I have removed my the files again.

Do NOT use my compiled binaries, they are not finding any of the known factors. I do not know why.

Default pmfs

In response to Mark’s good questions, I just now sent Luigi a copy of pmfs and requested that he add it to the download page on FermatSearch.org. Included is the pmfs 3.0 Linux binary, example input and output files, documentation and a benchmarking results spreadsheet comparing pmfs to GMP-Fermat. I have started working on a new version in my spare time. So if anyone who uses it has any suggested changes / additions, please post them to this thread and I will try to include them.

Thank you Gary, the news and download pages of FermatSearrch.org have been updated.

I am working on a new updated productivity page as well.

Default Feromant and feromant CUDA

Two new programs, for Windows_64 and CUDA environments have been released on Nov. 29th by Roman Maznichenko. Both look quite promising, both found Fermat factors lately.

I hope I will be able to update the site with the new executables tomorrow, Friday.

I had updated a new performance comparer spreadsheet with GMP-Fermat and pmfs 3.0 timings, tomorrow I will dedicate to Feromant as well and upload the global spreadsheet.

Maybe you could dedicate a stickied thread to performance information such as when you update the page or to address other questions.

I recommend removing proth.exe from the page. Nobody should be using it.

Also on the programs page, the pform link is dead.

I could well dedicate a sticky thread for executables' performance. The fact is that I received GMP-Fermat 2.5, Feromant, Feromant CUDA and pmfs in a couple of weeks, after years of flat calm in the field of Fermat code...

I will remove Proth and the dead links as well, thank you Mark.

I still need a Windows version of GMP-Fermat executable for the site.
Maybe Brian Gladman or Jeff Gilchrist could help here?

Does anyone here have source code to FermFact? I would think that it could benefit from being rewritten as a 64-bit application. If not, then does anyone know the underlying logic for it? In other words, it is using a fixed n sieve or a fixed k sieve or is it doing something completely different?

AFAIK, FermFact is best used to search "squared" ranges of N and k. Version 2.0 also has SSE2 enhancements.
Sadly I could not reach the main developer by email to ask him for the source code

The problem is that I don't know what they mean by "squared".

The number of Ns is close to the number of ks N=80000 to 90000, k=80000 to 90000 is a centered example.
