Range reservation thread (n=390000)
Post in this thread to reserve a range for LLR'ing. Report results the same way, and include any primes you may have found.
Code:

A range of 1M contains about 500 candidates. Old posts in this thread can be found here: http://www.mersenneforum.org/showthread.php?t=13396 Last fiddled with by Oddball on 20100729 at 19:26

The results from 00.5M are attached, in case anyone's curious. Just to clarify, 00.5M means k=1 to k=500000 in the stats page. So a reservation of, say, 1.7M2.1M would be reserving k=1,700,000 to k=2,100,000.

As far as LLR testing goes, I've extended my range from 1.4M1.7M to 1.4M2.0M. No primes were found, results are attached, and the first post has been updated. I'll wait until a deeper sieve depth is reached before reserving any more ranges. Last fiddled with by Oddball on 20100512 at 05:32

It's been quite a while, but 10M12M is finally complete. Results are attached, and no primes were found.
I'll unstick this subproject since it's no longer a top priority. The focus should be on the variable nrange, which has a much greater sieve depth and the advantage of testing lower k's. Last fiddled with by Oddball on 20100727 at 17:55
