 2014-12-13, 15:29 #539 KEP Quasi Admin Thing     May 2005 2·3·7·23 Posts I'm throwing 8 cores on R3, so I'm making this reservation: Starting new range: minK= 13000000002 (13G) maxK= 21000000000 (21G) I'm going to use the starting up bases script to n=2500, using "pfgw_win_3.7.8_20141127". (ETA for this part is about March 1st 2015). From n=2501 to n=25K, I'm going to use a sievefile and primality test with LLR 3.8.13 (using LLR's StopOnPrimedK=1). Regards KEP
