[QUOTE=bsquared;201391]2500 more curves at 11e7 done.[/QUOTE]

105 more @ 11e7 done on my side. (bsquared, you undoubtedly have got the bigger iron.)

New total:

[CODE] 900 @ 1e6
3300 @ 11e6
2001 @ 40e6
1601 @ 43e6
1 @ 1e8
4543 @ 11e7[/CODE]

This equals to ~1086% of t45 = 200.3% of t50 = 33.6% of t55 = 5.15% of t60

One of the side benefits of my day job, I guess; many fast workstations often left idle on nights and weekends.

1750 more will be done by tomorrow :)

bsquared 2010-01-11 19:54

1750 more done @ 11e7. We now have:

[CODE]900 @ 1e6
3300 @ 11e6
2001 @ 40e6
1601 @ 43e6
1 @ 1e8
6295 @ 11e7[/CODE]

which is ~ 2.5 * t50 or 0.43 * t55

I think this is nearly enough ECM. jrk, how is the poly search going?

It's done. Use this one:

Sieve with 14e from Q=20M to about Q=120M.

[QUOTE=fivemack;201041]Will run 2000@1e8 over the weekend (I have real-work to do on the dual-E5520 machine until then); I think it might now be sensible for jrk to start a polynomial search.[/QUOTE]

Have you done / completed this curves?

fivemack 2010-01-12 17:37

No; I was ill on Friday and didn't get to go into work and start them.

Nonetheless, sieving time now.

Appears that the 4788.2509 c163 has been "set prime'd" in Syd's database.

Batalov 2010-01-16 06:21

You may want to ask Syd to check who did [URL="http://factordb.com/search.php?id=88464188"]that[/URL] and ban the bastard.
This is not the first instance; it had happened to other seqs as well.
(According to Syd's early description, that person must have the "extra permissions".)

Batalov 2010-02-08 03:58

Time to gnfs the c125. (1e6 and 3e6 are done.)


All times are UTC. The time now is 23:08.
