yafu memory usage for ecm

My 16GB RAM machine started to swap while performing ECM.

I see that GMP-ECM has parameter to limit memory usage for stage 2


Is there a similar option available for yafu?

If I press control+c, the ecm processes are killed, but yafu continues by spawning next threads using next curves.
If I send...

Thanks guys!

What about 1024 bit random integer? (a=200/1024)?

Dickmen's function seems to be something too hard to grasp for me.

factoring special form of 1024-bit RSA key

Hi,

I have 1024-bit modulus I want to factor. It has a special form.
I know that one factor is 512-bit random prime, but another factor is random non-prime 512-bit number (thus it has unknown...
