There is no need to test. It can be easily proven that all primes > 3 must be either p==(1 mod 6) or p==(5 mod 6). Proof:

p==(0 mod 6) is always divisible by 2 and 3
p==(2 mod 6) is always...

There is nothing in writing or set in stone. With the non-top-5000 stuff now closing in on completion, the main objective this year would be to keep k=1400-2000 well ahead of the 5000th place prime....

ROFL. When I took over the server from Ironbits, I got 2 more Intels; a quad that is now the server machine and an I7 as my new personal Windows machine, both running at ~2.9 Ghz, so I now have 12...

Max, when you get a chance, can you post a new thread with an announcement for the rally? It should be virtually identical to the last one. Thanks.

I'm in favor of starting a team sieve on k=400-1001 right away with GPUs if Bruce and Vaughan are available with them. From what Max is indicating, 9 GPUs would do amazing things with such a sieve....

I posed that question in the LLRnet servers thread. There was an Email exchange between Max and David (Ironbits). The stats database may be in the process of being moved. Hopefully Max can answer.

As Max implied, I'm sure this is OK. The timing difference between the smallest and largest exponent for the 12th drive (port G7000) is fairly extreme. A test at the high end of the range should take...
