I am at n=10K now, two more primes:
101*698^68861 53*698^73041 Now for some more sieving...

Welcome to CRUS Mattyp! As long as you are aware that your reservations will take several CPU months, it seems fine to us. You can use srsieve followed by sr1sieve for sieving and either PFGW or LLR for testing. If you have any questions, please let us know. Good luck!

By the way, in case you're not familiar with it, such a range (i.e. >2 k's) would be best sieved by srsieve to start (if the sieve wasn't started already) and then sr2sieve for the sieving (for 1 or 2 k's, sr1sieve is usually best). Between running srsieve and sr2sieve, (or at any time, really) you might also want to run this hiddenpowers script (be sure to read the documentation and note the sieve file must be NewPGenlike, i.e. each line being like "k n") to remove some numbers that have algebraic factors and can't be prime.

I have a quad core, at 3.4 GHz, running 24/7, but could put on an extra 4 if it comes to it. By my estimates (very rough estimates), the multi k range will take around two months, possibly less if I find many factors. Thanks for the tip about the script. Wouldn't the factors just be found by one of the sieving programs anyway?

As a rough estimate, I would say that your 2 efforts combined will take ~1 CPU year (possibly longer) or ~3 months on a quad running 24x7. These larger bases take much longer at the same nrange than much smaller bases.
Tim, since he is running the Sierp side, there are unlikely to be any k's where algebraic factors can remove some of the n's. The only small exception, since neither base is a perfect cube or higher power, would be if any of the k's were a perfect cube or higher power (upon a quick glance, I don't see any). Personally I wouldn't suggest that he mess with it until he's run the conjectures a little more. Mattyp, one hint that I always give new people: It's very easy to reserve way too much and then get bored before the effort is done. Please do not bite off more than you can chew. It's better to start out small and work your way up to larger reservations. I'm not making a judgment as to whether yours is too large; it's just a little friendly advice. :) Last fiddled with by gd_barnes on 20110123 at 19:24
