Install prerequisite packages
Install the following packages:
[Jon@TestNode powerbench]$ yum install compat-gcc-34-g77 lapack lapack-develDownload Powerbench
The Powerbench files can be obtained from:
http://it-div-procurements.web.cern.ch/it-div-procurements/Download/powerbench.tar.gz.
Download and extract the Powerbench software on the test system:
[Jon@TestNode powerbench]$ wget http://it-div-procurements.web.cern.ch/it-div-procurements/Download/powerbench.tar.gz
[Jon@TestNode powerbench]$ tar zxvf powerbench.tar.gzTake initial idle readings
- Let the system idle for 5~10 minutes to allow power and thermals to stabilise
- Measure the power consumption every 30 seconds for 5 minutes
- Measure Real Power (measured in Watts or W)
- Measure Apparent Power (measured in Volt-Amps or VA)
- Calculate Power Factor for each reading by dividing the Real Power by the Apparent Power. This will be a number between 0 and 1, hopefully above 0.8.
- Record an average for each of these figures
Start Powerbench
Start Powerbench running by executing the powerbench.sh script and wait 10 minutes before taking any readings:
[Jon@TestNode powerbench]$ sh powerbench.sh

Once the system has been running for 10 minutes, the script will prompt you to start taking readings:

Start reading the power consumption now- Measure the power consumption every 30 seconds for 5 minutes
- Measure Real Power (measured in Watts or W)
- Measure Apparent Power (measured in Volt-Amps or VA)
- Calculate Power Factor for each reading by dividing the Real Power by the Apparent Power. This will be a number between 0 and 1, hopefully above 0.95 for a modern PSU running near its maximum rating.
- Record an average for each of these figures
Kill Powerbench processes once completed
- Press CONTROL + C to exit the script
- Kill remaining processes:
[Jon@TestNode powerbench]$ killall lapack
