Question No ECM factoring assignments found.

One of my workers is set to get ECM Fermat work. I lately I have been getting TF assignements instead:

PrimeNet success code with additional info:
No ECM factoring assignments found.
Server assigned trial factoring work.


Is this a site-wide phenomenon or could something happen to my computer (maybe low rolling average) that makes it not good enogh for ECM Fermat work?

Plenty of memory assigned -- so that is not it...

Thank you

Check that you have WorkPreference=6 in prime.txt under the specific worker thread.

Otherwise you can add the lines manually. Be careful that F27-29 requires a lot of RAM. I tried F29 once and I think it used >3 Gb in stage1 alone, never finished it.

The 2nd 1 is the number of curves to run which you can increase of course.

Code:

That would be the 3rd "1".

Right, I can't count. The one before the " or at the end of the line for F20+F24:

F12:ECM2=1,2,4096,1,260000000,26000000000,1,"114689,26017793,63766529,190274191361,1256132134125569,568630647535356955169033410940867804839360742060818433"

F20:ECM2=1,2,1048576,1,11000000,1100000000,1

The ECM choice lets you factor numbers of the form k*b^n+c.......

Question

I tried doing curves with higher bounds; the PrimeNet sever accepted results and gave me credit, but the results did not show up on the ECM Progress report.

I guess we are supposed to complete a certain number of lower bound curves before moving up to higher bounds. Is that right?

I took B1 values from the ECM Progress report table header, and for B2 I was simply multiplying B1 by 100.

They were "converted" into a larger number of curves at smaller bounds.
