查看物理CPU个数
(venv2) LIST_2080Ti@ubuntu-SYS-7049GP-TRT:~$ cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l
2
查看每个物理CPU的核数
(venv2) LIST_2080Ti@ubuntu-SYS-7049GP-TRT:~$ cat /proc/cpuinfo| grep "cpu cores"| uniq
cpu cores : 12
查看逻辑CPU个数（线程）
(venv2) LIST_2080Ti@ubuntu-SYS-7049GP-TRT:~$ cat /proc/cpuinfo| grep "processor"| wc -l
48
查看具体CPU数
(venv2) LIST_2080Ti@ubuntu-SYS-7049GP-TRT:~$ cat /proc/cpuinfo| grep "physical id"| sort| uniq
physical id : 0
