The 3rd RPS Drive: low-weight Ks for megabit prime
 
Due to the recent interest in low-weight Ks, Thomas has donated
his sieved files for 36 K values starting at n=1.1M. This drive will
take them to n=2M. Any primes found at the current level of
n=1.6M should come in around the top-50!

List of 36 Ks being tested:

[/CODE]

Completion times: on the average 2.4 GHz P4 these should take
about 7 days or so to complete (9500 sec per number @ n=1.57M).

Please send results from this drive to Thomas at [EMAIL="rps_3rd_drive@yahoo.com"]this address[/EMAIL]. Thanks.

Happy hunting!

1225to1230 and 1235to1240 updated with latest sieving results, one candidate less in each. But actually Thomas kind of disappeared :wink: and until he comes back with the latest input file with all sieving candidates removed I think we better wait, to avoid processing numbers already sieved-out.

I reestablished connection with Thomas and got the latest input file, but I'm releasing only 4 files because in about 24-30 hrs from now Thomas is going to fill all gaps to p=3T and we'll have a few more sieving ranges completed.

We stopped sieving at 4238bn. Please note that files in the 1295-1330 range (except 1305-1310) still have the old sieve limit of 3750bn, that's because no new factors were found after extra sieving.

BTW.: We are down to less than 9000 remaining candidates! :showoff:

The next FFT length change occurs at n=1326659 (SSE2 machines) or n=1351659 (non-SSE2 machines). Therefore the ranges 1325-1350 would be best suited for non-SSE2 machines (e.g. PIII or Athlon).

Kosmaj 2006-05-18 09:17

Thomas, thanks for the info. I have no Athlons doing LLR but I marked 1325-1350 for people who have them. Gentlemen, declare your Athlons! :lol: If there are none I'll remove the Athlon section.

BTW, how about Opterons and Athlon-64's ?

Thomas11 2006-05-18 09:40

[QUOTE=Kosmaj]BTW, how about Opterons and Athlon-64's ?[/QUOTE]

In LLR 3.6 (or perhaps 3.5) the SSE2 code got a significant speed-up on Opterons and Athlon64's (significantly more than on the P4 machines!).
Therefore it is now faster to run them in SSE2 mode at the larger FFT length than running in non-SSE2 mode at the smaller FFT length.
