使用lscpu：
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit

Core(s) per socket: 2
Socket(s): 1
NUMA node(s): 1
Vendor ID: GenuineIntel

L1i cache: 32K
L2 cache: 256K
L3 cache: 3072K
NUMA node0 CPU(s): 0-3
操作系统将每个硬件线程识别为不同的 CPU。您想要的数字显示在第 行，这与乘以,和CPU(s):相同。Thread(s) per core:Core(s) per socket:Socket(s):
或者您可以使用单个命令：
lscpu -p | grep -c "^[0-9]"
