Good luck levitate!

I would like to reserve 3,333,333 and 3,015,015.

I just found this forum and I would like to search these two k values if they have not been searched and are not currently being tested.

Thanks,
Adam

They are both available AES. Good luck and feel free to PM me if
you need any help.

Ending k = 3,333,333 at n = 400,000

Hey all, I'd like to reserve k = 105105 for 33,219,261 <= n <= 33,554,432. A high weight k with lots of candidates, this should last ... a while.

It sure will, considering the high n value you have. If you're looking for a 10 million digit prime, you'd be better off testing k=3, 5, or 7, as they have a lower FFT size and take about half as much time to test than k=105105 in your 33,219,261 <= n <= 33,554,432 range.

Also, I don't think there's a need to post reservations of k's that have an n value higher than 10M, since RPS won't be getting there for decades (unless all of the GIMPS crunchers switch to RPS today).

Ah, I didn't know that. You really weren't kidding about half as much time either. I ran a few tests and the iteration time for k = 105105 was 100.7 ms, for k = 3 (all other things equal) it was 48.7 ms.

In that case I think I'll work on k = 27, since it's the most dense of the very small ks and the iteration time is only 48.9ms. Plus this project will run as an extension of [url=http://12121.vocabulate.com/]12121[/url]/[url=http://12121.vocabulate.com/27k/]2721[/url] as I am working with Justin.

i show the range n=300k to 550k in the summary. ok!!??

Reserving k=1003 from n=10K. :smile:
