| Hello, Friends,
I get confused how to get cpu speed on alpha /sun/HP/IBM box. Please advise
it. Thanks in advance.
Regards,
Fred

It depends. What OS? Or, you can always open up the box and look,
I suppose. Can you give an example of a system you want to know this
for, as the answer varies by OS?

For modern Sun machines, this info is available via
/usr/platform/sun4u/sbin/prtdiag
With HPUX, you should get that via ioscan for "processor" class.
Dunno about alpha and ibm.

Try /usr/sbin/psrinfo -v. Works for me on Tru64 and Solaris.
I haven't got any IBMs or HPs to test this on so their milage may vary.

| Marcin, and Andy
Thanks for your great help on this.
for HP_UX, I thought command "$model" is enough.

AIX:
lsattr -E -l proc0
(if you haven't got a proc0 device, because you're on a regatta lpar, take
just another procx device)
Linux:
cat /proc/cpuinfo
HP/UX:
echo itick_per_tick/D|adb /stand/vmunix /dev/kmem |\
sed -n 's/.*tick:.\\([0-9]*\\).*/\\1/p'| \
"awk '$1 > 0 {print int($1/10000) \"MHz\"}'
Solaris:
psrinfo -v | grep MHz
Or just use ServDoc (http://servdoc.sourceforge.net) :-)

On HP-UX/Itanium (11i v1.5 and later) the /usr/contrib/bin/machinfo
utility provides detailed processor information. Programatically, you
can determine the processor clock speed using the pstat_getprocessor(2)
syscall.
