Ubuntu 查看CPU信息

Ubuntu 查看cpu个数及核心数

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CPU型号

cat /proc/cpuinfo | grep 'model name' |uniq
# model name	: Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz

grep "model name" /proc/cpuinfo |awk -F ':' '{print $NF}'
# 输出如下
Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz
Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz
Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz
Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz
Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz
Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz
Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz
Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz

Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz
Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz
Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz
Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz
Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz
Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz
Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz
Intel(R) Core(TM) i9-7900X CPU @ 3.30GHz

查看物理CPU个数

cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l

查看每个物理CPU中core的个数(即核数)

cat /proc/cpuinfo| grep "cpu cores"| uniq

查看逻辑CPU的个数

cat /proc/cpuinfo| grep "processor"| wc -l

查看线程数

grep 'processor' /proc/cpuinfo | sort -u | wc -l

注意，此处查看的线程数是总的线程数，可以理解为逻辑cpu的数量
