- - **RPS 11th Drive: Search for more megabit primes**
(*https://www.mersenneforum.org/showthread.php?t=16011*)

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. |

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 |

708-712 complete - 3 primes
taking 714-718 |

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... |
