剛組裝了一部6核心的電腦 (AMD 1055t+ASUS M4A88TD-V EVO/USB3 500GB HD)，安裝好了CentOS 5後想測試一下系統能否持續運作及温度耗電情形..
1. 安裝 硬體監測程式 lm_sensors
本來以為使用 yum install lm_sensors 就可以了，不過卻發現 lm_sensors 原始網站(http://www.lm-sensors.org/) 己經更新到 3.x版，然而CentOS 5還在 2.x, 更大的問題是kernel版本未把需要的module包進去,
上網找了好久終於找出方法來了，原來在elrepo上有人幫忙維護了CentOS可用的lm_sensors套件：
安裝方法如下:
rpm -Uvh http://elrepo.org/linux/elrepo/el5/i386/RPMS/elrepo-release-0.1-1.el5.elrepo.noarch.rpm
vi /etc/yum.repos.d/elrepo.repo
修改[elrepo]段中的
enabled=1
接著可以安裝 lm_sensors相關套件
yum install lm_sensors*
＊安裝後建議把 sensors-detect 更新
cd /usr/sbin
mv sensors-detect sensors-detect.old
wget http://dl.lm-sensors.org/lm-sensors/files/sensors-detect
chmod u+x sensors-detect
接著就可以執行sensors-detect幫我找出電腦中的sensor
例如：
Driver `it87':
* ISA bus, address 0x290
Chip `ITE IT8721F/IT8758E Super IO Sensors' (confidence: 9)
Driver `k10temp':
* Chip `AMD Family 10h thermal sensors' (confidence: 9)
通常還要下載欠缺相關的module
yum install kmod-it87-PAE kmod-k10temp-PAE
安裝後再執行一次 sensors-detect，便能成功了。
查看資料 執行sensors即可。
[root@localhost sbin]# sensors
k10temp-pci-00c3
Adapter: PCI adapter
CPU1 Temp: +39°C
2. 測試軟體 mprime
mkdir mprime
cd mprime
至http://www.mersenne.org/freesoft.htm下載 mprime for Linux版
wget http://mersenneforum.org/gimps/mprime2511.tar.gz
tar zxvf mprime2511.tar.gz
解開後直接執行
[root@localhost mprime]# ./mprime
Welcome to GIMPS, the hunt for huge prime numbers. You will be asked a
few simple questions and then the program will contact the primenet server
to get some work for your computer. Good luck!
Attention OVERCLOCKERS!! Mprime has gained a reputation as a useful
stress testing tool for people that enjoy pushing their hardware to the
limit. You are more than welcome to use this software for that purpose.
Please select the stress testing choice below to avoid interfering with
the PrimeNet server. Use the Options/Torture Test menu choice for your
stress tests. Also, read the stress.txt file.
If you want to both join GIMPS and run stress tests, then Join GIMPS and
answer the questions. After the server gets some work for you, stop
mprime, then run mprime -m and choose Options/Torture Test.
Join Gimps? (Y=Yes, N=Just stress testing) (Y): N
Number of torture test threads to run (6):
Choose a type of torture test to run.
1 = Small FFTs (maximum FPU stress, data fits in L2 cache, RAM not tested
much).
2 = In-place large FFTs (maximum heat and power consumption, some RAM
tested).
3 = Blend (tests some of everything, lots of RAM tested).
11,12,13 = Allows you to fine tune the above three selections.
Blend is the default. NOTE: if you fail the blend test, but can pass the
small FFT test then your problem is likely bad memory or a bad memory
controller.
Type of torture test to run (3):
Accept the answers above? (Y):

4. CPU温度
利用sensors指令便可查詢目前CPU的温度
[root@localhost sbin]# sensors
k10temp-pci-00c3
Adapter: PCI adapter
CPU1 Temp: +40°C
燒機程式運作了12小時後, CPU的温度大約還是40°C, 看來內建的散熱是足够的.
5。燒機程式運作時消耗電力會從待機的約110 W 昇到 183W左右, 最高有觀察到193 W的數字.
