在Linux系统中,lscpu命令是用于显示CPU架构信息的工具。通过运行lscpu命令,你可以获得关于CPU的详细信息,包括型号、核心数、线程数、缓存大小等。以下是如何解读lscpu命令输出的一些关键参数:

1. Architecture

2. CPU op-mode(s)

3. Byte Order

4. CPU(s)

5. On-line CPU(s) list

6. Thread(s) per core

7. Core(s) per socket

8. Socket(s)

9. NUMA node(s)

10. Vendor ID

11. CPU family

12. Model

13. Stepping

14. CPU MHz

15. BogoMIPS

16. Virtualization

17. L1d cache

18. L1i cache

19. L2 cache

20. L3 cache

21. NUMA node0 CPU(s)

22. Flags

示例输出解读
