YAFU version 1.31

bsquared · 2012-04-10, 19:56

Is now available.

Highlights include:
* Several bugfixes
* More assembly optmizations in siqs - a few percent faster across the board (10-20% faster for numbers between about C50 and C65)
* Addition of several requested features (and a few unrequested ones)

Check out the change log for more details.

Enjoy!

Thanks for new version! It seems it has no bug with "crushing" number (I've checked 3 pointed by myself numbers).

Thanks for the new version!

What does "more robust restarting" mean, specifically?

It means I tried to make restarting a previous factorization more foolproof by allowing multiples of an input to still be recognized as the input (using GCD). But, looking closer, I see that I botched it. So it probably won't work any better than what it did previously - and may actually work worse. Let me test it a bit more...

It *was* actually worse. SIQS was unaffected, but resuming NFS was completely broken.

It is fixed now and on SF. This time I've actually verified that both SIQS and NFS will resume if any multiple of the number in the relevant savefile (nfs.job, nfs.dat.p, siqs.dat) is input into yafu.

Please grab the new version if you had previously upgraded to 1.31.

nevermind a modification of the ini did the trick

So I'll wait for the next version and more tests here until I update the yafu@home Boinc server with the new version. We are now running C107/C108. Much thanks on your yafu work.

Probably a good idea.

If, after a couple weeks or so, there haven't been any issues reported, it will probably be ok to upgrade.

Is it safe to stop nfs with the old 1.31 and resume it with the fixed version? Presumably the write/save functions still work?

Yep, that should work fine.

Thanks for the quick fix on the resume feature!

The change of the NSF sieving iteration should save some time. I'm working on a C136 today and I can tell it checks more frequently than it used to. As I went up to C150s I noticed it was over-sieving significantly with the last run.
