# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c

      8  Intel(R) Xeon(R) CPU            E5410   @ 2.33GHz

(看到有8个逻辑CPU, 也知道了CPU型号)

# cat /proc/cpuinfo | grep physical | uniq -c

      4 physical id      : 0

      4 physical id      : 1 
(说明实际上是两颗4核的CPU)

# getconf LONG_BIT 
   32 
(说明当前CPU运行在32bit模式下, 但不代表CPU不支持64bit)

# cat /proc/cpuinfo | grep flags | grep ' lm ' | wc -l 
   8 
(结果大于0, 说明支持64bit计算. lm指long mode, 支持lm则是64bit)
