1. View the CPU model
[Email protected] ~]# Cat/proc/cpuinfo | grep name | Awk-f: ' {print $} ' |uniq Intel (R) Xeon (r) CPU e5-2620 0 @ 2.00GHz
2. View the number of physical CPUs
[Email protected] ~]# Cat/proc/cpuinfo | grep physical |sort |uniqaddress sizes:46 bits physical, bits virtualphysical id:0physical id:1=======>2 a physical CPU3
3. View the number of cores per physical CPU
[Email protected] ~]# Cat/proc/cpuinfo | grep cores |uniqcpu cores:6=======> Each physical CPU is 6 cores
4.CPU whether Hyper-Threading is supported
[Email protected] ~]# Cat/proc/cpuinfo | grep processor |wc-l24=======>24 a logical CPU
[Email protected] ~]# Cat/proc/cpuinfo | grep ' core ID ' |sort |uniq-c 4 core id:0 4 core id:1 4 core Id:2 4 Core Id:3 4 Core ID: 4 4 Core Id:5 The value of the same core ID should theoretically be only 2, and there are 4, which means that hyper-threading technology is used.
