Mersenne: Re: Is 128 bit instruction code needed ?

1998-10-29 Thread Bojan Antonovic
So far, the drive towards more bits in the instruction code is by the need to address more data rather than the needs to compute longer integer or higher numeric precision. And this is usually driven by 2 factors : The computer RAM size and the biggest Database size required commercially .

Mersenne: Primenet software under Win95 and OS/2

1998-10-29 Thread Richard G. Larson
I've been running Mersenne computations on various machines for a longish time. This summer I switched from the manual method to the Primenet server. All under OS/2. I'm currently using: Thu 10-29-1998 13:32 [D:\MERSENNE]primeos2 -v Mersenne Prime Test Program, Version 16.3.2 OS/2 - EMX
