简介
性能测试时一定要确定测试环境和的硬件配置、软件版本配置，那么linux下如何查看服务器的硬件配置信息？以下是本人skylake服务器的配置情况，因为有些命令是必须root用户才可以查看，因此如果有root权限，直接sudo xxx也可
实验环境：skylake服务器 + 3块v100+1块Tesla T4 + pyg/dgl/ogb。
- CPU

查看内存信息
按照单位MB计算的，708930/1024=692.316..感觉不是很一样，可以参考
# free -m
total used free shared buff/cache available
Mem: 708930 14717 684382 403 9830 690423
Swap: 4095 0 4095
查看概要内存使用情况free -g
按照单位GB计算的
# free -g
total used free shared buff/cache available
Mem: 692 14 668 0 9 674
Swap: 3 0 3
自动选择以适合理解的容量单位显示 free -h
和上面的free- g同
# free -h
total used free shared buff/cache available
Mem: 692Gi 14Gi 668Gi 403Mi 9.6Gi 674Gi
Swap: 4.0Gi 0B 4.0Gi
free参数分析参考
- Mem:表示物理内存统计，如果机器剩余内存非常小，一般小于总内存的20%，则判断为系统物理内存不够 Swap: 表示硬盘上交换分区的使用情况，如剩余空间较小，需要留意当前系统内存使用情况及负载，
- 当Swap的used值大于0时，则表示操作系统物理内存不够，已经开始使用硬盘内存了。
第1行数据
- 692G表示物理内存总量；
- 14G表示总计分配给缓存(包含buffers与cache)使用的数量，但其中可能部分缓存并未实际使用；
- 668G表示未被分配的内存；
- shared表示共享内存；
- 9.6G表示系统分配但未被使用的buffers数量；
- 674G表示系统分配但未被使用的available数量

常用的Linux下查看服务器配置的命令
linux下如何查看服务器的硬件配置信息
一、查看cpu信息
1、所有信息 lscpu
2、查看逻辑cpu的数量
3、查看物理cpu的数量
4、查看每个物理cpu的内核数
5、每个物理CPU上逻辑CPU个数
6、判断是否开启了抄超线程：
如果多个逻辑CPU的"physical id"和"core id"均相同，说明开启了超线程
或者换句话说
逻辑CPU个数 > 物理CPU个数 * CPU内核数 开启了超线程
逻辑CPU个数 = 物理CPU个数 * CPU内核数 没有开启超线程
二、查看内存信息
1、free -m
2、查看内存详细信息 cat /proc/meminfo
