[[email protected] ~]# lspci | head -10 00:00.0 Host bridge: Intel Corporation Xeon E7 v3/Xeon E5 v3/Core i7 DMI2 (rev 02)00:01.0 PCI bridge: Intel Corporation Xeon E7 v3/Xeon E5 v3/Core i7 PCI Express Root Port 1 (rev 02)00:01.1 PCI bridge: Intel Corporation Xeon E7 v3/Xeon E5 v3/Core i7 PCI Express Root Port 1 (rev 02)00:02.0 PCI bridge: Intel Corporation Xeon E7 v3/Xeon E5 v3/Core i7 PCI Express Root Port 2 (rev 02)00:02.1 PCI bridge: Intel Corporation Xeon E7 v3/Xeon E5 v3/Core i7 PCI Express Root Port 2 (rev 02)00:02.2 PCI bridge: Intel Corporation Xeon E7 v3/Xeon E5 v3/Core i7 PCI Express Root Port 2 (rev 02)00:02.3 PCI bridge: Intel Corporation Xeon E7 v3/Xeon E5 v3/Core i7 PCI Express Root Port 2 (rev 02)00:03.0 PCI bridge: Intel Corporation Xeon E7 v3/Xeon E5 v3/Core i7 PCI Express Root Port 3 (rev 02)00:03.1 PCI bridge: Intel Corporation Xeon E7 v3/Xeon E5 v3/Core i7 PCI Express Root Port 3 (rev 02)00:03.2 PCI bridge: Intel Corporation Xeon E7 v3/Xeon E5 v3/Core i7 PCI Express Root Port 3 (rev 02)
二、檢視CPU資訊
(1)檢視cpu型号
[[email protected] ~]# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c40 Intel(R) Xeon(R) CPU E5-2650 v3 @ 2.30GHz
(2)檢視系統中實際實體CPU的數量(實體)
[[email protected] ~]# grep 'physical id' /proc/cpuinfo | sort | uniq | wc -l2
(3)系統中實際實體CPU的數量(核數)
[[email protected] ~]# cat /proc/cpuinfo |grep 'processor'|wc -l40
(4)檢視每個實體CPU中core的個數(即核數)
[r[email protected] ~]# cat /proc/cpuinfo |grep "cores"|uniqcpu cores :10
(5)檢視CPU的主頻
[[email protected] ~]# cat /proc/cpuinfo |grep MHz|uniqcpu MHz :1200.000cpu MHz :2300.000cpu MHz :1200.000
(6)檢視CPU的詳細資訊

(8)檢視cpu運作模式
[[email protected] ~]# getconf LONG_BIT64
(9)檢視cpu是否支援64bit
[[email protected] ~]# cat /proc/cpuinfo | grep flags | grep 'lm' | wc -l40(結果大于0, 說明支援64bit計算. lm指long mode, 支援lm則是64bit)
