RPS 11th Drive: Search for more megabit primes
 
We are starting our 11th Drive, featuring all untested Ks in the 2000-2300 range, the total of 124 of them. The following 26 Ks are EXCLUDED:
2055, 2065, 2073, 2085, 2087, 2089, 2093, 2109, 2115, 2123, 2125, 2145, 2151, 2153, 2155, 2175, 2177, 2179, 2185, 2187, 2199, 2203, 2235, 2265, 2293, 2295.

Files have been prepared by Thomas, thanks!

[B]Update-1 (Sep 14, 2011)[/B]: k=2039 found to be already tested to n=1M, removed from test files.
Continuing with 123 Ks.

[B]Update-2 (Jan 9, 2013)[/B]: At n=1010k, the following 3 Ks were added: k=2039, 2055, 2085.
Continuing with 126 Ks. k=2039 tested in the 1000-1010k range by Thomas.

[B]Update-3 (Aug 28, 2013)[/B]: We are stopping the team drive at n=1025k, moving the following high weight 13 Ks to the new 12th drive: 2043, 2049, 2061, 2079, 2085, 2103, 2127, 2205, 2211, 2253, 2259, 2271, 2289.
[B]All other Ks are now open for individual testing.[/B] Please report your reservations and your progress in this thread. Thanks!

Test files in this drive, and test files in the following drives:
7th, past n=1M
8th, past n=1M
k=17

are updated using the latest Psieve files released on July 31.
Othe drives will be updated in the next 24 hours from now.

Thanks to Thomas for creating the files! :smile:

Kosmaj 2011-09-13 10:37

We also uploaded the new version of your 708-712 test files, if you want to update them.

Thanks for the offer, but I'm done with them.

Thomas11 2011-09-13 17:14

I just noticed that [B]k=2039[/B] has already been tested by James P. Burt up to n=1M. He reported the prime [B]2039*2^841312-1[/B] in 2008.
So we will remove this k from the drive.

Kosmaj will replace the input files on the server as soon as possible...

BTW.: We'll keep the other k=2029 for which pb386 just hit an already known prime (2029*2^673583-1) in the drive, since we do not know how far it was tested.

Kosmaj 2011-09-14 02:47

11th Drive test files updated as Thomas said, by removing k=2039.

The following drives are now all updated using latest Psieve files of July 31, or later.
1st Megabit
2nd Megabit
k=5
k=15

Sieving depths (Thomas, please confirm):
p=100P (=1e17) for all n<3M,
about p=30P (=3e16) for n>3M, in our case k=5

Yes, these are the current sieving depths.

I got a reply from justinsane, the finder of 2029*2^673583-1, stating that he can't tell anymore, how far this k was tested.

So, we'll keep it in the drive...
