CPU

总核数 = 物理CPU个数 X 每颗物理CPU的核数

总逻辑CPU数 = 物理CPU个数 X 每颗物理CPU的核数 X 超线程数

  • 查看路数/Socket(s)
cat /proc/cpuinfo | grep -i "physical id" | sort | uniq | wc -l
  • 查看每路核心数
cat /proc/cpuinfo | grep -i "cores" | uniq
  • 查看是否开启超线程
cat /proc/cpuinfo | grep -i "siblings" | uniq

如果cpu cores数量和siblings数量一致,则没有启用超线程,否则超线程被启用
