Proth Prime Search

We are making excellent progress in both the primality testing (LLR) and the sieving. The only thing missing are the "new" primes. :( However, they will come in time...as n continues to increase. Currently, the sporadic non-searched areas that we are covering are yielding no primes. We expect to find many "new" primes as we reach more non-searched ranges.

To help us get there, we'd like to propose some end of year goals.

Proth Prime Search (LLR)
22 Nov 2008 - n=365K

• goal n=500K
  
• advanced goal n=550K
  
• very aggressive goal n=600K
  

Proth Prime Search (Sieve)
22 Nov 2008 - p=200T

• goal p=300T
  
• advanced goal p=350T
  
• very aggressive goal p=400T
  

Thank you for all your help! May everyone find lots of primes and factors in the upcoming holiday season. :)

n = 500K might be realistic, but you will need to almost double the number of horsepower to get there by the end of the year (based upon a rough estimate). Personally I'm hoping that you don't quite get there so that Proth Search ranges reserved between 500K and 600K can be completed by those who have those ranges reserved.

If you believe that you will get to n = 600K within the next two months, let me know so that we can coordinate. Another decision must be made as to how to proceed beyond that. If you really think that PrimeGrid can get to n = 600K so quickly then maybe it should reserve a larger range of n, such as up to 800K.

Update

The sieve is looking very good. Unfortunately, the LLR seems to be struggling. There was an excellent boost with the Challenge. However, since then we've been falling behind.

John-- I missed the start of the challenge so I decided to stick with the PPS LLR and try to help get the target 500K but I keep running out of work---

Could you fill the bin up please-- Thanx

Well, time has run out. We are 1 out of 2 for our goals...with the most important one being achieved. :) Nevertheless, we are advancing quite nicely on both fronts.

Thank you for all your hard work.

Nope! :( Currently at n~488K

I'll post when we reach 500K so we can see how far we missed it by. :)
