Team drive #9 k=10052000 n=50K350K
This is team drive #9 for NPLB. We will be searching all k=10052000 for n=50K200K and k=14002000 for n=200K350K. Karsten has created a web page that shows details for the drive here.
An LLRnet server will be processing most of the range. For general info. on setting up and running the server see this thread. Server info. is: server = "nplb.ironbits.net" port = 9000 For this drive, there will be no top5000 primes. For ranges run on the server, the admins will take care of showing all primes in this post. Please post requests for manual files and we will send them to you. For manual ranges, please wait until you have completed your range and then post primes in THIS THREAD along with your completion status. The drive will be searched by kvalue to make it easier for posting the many small primes that will be found. All primes found from drive #9 for k=10052000 and n=50K200K by k and nvalue: primes k=10052000 n=50K200K All primes found from drive #9 for k=14002000 and n=200K350K by k and nvalue: Code:

Excellent. OK, everyone. I just need to apply the P=1.4T1.8T factors to the file, which I will do shortly. How would we like to proceed with the n=50K200K effort? I had previously recommended that we search by kvalue. If we do that, we'd post files, 13 k's at a time in sequencial order similar to our doublecheck drive, and people can take as many as they see fit. Alternatively, we can try loading a very small nrange for the entire set of k's in nvalue sequence, say, n=50K52K, and see how it handles such fast tests. A second alternative might be to load 23 k's into the server and observe how the server performs in kvalue sequence over the entire n=50K200K range. In a synopsis: 1. Test manually by kvalue. 2. Use server on a small file sorted by nvalue. This would be the most stringent test on a server because all tests would be very fast. 3. Use server on a small file sorted by kvalue then nvalue. This is not as stringent of a test since all nvalues within the range will be tested. Gary Last fiddled with by MyDogBuster on 20090323 at 06:03

Of course, if we're giving the server ranges in terms of n, we'll probably want to do the same for manual ranges to avoid confusion. That shouldn't be too bad, thoughsorting by n worked pretty well for the 8th Drive on this same krange, so this should essentially be the same thing except that we'll be giving out larger files to compensate for the smaller tests. BTW, Gary: if you're having a hard time dealing with the huge sieve files for this effort in a text editor, try popping it onto one of your Linux machines, and then use the terminal to run the command "split l 500000 [name of sieve file]". It will then split the file into nice easy chunks of 500,000 lines eachquite manageable. (It will originally call the files generic names such as "xaa", "xab", "xac", etc., but you can of course rename them however you like.)

http://www.vim.org/download.php I like #2, however, send IB8000 that entire range and let's just eat it up. Last fiddled with by IronBits on 20090105 at 23:03

I know this is long but I'd appreciate it if people could read it all the way through because it goes "one way" and then the "other".
We need to think this through. You remember the discussion we had before? Karsten is not going to like us because he'll constantly have to be entering primes all over the place on his pages. That is why I had suggested sorting by kvalue to begin with on the low nrange, i.e. n=50K200K. People had initially agreed searching manually by kvalue was the way to go so we now have 2 schools of thought. Let's look at what we have here: 1. There will be 10's of primes coming in very rapidly and David, it will stretch your primes listing to a very long length on your web page as they come in. 2. If people post them all in our primes thread as they come in, it will quickly innundate our primes thread. 3. It will be extremely easy to miss a prime or two because we won't be associating primes with specific kvalues, only nranges, and there will be so many of them. I know it sounds like I'm trying to talk everyone out of it but not really. I just want to make sure everyone knows the facts of doing it that way. If people think it would be more fun to search by nvalue, here is what I would suggest: 1. Load n=5K or (10K or whatever we think is best) ranges into the server sorted by nvalue. The range can be decreased as we move higher. 2. No one report any primes anywhere until the entire n=5K range is done. 3. When we have determined that the nrange is complete, Max or I check the results files, sort the primes in them by kvalue, and post them in our primes thread, showing who found them, all in one post for each nrange. In addition, as usual, they will be put in the 1st post of the drive thread in decesending nvalue order, also showing who found them. This creates a little more admin work for us but I personally don't mind if Max doesn't. IMHO, it's the only way we'll avoid missing primes. It's just too easy for otherwise "passive" searchers to accidently miss reporting nontop5000 primes. It will also make it relatively easy for Karsten to post the primes on his k=3002000 page. Karsten, if you're around, you can give your opinion here too. Gary Last fiddled with by gd_barnes on 20090105 at 23:40

Whatever, however, you want to do it is fine by me.
I was just trying to help everyone out by avoiding the tedious manual reservations thang. Just load up the server with what ever you like, if folks want to come in and cache 100s at a time, that's fine by me, the server seems to handle that with out a hiccup. We'll never know what the limits of the server are, if we don't push it a little harder... I have no preference to loading it up by K or N, what ever suits you suits me

Everything eventually gets tested either way so why create loads of unnecessary work. Oops I almost forget, NO MANUAL RESERVATIONS. To hard to handle. Oops #2. I would love to reserve a k from n=50K to n=1M. Last fiddled with by MyDogBuster on 20090105 at 23:56

Oh, and by the way: sorting by k should still be just as much of a stress test for the server. Maybe not quite as prolonged of a stress test, but that shouldn't make a differenceit will still tell us unequivocally whether the server can handle n=50K tests.

Heck, I'll offer to save you all the trouble and reserve that whole k/n range and let you know when I finish it.
Did you want me to turn off autonotify, and not display found primes on the web page, for this range on port 8000? Last fiddled with by IronBits on 20090106 at 00:21

I will also vote for #3 mainly because it would save us a little admin time and Karsten a lot of admin time. It would also spread out the average prime rate found instead of having tons of them at first followed by less of them later.
David, if we went that route, you would still get the entire range loaded into your server; just processed in a different order. If we did #3, I would still suggest doing what I suggested above with Max or me posting the primes found sorted by kvalue in the primes thread. Instead of every n=5K or 10K range, we just do it after about every 25 k's searched. The admin time it would save for Max and me is us having to sort it by kvalue before posting so not a lot. But...the admin time saved by Karsten would be large. He would only have to update the nrange searched on each k one time each. We have 2 votes each on #2 and #3. More opinions still welcome. Gary
