[quote]Ian, if you find it useful, I reposted your reserved file below the reservations with all of the k's removed that you found primes for n=50K-60K. I didn't remove k=54320036 so there are a total of 109 k's remaining in the file.

[/quote]

Thanks, but I removed the k's myself before I started. (k=54320036 is still in there)

If you want to post the rest of the Drive's pairs, I'll take the whole thing to 100K and thus finish this drive. It should only take me ~ 20 days.

OK, I'll post the rest of the drive in one BIG file sometime late Sunday.

Keep in mind that the testing time at n=100K is double that at n=70K. You have large enough resources that even if you hadn't considered that, I'm sure it won't make much difference.

I already have a fully sieved file from KEP for k=100M-200M for n=25K-100K for this base. So within a few days after you reserve the "BIG" file, I'll start "Mini-drive II - Sierp base 3".

For this next mini-drive, I'm going to run it differently. We'll be searching by k-value but within larger n-ranges and the files will be sorted by k-value. For instance, the first file might contain k=100M-120M for n=25K-40K, the next k=120M-140M for n=25K-40K, etc. for the rest of n=25K-40K. Then we might do the same with 5 different k-ranges for n=40K-55K, 55K-65K, etc.

This will make these drives much easier to administer. I also think that with the files sorted by k, individuals will find it easier to come up with scripts to stop processing after a k finds a prime and start with the next k. So not only will it save administrative time, it should save CPU time also.

Alas, Sunday has come and gone and I have been left adrift. Maybe Monday says O RLY!! Could be, he became so bored with the deletion effort on NPLB, that he just feel asleep. LOL

Oh, VERY funny he says sarcastically with egg on his face as he bangs his head. :blush::smile:

Yes, I totally forgot to send you the file and you nailed it on the head: I was busy deleting primes posts at NPLB and didn't check any except 1-2 threads at CRUS last night. Look for the file in your Email in the next 10 mins. and I'll show you with the reservation shortly. Sorry about that.

Thanks for the offer to finish things up with this drive! It'll allow us to get the next mini-drive started in the next few days. It can run while you're still working on this one.

To make it official:

Ian is reserving the final range of n=65K-100K for this drive.

Ian, if you can post primes and status every n=5K or 10K as you are progressing with the range, that would help me/Max greatly. I've found it very easy to get way behind quickly here so any time stuff is broken up, it helps.

Thanks again.

This completes this mini drive.

Gary, nice guess on the # k's left in this range. There s/b 75.

Results emailed

Lucky guess on the # of k's remaining.

Very nice work to almost single-handedly annahilate this drive! :smile:
