Thanks for the info (I did not find a reservation or statusupdate for the k with a quick search). I was planning on putting one core to crunch one lowweight, already sieved, lown k, but perhaps I'll dedicate also that core on running ECM (stage 1) on F12.
I unreserve the k=9913 then and continue slowly just with 45045. (Maybe http://www.rieselprime.de/ could be updated on k=9913). edit: on a second thought: I could reserve k=3907 (if it is not also tested to the 3M heights.. It is not complete obvious for me where I should check the reservations) Last fiddled with by rajula on 20140630 at 12:48

k=3907 is reserved by FreeDC Prime Search but it has been a dead project for the last year.

Did you mentioned this effort in this Forum? If so, please give me a link, so I can insert it on my page. Thanks.
It's not reserved on my pages because FDC is dead for a long time, only primes found by Burt were inserted. Last fiddled with by kar_bon on 20140701 at 07:47

Can they come from some 4^n or higher "crus"? As it seems most of the n's are also even, and most of the k's are 2 mod 4?
