Team drive #13: k=400-600 n=1M-2M
 
This is team drive #13 for No Prime Left Behind. We will be searching all k=400-600 for n=1M-2M.

Karsten (kar_bon) has created a web page that shows details for the drive [URL="http://www.rieselprime.de/NPLB/Drives/NPLB_Drive13.htm"]here[/URL]. He maintains a site that lists almost all known Riesel primes. There is a page for the entire range of 300<k<2000 [URL="http://www.rieselprime.de/Data/00300.htm"]here[/URL]. The ranges searched and primes found from this project will be shown there.

A PRPnet server will be processing a large part of the range. See [URL="http://uwin.mine.nu/prpnet"]Lennart's PRPnet clients[/URL] to get the latest PRPnet client, and [URL="http://www.mersenneforum.org/showthread.php?t=12224"]this thread[/URL] for information on our currently operating PRPnet servers. The info specific to this server that needs to be entered into your prpclient.ini file is:

server=G9000:100:1:noprimeleftbehind.net:9000

[B]For manual reservations, please request a file from the admins and we will send it to you. It is requested that manual reservations take no longer than ~3 weeks and that they be [/B][B]in multiples of no less than n=100.[/B]

Please report all primes found in [URL="http://www.mersenneforum.org/showthread.php?t=9891"]Report all k<=1001 primes here[/URL] thread. For manual ranges, please report all reservations/statuses/completions for this drive in this thread, and post all results files in this thread or send them to Gary at: gbarnes017 at gmail dot com.

Please report all top-5000 primes with a project ID of 'NPLB'.

435*2^1853363-1
[/code]All of the primes found in this range will be over 300,000 digits, and will grow steadily in size as the drive progresses. As of this writing, primes of this size come in within the top 1000 largest known primes! This drive, with its potential to produce quite a number of megabit primes, should prove most interesting. :popcorn:

1000K-1100K has been completed by LLRnet port 3000 and PRPnet port 9000; processed results have been emailed to Gary.

The port 9000 status pages should load a lot faster now--the server's database has been significantly lightened with the removal of this range and, particularly, a huge chunk of the 7th Drive that had been sitting in there for over a year. I'll be similarly processing and cleaning out port 2000 next, and then will upgrade both servers to the latest prpserver version 5.0.8.

I just optimized the database tables for that port now the range is removed.
should be a touch quicker.

Excellent, thanks! (Wow, it loads fast--I just pulled up [url]http://noprimeleftbehind.net:9000/all.html[/url] in half a second flat! :w00t:)

BTW, how does one go about optimizing the tables (what commands, etc.)? You've probably told me before but I can't recall it for the life of me... :rolleyes:

[QUOTE=AMDave;310068]email sent[/QUOTE]
I am afraid max isn't the only one interested. Am I right in thinking that optimising the tables after adding a rediculous amount of candidates is just as helpful as doing it after deleting them? I created a server recently with too many candidates and it took ages to respond to the client.

CGKIII 2012-09-03 05:50

Similar request for info. I started my personal server with ~1000 k's at n = 2500, originally loaded with a bit over a million candidate tests. I've gotten it down to 500,000 due to a lot of messy SQL (and completing tests / finding primes), but it would be awesome to get some better code. Of course, next time I'll narrow things down a bit more first.

It turns out it's pretty simple: just run "optimize table [I]table[/I];" for each table in the database. (I'm assuming you already know the basics of getting in and navigating through an SQL database, since you were able to clean out old tests from your server.)

Is there any particular reason why drive 13 is so far behind drive 14 even though it is easier and has lower ks?

kar_bon 2012-09-18 11:13

[QUOTE=henryzz;312069]Is there any particular reason why drive 13 is so far behind drive 14 even though it is easier and has lower ks?[/QUOTE]

Because there's more activity on Drive 14 (Port 2000) than on Drive 13 (Port 9000):

the last days there were ~300 paris done on Port 2000 but only ~30 on Port 9000.
End of August the difference in pairs was much higher.

[QUOTE=henryzz;312069]Is there any particular reason why drive 13 is so far behind drive 14 even though it is easier and has lower ks?[/QUOTE]

We had two rallies on drive 14 when it was behind drive 13. Then a big cruncher stayed on drive 14 for a long time afterwords. Our next rally will be on drive 13.

I seem to be searching all the primeless ranges on this drive so that everyone else can find the primes. :no: There's been one prime in the last n=23K range; by far the worst range since the drive started. I wonder if all of my machines have gone bad at once.

Must be because I started crunching there on 2 cores...my luck's been pretty poor on this server, with 15704 tests (approx 1.5-2 primes expected; most of those tests were long ago when the numbers were smaller) and 0 primes.
[QUOTE=MyDogBuster;335565]Probably setting up for a nice run shortly.[/QUOTE]
I'd like to think so, but that's a good example of gambler's fallacy. Crunching primes in NPLB, CRUS, etc. has taught me a great deal about probability and randomness: expect the unexpected. But don't be surprised when it plays out as the most likely scenario, either. And if you ever think you know what's going to happen based on past random events, you're (probably) wrong.

Mini-Geek 2017-08-28 01:04

I have confirmed that 405*2^1508592-1 is prime. I tried to submit it to the Top 5k before I realized it was already known. :blush:
