Windows核实NUMA(node)

Socket/Node/Die/Core/Processor的区别

运行msinfo32，看右侧是几个处理器，1个就是单socket，2个就是双socket。

查看CPU个数：

代码语言：powershell复制

(Get-WmiObject -Class Win32_ComputerSystem).NumberOfProcessors

查看vCPU个数：

代码语言：powershell复制

(Get-WmiObject -Class Win32_ComputerSystem).NumberOfLogicalProcessors

除过msinfo32，还有其他命令。

1、https://live.sysinternals.com/coreinfo64.exe

命令用法：coreinfo64.exe -cgnsv

2、https://www.open-mpi.org/software/hwloc/v2.4/

命令用法：hwloc-info

可能有

2个node，双线程（这个我目前还没碰到，碰到了再补图）

2个node，单线程

1个node，双线程

1个node，单线程

举例：

2个node，单线程（注意看每行1个*)

coreinfo64.exe -cgnsv

Get-NetAdapterRss

1个node，双线程（注意看每行2个*)

coreinfo64.exe -cgnsv

Get-NetAdapterRss

1个node，单线程（注意看每行1个*)

coreinfo64.exe -cgnsv

Get-NetAdapterRss

前面说的"2个node，双线程（这个我目前还没碰到，碰到了再补图）"

现在遇到了

像这个就是，80核机器，有2个CPU，每个CPU又是超线程，每个CPU有40个逻辑核

Get-NetAdapterRss

执行coreinfo64.exe -cgnsv的记录如下，

coreinfo64.exe -cgnsv

Coreinfo v3.52 - Dump information on system CPU and memory topology
