Wowthe largestNPLBprime record broken twice in less than a day! :shock: Congratulations on the big prime. :smile: 
Carlos' 331*2^6003391 is actually the biggest found by NPLB, although it wasn't from one of the main drives.
Regardless, a nice run of bigger primes here and it's nice to see the 3rd drive finally find a new one. Gary

Unfortunately we've experienced massive gaps in primes on port 8500, port 300, and my individualk efforts here at NPLB for over a week all at the same time. The gap on port 8500 was the largest we've ever had. Nearly n=5K without a prime for 300 k's! And on port 300, I think that's one of the largest we've had for that port. I'm pouring 80% of all of my resources on port 300 now. 90% after another effort finishes in about 3 days. Gary

I'm pouring 80% of all of my resources on port 300 now. 90% after another effort finishes in about 3 days. Gary[/QUOTE] yeah that 8500 gap was rather disheartening to say the least... I've got the resources on 300 now that 8500 is out of the way. We'll just have to take it day by day and see how the heat factor goes. I've got 3 old heat producers offline now. In another day or two I'll have to take a couple of the dual cores offline as I'll have to move a quad into this room and give the wife back her spare room that she was letting me run the quad in. And at that point I'll be at the max cores I'll be able to run for the rest of the summer on the good days. But it's better than nothing! :)

Thanks for continuing to help Bruce. Early this afternoon, it looked like your resources were just a little more than mine on port 300, which is a great help. I think David's server is just messed up. He's done something to make LLRnet report all composites. :smile: Gary

It would seem that during the time you were doing the greater portion of your LLRnet contribution to this project, we were in a projectwide "dry spot" as far as primes were concerned. Hopefully we're out of that now. :smile:

Yeah, I figured as much, though we all really did seem to be in a bit of a dry spot during that time, so I figured I'd mention that. :smile: 
Only 45 more primes at most needed to overtake PIES for 2nd place! :smile: Theirs are now dropping off at a rapid pace and they currently have 3 primes >= 4990th place. We'll have one drop off in the near future but none for a while after that.

Finally! It's been nearly two months since my last prime, and I "should" find a prime about every month at this size. This was the largest gap (in both time and n/digits) between primes I've had. :george::wacky::grin::grin::grin: July was my first month since I started NPLB that I didn't get a prime. With 159580 digits, this is my first prime that will be placed on the short list once verification is finished.

Gary[/quote] The "short" list is every prime over 150,000 digits, plus smaller primes that are of special, interesting forms, while the normal list is the top 5,000 primes, plus smaller primes that are of special, interesting forms. With current primes, that means it's the top 1543 primes, plus special ones.

Unfortunately, that's a lot less than it "should've" had. Assuming 700 avg k 2 base 513,250 avg n 5000000000000 sieve, and 128500 pairs (I got this from the number from my n=600 range pairs, even though they're a good bit higher, multiplied appropriately and increased by 2 to make a round number...is the exact number available?), 18.810 primes are expected.

Not as drastic as the LLRnet servers, but an annoying amount (such as the gap that caused me to have my first primeless month in July).

Actually, I've basically only run them during rallies, and I've found one prime through them. I'd guess that's about average (or above average), considering the number of rallies. I meant the primes NPLB as a whole has found, LLRnet in particular since that's what a vast majority of NPLB is done on, has slowed down disproportionately.
