Currently 3 "regular" drives (for Riesel base 16, Sierp. base 16, and Sierp. base 6, respectively), and two "mini" drives (Sierp. base 3 and Riesel base 3).
P.S.: We've currently got an LLRnet server running for Drive 3 (Sierp. base 6), at crus.ironbits.net port 6. Recently that server has been completely idle; we could always use some help there. Last fiddled with by mdettweiler on 20081215 at 21:18

Unbelievable! OK, how'd you do that? You're starting to scare me a little. Have you solved the mystery of where primes will be? lol Well...actually, I was wondering how you were searching base 45. Unless you put a whole bunch of firepower on it, you couldn't be at n=65K on all of the k's yet starting from just n=10K. Anyway, congrats on something that I don't have yet...a nonpowerof2 top5000 prime! Gary

A couple of things on your prover code: 1. LLR cannot prove a nonpowerof2 base prime. If you tested it using LLR, then, yes, you should have LLR in the prover code but you also need to add "OpenPFGW". (I'm assuming you used PFGW to prove it.) 2. I thought you were going to search with Phrot since it is much faster. If you did, then LLR would need to be changed to "3Ps" in your prover code. Once again, it cannot prove a nonpowerof2 base prime so like in #1, you'd need to add "OpenPFGW". For an example where Max found a base 23 top5000 prime using Phrot, see his prover code p238. If this was an isolated prime that you just happened to find, I'd say don't worry about it. But since you'll likely find several top5000 primes for all of the base 45 k's (or base 6 or some other base), I'd suggest Emailing Prof. Caldwell and having him make one or both of the changes above. If you searched using Phrot, my guess is that he will ask you to create a new prover code and then will move your prime to it since LLR prover codes start with an "L" and Phrot codes start apparently start with a "p". Eventually your code L669 would be deleted by their system after it doesn't have any primes for a period of time. Alternatively, if you searched with LLR, then I'm sure he'd just add OpenPFGW to L669. Gary

I'm searching individual k's to 100K. I sieved all the k's from n=10K500K up to 10T max. Now I'm using the individual k files to phrot to 100K. I have 4 cores banging away. I didn't like the idea of doing all the k's at once to 100K. Quote:
At least I got the srsieve, CRUS and my name right. 3 outta 4 ain't bad for an older guy. lol

Proof software: OpenPFGW Additional credits: CRUS, Srsieve, 3Ps (Note: 3Ps is the code for Phrot. The reason why it's called this instead of just Phrot is because Phil, the guy who made Phrot, figured it would be simpler to combine it into one prover code along with two other lesserknown primefinding programs that he's made. I think it stands for "Phil's Prime Pack" or something like that. ) Last fiddled with by mdettweiler on 20081224 at 07:20

Okay, glad to hear that it's getting fixed. And, don't feel bad about itmessing up in some way when reporting primes is a very, very common mistake and has probably happened to at least 75% of us here at some point.
