up for that same user, same host. It has a 99.99% chance of being false. We know from experience that malfunctioning hosts generate a lot of them.

Bummer, rebooted and removed minor over clock.


I recommend running only BOINC tasks (except SGS-LLR, PPS-LLS, and PPSE-LLR) for now to establish that it's working reliably. Since PRPNet tasks aren't double checked, you have no way of knowing whether it's working correctly or not.

Sorry, I hope this is not a redundant newbie question. I've been participating in PrimeGrid since April, and figured it's time now to turn it up a notch and also install the PRPnet client. What better time to do that, than when the challenge started, right?
But I'm not sure if I have fed PRPNet with the correct information to link to my PrimeGrid account. I followed the instructions, put an underscore instead of space in my username, etc.
The reason why I'm not sure if it works is that I thought the idea was that PRPnet work units would generate credit under the PSA badge. But that doesn't appear to be happening. I can see my username here: http://u-g-f.de/PRPNet/challenge_stats.php as 9th on the list, so I guess my machine is contributing work units properly, but on the list of badges no PSA badge counter has appeared yet (and I didn't have a PSA badge from prior tasks, since I'm only a fairly new member).
Any way to check if the connection between the systems is working as intended?

No need to worry at the moment. PSA to Primegrid credit is done on a weekly basis pretty much. As this is a manual system, one of the admins (Jim or Mike I believe) in their infinite amount of free time total the credits earned and then transfer to PG.

Please note it is not a 1 to 1 credit transfer. Some of the projects get 20 to 1 and some get 10 to 1 in terms of ratio (I think as it's been quite some time since I've done any). However I am sure someone will correct me and give you the right numbers.

Cheers Rick

Yet another "prime", same user and same host. I'll start testing it in ten minutes but that's just a formality - it will be composite.

And yes, Mike transfers credit into PrimeGrid from PRPNet at no less than weekly intervals. The two systems are not connected.

EDIT: 121*2^6820117-1 is not prime. LLR Res64: 68FAC89AD713B78D Time : 42471.975 sec.

After 2 full days of the Challenge we've done 1295 WU's.
5th June 256 WU's (half day)
6th June 670 WU's
7th June 369 WU's (half day so far)

zunewantan and Aggie_The_Pew firmly in the lead.
Up to n=6,836,323 on the minus and 6,836,480 on the plus side.
At this rate we'll soon hit the goal of 6.85M.

Homework question (no Admins allowed):
If Prime is found at leading edge given above, what would be its current Prime rank?

Sounds right because #31 is also about 2^(6.8 million). /JeppeSN

And if from the plus family, it would come in 5th on the GFN list, dwarfed only by the four GFN19 primes (it would be a GFN1 prime as I explained in my June 3 post above). /JeppeSN

We have implemented a new policy regarding computers returning bad results on PRPNet. Effective immediately, we reserve the right to stop granting BOINC credit for PRPNet work done by participants whose computer(s) return an excessive number of bad results.

This is being done for two reasons. The first is that it's simply not fair to everyone else. The second reason is that it creates a lot of work for the admins, and we'd strongly prefer that people run their less-than-totally-stable computers on BOINC, which handles them automatically.

Please see http://www.primegrid.com/forum_thread.php?id=6856.

A fourth false prime has now been retested and removed. And this morning there are two more. For every one of these I have to manually modify 7 different database tables where a typo can screw up the entire 121 port. And fake primes are just the visible manifestation of problems with this computer. I can look at any computer that's returned a false prime on BOINC and see that there are many more invalid results. We can't trust any result from that computer as PRPNet work is not doublechecked unless a result shows as prime.

None of this user's work during this challenge should count for anything. It cannot be trusted.

Edit: Correcting what I said above: None of that hosts's work done during the challenge should count. And possibly no work that host ever did. And those candidates should be requeued for testing by a different host.

Ok so upon discovering the evga memory chips in this computer are not on the "Approved" list, nor the configuration of them I was using. I took the 6700k offline and printed out the approved list. I just came back from microcenter, 258.00 poorer, with "Approved" 4x4 gig sticks of Corsair platinum cmd16gx4m4b3600c18 memory, that have their own fan cooling system with led lighting. 1 for each chip. I jokingly asked about liquid cooling memory, but apparently that's not yet available.
This was the only ones they had in stock on the "Approved" list. I am about to shutdown now and change the memory. The only way I can check after is to run prpnet 12001. I f you want me to wait till after the challenge that's fine with me. But I have no other way to be sure at that point. Kudos to the person who tipped me on "It's usually a memory problem", as this seems to have been the case.
