리눅스 하이퍼스레딩 확인

1 방법 1: cpuinfo

[root@jmnote ~]# cat /proc/cpuinfo | grep 'cpu cores' | head -1
cpu cores	: 4
[root@jmnote ~]# cat /proc/cpuinfo | grep 'siblings' | head -1
siblings	: 8

2 방법 2: dmidecode

[root@jmnote ~]# dmidecode -t processor | grep 'Core Count' | head -1
	Core Count: 4
[root@jmnote ~]# dmidecode -t processor | grep 'Thread Count' | head -1
	Thread Count: 8

dmidecode -t processor | grep HTT

실행예시 (활성화됨)

[root@jmnote ~]# dmidecode -t processor | grep HTT | head -1
		HTT (Hyper-threading technology)

실행예시 (비활성화됨)

[root@jmnote2 ~]# dmidecode -t processor | grep HTT | head -1
