Happy new year, KEP. Great job you have done there! The ck from R3 is ~63G, but take a look at S3. 125050976086 is a "bit" more. ;) I will focus more on S3, S7, S15. The range 25G63G is still at n=25K. Yep, a large amount of work. ;) About the sieving: S66 is needs some time, but after this (and pepi´s work) is done, I´ll take an Range for sieving. Let me know which pmax you want. ;)

Yes, there is still about 56 billion k's untested for S3. If you want to start up a range for k>13G, I'm willing to teach you how to use srbsieve. If you know how to use NewPGen, then everything will work out just fine. Of course Gary has to agree with you on how to do the starting up of untested ranges. I however am willing to help you get it right. Regarding pMax and sieving, try and ask here in the forum, before starting. Maybe VBCurtis who has done the most of the n>100K sieving, would have a very great suggestion for you on how to use your ressources the best

Is this one month per core per 1G? I would think that it would take longer. I'm considering taking a range of R3 from n=25K to 100K. If I could get a good estimate for how long this would take on a single core, then I might reserve a few G.

Correct my handwavy guess is a (haswell or better) coremonth per 1G from 25k to 100k. It has been a very long time since I've actually done such a run, so I might be off by a factor of two; you could always run for a coreweek and extrapolate to decide whether you feel like doing 1G or 5G?
Note that testing a range of exponents scales for R3 close to linearly with the exponent, rather than quadratically (more accurately something like exponent ^ 1.4 scaling); so many k's are removed that testing 5055k is just a bit over twice the time of 2530k. I think 25100k testing will remove around half the k's. Disclaimer: this is all recollected from circa 2013 when I studied such things.

Testing R3 from n=25K100K actually removes a little over 2/3rds of all k's. The scaling seems accurate to me.
