To my knowledge, RSA896 is not currently sieving.

In order for Msieve poly selection to be practical for RSA1024, even with a large number of GPUs, the code will need some changes to handle the...

The GPU code running on a hot card is about 5x faster than one core of a hot PC, so the situation here is not remotely equivalent to trial factoring.

I'll repeat that RSA896 is a better idea to...

Dubslow, it's a little early to want a schedule from me; I have a day job for that. Suffice it to say that the current code is utterly inadequate (as in by a factor of 100) for any postprocessing...

To correct a previous post about CADO-NFS, the code was mostly written by full-time faculty, plus contributions from their students. Paul reports that they do accept outside contributions as long as...

The best way to split poly selection is to have one group of computers run stage 1 plus the size optimization part of stage 2, which is a lot slower for degree 6 but still pretty quick in absolute...

Ben has wanted to build a lattice sieve but has been extremely busy (plus I suspect a kilobit-ready lattice sieve is not the best beginner project). I've been working on GMP-ECM and have also been...
