CPU information available?

Reggie Chang — Thu, 07 Feb 2002 23:32:10 GMT

Hello,

I wonder if there is a file in HP (10.20 OS)
which keeps the CPU information? (I know that
linux has a file /proc/cpuinfo.)

Or is there a command to find out total number
of CPU? Actually I need to run a system command in a FORTRAN program to detect the total number of CPU. Command top does provide that info. (At least on linux, but somewhat inconvenient. We only have one CPU on our HP machine and the info is not clear.)

All kind of info (except top) is appreciated.

Best regards,

Reggie

Have a look at this thread. It should answer your questions.

Hi Reggie:

I count the number of CPUs this way:

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

Regards!

You don't need to run a system command to get the information in FORTRAN, just use pstat (see the man page). Another way to see hardware is ioscan. For processors:

ioscan -kfC processor

To count them:

ioscan -kfC processor | grep -c processor
