That's a bummer on having to go to 32 bit. Thanks for the help.

I'll go ahead and reserve P=8T-10T and put it on 2 cores. I'll see if I can get us up to P=12T by mid-month so that we can get the Riesel drive started again.

P=8T-10T is complete. Reserving P=10T-12T.

BTW, quite some time back, I posted the file sieved to P=8T in the first post here.

If anyone is interested in helping, we can go ahead and sieve this range to a few trillion above P=12T. That's optimal if it takes us at least a year to finish testing n=200K-300K on both sides. Since n=300K is n=1.2M base 2, it's quite a bit of work for 43 k's, although the avg. k is very low weight.

P=10T-12T is complete. The sieving effort is paused as we break off and test n=200K-300K.
