You may use: #cat /proc/cpuinfo | grep "physical id" | sort | uniq | wc -l To get the number of CPU "slots" you have on the machine. And then: #cat /proc/cpuinfo | grep "cpu cores" | uniq To get the number of cores per "slot". Then you just have to multiply both numbers and you know how many "real cpus" you have on the system. Otherwise you may be counting virtual processors, which shouldn't be used for heavy stuff such as compiling. Regards, Vitor
