Hi, please take a short look at this (completed) factorization. Wasn't it too slow (on this fast machine)? Were the parameters correct? Should the matrix be so...
Hi Washuu. 137 hours for a C122 general NFS factorization sounds about right. I have done a C126 in 227 hours and a C121 using the older polyselect in 202...
If your P4 has hyperthreading (don't all the new ones have hyperthreading?), enable it and run a seperate sieving process on each virtual CPU. This should ...
Smart idea! It works here for me. Question: q0 sets the starting point for seiving. Is there a possibilty to set an endpoint to avoid double work?? Bouk. ... ...

Hello everyone, Hi experienced a problem during the sieving part of the GNFS factorization of a c102. Does someone known what is this hind of "Runtime" error ?...

Hello everybody! I have a question. Is it possible to use a second irreducible polynomial with ggnfs? If so, how do I enter it in the *.poly file? Say I wanted...

The good news is that matbuild-tpie has now passed the point at which matbuild crashed. The bad news is that it's taken 2.5 days to get there, while matbuild...
