SNFS targets which need more ECM - Page 2

Andrey: why isn't the work defined by the top post on this list being queued up on yoyo@home?

Completing 7610@43M on numbers which are 300-digit SNFS difficulty and unlikely to be sieved this decade is not obviously a higher priority than getting tractable numbers ready for processing. Running the appropriate ECM on a single individual's resources is going to take a lot longer than sieving the number on nfs@home resources.

There are few t50 tasks remaining. Meanwhile I feed yoyo@home with some heavier tasks to get ready GNFS targets (currently there are two C178's and four C181's, fitting 15e I hope). I'll take into account SNFS/GNFS difficulty to build a t55 queue for yoyo@home.

ECM completed with no factors found. I'll request it for NFS@Home sieving in 14e queue, along with a few other stragglers.

Can we add the following to the table? Please note I am not reserving any of them, just noting them for preprocessing prior to queuing with NFS@Home.

C208_148_104 7k curves @11e7
C178_140_114 full t55
C194_137_54 6k curves @11e7

All have (or will shortly have) completed t50.

Fivemack's new ECM toy may change the above values, or perhaps the entire table.

May I also request the following be added to the table, each for 8000 curves @B1=11e7

C212_138_53
C226_137_55
C216_131_67

Thanks.

I've got some business travel coming up, so it is my intent to concentrate on performing ECM for the foreseeable future. ECM on things like this table...

swellman · 2016-07-15, 13:53

Can we add the following to the table, with a target of 9000 curves each at B1=11e7?

C211_121_95
C229_123_88
C227_124_85
C201_125_82
C234_138_82

These are the last of my nominees for this thread until a lot of the backlog is chewed up. Thanks.

Reserving C254_125_111 (initially running 4992@3e8)

There will be quite a lot of changes. For the C208 which is a S238 according to yafu it recommends [[1, 300], [3, 800], [11, 200], [43, 2700]] which is a lot less.

I've always felt the traditional rules of thumb required a LOT of ECM. If Baysian analysis tells us to reduce it (with props to RDS et al), I'm all for it.

Reserving C178_140_114 for ECM to t55. Thank you.

XYYXF · 2016-08-03, 10:16

I'll probably enqueue all t55 tasks to yoyo in September.
