We need to queue more work in all applications up to:

14e - 300k wu's
15e - 300k wu's
16e - 2.0M wu's

People are already bunkering for the 16e application.

Damn, this is fucking serious, we need more 14e, 15e and 16e wus.

Are you prepared to accept GCW S250-251 numbers with <t55 ECM pre-testing? If so, I can find several for the 14e queue. Likewise for c166-c170 for GNFS.

Otherwise, between us NFS@Hme and I have cleaned out 14e targets. 15e targets have not yet had anywhere near t55-t60 despite the efforts of yoyo@home and the ECMNet contributors.

IOW, what is acceptable in "emergency" cases like this?

I can deal with that. Can you please send a poly file from all those SNFS composites to Tom as he is been adding work to the 14e queue. We also have more than +40 composites ready from Homogeneous Cunningham.

The following snippet is from a script I use to evaluate whether candidates are ready for SNFS. The original contains the full decimal expansions but they've been abbreviated here for clarity, at the cost of losing the digit counts. They are 227, 166 and 210 digits respectively.

Code:
139428208400	794...739	GW_9_260	250.518025802195
382335208400	Done to B1= 43000000 (t50)
1343845208400	140...763	GC_4_411	250.060498257668
2349575208400	Done to B1= 110000000 (t55)
3097075208400	222...759	GC_6_319	250.734039555439
13284395208400	Done to B1= 260000000 (t60)
The first column is a measure of ECM work done, the 2nd (in general) is the decimal expansion and the 3rd the symbolic name. The final column is the SNFS difficulty. Interspersed at the correct points are the levels at which a full 5-digit ECM level has been completed. These three are those which are less than S251 and which have at least a third of a t50 completed. It's quite likely that more, as yet unreported, ECM effort has been performed by Sam Wagstaff.

The attached file contains SNFS polynomials for these numbers. Note that it is marginal whether GNFS or SNFS is better for a C166/S250. I don't yet have a GNFS polynomial. Anyone wanting to find one and perform trial sieving is welcome to do so.

Note that there could quite easily be a p4x ECM miss in any of these candidates. If you're prepared to take the risk, go ahead.


I'll reserve these 3 on the web page and tip off SSW as well. He's working his way through the S25x numbers but hasn't yet done any S250.

There is no need for more candidates. Only a need for someone to put the existing candidates in the queue. There are 61 homogeneous Cunninghams ready for SNFS and polynomials for all of them--complete with parameter selection--have already been posted previously.

Good.

That is not what I understood from Carlos' posting.
