[QUOTE=gd_barnes;354592]OK, never mind Karsten. I set everything in aliqueit.ini back to the way it was originally and ran it with the -y switch as LaurV suggested.

It worked! 4 threads running ECM now. :smile:

Now, I have another problem. Yafu seems to "hard code" the qs/gnfs crossover at 95 digits. I've found it more effective at 100 digits so that is what I have it set to in aliqueit.ini.

The problem is Yafu over-rides the crossover in aliqueit.ini. So I'm guessing that there is a command that I need to put in yafu.ini to change the crossover. Can someone enlighten me?

Thank you LaurV and Karsten for your help![/QUOTE]

% example NFS/QS crossover for yafu.ini
xover=101.4

Also, I'm not sure if factMsieve will run polynomial selection multi-threaded... does anyone know if it does?

I've kind of skimmed through this, so I might not be on the right track for your difficulty, but to use yafu with aliqueit, you have to have a copy of yafu.ini in the working directory. If you,re running aliqueit from its directory, copy yafu.ini into there and try it.

That did it bsquared. Thanks everyone! I'm all set now. :smile:

And now for my first reservation in ages in the reservations thread of course and with a downdriver too! :surprised

Edit: Wow, with everything except polynomial selection running multi-threaded, this new setup is fast!

Adding to what BB said, use "yafu -tune()", as a separate command, to set the crossover to some optimum value depending on your machine, and delete the xover line (comment it out) in the ini. You will get better performance, as the optimum crossover depends on the machine.

I know factmsieve.py will. There are two variables for # of cores and # of threads. Just make the two of them equal to the number of threads you want running (i.e., 8 cores x 1 threads == 4 cores x 2 threads, as far as I can tell).

Cool, thanks. Is this something the .py script added, or was this capability native to the original .pl? Gary's aliqueit.ini script shows him using the .pl, and he's interested in max threading performance, so just making sure...

[SIZE="1"]edit: Gary you are welcome to use what you like, but just FYI, yafu will do all NFS steps multi-threaded.[/SIZE]

That I don't know. I just changed the .pl line to point to and run the .py version instead (including putting in the python.exe file path) instead, and it seems to work alright, although I haven't done any intensive testing of it.

I am slightly confused as to why your QS/NFS crossover is so high. Are you using windows on this pc? If so are you using the 64-bit asm binaries?

Sounds ok to me, running tune() on my machine with 64 bit binaries, results in:

[CODE]
tune_info= Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz,WIN64,1.02487e-005,0.202433,8.86004,0.0742557,106.648,3393.3
[/CODE]

which, if I am reading it correctly, puts the cross-over at 106.6.
This is running at 4.5GHz not 3.39GHz that Yafu incorrectly detects.

I am surprised that is so high. Maybe I need to check again with a later version of yafu. Once upon a time the optimal value was around 95 with 64-bit everything. Yafu will have improved since then I suppose.
