Linux View system CPU number, core book, Number of threads

• 
  

Now that the number of CPU cores and threads is getting higher, this article will show you how to determine how many CPUs a server has, a few cores per CPU, and several threads per core.

2. To view the number of physical CPUs
   

   grep ' physical id '/proc/cpuinfo | Sort-u
   

   
   

4. View number of cores
   

   grep ' core ID '/proc/cpuinfo | Sort-u | Wc-l

6. 
   

8. To view the number of threads
   

   grep ' Processor '/proc/cpuinfo | Sort-u | Wc-l

10. 
    

12. instance 1
    

    command execution results, according to the results, this server has 1 cpu,6 cores, each core 2 threads, a total of 12 threads.
    

    through Dmidecode can view the CPU model, according to the model can also find the specific parameters of the CPU

14. Example 2
    

    Command execution results, according to the results, this server has 2 CPUs, each CPU4 core, each core 4 threads, a total of 16 threads.
    

    The CPU model can be viewed by dmidecode and the specific parameters of this CPU can be found according to the model.
