% lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 2 On-line CPU(s) list: 0,1 Thread(s) per core: 1 Core(s) per socket: 2 Socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 23 Stepping: 10 CPU MHz: 2401.000 BogoMIPS: 4788.03 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 3072K NUMA node0 CPU(s): 0,1
