cpu speed

Regina Mitchell — Wed, 03 Dec 2003 07:53:23 GMT

How do you find the speed of a cpu if you're not root?

Hi,

normaly I would say,

# echo itick_per_tick/D|adb -k /stand/vmunix /dev/kmem | tail -n1 | awk '{print $2/10000 "MHz"}'

Nut I'm not shure you can do this from a non root user. I do not have a UX system at this moment to try.

HTH,

Shawn,

I use this little script (but it has to be run by root):

HPUX=/stand/vmunix

MHZ=$(echo itick_per_tick/D \
| adb -k $HPUX /dev/kmem \
| tail -1 \
| awk '{print $2/10000}')
echo $MHZ

I don't know of a way to obtain this info as a non-root user.

You could open up a whole can of security worms and put it in a setuid root script ;-) or you could install sudo to run it... (we've been here before haven't we?).

Regards,
John

From the command: # echo "itick_per_usec/D" | adb /stand/vmunix /dev/mem | tail -1

From SAM: Go to Performance Monitors -> System Properties -> Memory

Can use:
# model
9000/800/L1000-36

And just add a 0 (zero) to the last number, so this server has a 360 processor.

Forgot to add, you don't have to be root to do this. I did this as my generic user account.

Model command as a user will give the o/p in this format which has to be understood as speed .

9000/800/N4000-55 ( 550 MHZ)

Hi,

This will give you the processor speed.

echo itick_per_usec/D | adb -k /stand/vmunix /dev/kmem

If you want to run this command as non-root user, you should have read access on /dev/kmem.

Hope this helps.

Or use this script:

Hmm, that picked up some interesting noise.
Change

#include 1$N1
#include :Ã Â
int main(int argc, char *argv[])7!` Ã Â¡

to

And that dropped some characters. :-)
Just remove the odd characters from the
ends of those three lines.
