SPECpower_ssj® 2008 benchmark

SPEC.org Submission Requirements By location, as defined below
`SPEC Metrics`_
  • SPECpower_ssj®2008 overall ssj_ops/watt
  • for a specific target load level, its ssj_ops and Average Active Power(W).
`Required Metrics`_

SPECpower_ssj®2008 overall ssj_ops/watt

The required metric must be listed in `close proximity`_ to any other measured data from the disclosure or any `derived value`_.
Conditionally Required Metrics
  1. Condition:Comparison of performance or power data from the same target load level
    Requirement:Both the performance and the power results for that target load must be disclosed in close proximity
  2. Condition:Comparison of SUTs with different numbers of nodes
    Requirement:The number of nodes for each SUT must be disclosed in close proximity.
  3. Condition:Comparison of one target load level on one system and a different target load level on another system
    Requirement:The performance and power at the 100% target load level must be disclosed in close proximity
  4. Condition:Comparison of Active Idle points
    Requirement:The performance and power at the 100% target load level must be disclosed in close proximity
  5. Condition:Derived value based on a subset of performance and/or power information from a multi-node result
    Requirement:The number of nodes and the calculation method must be disclosed in close proximity.
Examples
  1. When fully loaded, Server X provides more performance and consumes less power than Server Y. Server X scores: (95,853 ssj_ops and 276W) @ 100% target load vs. Server Y: (40,852 ssj_ops and 336W) @ 100%. The SPECpower_ssj®2008 overall ssj_ops/watt are Server X: 203 and Server Y: 87.4 [1].
  2. Server X provides greater efficiency than Server Y. The SPECpower_ssj®2008 overall ssj_ops/watt for 4-node Server X is 203 and for 2-node Server Y is 87.4 [1].
  3. Server X does not pass 250W until near full load, whereas Server Y reaches it much earlier. Server X scores (79,346 ssj_ops and 252W) @ 90% target load while Server Y scores (8,237 ssj_ops and 254W) @ 30%. When fully loaded, Server X scores (95,853 ssj_ops and 276W) @ 100% and Server Y scores (40,852 ssj_ops and 336W) @ 100%. The SPECpower_ssj2008 overall ssj_ops/watt are Server X: 203 and Server Y: 87.4 [1].
  4. Server X uses only 50W at the Active Idle point, compared to 255W at Active Idle for Server Y. Server X scores (185,000 ssj_ops and 200W) @ 100% target load and Server Y scores (240,000 ssj_ops and 200W) @ 100%. The SPECpower_ssj®2008 overall ssj_ops/watt are Server X: 512 and Server Y: 450 [1].
  5. Server X provides better performance and uses less power than the individual nodes of Server Y. The single node server X scores (766 ssj_ops and 1,050W) @ 100% target load level. Server Y is a 10-node server which scores (2,550 ssj_ops and 10KW) @ 100% -- which means that on average each of the nodes uses (255 ssj_ops and 1000W) @ 100%. The SPECpower_ssj2008 overall ssj_ops/watt results are Server X: 415 and Server Y: 325 [1].

Use of `Estimates`_ Not allowed.
Disallowed Comparisons

In addition to the `requirements`_ that results not be compared to other benchmarks:

  • Comparisons may not be drawn between a Server and a Personal System. See the "System Designation" definitions in the `SPECpower_ssj2008 run rules`_
  • The calibration througputs must not be used (use the 100% target load level instead).
