RSALS [B][I]is[/I][/B] the usual suspect. :razz:

I've got 5000 curves, someone else most probably 2000+, so it is ready.

My 1500@43M will be done in about an hour. Edit: akruppa said 2K@44M, so it's definitely ready.

RSALS seldom does GNFS tasks below difficulty 150 :smile:
But RSALS does 27-bit & 28-bit LPs OddPerfect tasks of SNFS difficulty ~200, which are easier than a 28-bit LPs GNFS 147 task.

The near-repdigit 59999_224 (which I chose as a filler because it had received t50) is nearing the required number of WUs, so I'll queue "C147_4788_2967".

In case nobody has started sieving yet, here's a better poly than the one posted earlier:

Just queued 7M-27M (2000 WUs) using this new poly; more than 1500 WUs for 59999_224 will be distributed before WUs for C147_4788_2967.

It will be really fast. I estimated that it would take a week on a quad (similar to e.g. Lucas(1162)) but a week seemed a bit too long. Let's do it in a day - half a day of RSALS sieving and half a day of matrix (I can pick up).

Batalov 2012-04-02 01:24

I ran 700 110e6 curves too. Let's wait till the morning in Europe to see the rsals site up.

Batalov 2012-04-03 05:42

From the first 1Gb of gzipped rels:
Found 13947579 unique, 1461947 duplicate.
Looks ok for tomorrow (when the second 1Gb will be sieved).

Batalov 2012-04-03 18:51

ETA 6 hrs.

Dubslow 2012-04-04 04:51

...so close on the t50.

No particularly small factors on the C148. Ran yafu's factor() up to (not including) B1=1e6, then I stopped it for proper ECM.

Starting 500c @ 43M.

Batalov 2012-04-04 06:12

11e6 is done. I have 800 of 43e6s, and we'll need some more and a poly and the circle spins again.
