Accepted Devices List

Accepted Measurement Devices

Multiple SPEC benchmarks provide infrastructure software to connect, control, and collect data from power and temperature measurement devices.  All measurement devices must be equipped with at least one of the communication interfaces supported by the benchmark.  When ordering devices for use with this benchmark, be aware that  some of these devices can be ordered in multiple configurations, including configurations with no interface or an unsupported communication interface.

Power analyzers are available with wide ranges of capabilities and capacities.  Computer systems have a wide range of power requirements.  Global standards for line voltage are quite different from one country to another.  Therefore, users should be aware that any one combination of the three above contributing factors may not provide the capability or required accuracy to measure very high or sometimes very low power.

The list of analyzers below have been tested and found to function well for a relatively narrow range of power provider and power consumption conditions, essentially for volume server class computers in the one to four socket range.   The list of accepted power analyzers below also indicates which analyzers have specific limitations which impact compliance with the run and reporting rules for SPEC benchmarks.  When using one of these analyzers, one must ensure that the listed limitations are not violated.  Results will be invalidated in cases where one of these analyzers was used and the system under test (SUT) exceeded the current limits of said analyzer. 

Prior to purchase of a power analyzer, SPEC recommends that the user consult with a qualified electrical engineer..

SPEC Acceptance Process for Power Analyzers
A process exists for a SPEC member or licensee to add software support for a power analyzer to the SPEC benchmark infrastructure and to submit tests for review and possible inclusion by SPEC as an accepted device.   Please see  http://www.spec.org/power_ssj2008/docs/SPECpower_ssj2008-Acceptance_Process.html  for the acceptance process.
