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 smaller-sized 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 k-ranges 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 10-15 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 10-11 days. As a general rule, the I7 is the equivalent of about 5-6 cores of a "standard" quad.

I am running a Q9300 at stock speed (2.5GHz) on this. One core does 10M in 3 days, which would be 100M on all four cores in about 8 days. Is there something wrong with my ranges? Or will running four tasks slow down the machine? I triple checked my entries in the script already...

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?

Yes, it should be OK to send him .rar files. (IIRC, he installed WinRAR a while back when I tried to send him a .rar file once.)

Also, for files bigger than 10-15 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 file-transfer 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 may have been slightly mistaken on 10-11 days to run a k=100M range on an I7. That was a rough guess from memory. 8 days sounds about right.

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 6-7 MB each compressed so that works well. I'm glad not to deal with sendspace.

Peter has completed k=830M-850M to n=25K and has sent the files to me. 104 k's remain.

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