Interesting, i'll have to give my atom netbook a shot.
In the mean time, my [email protected] with ddr2-1200-5-5-5-15 ram:

I hope i ran this correctly I ran : sh super_pi 20 & sh super_pi 20 & sh super_pi 20 & sh super_pi 20 & sh super_pi 20 & sh super_pi & 20 sh super_pi 20 & sh super_pi 20

Code:

generalmac@monster:~$ cd ~/super_pi

& sh super_pi 20 & sh super_pi & 20 sh super_pi 20 & sh super_pi 20

Yup, that'll load up all four logical cores, you can do it with a single one as well if you want to compare that score with the rest of us and see how single-core speed goes.
You can use 25 instead of 20 for a stability test, it lasts quite a bit longer (calculating 32 million numbers instead of 1 million) so from a stability point of view it's better, but it takes an awfully long time to use as a comparison type benchmark (hours on an atom for instance!)

Your post makes me want an i7.

is this a deceint score..and it must be stable right?

Bobnova · Aug 31, 2009

Certainly stable as far as superpi is concerned. FAH should be stable as well, it's a rare OC that is superpi stable and not fah stable, usually it's the other way around.

GeneralMac · Sep 1, 2009

lol well it was a rare thing then..started fah and gpu2 folding @4.3 and shut down..lol
im thinking it might be my psu, if ya can call it that..mach1 1000 watts of crap

Bobnova · Sep 1, 2009

A straight up shutdown sounds much more PSU-ish. I've had three different oddball folding issues due to what looked like a stable OC lately. One i lost video on completely, but the box still had power, just wasn't doing anything.
The next FAH just stopped. Didn't error, didn't close, it just stopped calculating.
And the third was a random reboot that i missed, but blame FAH and the overclock for

Might be worthwhile to run just CPU fah for a day to see if it's OC based or PSU based.

Shameless bump, cause it ain't stickied.

Bobnova · Nov 20, 2009

Another bump for one of the few linux benchmarks.

Neuromancer · Nov 20, 2009

Looks like it is faster because of some differnce in Data output speed. Seems to be almost no differnce in total time and time of the initialization plus 19 loops

Where as in windows the last step is about the same as the difference between any of the loops.

graysky · Nov 21, 2009

Anyone have the source code for superpi? I'd give this a shot if I can compile it myself. I'm using an x86_64 Linux though.

I.M.O.G. · Nov 22, 2009

If members of the benchmarking team think this should be stickied, just let me know and it will be done.

hello,
I've got a problem with the command "sh super_pi 20"
he tells me "1: ./pi not found".

same... whats the fix for this??

Make sure you're in the directory containing super_pi, then try "./super_pi 20"

Tried all that and no go..

Bobnova · Dec 9, 2009

Try putting super_pi and pi into your home directory and running 'em there.
If that doesn't work, i have no idea what might be wrong.

SuperMiguel · Dec 10, 2009

nup not working :s weird

Bobnova · Dec 10, 2009

Huh.
Try re-downloading it maybe?
I'm stumped.

SuperMiguel · Dec 10, 2009

tried and no go.. not sure whats going on.. ima copy both files to my /sbin folder and see if it runs from there when i get home
