1.具有相同core id的cpu是同一个core的超线程。 2.具有相同physical id的cpu是同一颗cpu封装的线程或者cores。 以惠普DL380G6为例说明: ①物理cpu个数: [root@localhost ~]# cat /proc/cpuinfo | grep "physical id" | sort | uniq | wc -l 2 ②每个物理cpu中core的个数(即核数) [root@localhost ...

siblings:单个物理CPU的逻辑CPU数。如果cpu cores数量和siblings数量一致,则没有启用超线程,否则超线程被启用 core id:当前物理核在其所处CPU中的编号,这个编号不一定连续 cpu cores:该逻辑核所处CPU的物理核数。比如此处cpu cores 是4个,那么对应core id 可能是 1、3、4、5 apicid:用来区分不同逻辑核的编号...
