1. 查看主机型号： dmidecode |grep Product
2. 查看CPU：

查看逻辑cpu个数：grep processor /proc/cpuinfo |wc -l 

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

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

查看cpu是否超线程,如果siblings是cores个数的2倍就是enable了超线程(Hyper-Thread grep "siblings" /proc/cpuinfo | sort

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