LLRnet rally Apr. 30th to May 2nd

Hi everyone,

I'd like to announce NPLB first LLRnet rally in over a year! The rally will begin on Friday, April 30th at 7:00 PM GMT and run for 48 hours until Sunday, May 2nd at 7:00 PM GMT. It will be run on our port 3000 for k=400-600. Tests will likely be in the n=765K to 775K range during the rally.

Keep in mind that these small k's will test faster than all k>600 at many search limits. All k<400 is already at n=1M and we are hoping to push this range towards that limit by year end.

LLRnet config info.:
server = "www.noprimeleftbehind.net"
port = 3000

Be sure and change your userID to whatever ID you generally use. It is also best to set the cache at from around 2 to 10 pairs.

This will be the first rally ever run with a full speed LLRnet client running speedy LLR 3.8. Please see information for downloading the new LLRnet client at http://www.mersenneforum.org/showthread.php?t=13165. If anyone prefers, he can still run the old client but it will be slower.

For those of you who would prefer to run PRPnet instead, Max (mdettweiler) has graciously agreed to set up a private PRPnet server for you on my server machine with pairs near the same n-range as will be run for the rally. Just let us know at least 2-3 days ahead of time.

As a point of interest for those who might be new to NPLB and for others who haven't done any testing with us for a while, we have some milestones that we would like to shoot for in the near future. Please refer to our primes graph and drive progress at http://www.noprimeleftbehind.net/sta...drive_progress as well as to our "countdown meter" at http://www.mersenneforum.org/showthread.php?t=13333. NPLB's goal all along has been to fill in holes in the prime search ranges for Riesel base 2. We'd like to get the dots in that k=300-1001 range fully extended to n=1M by year end 2011 so that they are closer to where k<300 (worked by RPS) is at. In targeting k=400-600 for this rally, we have set a relatively aggressive goal to have it tested completely to n=1M by year end 2010.

Personally I think ROLP will kick Free DCs butt this time around. After they had us for a BBQ the last couple of times, we're ready with a surprise or two this time. Regardless of the friendly competition, we'd like to make a dent in the range to give us a good chance at our goal by year end. Thank you for any consideration that you can give.
