The sieve file for k=173 can be found here: http://www.sendspace.com/file/woyx5r
for those of you who're interested in it. It's only sieved to p=2.3T, but it goes all the way from n=1M to n=2M. I got the k=263 file from VBCurtis and Cruelty, so talk to them if you want to test this k further. It's been a great joy to contribute to this project for the past three years, and I wish everyone luck in their primefinding efforts.

I'll finish 263 to at least 1M. I still have the sieve file.
I am wrapping up a major project that was using ~10 cores for the past 9 months, so I'll be making reasonably fast progress on the halfdozen Cruelty k's I have now including this one, at least compared with 200809. Curtis

It has been a few months since a report, mostly because I tested a 25k block of Adam's 60006200 sieve, which was something like 75000 candidates.
11 1.88M 13 1.80M (no change) 41 1.01M (gap to 1.05, complete 1.051.15M) 45 1.3M (just a few gaps to 1.75M, should be filled in ~60 days) 99 1.6M (more than half done to 2.0M, but with gaps) 109 1.0M (no change) 127 2.37M 131 888k 201 1.17M 211 895k 245 806k 269 900k (no change) 281 900k (no change) I should have all but 245 done to 1M in 3045 days.

Cruelty,
How is the sieve going?

The sieve is running! At 2T, 8.1 million candidates in the file.
Cruelty is sieving at 2T, I'm working on 810T. It's slow going on a core22.2ghz, around 3 weeks per T on a single core. Such a large sieve is very efficient at 8T, I find a factor in less than 50 seconds. To keep this thread less cluttered, I suggest anyone interested in sieving to PM cruelty and I for more details.
