查看CPU信息(型号)?
# 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)?
