Mersenne: Meganet Corp.

1999-11-02 Thread Glenn Maitz
Dear everyone, I may have missed this, but was there any final judgment on the Meganet Corp. claim that they had a "deterministic and polynomial-time" prime test? There were some discussions on the list early this year when they first made their claim. But I don't recall reading about any resol

The behavior of the recursion x[n+1] = x[n]^2 - 2 can be precisely analyzed. (In fact, it is because of this that the LL-test works at all.) For a fixed prime p, the periodicity depends on the factorization of either p-1 (if x[1]^2-4 is a quadratic residue mod p) or p+1 (if x[1]^2-4 is a quadratic

Mersenne: Mlucas on SPARC

1999-11-02 Thread Bill Rea
Gimpsters, If there are people with SPARC systems with large external caches thinking about using Ernst Mayer's Mlucas for LL testing then make the switch. I will be switching from MacLucasUNIX on an E450 with 400Mhz CPU with 4Mb caches to Mlucas as soon as the current exponents finish. I ran a f
