uniprocessor or multiprocessor

On unix, how could we know whether the system is multiprocessor or uniprocessor?

Solution

  • Some times we have to answer owr own question :)

    On Solaris run the command 

    /usr/sbin/psrinfo -v|grep "Status of processor"|wc -l

    On AIX run the command 

    lsdev -C|grep Process|wc -l

    On HP-UX run the following commands (requires superuser privileges): 

    P=`echo processor_count/D | adb -k /stand/vmunix /dev/mem |tail -1|awk '{print $2}'` echo "The number of processors on `hostname` = $P"

    On Tru64 run the command

     /usr/sbin/psrinfo -v|grep "Status of processor"|wc -l
