Team drive #4, 15 k's < 300 for n=600K-1M
 
[COLOR=black][FONT=Verdana]ANNOUNCING...drum roll...[/FONT][/COLOR]

[COLOR=black][FONT=Verdana]Team drive #4 for NPLB! This will be a very exciting drive where we will be searching k=115, 149, 175, 179, 185, 199, 215, 227, 229, 239, 241, 265, 271, 289, and 293 from n=600K-1M! Sieve depth is P=26T.[/FONT][/COLOR]

NOTE: Brucifer did all of the sieving for this effort himself. Personally I am going to share the 1st prime with him that I find on it. I might suggest that some others do this also. Sieving doesn't get the recognition that it deserves so perhaps this will help some. Thanks Bruce!

Karsten (kar_bon) maintains a site that has almost all known Riesel primes. There is a page for k<300 [URL="http://www.rieselprime.org/Data/00001.htm"]here[/URL]. The ranges searched and primes found from this project will be shown there.

3 excellent LLRnet servers will be processing a large part of the range. For general info. on setting up and running the servers see [URL="http://www.mersenneforum.org/showthread.php?t=9959"][COLOR=#22229c]this thread[/COLOR][/URL]. The info. specific to the servers that needs to be entered into your llr-clientconfig.txt file is:

#1:
server = "nplb.ironbits.net"
port = 7000

#2:
server = "nplb.ironbits.net"
port = 7500

#3:
server = "nplb.dynip.telepac.pt"
port = 443

Please report all reservations/statuses/completions for this drive in this thread. Please report all primes found in the 'Report primes here' thread. Please post all results files in this thread or send them to me at: gbarnes017 at gmail dot com.

Please report all top-5000 primes with a project ID of 'PrimeSearch' and credit LLR and srsieve software.

Just to let all know that server C443 is already sending to the clients candidates from Drive 4. You Guys can point the cores to C443...lol. The rest of the candidates from Drive 1 will be completed by me (ETA ~30 hours).
PrimeSearch will definitely raise a few spots in the score rankings with this drive...let's see.

Manual files have now been posted. Port 7000 should be loaded up later today.

em99010pepe 2008-09-09 20:06

Gary just took and run one candidate to see if the server was running...lol
I think it's better to reserve more work for this server.

Just got home and loaded up 7000.
Let me know if you run into any problems.

ROCK ON!!

David, I'm putting 2 quads on port 443 shortly until it cleans its current range, which should be within 1-2 days. I'll then move them over to port 7000. Don't worry if you get only a small amount of activity at first.

Thanks for taking care of it.

Let's roll! :smile:

Just to set everyone's expectations right here: At this level of n-range and the # of candidates in the file, I would expect an average of one prime approximately every n=10K-12K.

gd_barnes 2008-09-10 06:55

I moved all of the posts related to the C443 server issues to a new thread by that name.

em99010pepe 2008-09-10 08:41

Taking 610-614.

em99010pepe 2008-09-10 20:17

Taking 614-618.

em99010pepe 2008-09-10 20:22

I urgently need more work for server C443, less than 850 candidates to test. I need a 10k or 15k file.
