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

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 :)

1750 more done @ 11e7. We now have:

Code:

900 @ 1e6
3300 @ 11e6
2001 @ 40e6
1601 @ 43e6
   1 @ 1e8
6295 @ 11e7

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:

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 that 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.)
