Range reservation thread (n=390000)

[Oddball]

Post in this thread to reserve a range for LLR'ing. Report results the same way, and include any primes you may have found.

Range		Reserved by		Status		Primes found
0.0M-0.3M	Oddball			complete	0
0.3M-0.5M	Oddball			complete	0
0.5M-1.0M	Mini-Geek		complete	0
1.0M-1.2M	Oddball			complete	0
1.2M-1.4M	Historian		complete	0
1.4M-2.0M	Oddball			complete	0
2.0M-3.0M	rajula			complete	0
3M-10M		Lennart			complete	0
10M-12M		Oddball			complete	0
12M-20M		Lennart			complete	0
20M-22M		rajula			complete	0
22M+		available

The sieve file for k<10G (sieved to 8.1T) is located here:

A core 2 quad at 2.4GHz can test four candidates in five minutes if all four cores are used for this project. A range of 1M contains about 500 candidates.

k=500k-1M is done. No primes. Results attached.

[Oddball]

The results from 0-0.5M are attached, in case anyone's curious. Just to clarify, 0-0.5M means k=1 to k=500000 in the stats page. So a reservation of, say, 1.7M-2.1M would be reserving k=1,700,000 to k=2,100,000.

[Historian]

Range 1.2M-1.4M complete, no primes, results attached.

I haven't done any sieving on 10G-150G, so no work was duplicated.

As far as LLR testing goes, I've extended my range from 1.4M-1.7M to 1.4M-2.0M. 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.

[Lennart]

Test done 3M-10M & 12M-20M No Primes

Lennart

[rajula]

Done with 2.0M-3.0M. No primes.

I would like to reserve 20M-22M.

[rajula]

Done with 20M-22M. No primes.

[Oddball]

It's been quite a while, but 10M-12M 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 n-range, which has a much greater sieve depth and the advantage of testing lower k's.
