Final counts for me.
1500 @ 11e6
5010 @ 43e6
100 @ 11e7

We are getting close. Somebody should start prepping a poly.

I had started a poly search yesterday just in case. Here's my best so far:

Code:

expecting poly E from 1.63e-011 to > 1.87e-011
R0: -8918196985288800478397096030
R1: 452000882238541
A0: -17868270865300818585280188272995245759
A1: 2554206623716922064406317894453
A2: 926232519468248521473303
A3: -56737500114667289
A4: -7429901656
A5: 84
skew 12431740.36, size 9.335e-014, alpha -6.830, combined = 1.587e-011 rroots = 5

I'll go ahead and start the sieving using this one and see how it's looking.

wombatman · 2013-09-27, 15:18

It's looking for a little over 23M relations. I should be able to finish this by tomorrow, barring any issue.

I'm going to be pretty busy through the weekend, so I'm probably not going to have much computer time. Unless you want me to try to provide some sieving, I'll keep my systems pointed at ecm for the 4788 c166.

Thanks...

Nah, I should be able to handle this one pretty easily. Got 4 hyper-threaded cores on my laptop that I'll just let run. At worse, it should take 2 days, but I suspect it'll finish sooner than that. I have the 64-bit lasieve4 binaries, so I got the nice speed increase.

What large-prime bound did factmsieve choose? If it's 29-bit, 23M won't be nearly enough. Also, please comment if the poly performance falls off markedly toward the end- this is one of those extra-high-skew polys that it'd be nice to discover side effects for.

Perhaps post sec/rel at the outset and toward the end, as well as the special-q range it takes to generate the relations you need. It chose 14e, right?

Here's the full file:

Code:

FAMAX 13600000
FRMAX 13600000
SALPMAX 268435456
SRLPMAX 268435456

It looks like it chose 28-bit for the upper bound.

Initial sec/rel are approximately 0.08-0.1, and it did choose 14e.

Edit: Just for extra info, the early yields (for q = 6800000 to 6900000) are ~35,000-37000 per 12,500 q section.

wombatman · 2013-09-28, 19:12

Quick update:

Sec/rel are around 0.07-0.08.
Yield is still about the same as well, if not a bit higher.

Currently at ~33% of estimated minimum relations.

wombatman · 2013-09-29, 18:43

~71% now.

No significant change in yield or sec/rel.
