Flatlander stopped and released k=55 at 946k, and k=147 at 600k. He sent me his sieved files and they are available on request.

Cruelty- I have LLR running on 19 cores, with 4 cores as sievers. All LLR machines are P4 or Athlon64, save for a single Core2 at home (at 2800 mhz).
Average speed is around Celeron-2.2Ghz per core, so roughly 40Ghz of LLR going, most of them 24-7. I'm putting multiple cores on k's I can complete this winter (93 and 197), so that I can move 5-8 cores to the k's you pass on to me by spring. With 99 and 45, I'm just trying to keep up with Sheep's sieving.

Reserving k=161 and 163 from 500k.

Rob informed me that he tested k=243 to 1.15M. He stopped there and is releasing it.

AES 2008-02-29 04:32

k=9 tested from n= 850,00 to 1,200,000
k=33 tested to n= 900,000
k=71 tested to n= 833,000
k=107 tested to n= 641,000
k=103, 143, and 167 tested to n= 684,000 --thanks for the help VBCurtis

Reserving k=165 from 637k.

Cruelty 2008-03-01 19:22

k=221, 233, 263, 283, 299 tested till n=740000.
I am releasing k=221 - Curtis should have a priority on further reservation of this one.

Reserving k=157 from n=500K. :smile:

VBCurtis 2008-03-15 09:15

As Cruelty suggested, I'll take 221 from 740k where cruelty left off.
Status update:
45 1050k -> 1.2M now. Sheep tested 1.1M to 1.2M for me-- thanks!
119 500k -> 1M now, unreserved.
197 1.03M -> 1.1M now.
201 900k -> 950k now.

93 going on many cores, but there are holes all over the place, so a large range will complete in a few weeks.
