1. Linux  CPU 가상 core를 (Intel Hyperthread) 포함한 전체 Core 수 확인

 

[root@marine1 ~]#
[root@marine1 ~]# cat /proc/cpuinfo | grep process | wc -l
128

[root@marine1 ~]# dmidecode -t processor | grep "Thread Count"
Thread Count: 16
Thread Count: 16
Thread Count: 16
Thread Count: 16
Thread Count: 16
Thread Count: 16
Thread Count: 16
Thread Count: 16
[root@marine1 ~]#

 

 

2. CPU 이하 실제 물리적인 Core 수 확인

 

 [root@marine1 ~]# dmidecode -t processor | grep "Core Count"
 Core Count: 8
 Core Count: 8
 Core Count: 8
 Core Count: 8
 Core Count: 8
