[QUOTE=RichD;396051]Now passing though 800 @ 11e7 - each.
What is needed before sending to NFS?[/QUOTE]

Looking at the previous work I am aware of, the following number of curves at 11e7 will take these to 2/9 of the NFS size.
[CODE]7487^61-1 800
7673^61-1 900
8111^61-1 1600
8447^61-1 2500
[/CODE]

I have one more in the works.
8543^61-1
What would be the curve count @ 11e7 to get it NFS ready?

Dubslow 2015-02-25 17:48

2/9ths of 240 is 53, and the ECM README suggests:
[code]~ ∰∂ tecm 53

Digits B1 B2 num curves brent-suyama curves
50 43e6 2.4e11 8266 7553
55 110e6 7.8e11 20158 17769[/code]

So I guess ~15K curves?

Accounting for the work I'm aware of at 43e6, 3200 @ 11e7 will complete ECM to 2/9 of SNFS size.

Reserving:
13789^53-1

For ECM to T50, then SNFS after I've finished 5443^59-1 and 13513^53-1.

I don't think it's worth fully factoring it, that would be a lot of work for little benefit.

Do you know how much ECM you applied? I try to track these effort levels in case it becomes of more interest at a future date.

Releasing the five p^61-1 numbers to other SNFS resources. These are beyond my capacity.

I ran T40 (about 2300 @ 3e6) and 768 curves at 11e6. The numbers get rounded to a multiple of 256 because my GPU does 256 curves at a time.
