Here's a slightly more efficient version to compute the same thing:
CPU_NUM=`awk '/cores/{print $4 * 2; exit}' /proc/cpuinfo`
However, I'm not sure that will be accurate in all cases.
Try this instead?
CPU_NUM=`awk '/^phys/' /proc/cpuinfo |sort -u | wc -l
Or even:
CPU_NUM=`awk '/^phys/{CPU[$4]++} END {print length(CPU)}' /proc/cpuinfo`
