The K6 (as well as Cyrix and Intel 486) chips have lousy floating point units. So bad in fact that a 400 MHZ K6 is about 3 times slower than a 400 MHz PII when it comes to LL testing, ECM, and P-1 factoring. What you need is a project that uses integer arithmetic - like distributed.net. The only GIMPS project that is mostly integer is factoring to a low limit. At some point (I think factoring above 2^62) prime95 switches from an integer algorithm to a floating point algorithm. What you can do, if you don't mind operating manually, is to grab a block of exponents above 20,000,000 (either by email or from the downloadable files at http://www.mersenne.org/status.htm) and factor them to 2^62. There is a factoring limit override switch described in undoc.txt. Do not use this switch with Primenet. Email your factoring results when you are done. _________________________________________________________________________ Unsubscribe & list info -- http://www.ndatech.com/mersenne/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
