Mersenne: another CPU speed benchmark...

I just built up a Pentium-III 450 (128MB PC100 memory running at CAS/3), and I'm testing it at 528MHz with a 115MHz system clock (rock stable so far). Prime95 is benching M=7,636,483 [63 bits] at 0.190 seconds/iteration. My fastest box yet! Is anyone still collecting CPU vs. prime95 speed statis

Mersenne: ECM factoring and P773

A small but valuable group of members of the Mersenne list have been running the elliptic curve method to factor small Mersenne numbers, with some impressive results so far. The outstanding example is Conrad Curry's discovery of the record-holding 53 digit factor of M677, and still the only fact

Two things: 1) I do seem to recall a 1GHz Alpha announcement. 2) Was it Intel that bought the Alpha rights? It might have been IBM but was NOT Compac. Joth - Original Message - From: David L. Nicol <[EMAIL PROTECTED]> To: Aaron Blosser <[EMAIL PROTECTED]> Cc: Mersenne@Base. Com <[EMAI

For a few years. Most PII class MBs have them and some late Socket7 ones do, too. They're not standard as far as how they interface both at the hardware and software levels. You need MB specific drivers. Linux has a project called lm_sensors (named after one of the early chips used to perform

1) see my other email. Yes, they did. 2) Yes, it was Compaq. Intel bought foundry technology that is used on the StrongARM as well as the StrongARM archetecture itself. Cheers, David > -- > From: Joth Tupper[SMTP:[EMAIL PROTECTED]] > Sent: Wednesday, June 09, 1999 1:13

Re: Mersenne: EFF and 10,000,000 digits (fwd)

Intel worked out a licensing agreement with Digital just before Compaq took over. It gave them access to almost all of the technology of the Alpha line, if I recall correctly. I don't think anyone actually bought the Alpha chips; the line stayed with Digital when it went to Compaq. IBM was not
