1、使用top命令之后，按下数字1，则显示多个CPU 的信息，和内存信息
[root@testpc ~]# top
top - 15:38:40 up 2 days, 2:05, 2 users, load average: 0.00, 0.00, 0.00

2、查看多核信息
[root@CENTOS ~]# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
16 Intel(R) X CPU @ 1.90GHz
[root@localhost ~]# cat /proc/cpuinfo | grep physical | uniq -c 1 physical id : 0 1 address sizes : 46 bits physical, 48 bits virtual 1 physical id : 0 1 address sizes : 46 bits physical, 48 bits virtual 1 physical id : 0 1 address sizes : 46 bits physical, 48 bits virtual 1 physical id : 0 1 address sizes : 46 bits physical, 48 bits virtual 1 physical id : 0 1 address sizes : 46 bits physical, 48 bits virtual 1 physical id : 0 1 address sizes : 46 bits physical, 48 bits virtual 1 physical id : 0 1 address sizes : 46 bits physical, 48 bits virtual 1 physical id : 0 1 address sizes : 46 bits physical, 48 bits virtual 1 physical id : 0 1 address sizes : 46 bits physical, 48 bits virtual 1 physical id : 0 1 address sizes : 46 bits physical, 48 bits virtual 1 physical id : 0 1 address sizes : 46 bits physical, 48 bits virtual 1 physical id : 0 1 address sizes : 46 bits physical, 48 bits virtual
[root@CENTOS liu]# cat /proc/cpuinfo |grep "processor"|wc -l 16
[root@localhost ~]# cat /proc/cpuinfo |grep "physical id" physical id : 0 physical id : 0 physical id : 0 physical id : 0 physical id : 0 physical id : 0 physical id : 0 physical id : 0 physical id : 0 physical id : 0 physical id : 0 physical id : 0
[root@localhost ~]# cat /proc/cpuinfo |grep "processor" processor : 0 processor : 1 processor : 2 processor : 3 processor : 4 processor : 5 processor : 6 processor : 7 processor : 8 processor : 9 processor : 10 processor : 11

[root@localhost ~]# cat /proc/stat cpu 27115520 242 4622815 4662722506 12504018 246 96658 0 0 cpu0 4126112 0 855568 375445053 10489170 76 32126 0 0 cpu1 2370590 0 291429 389439543 27264 53 6368 0 0 cpu2 1744553 0 225295 390309511 16425 12 3430 0 0 cpu3 1451736 0 256399 390612263 9784 1 3077 0 0 cpu4 911835 0 257589 391264891 7095 0 2000 0 0 cpu5 706379 0 249467 391522706 5312 0 1582 0 0 cpu6 11307712 0 976287 378460372 1915138 0 14559 0 0 cpu7 1069543 0 354557 390922711 9657 0 8219 0 0 cpu8 827844 0 269726 391350780 5797 5 7072 0 0 cpu9 1043103 242 351579 390805163 7193 21 8010 0 0 cpu10 884193 0 298011 391092737 6363 30 6141 0 0 cpu11 671915 0 236902 391496772 4814 45 4067 0 0 intr 3434565703 127 0 0 1 1 0 0 0 1 116 247 0 0 0 0 0 0 0
