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
    • 型号：Intel® Xeon® Gold 5118 CPU
    • 内存：692G
    • 内核：48核
  • GPU
    • V100 *3
      • 显存：32G
    • Tesla T4 *1
      • 显存：16G

内存

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

  1. # free -m
  2.               total        used        free      shared  buff/cache   available
  3. Mem:         708930       14717      684382         403        9830      690423
  4. Swap:          4095           0        4095

查看概要内存使用情况free -g

按照单位GB计算的

  1. # free -g
  2.               total        used        free      shared  buff/cache   available
  3. Mem:            692          14         668           0           9         674
  4. Swap:             3           0           3
  5.

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

  1. # free -h
  2.               total        used        free      shared  buff/cache   available
  3. Mem:          692Gi        14Gi       668Gi       403Mi       9.6Gi       674Gi
  4. 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

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
