Yoyo is finishing up 48,000 curves @B1=850e6. I consider ECM complete.

Since this is a record score, I'll guess we can think about sieving it or sending it to NFS@home?

swellman 2021-10-04 20:47

Small world - I was just reviewing this thread and realized the same thing.

The f_small siever can handle a job of this size.

swellman 2022-01-02 23:22

NFS@Home sieved this and Greg ran the LA.

I advanced it up to i1695 (c185) but now it’s free to anyone that wants it. Good luck!

Hey, that's only because it's Jan 5 :smile:

ryanp 2022-01-09 00:57

Handing off this sequence for now at i1704, which has a c175.

bur 2022-01-20 17:25

Just for the record, there was probably a lot of ECM work done already?

ryanp 2022-01-20 19:54

[QUOTE=bur;598416]Just for the record, there was probably a lot of ECM work done already?[/QUOTE]

On the c175 at i1704, I did 19K curves at B1=26e7.
