1   Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz

[root@xckydb ~]# grep 'physical id' /proc/cpuinfo | sort -u

1

--查看到物理cpu个数为1

[root@xckydb ~]# grep 'core id' /proc/cpuinfo | sort -u | wc -l

6

--查看CPU的核心数为6

[root@xckydb ~]# grep 'processor' /proc/cpuinfo | sort -u | wc -l

12

--查看cpu总线程数为12（6个核心）
