First of all, these numbers have already been crunched before, so we will probably find relatively few new primes (because the only primes we will find are ones that were missed the first time around). However, in previous doublechecking efforts for the 300260K will be handled separately, as for those we have first-pass residuals on file from NPLB's testing of that range.)

If your results files are too big to attach here, you can email them to me at max@noprimeleftbehind.net, though I'd rather if results were attached here whenever possible. Let's have fun and plow through those doublechecks!

We haven't checked for known primes yet--I'll let Gary do that.

As for your machine: Okay, sounds good.

If you've run a torture test for 16 hours without a problem, then you shouldn't need to lower the CPU speed, though of course it wouldn't hurt.

Well, guess what I've been doing the last 2-3 days? I've been bringing Karsten's k<300 page up to date and making it non project-specific.

Since Kosmaj is hiding the RPS k<300 page due to the perception of people picking up the testing ranges of k's for their own benefit, something that Karsten, Anon, and I vehemently disagree with, I will make it available for viewing on request in a PM. I still have some links to add but the info. is 100% accurate and up to date as of early this morning.

You'll be able to see the known primes for your k's < 300 in full color. lol

 2008-03-25, 17:12 #8 gd_barnes     May 2007 Kansas; USA 5·2,017 Posts In suggesting doing this by k, I has assumed that the files would be sorted by k primary and n secondary. I would now suggest that people wait until they are done with their entire 3k file before posting any primes. We'll then have to sort them by k to make it easy to verify them. The best alternative is probably for people to attach their primes files here after finishing each file to avoid myriads of primes posts. Thanks to everyone for hopping in on this. I'll move 3 cores over to it around 4/1 after sieving of k=300-400 for n=600K-1M is complete to P=14G. Gary

Yes, I agree--we should post primes files here as well as lresults files. Since there's a limit of one attachment per post, just pop them into a zip file and you'll be all set.

As for sorting by k primary and n secondary, unfortunately srfile can only sort by n and not by k, so thus the files are sorted by n. However, as you were saying, as long as we just post the primes files too at the end of the range, we'll be fine.

Srfile can write out by k using the -g switch. This is ideal for what we want. You then just do the copy command to copy 3 files at a time into a 3k file for LLRing. There's two extra instances of the header in the file but LLR doesn't care.

Obviously you're sorting by k in some manner. However you got it down to 3k files is the way to get it down to 1k files and then combine them with a copy command into one file.

Excel can also be used for sorting small files like this but would take quite a bit longer with 167 or so total 3k files.

This is just for future reference. No need to mess with it now since people will post files of primes at the end of a range. It's how I divided k=300-1001 for n=50K-100K up into 50k chunks for splitting amongst 7 machines.
