linuxcpu核數查看-ag真人国际官网
ⅰ linux如何查看cpu核心數和內存大小
linux查看cpu核數和內存大罩御高小命令分別為:
1、查看cpu個數*核心數:
cat /proc/cpuinfo |grep「physical id」 | uniq | wc -l
96 #一共96核
2、查看內存總數
#cat /proc/meminfo | grep memtotal
memtotal: 230993600 kb
linux下查看cpu型號,內存大小,硬碟空間的命令:
1、查看cpu核數
cat /proc/cpuinfo | grep 「cpu cores」 | uniq
cpu cores : 12 #12是拆虛單顆cpu的核心數
2、查看cpu型號
cat /proc/cpuinfo | grep 『model name』 |uniq
model name : intel® xeon® cpu e7-4830 v3 @ 2.10ghz
3、查看linux物理內存數量物尺及大小
dmidecode -t memory | grep size: | grep -v 「no mole installed」
