13. Set load to 100, and click OK.
14. Select Test Preferences from the Configuration menu item and set or verify the following by clicking
on each tab:
 Disk: select C: drive
 Logging: select Turn automatic logging on
 2D Graphics: select All available Video Memory
 3D Graphics: use defaults
 CPU: use defaults
15. Unpack the Linpack benchmark and adjust the number of instances, problem size, and leading
dimension size so that the CPU is at 100% utilization, and the memory is as close to 100% utilization
as possible. We used a batch file to run the number of instances we determined for each
workstation.
Running the test
1. Boot the system and launch PassMark BurnInTest by double-clicking the desktop icon.
2. Bring up an elevated command prompt:
a. Select Windows Start orb.
b. Type cmd and press Control-Shift-Enter.
3. Type Cmd.exe /c start /wait Rundll32.exe
advapi32.dll,ProcessIdleTasks
Do not interact with the system until the command completes.
4. After the command completes, wait 15 minutes before running the test.
5. Click Start Selected Tests in the BurnInTest V7.0 Pro screen, and double-click the Linpack benchmark
batch file.
6. Start the Fluke 2680A data logger using the Fluke DAQ software, and begin recording power with the
Extech Power Analyzer.
7. After 1 hour, stop the Fluke 2680A data logger using the Fluke DAQ software, and the Power
Analyzer data logger.
8. Export the thermal measurements to a CSV file. The Power Analyzer creates a CSV file as it collects
that data.
9. Use the thermal measurement CSV file to find and report the highest temperature measured at each
location during the test.
10. Use the Power Analyzer CSV to calculate the average power draw in watts during the test.
11. Power the workstation off for 1 hour, and allow it to return to room temperature.
12. Repeat the steps 1 through 11 two more times.
