Battlemaxx takes 1280-1285.

1245-1250 complete, no primes.

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.

1260-1265 complete, no primes.
Taking 1295-1300

Kosmaj 2006-05-17 11:58

Battlemaxx also takes 1300-1305.

Correction: 1280-1285 is being processed by John S.

Taking 1310-1315.

Taking 1315-1325 (2 files).

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).

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 ?

[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.
