Lucky you Ryan! Beside of having tons of hardware at your pushbuttons, you are also a lucky son of a gun! I envy you! :smile:
[QUOTE=chalsall;444887][QUOTE=ryanp;444883]And, got it on the first dependency![/QUOTE]
Why does this matter?[/QUOTE]
It saves a lot of time, processing each dependency takes a while, and if you are unlucky and ended up with 50 dependencies or so, which do not give you a factor and you got the factor at the 51st, then you will spend as much time in the square root phase as in the LA phase. I usually end up with ~30 dependencies for my factoring size, and get the factor after 5, or 8, or so.

[QUOTE=LaurV;444935] then you will spend as much time in the square root phase as in the LA phase.[/QUOTE]

A bit exaggerated :shock:...Square root runs under one core if you don't have a script to run it in parallel while the LA uses all cores.

[QUOTE=pinhodecarlos;444937]A bit exaggerated[/QUOTE]
Not at all. Last split I did for aliquot 714192 in this 2-cores laptop, LA in two cores took 15 minutes, and sqrt in single core took 30, with only 4 dependencies hammered. Well, I imagine they do not scale linearly in the 180-190 digits, of course, but thinking of 50 or a hundred dependencies...

No update for a week, seems like Ryan run GNFS on c189@i10740.

We are moving again! :smile:

Dude! Very lucky!

Fifth time could be the charm, finally?

Amazing!!! :fusion::bow::bow::bow::bow::bow::bow::fusion:

:surprised:

If only my sequences caught this many down drivers...

Noooo.. That's impossible! :facepalm: Now I can not anymore wait until Ryan gives up and say "you said it pisses you off and you are going to kill it?"... :sad:

Unreal... amazing work Ryan. Hoping this one goes all the way!

:popcorn:

And it starts again...
