I've no idea how residue files interact with the python script, but one file is just fine; the residue is simple text and contains info about the bound, so collecting multiple machine-outputs however you wish will be fine.

I'll still do my 300 at 85e7 and 100 at 29e8, and then as many stage 2 runs as you send me. I can do 40+ a day on my home machine; the rest of my big-memory machines are on campus, less convenient. If you could send a first batch of 100 or 200, I can get started while you generate the rest.

p.s. my email is my forum name at gmail.

I have sent the first set (only 31) to see if I have this right.

Thanks.

Stage 2 running fine. i5 Haswell at 3.1Ghz reports 1280 sec at default B2, 1670 sec when B2 increased 50%. Three curves ran at default B2 = 105e12, the rest are at B2 = 157e12. Peak memory usage reported at 11GB, though Windows' task manager reported 9600MB on this 12GB system.

Is anyone still working on this sequence? How much ECM to date?

VBCurtis · 2016-11-26, 04:32

Ed and I are nearly complete with 3000 curves at 29e8, the last step of the list of curves recommended by the Bayesian-tool. Ed did the 850M curves on his own, and did all the stage 1 for the batch of 3000; I have about 400 stage2's left to finish by Monday or Tuesday.

In other words, it's ready for poly select.

Anybody running poly selection on this? I've no usable GPU, so can't help.

I'm finishing up the range 4M-6M with nothing worth while to mention.

@RichD
Could you please post a couple of good polys for comparison?

RichD · 2016-12-24, 15:44

This is the best of the worst. It seems like I am getting better results in the lower range so I will take 3M-4M next.

Code:

A slightly better one. It appears no one else is working on this so I will take 2M-3M next,
