最近有很多用户想在linux系统中查看cpu核数,相信很多用户对于linux这个系统还不太了解,那么linux怎么查看cpu核数呢,接下来,小编就把linux查看cpu核数的方法分享给大家,快来一起看看吧。
linux查看cpu核数:
1.首先我们要知道的是,cpu核数信息一般记录在/proc/cpuinfo中,我们需要通过top进行查询。(linux中的top相当于任务管理器)
2.查看cpu的型号,我们需要在/proc/cpuinfo的后缀上加上”grep name"和"sort“跟”uniq“。
3.输入完成确认后,就开始运行命令。
4.在这里我们要清楚CPU总核数 = 物理CPU个数 * 每颗物理CPU的核数,总逻辑CPU数 = 物理CPU个数 * 每颗物理CPU的核数 * 超线程数。
5.输入以上命令,然后我们可以看见所有physical id都是0,可知有1个物理CPU;也用管道排序去重后直接输出物理cpu的个数。
6.接着我们查看每个物理CPU中的core的个数。(即核数)
7.查看逻辑CPU数目。
8.不想自己算的话,我们也可以直接lscpu。
9.我们可以看见只有1个cpu,2核,支持超线程,所以有4个逻辑CPU。
以上就是linux查看cpu核数的内容,你学会了吗。
