    1818 * [http://virtualization.sys-con.com/node/839464/print Virtualization for High Performance Computing]
     19
     20== Green Computing ==
     21
     22 * 在 Debian 跟 Ubuntu 都有一個套件叫做 [http://packages.debian.org/etch/lm-sensors lm-sensor] - utilities to read temperature/voltage/fan sensors
     23{{{
     24~$ sudo apt-get install lm-sensors
     25~$ sudo /etc/init.d/lm-sensors start
     26~$ sudo sensors-detect
     27
     28這個指令會跑很多測試，我跑出來最後秀這行，我就把它加到 /etc/modules
     29To load everything that is needed, add this to /etc/modules:
     30
     31#----cut here----
     32# Chip drivers
     33coretemp
     34#----cut here----
     35
     36~$ sudo modprobe coretemp
     37~$ sudo sensors
     38coretemp-isa-0000
     39Adapter: ISA adapter
     40Core 0: +40.0°C (crit = +100.0°C)
     41
     42coretemp-isa-0001
     43Adapter: ISA adapter
     44Core 1: +37.0°C (crit = +100.0°C)
     45}}}
     46 * 透過 lm-sensors 可以知道現在 CPU 溫度是多少。還有另外一個跟 lm-sensor 有關的套件叫 [http://packages.debian.org/etch/sensord sensord]，應該就可以幫忙紀錄歷史 CPU 溫度吧~想操機器的可以試試看 CPU 一直維持 99% 時，溫度是怎麼變化 :)
