Try lscpu. Useful lines: CPU(s): 12 On-line CPU(s) list: 0-11 Thread(s) per core: 2 Core(s) per socket: 6 Socket(s): 1 So this machine has one socket, 6 cores in the socket, 2 threads per core, which looks like 12 CPUs. You should find that your has one socket, 4 cores in the socket, 2 threads per core, which looks like 8 CPUs. -dsr-
