查看cpu相关信息
在linux系统中，提供了/proc目录下文件，显示系统的软硬件信息。如果想了解系统中CPU的提供商和相关配置信息，则可以查/proc/cpuinfo。
但是此文件输出项较多，不易理解。例如我们想获取，有多少颗物理CPU，每个物理cpu核心数，以及超线程是否开启等信息，下面我们就看来一步一步的去探索。
基础概念
①物理CPU数（physical id）：主板上实际插入的cpu数量，可以数不重复的 physical id 有几个
②CPU核心数（cpu cores）：单块CPU上面能处理数据的芯片组的数量，如双核、四核等
③逻辑CPU数：一般情况下，
逻辑CPU=物理CPU个数×每颗核数 #不支持超线程技术或没有开启次技术
逻辑CPU=物理CPU个数×每颗核数 *2 #表示服务器的CPU支持超线程技术（简单来说，它可使处理器中的1 颗内核如2 颗内核那样在操作系统中发挥作用。这样一来，操作系统可使用的执行资源扩大了一倍，大幅提高了系统的整体性能）
实际解读
话不多少，看图说话。下图是我负责维护的一台服务器的CPU信息。使用cat /proc/cpuinfo。

下面对上图的输出内容进行相应解释
processor ：系统中逻辑处理核心数的编号，从0开始排序。
vendor_id ：CPU制造商
cpu family ：CPU产品系列代号
model ：CPU属于其系列中的哪一代的代号
model name：CPU属于的名字及其编号、标称主频
stepping ：CPU属于制作更新版本
cpu MHz ：CPU的实际使用主频
cache size ：CPU二级缓存大小
physical id ：单个物理CPU的标号
siblings ：单个物理CPU的逻辑CPU数。siblings=cpu cores*2 。
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，系统中每个逻辑核的此编号必然不同，此编号不一定连续
fpu ：是否具有浮点运算单元（Floating Point Unit）
fpu_exception ：是否支持浮点计算异常
cpuid level ：执行cpuid指令前，eax寄存器中的值，根据不同的值cpuid指令会返回不同的内容
wp ：表明当前CPU是否在内核态支持对用户空间的写保护（Write Protection）
flags ：当前CPU支持的功能
bogomips：在系统内核启动时粗略测算的CPU速度（Million Instructions Per Second
clflush size ：每次刷新缓存的大小单位
cache_alignment ：缓存地址对齐单位
address sizes ：可访问地址空间位数
power management ：对能源管理的支持
快速查询想要获取的信息
- 查询系统有几颗物理CPU：cat /proc/cpuinfo | grep "physical id" |sort |uniq
[root@localhost ~]# cat /proc/cpuinfo | grep "physical id" |sort |uniq
physical id : 0
- 查询系统每颗物理CPU的核心数：cat /proc/cpuinfo | grep "cpu cores" | uniq
[root@localhost ~]# cat /proc/cpuinfo | grep "cpu cores" | uniq
cpu cores : 10
- 查询系统的每颗物理CPU核心是否启用超线程技术。如果启用此技术那么，每个物理核心又可分为两个逻辑处理器。
[root@localhost ~]# cat /proc/cpuinfo | grep -e "cpu cores" -e "siblings" | sort | uniq
cpu cores : 10
siblings : 20
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。
- 查询系统具有多少个逻辑CPU：cat /proc/cpuinfo | grep "processor" | wc -l
[root@localhost ~]# cat /proc/cpuinfo |grep "processor"|wc -l
