PRIMEOS2 and PRIMEEMX homepage
PRIMEOS2
This is the OS/2 version of the Mersenne prime program by George
Woltman. With it you can participate in the Great Internet Mersenne Prime
Search which is your chance to gain immortality as dicoverer of a
new prime number. See for more information the PRIMEOS2 readme file. The main improvement
over version 2 is the inclusion of the PRIMENET functionality, the larger
FFT's and 64 bit factoring code.
PRIMEEMX
The EMX version of the mersenne prime program is the same as the OS/2
version just compiled and linked in another way so it can work with de
EMX 32 bit DOS extender. It is a bit slower than PRIMEOS2, so OS/2
users should still use PRIMEOS2. See for more information PRIMEEMX readme file. Actually you can use
this on all DOS and Windows platforms but for the most there is not
much to gain. For Windows 95 and NT there is a much better
alternative, Windows 3.1 users might want to use it to be able to test the large exponents. Also there is no PRIMENET functionality available.
Latest version
Since 3 april 1999 version 3.3.1 is available which is a port of the
18.1.2 version of George's program for Linux (mprime). It is still a
beta version. See its README and WHATSNEW files for more information
