Can you please post the link to the sourceforge-project into the first posting of this thread? (I have found it now in the posting about 1.42 (posting #52) and bookmarked it, but - especially for newcomers - the link seems a bit hidden when it is placed only somewhere in the middle of the thread.)

Now available at sourceforge. This includes a merge of the GPU code into mainline, as well as GPU and non-GPU windows binaries.

Happy factoring,

thanks Jason

Thanks

Now available on the sourceforge page. Major features include a tighter merge of the CPU and GPU poly selection code, the porting of the GPU algorithms into a CPU version (that's pretty slow), and more paranoia with linear algebra checkpoints.

Thank you

Now available on sourceforge. Major changes include support for parallel linear algebra using MPI, and a lot of improvements for NFS polynomial selection. See the changelog on sourceforge for more details.

Happy factoring,

I am sorry to ask this, but is there a windows compiled version of Msieve 1.47?

jasonp · 2010-09-07, 01:00

I'll make an official release of v1.47 in the next few days. A fair number of bugfixes have accumulated since v1.46 was released, which stands to reason because the last release had a lot of new stuff.

Now available on sourceforge. This incorporates a couple of fixes for serious bugs in the NFS linear algebra, and also includes a little tuning for the new Fermi GPU.

Now available on sourceforge.

The major change in this release is a huge overhaul of stage 1 of NFS polynomial selection, courtesy of a great deal of work by jrk with help from me. The code is a great deal better, big CPU serches are actually feasible now, and the GPU code has received an overhaul that should enable higher throughput (no numbers here yet though). Poly selection is fast enough that degree 4 is used for all inputs < 110 digits.

If it was up to me, I'd start an overhaul of stage 2, but maybe I should start on the emergency filtering fixes now, before NFS@Home needs them :)

Happy factoring,
