Mersenne: Security and Prime95/mprime

2000-03-02 Thread St. Dee
Hi, I'll likely be moving to a cable modem soon and intend to install a machine to act as a firewall, likely a Linux box. Since it will be sitting there all day doing nothing other than screening stuff between my LAN and the 'Net, I thought I'd run mprime (if Linux) on it. Of course, all of

Mersenne: Curious Prime95 behavior?

2000-02-13 Thread St. Dee
Hi, I'm running Prime95 on a machine with a PII-400 doing LL tests. The machine finished up an exponent in the 9,000,000 range (512K) and started doing an LL test on an exponent around 828. I expected the iteration times to speed up (384K or 448K, not sure which for the lower exponent),

Mersenne: Mprime in dual cpu setup?

1999-10-14 Thread St. Dee
Hi, I'm running mprime (v19) on a dual-processor box (RH 6.0, very basic, no graphical interface at installed) and am curious about the hit others take when moving from using one to two processors. (People running duals under NT are also welcomed to respond!) If I run a single instance of

Mersenne: mprime V19--correct behavior or glitch?

1999-09-27 Thread St. Dee
Hi, I just updated several Linux machines to mprime V19. I have all of my machines set to get 45 days worth of work. Two of the machines, which were nearly down to having only 45 days worth of work remaining, immediately contacted PrimeNet, got an additional exponent each, and factored that

Does anyone else notice that their Celeron based machines seem to take a relatively bigger performance hit when moving from testing exponents in the 384K FFT size to the 448K FFT size (under V18.1, at least)? I have a couple of non-overclocked Celeron 400 machines and, at the 384K FFT size, they
