Public PRPNet Servers
I am creating this thread to list the known public PRPNet servers hosted by various projects. These are the current servers that I am aware of. If you know of any corrections or additions for this list, please follow up in this thread. Eventually an admin will keep this post up to date.
The latest version of PRPNet is available from here. Server: prpnet.primegrid.com port: 12000  Sophie Germain Prime Search: k*2^6666661 port: 12001  121 Prime Search: 121*2^n+1, 121*2^n1 port: 12002  Factorial Prime Search: n!+1, n!1 port: 12003  Generalized Fermat Prime Search: b^65536+1 port: 12004  Generalized Cullen/Woodall Prime Search: n*b^n+1, n*b^n1 port: 12005  Generalized Fermat Prime Search: b^32768+1 port: 12006  27121 Prime Search: 27*2^n+1, 27*2^n1, 121*2^n+1 port: 12007  Proth Prime Search Extended: k*b^n+1, 1200<k<10000, n>500000 port: 12008  Primorial Prime Search: p#+1, p#1 Server: pgllr.mine.nu port: 9000  Prime Sierpinski Prime Search port: 10000  Proth Prime Search Extended: k*b^n+1, 1200<k<10000, 130000<n<140000 Server: prime2u.com port: 11000  Proth Prime Search Extended: k*b^n+1, 1200<k<10000, 140000<n<150000

Here are two more public PRPnet servers, for NPLB and CRUS respectively:

Server: www.noprimeleftbehind.net port: 1300  Sierpinski Base 22 Conjecture (CRUS): k*22^n+1 port: 9000  Riesel Prime Search (NPLB): 400<k<600, 600000<n<1000000 I noticed that port 1300 is an older release of PRPNet. Since port 9000 is at 3.2.5, is there a plan to get port 1300 up to that release as well? It also seems that the user stats are messed up. I would recommend clearing those stats or rebuilding user stats from completed tests. Last fiddled with by rogue on 20100530 at 21:07

Regarding the stats, in what way are they messed up? They look fine to me.

Note that the server didn't always have large base 22 tests in it; initially, we ran comparatively smaller Sierpinski base 6 work on that port. Perhaps that caused an apparent disparity in the number of tests vs. points? (AFAIK, most of Lennart's points were from S6 work, and most of Gary's from S22, if that helps.) Or is there something else entirely that I'm not seeing here?

Code:
insert into userstats (userid, testsperformed, prpsfound, primesfound, gfndivisorsfound, totalscore) (select distinct userid, count(*), 0, 0, 0, sum(decimallength * decimallength / 100000000) from candidate,candidatetest where candidate.candidatename = candidatetest.candidatename group by userid); 1) Users won't get credit for tests that are no longer on the server. If you have archived the tests for base 22 (and only base 22), then you should be able to figure out the user stats from that data. I will help you if you need it. 2) It loses primes/prps found, but you can either update this statement manually to compute those values or you can update the table with additional SQL statements after running this one. 3) It does not exclude tests that have not been returned. You just need to exclude records from CandidateTest where the Residue is null.

Hmm...I just thought of something. Was I by chance supposed to leave onlytest.removed in the server directory when I ran ./prpserver u to have all those completed tests imported into CandidateTest? I moved that file out of the directory and into a subdirectory where I was putting the old 2.4.6 files for safekeeping prior to the upgrade. Oh well. Even if I did keep onlytest.removed in there to be imported into the DB, that still wouldn't cover a lot of the testsmany of the old base 6 tests were done four or five times over when we were debugging the blankresidue problem way back when, and once that was all over the mess was just too much to sort through so I picked up all the server files, dumped them into a subdirectory, and started clean for base 22. So while the stats still count the base 6 tests, only the base 22 tests would have been on record in onlytest.removed. I'm a little reluctant to blank out the user stats entirely considering that, since CRUS does not have a stats database a la NPLB, this is our only source of stats for this port. I don't suppose there's a way to figure out a ballpark figure of where Gary and Lennart's stats "should" be, so I could just fix them manually? (Or I suppose I could just delete Gary and Lennart's stats entirely and leave everyone else's apparentlyOK figures be... )

Since it is a "base 22" server and since the base 6 stats were amuck, it should be fine to only include base 22 in the stats. You should ask Gary and Lennart if they care about their stats on that particular server. Computing an estimate for them might not be too difficult since you know how many tests they completed and probably have an average decimal length for those tests.
