[Crash893]

I cant believe that there isnt a prime95 thread in there


does anyone else run a team


( see sig for my team)

There must be other guys around here that run this as well. :shrug:

[Crash893]

im sure there are

I have always wondered how "large" prime95 was compared to seti and foldign

not on the forums but in terms of actuall horse power

hmm...i only use prime95 for stability tests on the rare occassions i OC

[Crash893]

$50,000 if you find a 100,000 digit prime

2^(100,000)-1 prime number

[Crash893]

My prime95 stats (http://mersenne.org/cgi-bin/primenet_user.pl?UserID=crash)

[Benvanz]

Doesn't prime95 take like 45k of that money and let you keep 5k? I remember something like this because its "their program"

[Crash893]

actually they take 50k of the 100k reward

25 goes to charity of the creaters wish
2k goes to a bunch of people that found primes up to that point
then the remainder of thier 50k goes back to prime95 to promot inovation

then 50k goes to you

[Crash893]

if you found the 100,000 digit prime you all by your self you could get all 100k from the EFF

If Prime95 moved to BOINC, I'd totally create an account. Primes have always facinated me, and running Prim95 always seemed cool. Perhaps I should just try starting my own project -- Prime06 or something :D

[Crash893]

there has been talk ( bonic is the stat tracker?) joining the stats tracker

the hold up is that there is no diffrence in the stats between teams and individuals in the curent prime95 server
this should be changeing some time soon (primenet v5 is coming out some time this year)

I think seventeen or bust has something to do with primes, and I think prime grid is boinc.

i misspoke

boinic seems like a common platform that allows users to pick what type of work they do

the reason that prime95 has not done this is becuase it was writen in assembly for better use of cpu times

its realy optomized for sse2 (p4s )

man... rackin' up them years, eh?

[Ic3d]

how cna i run two instances ?

[Crash893]

you can ( just have two diffrent .exe's in diffrent folders)

there is however no reall point as prime95 does not leave much unused idle cycles

so running two instances basicly 50% your output but 200% your production

However if you have a dual core or smp you can set the affinity if you have hyper threading treat it like a single cpu as it doesnt give prime any benifit to hyper thread

Can you explain what prime95 does exactly? I always just run it for stability test and never really gave much thought as to what it does. I did a wiki search but really just got that it searches for prime numbers and can test your systems stability.

Most of what you probably need to know is located here

http://mersennewiki.org/index.php/Prime95
there is also a web forum that is suprizingly active ( considering the single focus)
http://www.mersenneforum.org/

basicly the goal is to find mersenne primes and win a cash prize if its over 100,000,000 digits long
the reward is 100,000 that you split up in varous ways but basicly you get some where in the bal park of 50k

man... you got lots of time on your hands, eh? Over 1,100 years of work? That's impressive.

[Crash893]

1100 years of Pentium 90 work

so if i had 1 Pentium 90mhz machine it would take me 1100 years to do all the number checking i have done.


i think that they just use that becuaes that was the standard when they first started in 1995

Yeah I love prime95. But my celery D does hardly anything seeing as though my PC is off at night...
