Yes, please do! Your work plus mine means half a t55 will be done by tomorrow, so only a t60 (more like 80% of one, if we use 0.31 * digits for ECM depth) needs to be sent to yoyo.
Swellman will let us know when he sends that in, and we'll stop running our t55 once he does. I'm running on half an i75820 (6 cores) and half an HP Z620 (20 cores Ivy Bridge Xeon). I'll keep running t55sized curves (B1=150M, to be specific) after my 0.2*t55 is done, since you're helping, so that we don't have to send any to yoyo.

If no factors are found by either of you then I can then start Yoyo on ECM towards a t60.

Just hit a total of 4500@11e7. If we want to hit full t55, that's something like 20000 curves?
So if we split it in half, it'll take me about twothree more days to hit the 10000. Btw. is there an advantage for 15e7 over 11e7?

As for 15e7 vs 11e7: If I run GMPECM v for one curve at each size, the estimated time to complete a t55 is a bit shorter for 15e7, while the chances of finding a larger factor are better. It's a winwin, but a very small one. It has to do with the default B2 choices GMPECM makes for particular B1 values + memory use for those B2s (in a sense, more memory use for a small speedup). I find a similar result for 6e7 vs 43e6 for a t50, and for 2e7 vs 11e6 for a t45. Basically, I looked for the smallest B1 values above the standard choice for which GMPECM chooses k=2 (and a higher memoryuse + larger B2 choice), and in each case I find the larger B1 choice yields a faster twhatever.

A very interesting experiment! Will definitely try to test this on my HW once we're done with this. Last fiddled with by jagotu on 20191225 at 21:06

Hit a total of 7180@11e7 (managed to free a few more cores so it went a bit faster).
Will try a few curves at 26e7. Last fiddled with by jagotu on 20191226 at 09:34

I ran:
2200@6e7 2000@8e7 3200@15e7 930@30e7 200@42e7 Combined with jagotu's ~7200@11e7, that's a t55 and 14% of a t60. That leaves 75% of a t60 for yoyo, please.

In addition to the 7180@11e7 I ran 2535@26e7, so that should maybe help with the t60 some more (another 6% of t60?).

Nice! So 20% of t60 is done, leaving about 55% for yoyo. I'm using 0.31* digits to get ~59 digits of ECM, which is something like 75% of t60. (my previous post asked for too much of a t60)
Say, 24,000 curves at 26e7 from yoyo?

I’ll queue the job with Yoyo. Two staggered separate rounds of 12,000 curves @B1=260e6.
