1. SPECpower_ssj2008 Benchmark

SPECpower_ssj2008 is the first generation SPEC benchmark for evaluating the power and performance of server class computers.
The benchmark suite consists of three separate software modules:

• Workload (SSJ)
• Power and Temperature Daemon (PTDaemon)
• Control and Collect System (CCS)

1.1 The Workload

1.1.1 Server Side Java Business Application Simulation

The workload is a Java program designed to exercise the CPU(s), caches, memory, the scalability of shared memory processors, JVM (Java Virtual Machine) implementations, JIT (Just In Time) compilers, garbage collection, threads, and certain aspects of the operating system of the SUT.
The workload architecture is a 3-tier system with emphasis on the middle tier. These tiers are comprised as follows:

1. Random input selection
2. Business logic (fully implemented by SPECpower_ssj2008)
3. Tables of objects, implemented by Java Collections (rather than a separate database)

1.1.2 JVM Director

The JVM Director is a separate and distinct mechanism from the actual workload itself (the three-tiered client-server environment), but runs concurrently with the JVM instance(s) of the workload. Like the workload, the JVM Director is also a java application, and as such, runs as its own JVM instance.
The JVM Director can be run locally on the SUT, or it can be run remotely at the user's discretion (see Director Location). Whichever method is employed, the JVM Director and the workload JVM instance(s) will communicate via a TCP/IP socket connection.

1.2 The Control and Collect System

The Control and Collect System is a Java-based application that resides on the controller server. CCS is used to connect to three types of data sources via TCP/IP socket communication:

• the SSJ module (via the JVM Director) on the SUT
• one ore more instances of PTDaemon each connected to a power analyzer
• one or more instances of PTDaemon each connected to a temperature sensor

1.3 The Power and Temperature Daemon

The Power and Temperature Daemon (PTDaemon) is a single executable program that communicates with a power analyzer or a temperature sensor via the server's native RS-232 port, USB port or additionally installed interface cards, e.g. GPIB. It reports the power consumption or temperature readings to CCS via a TCP/IP socket connection. It supports a variety of RS-232, GPIB and USB interface command sets for a variety of power analyzers and temperature sensors. PTDaemon is the only of the three SPECpower_ssj2008 software modules that is not Java based. Although it can be quite easily setup and run on a server other than the controller server, in the simplest SPECpower_ssj2008 test bed implementation, the PTDaemon will typically reside on the controller server.

1.4 Result Validation and Report Generation

At the beginning of each run, the benchmark parameters are checked for conformance to the run rules. Warnings are displayed for non-compliant properties and printed in the final report; however, the benchmark will run to completion producing a report that is not valid for publication.
At the end of a benchmark run the report generator module is called to generate the report files described here from the data given in the configuration files and collected during this benchmark run. Again basic validity checks are performed, to ensure that interval length, target load throughput, temperature etc. are within the limits defined in the run rules. For more information see section "2.5.2 Validity Checks" in the Run and Reporting Rules document.

1.5 References

More detailed information can be found in the documents shown in the following table. For the latest versions, please consult SPEC's website.

2. Main Report File

This section gives an overview of the information and result fields in the main report file. Additional information is shown in the Power/Temperature Details Report, including detailed power information for potentially multiple power analyzers, and the Aggregate Performance Report, which is generated for multiple node tests only. The Set Performance Report represents the next level of details and is created only if multiple heterogeneous sets of nodes are used, which is currently not allowed for valid results. This information is further extended in the Host Performance Report and the JVM Instance Performance Report which are generated for each host and each JVM instance including specific configuration and performance details.

3. Top bar

The top bar shows the measured SPECpower_ssj2008 result and gives some general information regarding this test run.

3.1 Headline

The headline of the performance report includes one field displaying the hardware vendor (config.hw.vendor) and the name (config.hw.model) of the system under test. If this report is for a historical system the declaration "(Historical)" must be added to the model name. In a second field the overall SPECpower_ssj2008 result achieved in this test (overall ssj_ops/watt) is printed, eventually prefixed by an "Invalid" indicator, if the current result does not pass the validity checks implemented in the SPECpower_ssj report generation software. More detailed information about the result metric is presented in section 3.1 of the SPECpower_ssj2008 Run and Reporting Rules.

3.2 Test sponsor

The name of the organization or individual that sponsored the test. Generally, this is the name of the license holder (config.test.sponsor).

3.3 SPEC license #

The SPEC license number of the organization or individual that ran the result (config.test.spec_license).

3.4 Hardware Availability

The date when all the hardware necessary to run the result is generally available (config.hw.available). For example, if the CPU is available in Aug-2007, but the memory is not available until Oct-2007, then the hardware availability date is Oct-2007 (unless some other component pushes it out farther).

3.5 Tested by

The name of the organization or individual that ran the test and submitted the result (config.test.tested_by).

3.6 Test Location

The name of the city, the state and country the test took place. If there are installations in multiple geographic locations, that must also be listed in this field (config.test.location).

3.7 Software Availability

The date when all the software necessary to run the result is generally available (config.sw.available). For example, if the operating system is available in Aug-2007, but the JVM is not available until Oct-2007, then the software availability date is Oct-2007 (unless some other component pushes it out farther).

3.8 System Source

Single Supplier or Parts Built (config.hw.system_source)

• Single Supplier
  "Single Supplier" is defined as a SUT configuration where all hardware is provided by a single supplier.
• Parts Built
  "Parts Built" is defined as a SUT configuration where hardware is provided by multiple suppliers. A "Parts Built" system disclosure must include enough detail to procure and reproduce all aspects of the submission, including performance and power.

3.9 Test Date

The date when the test is run. This value is automatically supplied by the SPECpower_ssj software; the time reported by the system under test is recorded in the raw result file .

3.10 Publication Date

The date when this report will be published after finishing the review. This date is automatically filled in with the correct value by the submission tool provided by SPEC. By default this field is set to "Unpublished" by the software generating the report.

3.11 Test Method

Possible values for this property (config.test.method) are:

• Single Node
  "Single Node" is defined as a SUT configuration where the test is performed on one server running a single OS image (see section 2.11 of the SPECpower_ssj2008 Run and Reporting Rules).
• Homogeneous Multi Node
  "Homogeneous Multi Node" is defined as a SUT configuration where the test is running on multiple, identically configured ("homogeneous") servers sharing some energy efficiency feature (see section 2.11 of the SPECpower_ssj2008 Run and Reporting Rules).
• Heterogeneous Multi Node (Not Valid for Publication)
  "Heterogeneous Multi Node" this SUT configuration is composed of multiple, differently configured ("heterogeneous") servers sharing some energy efficiency feature (see section 2.11 of the SPECpower_ssj2008 Run and Reporting Rules).

3.12 System Designation

Possible values for this property (config.hw.system_designation) are:

• Server
  "Server" is defined as a computer system that is marketed to support multiple tasks from multiple users, simultaneously. (see section 3.3.2 of the SPECpower_ssj2008 Run and Reporting Rules).
• Personal System
  "Personal System" is a computer system that is primarily marketed for use by a single individual, even though multiple tasks may execute simultaneously (see section 3.3.2 of the SPECpower_ssj2008 Run and Reporting Rules).

• Battery-powered
  A computer system designed to be able to run normal operations without an external source of power (see section 2.8 of the SPECpower_ssj2008 Run and Reporting Rules).

3.14 INVALID

Any inconsistencies with the run and reporting rules causing a failure of one of the validity checks implemented in the report generation software will be reported here and all pages of the report file will be stamped with an "Invalid" water mark in case this happens. The printed text will show more details about which of the run rules wasn't met and the reason why. (see section 2.5.2 of the SPECpower_ssj2008 Run and Reporting Rules).

4 Performance Results Summary

This section describes the result details for all measurement intervals in a table and as a graph.

4.1 Performance

The first three columns of the results table show the measured throughput and the actual percentage of calibrated throughput compared to the target percentage.

4.1.1 Target Load

The different target load levels derived from the calibrated throughput, starting with 100% of the calibrated throughput and decreasing to "Active Idle" = 0% or no throughput. The benchmark software schedules the required number of requests to actually achieve the intended throughput levels during each of the measurement intervals, each lasting 240 seconds.

4.1.2 Actual Load

The load levels actually achieved during the different phases of the benchmark as a percentage of the calibrated throughput. The percentages must match the target load of each phase with less than 2% deviation (positive or negative).

4.1.3 ssj_ops

The number of operations finished during this measurement interval divided by the number of seconds defined for this interval, showing the throughput (workload operations per second) for this period.

4.1.4 Active Idle

The last measurement interval running without any transactions scheduled by the workload software. So there is no throughput reported for this interval only the power consumption will be measured and displayed.

4.2 Power

This column of the results summary table shows the power consumption for the different target loads.

4.2.1 Average Active Power (W)

Average active power measured by the power analyzer(s) and accumulated by the PTDaemon (Power and Temperature Daemon) for this measurement interval, displayed as watts (W).

4.3 Performance to Power Ratio

The average throughput divided by the average power consumption for each of the measurement intervals.

4.4 ∑ssj_ops / ∑power =

4.5 Result Chart

The result chart graphically displays the results reported in the summary table in one diagram. The red bars show the performance to power ratio (throughput / W) of each target load given on the y-axis graphically (corresponding to the upper x-axis) and numerically as a label in the bar. Longer bars / higher numbers are better. By definition there is no throughput for the "Active Idle" level and so the ratio is always 0. The bold blue line with the markers corresponds to the lower x-axis and shows the average power consumption for each target load given on the y-axis. Lower numbers are better. The thin, vertical, straight line corresponds to the upper x-axis and shows the overall ssj_ops per watt result of the benchmark. A higher number is better.
