Linux基礎常用營運操作 cpu

1. 查看主機型號： dmidecode |grep Product
2. 查看CPU：

查看邏輯cpu個數：grep processor /proc/cpuinfo |wc -l 

查看物理cpu個數： grep "physical id" /proc/cpuinfo | sort|uniq|wc -l

查看物理croe數grep "cpu cores" /proc/cpuinfo | sort|uniq grep "core id" /proc/cpuinfo

查看cpu是否超執行緒,如果siblings是cores個數的2倍就是enable了超執行緒(Hyper-Thread grep "siblings" /proc/cpuinfo | sort

查看cpu型號 cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c dmesg |grep -i xeon
