NPLB (No Primes Left Behind)


How do we get the project NPLB added to the DC Vault?
Mathematics Category I would assume.

TIA

I second IronBits proposal to add NPLB in the DC-Vault.

I think adding another Prime Search Project in the Math section is starting to over wait the vault toward this one type of project.

I see there are only 5 teams actively crunching this project. http://stats.free-dc.org/stats.php?p...plb&sort=today
and only 10 teams ever to crunch for this project. http://stats.free-dc.org/stats.php?page=teams&proj=nplb

Are the stats still done manually by hand with no automated script?
I can't even find where to find what is needed to run the project.
What OS platforms does it support?
Is this the extent of there website? http://nplb.ironbits.net/


Edit: After looking further into this project and setting it up and running it, I find this prime project to actually be a bit refreshing.
- So I would like to retract my comments here and recommend NPLB to the DC-Vault for consideration.

Forgive my ignorance...but I never really understood the importance of finding primes; that said , I've looked at the project [NPLB] and as an upstart may deserve consideration....later

NPLB more project info.

Hello,

I am Gary Barnes, project admin for "No Prime Left Behind" (NPLB).

David (IronBits) has posted a lot of useful info. and links about the project but I thought I would mention some more things.

Our purpose: We are a prime search project that finds both small and large primes numbers of the form k*2^n-1, commonly referred to as "Riesel Primes". We attempt to "fill in" where other projects have left "holes" in the Riesel Primes "universe", hence our project name.

Our accomplishment: In 16 months time, we have now become the #2 prime search project on the web as for the number of primes that are in the top-5000 largest of all time. We are also #7 as for primes "score" and are rapidly gaining on the 2 projects ahead of us.

Some additional links:
Our home forum page: http://www.mersenneforum.org/showthread.php?t=9887
Our top-5000 primes project ID: http://primes.utm.edu/bios/page.php?id=518 (please see the description in the middle of the page)
Our main stats web page: http://stats.ironbits.net/statsnew/nplbstats.php


Other threads also give directions on the software that is used. Our "come join us" thread gives specific goals of the project.

Automated testing is available on several of David's very robust servers. We have run rallies on the servers with 500 or more cores with no problems. For those who prefer to go their "own way" in searching for Riesel primes, we have ways of helping you accomplish that. We currently have 3-4 people searching for us who have gone that route.

Files are readily available for testing right now. Testing at our current ranges takes approximately 5-10 mins. per test. The chance of a test being prime at our current testing levels range from 1 in 6000 to 8000. Most primes found will be in the top 5000 of all time and will be recognized on the above top-5000 site as in the top-5000 of all time, with the discover's name saved for mathematical historical reference. If preferred, discover's can remain anonymous.

Many may ask: Why do we search for large prime numbers? Several reasons:
1. Most importantly: They are used for many encryption methods to keep transactions safe, especially on the internet.
2. NASA scientists have decided that primes are a good sign of intelligence and have included a short list of them on plaques sent out with the voyager spacecraft.
3. Someday it is hoped that the "code" of prime numbers will finally be broken. With all of today's technology, we can no more say where the next prime number will be then could people 100's of years ago.

While our teams may appear small in number, we are dedicated and committed to what we are doing. At all times, we have 200-250 cores running for the project now. During rallies, that will top 500.

We have come a long way in a short time but would now like to reach for new heights.


Thank you,
Gary Barnes

In other words, yet another prime project. Although I personally like these projects, we should be careful that we do not change the Vault into a competition of finding primes. We already have 7 "projects" searching for primes. These projects are trying to:

SoB (+sieve): Solve the Sierpinski problem
PSP (+sieve): Solve the prime Sierpinski problem
GIMPS: Find record primes
Wieferich: Find new Wieferich primes (there are only two known so far)
PrimeGrid: Runs a lot of prime projects through BOINC.

And then we have:

NPLB: Find Riesel primes (preferrably top 5000 primes).

Also, I'm not too happy with adding another project that is using llrnet.
* Llrnet does not support windows 2003.
* It is not using the newest version of llr, so there is a loss of speed.
* I've emailed with the developer, and he does not have the time to maintain the software.

The best for DC-Vault would probably be that NPLB joins PrimeGrid before it's added to the Vault...

Yes, another prime search project but of a different kind than all but one that you mentioned; PrimeGrid: There is a reasonable chance to find a prime. That is, the tests are far smaller but still large enough to be interesting.

LLRnet is not used exclusively. We have several people who do their own searching manually and a couple who actually prefer it. IMHO, the speed disadvantage of LLRnet is only a small annoyance compared to the convientence factor.

The idea of being listed here was proposed to me by several team members and they made it sound like people here would be receptive but that has certainly not been the case in this thread so far. We are not begging for publicity because we have had plenty of success by only word of mouth. We only felt that it would be a way to spread the word about it.

There is a person from here named Russkris who is talking with us in our forum threads who seems quite excited about the enthusiasm that our project members show. Therefore, I think that checking out Russkris's comments in one of our threads at http://www.mersenneforum.org/showthread.php?t=11754 would be better than anything I could say here.

Edit: As excellent of an effort that PrimeGrid is, NPLB feels we have no need to go that route. Further: We do not desire a BOINC-related setup in any fashion.


Gary

I can confirm that NPLB does support Linux, FreeBSD and also Windows XP Home and Pro, Windows 7 Ultimate and Windows Server 2008.

NPLB can be run in the background when BOINC is running and have a limited affect on both programs.

That would be me... LOL...

Now you have told everyone about the thread, I wonder if I have said anything stupid.
This is the first time EVER, the project admin have worked so to please what I have asked, and have been active in coming here to post.. So Thank you

Don't forget Vista 32bit and Vista 64bit (all versions of both), with scripts written to handle multi-cores and affinity.
