This is a thread for general news for No Prime Left Behind (NPLB)

A few topics of interest to get us started:

1. Please post all results files in the status thread upon completion of your ranges or alternatively you can Email them to me at:
gbarnes017 at gmail.com. Also, if you can please post or mail past results to me that you still have available, that would be helpful. My apologies for my initial indecision on this.

2. Karsten (kar_bon) is working on a scoring system for NPLB. Please post your opinions and thoughts in the 'statistic pages' thread.

3. We just picked up our 9th top-5000 prime, which moves us into a tie for 8th place among all prime search projects. With ~20 more, we'll be in 6th place. This is where the action is at!

4. We are currently in the process of sieving 300<k<400 for n=260K-1M. The entire range so far is sieved to P=100G with a portion of it sieved to ~P=300G. Look for a 'sieving help' thread late this week where you can help us with the sieving if you like.

On #4, when sieving is complete, this will be an exciting range to test with many more possibilities for varied-type searches. Although we will have a drive #3 for a large portion of it that is similar to drive #1, we will leave ~7-10 k's for individual reservations. Small 'mini-drives' amongst 2 or 3 of you are good possibilites for this range. There are other k's where testing can be started at n=500K or n=600K for those of you who like BIG primes but don't want to wait for the big team drive to get there!

Karsten has completed an excellent scoring system for NPLB. See this thread for info. about how the scoring was arrived at. There is 'bonus scoring' for helping out with some of the lower ranges in drive #2.

See Karsten's scoring page for actual scores. Not used anymore!

Let's get some friendly competition going. Karsten is kicking our behinds right now!

The NPLB Project page is ready with many information and links to the team drives and the scoring site.

see http://www.rieselprime.de/ under the menu 'NPLB'.

have fun and look around there (updates several times a day available)

Nice work Karsten. An excellent analogy of the short project history and conceptualization!

There will be a 24-hour NPLB LLRnet rally this weekend beginning at 7 PM GMT Saturday 2/23.

If you've never participated in a rally before, they are great fun with individuals competing against each other and teams trying to knock each other off! Check out all of the details in the 24-hour rally thread.

Just a note in case you missed it: The rally this weekend will be on port 100 to get ranges of primes filled in.

Everyone bring everything you've got and have fun!

I kindly asked to Kirk Pearson, from distributed Computing site, to add NPLB as a math distributed computing project. Check here. With time NPLB will gain visibility.

After I finish a range and report the lresults.txt, should I delete the old lresults.txt so the file doesn't just keep growing? Is it recommended to report the lresults.txt after every range, or run a couple ranges before e-mailing it? Also, do you have a preference for receiving them by forum or e-mail?

I'm fine with you posting them here or Emailing them. As long as they're not too big, posting them here is slightly preferred but the size limit restricts that for very large results. I can't access my Email from work.

It's best to have separate lresults files if there is a gap between the ranges tested. So if you reserve several consecutive files at once, you can let the results 'pile up' in one file and send or post them all at once. But if you reserve one range, then others reserve some, and then you reserve another range, the files should be separate. If there is a gap between the ranges in a single results file, I have to separate them because there will be other results that come in in between them. I need to be able to see at a glance that we have results files for all ranges.

Please see this new thread about future project direction and server needs.

Sieving for 300<k<400 for n=260K-600K has completed. Drive 3 will start late Friday/early Saturday for the new k-range.

The big file is now prepared and ready. We will be sending a large top-5000 range to IronBits for his new LLRnet server after doing some calculations as to how much will be needed for ~2 weeks including a rally. We'll also post some n=2K files for individual reservations.

This will be an exciting range to process. With < 1/6th as many k's, we'll progress quickly upwards until we catch up with drive 1.

The intent for ~1-3 weeks is to have 3 servers running until drive 2 is complete. One will be processing ranges at n=~340K, another at n=~370K, and the other at n=~290K. So there will be many flavors of primes to search for!

Sieving for 300<k<400 for n=600K-1M is continuing...ETA is mid-late March.

Edit: The drive has started!
