370,000  400,000 complete (No Primes) residue sent to Kosmaj

grobie is working on 400450.
I'm still sieving the rest, currently at p=6.2T 
n=429318 Prime Confirmed

[QUOTE=grobie]n=429318 Prime Confirmed[/QUOTE]
400 to 450 complete 1 confirmed prime. 
The 450k2M range is now sieved to 8T. There are 81632 candidates or 52.67 per 1000 n's. The prevailing opinion is that g167 most likely checked the range to n=601158 where he found a prime. Therefore, I'm releasing both 450500k files which have a certain doublechecking "flavor" and files from 600k where a new prime is more likely.
This is a long term project and we are not in hurry. Feel free to check one of these files as you like. But I'd like to propose the following: i[U]f/when somebody finds a prime at n>600k he is obliged to test a few n<600k files if by that time there are still some left unprocessed[/U] :smile: BTW, here are FFT lengths used by LLR (versions 3.6 and 3.7) to test primality of 17*2^n1 (output of Thomas' fft_len) on Pentium4 cpu's: [CODE] fftlen nmax  24576 454369 28672 528898 32768 604426 40960 751484 49152 895042 57344 1040800 65536 1191057 81920 1480573 98304 1765088 114688 2052604 [/CODE] 
Taking 600605.

I'll take 605610 and 610615

Taking 615620

Huge congrats to Alex on the first NEW k=17 prime found by RPS:
[B]17*2^6053941[/B], 182243 digits :w00t: :cool: I have to say I didn't expect anything before 620630k, even higher. :surprised This is now a oneway street, and primes are straight ahead! 
Thanks :george:
I didn't expect a prime so early myself :grin: Well I guess you can already prereserve 450460 for me then :razz: 
All right, 450460 is yours! :smile:
I'm also taking 620625.
