I got the data but haven't looked at it yet. Thanks for sending David.
I'll concur with what Max said. I have no objection to wading through ads when using a useful service for free IF we have to use that service, which we definitely need to in this case. But if the file was < 10 MB, it can be zipped up and sent in an Email so it would be a little annoying to wade through ads for a smallersized file.

For a first try, I'll take a rather small range.
Reserving k=830M to 850M to n=25000

This is running faster than I expected.
Reserving 850M<K<900M to n=25k.

Yes, it's surprising how quickly you can blow through the kranges for base 3 up to n=25K without sieving.
One annoyance here that you'll come across: In addition to k's remaining, you'll need to send me all the primes and those files are huge. What Ian does is Email them to me in k=10M ranges. I think they are in the 1015 MB range each when zipped, which is close to as large as gmail allows. Sometimes he has sent them and I haven't gotten them so I think the time that it takes to send them causes them to get lost in cyberspace somewhere. To be clear, that's all that I need: Primes and k's remaining. No other files are needed. BTW, I've found that running all cores of a 2.8 Ghz I7 will blow through a k=100M range in about 1011 days. As a general rule, the I7 is the equivalent of about 56 cores of a "standard" quad. Gary

Do you need pl_primes.txt or pfgw_prime.log? What's the difference anyway? File sizes are ~5% different. PS.: I tried .zip and .rar, the latter being almost 50% smaller than the first. Is it ok for you to use rar? Last fiddled with by PuzzlePeter on 20110209 at 16:46

Also, for files bigger than 1015 MB, you can use Sendspace to send the files. The incessant banner ads are annoying, but it does work and so far I don't believe they've sold anyone my email address. It's one of the more popular filetransfer services here on the forum since it lets you send up to 300MB. Another good one I've tried is WeTransfer which lets you send up to 2 GB and has much less obtrusive "impression advertising" (though it does require Flash for both the sender and recipient).

I only need the pl_primes.txt and pl_remain.txt files. pfgw_prime.log would have primes that I don't need in it. The script checks for k  1 being prime to decide whether to but the k in the pl_MOB.txt file. So k  1 primes would be in the pfgw_prime.log file, which I don't need. Those primes should be the only difference between the 2 files that you asked about. As Max said, .rar files work for me. I got your two files and see that they are 67 MB each compressed so that works well. I'm glad not to deal with sendspace. Gary Last fiddled with by gd_barnes on 20110209 at 20:17

Completed the above range.
42k's remain. Now, what address do I send the files to?
