Thanks Ernst for spotting the problem! It should be fixed now. It was improper quoting of strings in perl script (single vs. double).

I hate to burst your bubble, but the link in this thread to the project website now says that the page cannot be found.

Thanks Jwb52z!
Hope it works now... I have also made some changes to the stylesheet to improve page rendering in Internet Explorer.

I have uploaded Mfactor_win32_bat.tar.gz  Mfactor automation bat files for win32. They were explained in the guide, but the file wasn't there.

I'd like to reserve M332194169 to 2^68
thanks Foots

The next thing to implement is stats. But how to define a "stats point"? Since I'm going to release exponents to deep search at 65 bits, then the first thing that comes to mind is to define 1 point as factoring from 1 to 65 bits. Formula is:
POINTS = (2^END_BITS  2^START_BITS) / 2^65 Then: 2^1  2^65 = 1 point 2^65  2^66 = 1 point 2^66  2^67 = 2 points 2^67  2^68 = 4 points 2^68  2^69 = 8 points 2^69  2^70 = 16 points 2^70  2^71 = 32 points 2^71  2^72 = 64 points 2^72  2^73 = 128 points 2^73  2^74 = 256 points 2^74  2^75 = 512 points But I see one problem  it is currently minor, but unacceptable in the long run. The larger the exponent is, less factors per bit are tested and thus stats become unfair. For example, testing 332,192,831 from 65 to 66 bits takes 10 times as long as 3,321,928,319 from 65 to 66 bits. Are there other possible "stats points"?

Thanks cheesehead for the idea!
So, the formula becomes: where EXPMIN=332192831 Last fiddled with by gribozavr on 20060211 at 18:00

Gribozavr, that's an extremely small number if my calculations are correct using your example. It's just a little bit over 9x10^12.

Yes, that is a small number now, but it will grow as the project advances and we start factoring larger exponents. But how much time will pass until then?..
On the other hand, AMD64 and Mfactor can bump the project very much. I have an Athlon64 3000+ 1.8GHz w/ 512Kb cache and spend 95% of its CPU time on 100mdpp. There are many people now with much fatser Athlon64's and even dualcores. Mfactor on AMD64 running under 64bit Linux is the fastest configuration now. So, if anyone has such configuration, you are welcome to join us! Last fiddled with by gribozavr on 20060212 at 11:49
