Maximum Power Test for Workstations. The maximum power for workstations is found by the simultaneous operation of two industry standard benchmarks: Linpack to stress the core system (e.g., processor, memory, etc.) and SPECviewperf® (latest available version for the UUT) to stress the system's GPU. Additional information on these benchmarks, including free downloads, can be found at the URLs found below: Linpack xxxx://xxx.xxxxxx.xxx/linpack/ SPECviewperf® xxxx://xxx.xxxx.xxx/benchmarks.html#gpc This test must be repeated three times on the same UUT, and all three measurements must fall within a ± 2% tolerance relative to the average of the three measured maximum power values. Measurement of the maximum AC power consumption of a workstation should be conducted as follows:
1. Connect an approved meter capable of measuring true power to an AC line voltage source set to the appropriate voltage/frequency combination for the test. The meter should be able to store and output the maximum power measurement reached during the test or be capable of another method of determining maximum power.
2. Plug the UUT into the measurement power outlet on the meter. No power strips or UPS units should be connected between the meter and the UUT.
3. Record the AC voltage.
4. Boot the computer and, if not already installed, install Linpack and SPECviewperf as indicated on the above Websites.
5. Set Linpack with all the defaults for the given architecture of the UUT and set the appropriate array size "n" for maximising power draw during the test.
6. Ensure all guidelines set by the SPEC organisation for running SPECviewperf are being met.
7. Set the meter to begin accumulating true power values at an interval no more than one reading per second, and begin taking measurements. Run SPECviewperf and as many simultaneous instances of Linpack as needed to fully stress the system.
8. Accumulate power values until SPECviewperf and all instances have completed running. Record the maximum power value attained during the test.
9. The test results must be reported to the EPA or the European Commission, as appropriate, taking care to include all required information.
10. Upon submittal of data, manufacturers must also include the following data:
a. Value of the n (the array size) used for Linpack,
b. Number of simultaneous copies of Linpack run during the test,
c. Version of SPECviewperf run for test,
d. All compiler optimisations used in compiling Linpack and SPECviewperf, and
e. A precompiled binary for end users to download a...
