What is needed before sending to NFS?

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

Completed
7487^61-1 - 900 @ 11e7
7673^61-1 - 940 @ 11e7

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

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.

ECM factored 13789^53-1:

Code:

********** Factor found in step 2: 320302056488442727718936202859814090606710271

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.

RichD · 2015-02-28, 03:19

Completed.
8447^61-1 - 2700 @ 11e7
8543^61-1 - 3310 @ 11e7

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.
