k=2039 tested up to n=3M, no primes, releasing this k.

2017 has already been searched, mentioned already in this thread.

I found a prime for 2001, as mentioned in the primes thread. I have not yet assigned 2021 to a machine, so I'm going to stop my efforts at 2019.

k=2001-2019 are completed to n=1.1M. One prime - 2019*2^1076989-1.
Other k's @ 1.07M.

unconnected · 2013-12-09, 20:24

All reserved k's are completed to n=1.1M. One more prime was found: 2035*2^1094289-1 (329418 digits).

2001 to 2019 are complete to 1130k, except 2013 still in process @ 1115k.

Reserving k=2001-2019 N=1.13M-1.15M

unconnected · 2014-05-29, 06:20

Completed, no primes. Going to 1.2M.

unconnected · 2014-07-15, 14:03

1.15M-1.20M complete (3 primes), slowly going to 1.3M.

unconnected · 2014-09-16, 07:49

1.20M-1.25M completed (1 prime - 2013*2^1209020-1), going to n=1.3M.

unconnected · 2014-12-04, 08:37

1.25M-1.3M completed (3 primes). Releasing all k's.

BTW, there was a gap between NPLB(n<600k) and RPS 11th drive (started from n=666666). I checked this range for k=2001-2049 and found some primes:

2007*2^619422-1
2009*2^640696-1
2007*2^658365-1
2009*2^660920-1
2045*2^662044-1
2013*2^660179-1
2019*2^661337-1
2037*2^628032-1
2037*2^638768-1
