Determine number of CPUs on the system

[Weary in West Chester]

Does anyone know is there is a utility that can be used in a script that will list the number of CPUs on the system (optinally with the clock speed) similar to the way "top" lists them out. I tried piping the output from top -d1 into a file, but it gets all jumbled up. Any help would be much appreciated. Thank you in advance.

To find processor speed

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

To find # of processors used

echo runningprocs/D | adb -k /stand/vmunix /dev/mem

Hope this helps,

Hi:

For the number of CPUs (by root or by a non-privileged user):

# sar -M 1 1|awk 'END {print NR-5}'

hi,

You can list the no of processors on the system using ioscan too,

ioscan -fn |grep processor |wc -l

to get the processor speed,

- For HP-UX 9.x:
echo itick_per_usec/D | adb -k /hp-ux /dev/mem,

for 10.x and above
echo itick_per_usec/D | adb -k /stand/vmunix dev/mem

Hope this helps.

Hi

Use the top command and grep what you want !!!

# top 10

I don't know what OS and system you are running - but with Solaris2.6 (there is probably an equivalent for what you are using) I can run the following command to get the speed and number of my CPUs - you may just need to cut what you want from the output:

/usr/platform/sun4u/sbin/prtdiag -v

You guys are the best. Don't ever give up your day jobs or we'll all be screwed. Thanks for all your help.
