You are hilarious!! That's awesome if you add a new quad to the mix. Heck, add a few quads! lol I am at k=10M on base 3. Now that I'm back from my trip and the NPLB rally is over, I'll put a core back on it after I get the correct motherboard on my final quad, which should ship Tuesday and I should have installed by Thursday.

Due to all the recent interest in Sierp. base 3, I've decided to start a team sieve for the 36 k's remaining for k<10M at n=25K. I know the original plan was to wait until we had ~100 k's left at n=25K and then do a big sieve on that, but at 36 k's we've already got about the same number of k's that we did in the Sierp. base 6 drive, which was a pretty good size. So, I'm thinking that it would be a good idea to get started on sieving these k's sooner rather than later.
I'll start the sieve with srsieve soonthe exact k's that will be sieved are: 2930054, 2949008, 2980832, 3159992, 3234118, 3891872, 3938414, 4273396, 4660218, 5574644, 6123394, 6363484, 6752308, 6859514, 7081006, 7111766, 7468382, 7865238, 7879512, 7969792, 8058998, 8090242, 8167364, 8182316, 8603464, 8828234, 8911036, 8990238, 9043382, 9095488, 9240646, 9294874, 9483244, 9572848, 9690724, and 9987808. I'm thinking that we should sieve them for a range of n=25K200K. You can expect to see the teamsieve thread posted soonit will be run very similarly to the Sierp. base 6 team sieve. If there are any objections, just give a holler. Last fiddled with by mdettweiler on 20080505 at 19:57 Reason: typo

@ Gary: Thanks and there might come more Quads depending on what my financial advisor (me) and the departement of defence (my computer store) can come up with of various offers tomorrow local time or ~10:30 hours from now.
@anon: Why... oh why don't you ask Gary for the 69 k's that I shipped him and start a sieve for these 105 k's... of course if Gary doesn't mind... I can send them to you if no one objects and you're interested Have fun anyone!

I think we're jumping the gun here on a team drive. It would be messy to include those 69 k's for k=110M120M in a team drive with the 36 k's for k<10M. If we're going to do a team drive, let's keep the krange contiguous. Also, I'd still just as soon hold off on a team sieve for Sierp base 3 until we have at least 100 k's remaining in a contiguous krange. It's simply a matter of longterm sieving and testing efficiency, namely sieving. If you went the slippery slope, we could hold off until we had 100000 k's remaining for max longterm efficiency but we need a happy medium where we're finding some large primes along the way, which is a little more fun for people. Another reason for holding off is that we haven't had much activity on Sierp base 6 recently nor on any of the team drives. We may get the sieving done and it'll just sit there with little work. I plan to put 12 cores on Sierp base 6 later today. Redistributing the work on my machines is task 6 of my 8 tasks today. I'll tell you what: I'll unreserve k=30M100M for Sierp base 3. I'll admit I bit off a bit too much there. Once I hit k=30M (I'm thinking about 24 weeks on 1 core), we can start a team drive on those k's. KEP or Anon, if you want to reserve parts of k=30M100M for Sierp base 3 for PFGW testing to n=25K, go ahead. I think that would be a better use of resources at this point than starting a team sieve.

No big dealI only did a negligible amount of sieving work, so I just tossed what I had done into the bit bucket. As for testing parts of k=30M100M with PFGW: well, I would gladly agree to do some, except that I haven't been able to get ahold of a Linux PFGW version. So far I've just been using WinPFGW in a virtual machine, which is no big deal for little things like verifying PRPs, but will be a serious slowdown for a large effort like Sierp. base 3. So, I guess I'll just stick to alreadystarted bases for now. (We need to bug Jean Penne to give LLR 3.7.1d an option to accept ABC2 input filesi.e. the files we use with PFGW to make it stop searching a given k when a prime is found! )

Keep your sieved file. We'll sieve the rest of the k's < 30M (or whatever) that are remaining up to your sieve limit and then combine them. No reason to resieve those 36 k's. Yeah, I wondered that about PFGW. Let me know if you find a Linux version of PFGW that would be easy for a Linux novice to load on a machine. The cores that I'll put Sierp base 3 on is my Athlon laptop. Not a great tester but it's OK for low nranges and it's a dualcore so I'll put both on it. It's doing filler work on port 300 right now and I don't have any sieving that I need for it to do right now. As I told KEP, I can't do any more responses in forums today except perhaps questions/comments on Sierp base 6 sieving/team drive, which is task 3 on my 8 tasks today. (lol) Back to web page updating... Gary

I have moved all posts related to base 3 to a new stickied thread.
There will be some signficant changes to the k's remaining for Sierp base 3 for k=110M120M. Info. will be in the new thread shortly.

I have an exciting result after having been away from home for a few days. A new phrot discovery:
958*11^300544+1 is PRP. (t=9903.68s) I am trying to verify with PFGW. I'm uncertain as to how long the verification will take. If this holds, it will be the first megabit prime found with phrot and AFAIK, the first megabit prime found on PowerPC. It will also solve the Sierpinski problem for base 11. Thanks to Phil for his software.

Oh my word! That is HUGE!! A huge congratulations and thanks from all of here at CRUS!! Good luck on that verification! You must have had some serious firepower going after that one. I only showed you at n=200K as of April 24th! For everyone's reference, that's 2 conjectures now proven by Rogue! It's nice to finally knock out one of the many stubborn Sierp conjectures that have just 12 k's left. Gary
