"PrimeForm" (the former name of this program) allows
probable prime tests of arbitrary expressions, and
deterministic classical tests wherever possible. The
current version, PrimeForm/GW, is available
here for many x86 platforms, including Windows,
Linux, and Mac. It uses the George Woltman libraries
(gwnum), as developed for the GIMPS project, for
high-speed PRP and classical testing of arbitrary forms.
There are both 32-bit and 64-bit builds available. You
will also find a Windows GUI version of PFGW, called
WinPFGW, that can run on Windows XP, Windows Vista, and
Windows 7.
OpenPFGW is an open source project. The
source code is freely available and all contributions
are welcome. You can find discussions on pfgw
capabilities and usage. You can find discussions on
pfgw
releases.
The previous version of the program, "PrimeForm for
Windows", is now obsolete. It is a sister program to Yves
Gallot's proth.exe and uses the same mathematics
libraries as proth.exe. It is still available for users
who prefer a GUI, but it is several times slower than
pfgw.
Many thanks to George Woltman and Yves Gallot for
providing their wonderful mathematics libraries for the
respective program versions. Thanks to Chris Caldwell and
Preda Mihailescu for optimizations of the classical
tests, thanks also go to Chris for supporting the p??
prover codes in the top 5000 database. Above all, thanks
and appreciation go to the numerous mathematicians and
computer scientists whose methods are used by the
program.
