I just noticed that k=2039 has already been tested by James P. Burt up to n=1M. He reported the prime 2039*2^841312-1 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

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...
