如何找到CPU拓扑？

I am using Intel(R) Core(TM) i5 CPU M 560 @ 2.67GHz as I found out from cat /proc/cpuinfo. But I want to know exact hierarchy like how many sockets are there, and how many cores are there per socket and threads too, if supported. Any idea?

我从cat / proc / cpuinfo中发现我正在使用Intel(R)Core(TM)i5 CPU M 560 @ 2.67GHz。但我想知道确切的层次结构,例如有多少个套接字,以及每个套接字和线程有多少个核心,如果支持的话。任何想法?

5 个解决方案

#1

you can use command

你可以使用命令

lscpu

this will give information

这将提供信息

for processor related info

用于处理器相关信息

dmidecode -t processor

dmidecode -t处理器

#2

lstopo from the hwloc package reports the info you want:

来自hwloc包的lstopo报告您想要的信息:

Socket L#0 + L3 L#0 (6144KB)
  L2 L#0 (256KB) + L1 L#0 (32KB) + Core L#0
    PU L#0 (P#0)
    PU L#1 (P#1)
  L2 L#1 (256KB) + L1 L#1 (32KB) + Core L#1
    PU L#2 (P#2)
    PU L#3 (P#3)
  L2 L#2 (256KB) + L1 L#2 (32KB) + Core L#2
    PU L#4 (P#4)
    PU L#5 (P#5)
  L2 L#3 (256KB) + L1 L#3 (32KB) + Core L#3
    PU L#6 (P#6)
    PU L#7 (P#7)

#3

You can use likwid-topology -g to get cpu hierarchy. This is not available by default in linux, you can install in ubuntu with sudo apt-get install likwid

您可以使用likwid-topology -g来获取cpu层次结构。这在linux中默认不可用,你可以使用sudo apt-get install likwid在ubuntu中安装

#4

You can obtain this info by
lscpu and nproc all other is in /proc/cpuinfo

您可以通过lscpu和nproc获取此信息,其他所有信息都在/ proc / cpuinfo中

#5

You can look at the core id and cpu cores values in /proc/cpuinfo. They should provide the values you need.

您可以查看/ proc / cpuinfo中的核心ID和cpu核心值。他们应该提供您需要的价值。

Alternatively, look at the specifications page of your processor.

或者,查看处理器的规格页面。
