1. SPEC SERT

SPEC SERT is the next generation SPEC tool for evaluating the power and performance of server class computers.

The tool consists of several software modules:

  • Test harness - Chauffeur
  • Workloads
  • Power and Temperature Daemon (PTDaemon)

These modules work together in real-time to collect server power consumption and performance data by exercising the System Under Test (SUT) with predefined workloads.

1.1 Test harness - Chauffeur

The test harness (called Chauffeur): handles the logistical side of measuring and recording power data along with controlling the software installed on the SUT and controller system itself.

1.1.1 SERT Director

The Director reads test parameters and environment description information from the SERT configuration files and controls the execution of the test based on this information. It is the central control instance of the SERT and communicates with the other software modules described below via TCP/IP protocol. It also collects the result data from the worklet instances and stores them in the basic result file "results.xml".

1.1.2 SERT Host

This module is the main SERT module on the System Under Test (SUT). It must be launched manually by the tester and it starts the client modules executing the workloads under control of the Director.

1.1.3 SERT Client

One or more client instances each executing its own Java Virtual Machine (JVM) are started by the Host for every worklet. Each Client executes worklet code to stress the SUT and reports the performance data back to the Director for each phase of the test.

1.1.4 SERT Reporter

The reporter gathers the configuration, environmental, power and performance data from the "results.xml" file after a run is complete and compiles it into HTML and text or CSV format result files. It will be started automatically by the Director after finishing all workloads to create the default set of report files. Alternately it can be started manually to generate special report files from the information in the basic result file "results.xml".

1.1.5 SERT Graphical User Interface

A Graphical User Interface (GUI) to facilitate configuration and setup of test runs, allows real-time monitoring of test runs and to review the results is part of the test package. The SERT GUI leads the user through the steps of detecting or entering the hardware and software configuration, setting up a trial run or a valid test, displaying results reports and other functions common to the testing environment.

1.2 Workloads

The design goal for the SERT suite is to include all major aspects of server architecture, thus avoiding any preference for specific architectural features which might make a server look good under one workload and show disadvantages with another workload. The SERT workloads take advantage of different server capabilities by using various load patterns, which are intended to stress all major components of a server uniformly.

The SERT workloads consist of several different worklets, each stressing specific capabilities of a server. This approach furthermore supports generating individual efficiency scores for the different server components.

The worklets are built on synthetic tests which stress the different server components. Currently there are worklets for the following major server components:

  • CPU
  • Memory
  • Storage IO

For a detailed description of workloads and worklets please read the SERT Design Document.

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 the Director 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 SERT software module that is not Java based. Although it can be quite easily setup and run on a server other than the controller, it will typically reside on the controller.

1.4 Result Validation and Report Generation

At the beginning of each run, the test configuration parameters are logged in order to be available for later conformance checks. Warnings are displayed for any non-compliant properties and printed in the final report; however, the test will run to completion, producing a report that is not valid for publication.

At the end of a test 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 the test run. Basic validity checks are performed to ensure that interval length, target load throughput, temperature, etc. are within the defined limits. For more information see the section "Validation / Verification" in the SERT Design Document.

In this document all references to configurable parameters or result file fields are printed with different colors using the names from the configuration and result files:

Parameters from "test-environment.xml" are shown in red: <TestInformation><TestSponsor>

Parameters from "config-*.xml" or "*-configurations.xml" are shown in light purple: <suite><definitions><launch-definition><num-clients>

Parameters from "results.xml" are shown in green: <TestEnvironment><configuration><suite><client-configuration id>

The following configuration files are delivered with the test kit:

config-all.xml
The main SERT configuration file including the configurable parameters defining the execution of a SERT test run, e.g. the specification of storage test devices, durations of test intervals, enabling or disabling of workloads and/or worklets etc. Before editing this configuration file you should carefully read corresponding sections in the SERT User Guide, specifically section 6.1 "SERT Configuration and Start Procedure", see: https://www.spec.org/sert2/SERT-userguide.pdf.
config-all-expert.xml
An alternate version of the main SERT configuration file including extended configuration capabilities which can be used for non compliant modifications by experts. Please note that using this version of the main SERT configuration file will typically result in non compliant SERT runs. This file is meant for research usage by experienced SERT users.
config-rangeSetting.xml
This file includes definitions for an abbreviated SERT test with selected worklets and load levels only. It is intended to measure the maximum current for worklets and load levels in order to specify the amps range settings for the full SERT test. A description of how to use this configuration file is given in the SERT User Guide section "Power Analyzer Range Settings", see:https://www.spec.org/sert2/SERT-userguide.pdf.
config-development.xml
This file includes definitions for new worklets currently under development in additione to the default set of SERT worklets. Please note that using this version of the main SERT configuration file will result in non compliant SERT runs. It is intended for testing new worklets during the development phase. Currently configuration definitions for 2 experimental worklets, cpu_sleep and mem_flood_random, are available for testing.
listeners.xml
This file includes the interface and parameter definitions for possibly multiple PTDaemon instances and the Graphical User Interface (GUI). Especially the power analyzer range settings for the different worklets and load levels must be specified here.
test-environment.xml
This file includes a complete description of the SUT hardware and software. If the SERT is started via the GUI, some of the fields can be filled automatically from information found be the discovery scripts. The other fields must be edited manually by the tester.
client-configurations-NNN.xml
This file was introduced with the SERT V1.0.1 release. It specifies predefined sets of JVM options for the different architecture / operating system / JVM combinations to be used for running the tests. Starting with SERT V1.1.0 a version number is appended to the file name.

The authoritative versions of this file are located on the SPEC web site. For the current SERT version: https://www.spec.org/sert2/client-configurations-2.0.xml

A default version of this file is included in the SERT kit. The user must ensure that this local copy is up to date. If the local copy is outdated the latest version has to be downloaded from the SPEC web site location given above. The SERTUI provides support for downloading the current version of this file from the SPEC web site to the local SERT folder.

obsolete-client-configurations.xml
This file was introduced in SERT V1.1.0. Configurations in this file are obsolete and should not be used. They are retained here for the purpose of validating old results. Any modifications to this file will be detected and result in being unable to validate results.
custom-configurations.xml
Standard client configuration information supplied by SPEC is defined in the file "client-configurations-NNN.xml". This "custom-configurations.xml" file can contain custom configuration data for platforms that are not yet supported by SERT or for research and development purposes. Use of custom configuration data will result in non-compliant SERT runs. Configurations defined in this file will not be selected automatically in the SERT UI, but can be chosen manually by their id. For command-line runs, the client-configuration can be referenced by ID in "config-all.xml".

2. Main Report File

This section gives an overview of the information and result fields in the main report file "results.html/.txt".

The report file headline reads SERT™ Report. Previous SERT releases supported a separate category of results for 32-bit environments. The report file headline for such 32-bit configurations showed the addendum: (32-bit category). 32-bit results are no longer supported by the current release.

The predefined default values of the parameters in the "test-environment.xml" file are intentionally incorrect. To highlight this, all parameters are defined with a leading underscore. The Reporter recognizes this and highlights these fields with a yellow background, except for the system name in the headline of the general information table.


3. Top bar

The top bar gives general information regarding this test run.

The top bar header shows the name of the hardware vendor (see Hardware Vendor) plus the model name (see Model), potentially followed by a "(Historical System)" designation for systems which are no longer commercially available.

3.1 Test sponsor

The name of the organization or individual that sponsored the test. Generally, this is the name of the license holder.
<TestSponsor>

3.2 Software Availability

The date when all the software necessary to run the result is generally available.
<Software><Availability>

The date must be specified in the format: YYYY-MM

For example, if the operating system is available in 2013-02, but the JVM is not available until 2013-04, then the software availability date is 2013-04 (unless some other component pushes it out farther).

3.3 Tested by

The name of the organization or individual that ran the test and submitted the result.
<TestedBy>

3.4 Hardware/Firmware Availability

The date when all the hardware and related firmware modules necessary to run the result are generally available.
<Hardware><Availability>

The date must be specified in the format: YYYY-MM

For example, if the CPU is available in 2013-02, but the Firmware version used for the test is not available until 2013-04, then the hardware availability date is 2013-04 (unless some other component pushes it out farther).

For systems which are no longer commercially available the original availability date must be specified here and the model name must be marked with the supplement "(Historical System)" (see Model).

Please see OSG Policy section 2.3.5 on SUT Availability for Historical Systems: https://www.spec.org/osg/policy.html#s2.3.5

3.5 SPEC license #

The SPEC license number of the organization or individual that ran the test.
<SpecLicense>

3.6 System Source

Single Supplier or Parts Built.
<SystemUnderTest><SystemSource>

Single Supplier
a SUT configuration where all hardware is provided by a single supplier. For "Single Supplier" systems, all part description fields in the reports which require detailed information to identify the parts should include the system vendor name and the system vendor order number for the part.
Parts Built
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. For "Parts Built" systems all part description fields in the reports which require detailed information to identify the parts must include the part's manufacturer name and the manufacturer's part number to describe the devices.

3.7 Test Location

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

3.8 Test Date

The date on which the test for this result was performed. This information is provided automatically by the test software based on the timer function of the Controller system.

3.9 SERT Efficiency Score

This field was introduced in SERT V2.0.0.

It is intended for use in Energy Efficiency Regulatory Programs of government agencies around the world. This score is calculated as the weighted geometric mean of the individual workload efficiency scores of the CPU, Storage and Memory workloads (see also Workload Efficiency Score).

A more detailed description is given in the SERT Metric Document.


4 Summary

With SERT V2.0.0 an overall server efficiency score was introduced (see also SERT Efficiency Score).

4.1 Summary Chart

This chart was introduced in SERT V2.0.0.

A chart with a graphical representation of the individual workload and the overall server efficiency scores was added in this section.

Main attributes of the summary chart are:

Header
The model name of the System Under Test (SUT). It is included in the chart for explicit identification of this result, especially to enforce always showing the summary chart together with the tested SUT.
Y-axis
Vertical bars each representing one workload.
X-axis
A linear scale of numbers used for showing the workload and overall efficiency scores.

Note: The scaling of the data range on the x-axis can be different depending on the maximum value to be displayed. Therefore individual summary charts from different SERT result reports may not be directly comparable.

SERT Efficiency Score
The vertical green bar represents the overall SERT efficency score. The SERT efficiency score is also printed here again as a numerical value (see also SERT Efficiency Score).

Note: For invalid results the chart won't show any data.

4.2 Aggregate SUT Data

Aggregated values for several system configuration parameters are reported in this table.

4.2.1 Model

This field was introduced in SERT V2.0.0.

The model name identifying the system under test. The reported value is derived by the test software from the information given in the configuration files and by the test discovery scripts.

4.2.2 Number of Nodes

The total number of all nodes used for running the test. The reported values are calculated by the test software from the information given in the configuration files and by the test startup scripts.

4.2.3 CPU Name

This field was introduced in SERT V2.0.0.

Name of the tested CPU model. The reported value is derived by the test software from the information given in the configuration files and by the test discovery scripts.

4.2.4 Total Number of Processors

The number of processor chips per node. For multi node results the total number of all chips used for running the test is added. The reported values are calculated by the test software from the information given in the configuration files and by the test discovery scripts.

4.2.5 Total Number of Cores

The total number of all cores used for running the test. The reported value is calculated by the test software from the information given in the configuration files and by the test discovery scripts.

4.2.6 Total Number of Threads

The total number of all hardware threads used for running the test. The reported value is calculated by the test software from the information given in the configuration files and by the test discovery scripts.

4.2.7 Total Physical Memory

The total memory size for all systems used to run the test. The reported values are calculated by the test software from the information given in the configuration files and by the test discovery scripts.

4.2.8 Total number of memory DIMMs

This field was introduced in SERT V2.0.0.

The total number of DIMMs included in the tested SUT configuration. The reported value is calculated by the test software from the information given in the configuration files and by the test discovery scripts.

4.2.9 Total Number of Storage Devices

The total number of all storage devices used for running the test. The reported value is calculated by the test software from the information given in the configuration files and by the test discovery scripts.

4.3 Workload Efficiency Score

The efficiency score for each workload is calculated from the efficiency scores of all its worklets as:

Geometric Mean (Efficiency ScoreWorklet 1...n)

Efficiency scores for the different workloads can be extremely dissimilar due to configuration varietes, which may be favorable for some workloads only, e.g. additional DIMMs for the Memory workload or disk drives for the Storage workload. Typically these changes wouldn't influence the CPU workload score perceivably.

4.4 Idle Watts

The average-watts measured for the Idle worklet test interval (see also Watts at Lowest Load Level). By definition there is no performance value for the Idle worklet and therefore also no efficiency score can be calculated.

The Idle power is NOT included in the efficiency score calculation of the 3 workloads.


5. System under test

The following section of the report file describes the hardware and the software of the System Under Test (SUT) used to run the reported SERT results with the level of detail required to reproduce this result.

<SharedHardware><Firmware><Management><Version>

5.1.6 Power Supply Quantity (active / populated / bays)

This field is divided into 3 parts separated by slashes.

The first part shows the number of active power supplies, which might be lower than the next number, if some power supplies are in standby mode and used in case of failure only.
<SharedHardware><PowerSupplies><PowerSupply><Active>

The second part gives the number of bays populated with a power supply.
<SharedHardware><PowerSupplies><PowerSupply><Populated>

The third part describes the number of power supply bays available in the SUT enclosure.
<SharedHardware><PowerSupplies><Bays>

5.1.7 Power Supply Details

The number and watts rating of this power supply unit (PSU) plus the supplier and the part number to identify it.

In the case of a "Parts Built" system (see: System Source) the manufacturer name and the part number of the PSU must be specified here.
<SharedHardware><PowerSupplies><PowerSupply><Active>
<SharedHardware><PowerSupplies><PowerSupply><RatingInWatts>
<SharedHardware><PowerSupplies><PowerSupply><Description>

There may be multiple lines in this field if different types of PSUs have been used for this test, one for each PSU type.

5.1.8 Power Supply Operating Mode

Power supply unit (PSU) operating mode active for running this test. Must be one of the available modes as described in the field Available Power Supply Modes.
<SharedHardware><PowerSupplies><OperatingMode>

5.1.9 Available Power Supply Modes

<SharedHardware><PowerSupplies><AvailableModes><Mode>

Typical power supply modes are:

Standard
All populated PSUs are active
PSU Redundancy
N + M Spare PSU

For example: 2 + 1 Spare PSU

Two PSUs are active, the third PSU is inactive in Standby mode. System operation is guaranteed for 1 PSU fail in case of 3 PSUs in total.

AC Redundancy
N + N (2 AC sources)

For example: 2 + 2 (2 AC sources)

2 PSUs are active, the other two PSUs are inactive in Standby mode. 2 of the 4 PSUs are each connected to a separate AC source. This ensures that the system can continue operation even if a power line or a single PSU fails.

5.1.10 Network Switches (active / populated / bays)

This field is divided into 3 parts separated by slashes.

The first part shows the number of active network switches, which might be lower than the next number, if some network switches are in standby mode and not used for running the test.

5.3.10 Client Configuration ID (formerly SERT Client Configuration)

Beginning with SERT V1.0.1 this field shows the label of the client configuration element from the "client-configurations-NNN.xml" file specifying the predefined set of JVM options and number of clients to be used for running the tests.

A default version of this file is included in the SERT kit. The user has to ensure that this local copy is up to date compared to the master copy of this file available at:
https://www.spec.org/sert2/client-configurations-2.0.xml

If the local copy is outdated the latest version has to be downloaded from the SPEC web site location given above.

The correct option set for the given configuration is largely determined automatically by SERTUI based on the configuration parameters detected by the hardware discovery scripts. It's strongly recommended to manually check the detected parameters and the automatically selected option set for correctness.

If the SERT is started from command line the correct JVM option set for the given configuration must be specified manually in the "config-all.xml" file.

  • OS patches that affect performance and / or power.

Note: Disabling of OS services is disallowed (see section 2.4.5 "Software" of the SERT Run and Reporting Rules), and will invalidate the result.


7. Details Report File

The details report file "results-details.html/.txt" is created together with the standard report file at the end of each successful SERT run. In addition to the information in the standard report file described above it includes more detailed performance and power result values for each individual worklet.


8. Worklet Summary

This section describes the main results for all worklets in a table and as a graph. It is included in the details report file "results-details.html/.txt" only.

8.1 Result Chart

The result chart graphically displays the power, performance and efficiency scores for the different worklets. Each worklet is presented on a separate row beginning with the worklet name on the left. The lines are printed with distinct background colors for the different workloads:

  • light blue = CPU workload (including the SSJ worklet previously included in the Hybrid workload, which was removed for SERT 2.0.0)
  • light green = Storage workload
  • light red = Memory workload

The result chart is divided in three sections.

Watts
The leftmost section displays the range of measured power consumption for all load levels. The Watts values are given on vertical scales at the top of each workload section. The power range is represented by a blue line with a dot at the left for minimum power corresponding to the lowest load level and a dot at the right for maximum power corresponding to the highest load level. The intermediate load levels, if defined, are represented by small vertical bars. The vertical blue line across all worklets within each workload, named "Idle Power" represents the power consumption of the idle worklet. It does not correspond to any load.
Normalized Performance
The middle section displays the range of normalized performance values for all load levels. The normalized performance values are given on vertical scales at the top of each workload section. These values are calculated separately for each load level by taking the interval performance score and dividing it by the corresponding reference score for that worklet. The reference score for each worklet was determined taking the average performance score over several SERT test runs on a well defined reference configuration under different operating systems. The performance range is represented by a red line with a dot at the left for minimum performance corresponding to the lowest load level and a dot at the right for maximum performance corresponding to the highest load level. The intermediate load levels, if defined, are represented by small vertical bars.
Efficiency Score
The rightmost section displays the range of efficiency scores for all load levels. The efficiency scores are given on vertical scales at the top of each workload section. The efficiency scores are calculated separately for each load level by dividing the normalized-performance by the average-watts for that interval. The total efficiency score of a worklet is defined as the geometric mean of the efficiency scores of all its intervals (see also Worklet Efficiency Score). The efficiency score range is represented by a green line with a triangle at the left for minimum efficiency typically corresponding to the lowest load level and a triangle at the right for maximum efficiency typically corresponding to the highest load level. The intermediate load levels, if defined, are represented by small vertical bars.

8.2 Result Table

The result table numerically displays the power, performance and efficiency scores for the different worklets. Each worklet is presented on a separate row.

8.2.1 Workload

This column of the result table shows the names of the workloads. A workload may include one or more worklets.

8.2.2 Worklet

This column of the result table shows the names of the worklets the following values are belonging to.

8.2.3 Normalized Peak Performance

In order to get performance values in the same order of magnitude from all worklets the individual performance scores of each worklet (see Score) are divided by a fixed reference score. The reference score for each worklet was determined taking the average performance score over several SERT test runs on a well defined reference configuration under different operating systems.

The fields in this column show the normalized performance for the Peak Interval of each worklet only. The values are calculated by taking the Peak Interval performance score and dividing it by the corresponding reference score for that worklet.

8.2.4 Watts at Lowest Load Level

This column of the result table shows the worklet power readings at the lowest load level. Please note that this does not correspond to "Idle", which is implemented as a separate workload in SERT and not included in each worklet.

8.2.5 Watts at Highest Load Level

This column of the result table shows the worklet power readings at the highest load level, or "100%" load.

8.2.6 Geometric Mean of Normalized Performance

The worklet performance score is calculated as the geometric mean of the normalized performance scores over all measurement intervals of a worklet.

In order to get performance values in the same order of magnitude from all worklets the individual performance scores for each measurement interval of all worklets (see Score), are divided by a fixed reference score. The reference score for each worklet was determined taking the average performance score over several SERT test runs on a well defined reference configuration under different operating systems.

A detailed description of the normalization process is given in chapter 5.1 "The SERT Efficiency Metric" of the SERT Design Document.

8.2.7 Geometric Mean of Power (Watts)

The geometric mean of the average-watts over all measurement intervals (see Average Active Power (W) in the "Worklet Performance and Power Details" section).

8.2.8 Worklet Efficiency Score

The following formula is used to calculate the worklet efficiency scores for the current SERT version.

Worklet Efficiency Score = 1000 * Geometric Mean (EfficiencyInterval 1...n)

Efficiency for the Idle worklet is marked as not applicable (n/a) because the performance part is missing by definition.

Please note that Idle power is NOT included in the per worklet efficiency score calculation.

11. Worklet Performance and Power Details

This report section is available in the Details Report File "results-details.html/.txt" only. It is divided into separate segments for all worklets each starting with a title bar showing the workload and worklet names <workload name>: <worklet name>. Each segment includes Performance and Power Data tables together with some details about the client JVMs for the corresponding worklet.

11.1 Total Clients

Total number of client JVMs started on the System Under Test for this worklet.

Beginning with SERT V1.0.2 this number is calculated by the SERT code based on the information specified in the "client-configurations-NNN.xml" file. See Client Configuration ID for more details.

11.2 CPU Threads per Client

The number of hardware threads each instance of the client JVM is affinitized to.

11.3 Sample Client Command-line

The complete command-line for one of the client JVMs used to run this worklet, including affinity specification, the Java classpath, the JVM tuning flags and additional SERT parameters. The affinity mask, the "Client N of M" string and the "-jvmid N" parameter printed here are valid for one specific instance of the client JVM only. The other client JVMs will use their associated affinity masks, strings and parameters but share the rest of the commandline.

Beginning with SERT V1.0.2 the JVM tuning flags are included automatically by the SERT code based on the information specified in the "client-configurations-NNN.xml" file. See Client Configuration ID for more details.

11.4 Performance Data

This table displays detailed performance information for a worklet. The information is presented on separate rows per Phase, Interval and Transaction where applicable.

11.4.1 Phase

This column of the performance data table shows the phase names for the performance values presented in the following columns of the rows belonging to this phase.

Examples of phases are "Warmup", "Calibration" and "Measurement".

11.4.2 Interval

This column of the performance data table shows the interval names for the performance values presented in the following columns of the rows belonging to this interval.

Examples of intervals are "max" and "75%".

11.4.3 Actual Load

The "Actual Load" is calculated by dividing the interval "Score" by the "Calibration Result". This value is shown for the measurement intervals only. It can be compared against the target load level as defined by the "Interval" name.

11.4.4 Score

The fields in this column show the worklet specific score for each interval, which is calculated dividing the sum of all "Transaction Count" values for this interval by the "Elapsed Measurement Time (s)". For the calibration intervals a field showing the "Calibration Result" score is added in this column.

In contrast to the worklet performance score given in the performance data table Result Table above this score isn't normalized.

Note that elapsed interval time is the wall clock time specified in the SERT configuration file "config-all.xml" -- not the Transaction Time from the report.

The memory worklets (Flood3 and Capacity3) have their own score calculations that include other factors, e.g. memory capacity. A detailed description is given in the SERT Design Document https://www.spec.org/sert/SERT-designdocument.pdf.

With SERT release 2.0.0 the algorithm to calculate memory worklet scores has changed again. Therefore memory worklet scores from previous SERT releases are no longer comparable to those from SERT 2.0.0 and newer releases.

11.4.5 Host CV

This field was introduced in SERT V1.1.0.

The host CV (coefficient of variation) is calculated from all individual node performance "Scores" (Score) for the whole set of nodes (population). Individual CVs are shown in this column for each interval. Real values are calculated and displayed for multi node runs only. For single node runs "0.0%" is printed in all fields of this column.

The coefficient of variation (CV) is defined as the ratio of the standard deviation σ to the mean μ:

cv = σ ⁄ μ

It represents the extent of variability in relation to mean of the population. The calculated values are presented as percentage numbers in the SERT report files.

The Host CV is used by SERT to identify significant deviance of results of some nodes from the mean. Similar results per node are expected for a homogeneous set of nodes, i.e. the CV should be fairly small. High CV values indicate greatly different results for one or more nodes. CV values above certain thresholds will cause warnings or error messages being printed in the SERT result files.

11.4.6 Client CV

This field was introduced in SERT V1.1.0.

The Client CV (coefficient of variation) is calculated from all individual client performance "Scores" (Score) for the whole set of clients (JVM instances) including all nodes for multi node runs (population). Individual CVs are shown in this column for each interval.

The coefficient of variation (CV) is defined as the ratio of the standard deviation σ to the mean μ:

cv = σ ⁄ μ

It represents the extent of variability in relation to mean of the population. The calculated values are presented as percentage numbers in the SERT report files.

The Client CV is used by SERT to identify significant deviance of results of some clients from the mean. Typically similar results per client are expected, i.e. the CV should be fairly small. High CV values indicate greatly different results for one or more clients. For unbalanced configurations, e.g. different types of storage devices (HDD and SSD) or dissimilar amounts of memory attached to different processors, high CV values are "normal". CV values above certain thresholds will cause warnings or error messages being printed in the SERT result files. Warnings can be ignored for unbalanced configurations as high CV values are expected in this case.

11.4.7 Elapsed Measurement Time (s)

The time spent during this interval executing transactions. This is the time used for calculating the "Score" for this interval.

This time typically doesn't match exactly the interval time specified in the SERT configuration file "config-all.xml".

11.4.8 Transaction

The name of the transaction(s) related to the following "Transaction Count" and "Transaction Time" values.

Some worklets execute only one type of transaction whereas others, e.g. CPU: SSJ, run several different transactions. There will be a separate line for each transaction.

11.4.9 Transaction Count

The number of successfully completed transactions defined in column "Transaction" during the interval given in column "Interval".

For worklets including multiple transaction types a "sum" field is added, showing the aggregated transaction count for all transactions of this worklet.

11.4.10 Transaction Time (s)

The total elapsed (wall clock) time spent executing this transaction during this interval. It only includes the actual execution time, and not input generation time. Since multiple transactions execute concurrently in different threads, this time may be longer than the length of the interval.

For worklets including multiple transaction types a "sum" field is added, showing the aggregated transaction time for all transactions of this worklet.

11.5 Power Data

This table displays detailed power information for a worklet. The information is presented on separate rows per Phase and Interval. There will be separate power data tables for each power analyzer.

11.5.1 Phase

This column of the power data table gives the phase names for the power values presented in the following fields of the rows belonging to this phase.

The "Sum" field identifies the summary row for all measurement intervals (see Average Active Power (W)).

11.5.2 Interval

This column of the power data table gives the interval names for the power values presented in the following fields of the rows belonging to this interval.

The "Total" field identifies the summary row for all power analyzers (see Average Active Power (W)).

11.5.3 Analyzer

Name identifying the power analyzer whose power readings are displayed in this table. More details regarding this power analyzer are given in the Power Analyzer table(s) in the "Measurement Devices" section above.

11.5.4 Average Voltage (V)

Average voltage in Volts for each interval as reported by the PTDaemon instance connected to this power analyzer.

11.5.5 Average Current (A)

Average current in Amps for each interval as reported by the PTDaemon instance connected to this power analyzer.

11.5.6 Current Range Setting

The current range for each test phase as configured in the power analyzer. Typically range settings are read by PTDaemon directly from the power analyzer.

Please note that automatic current range setting by the analyzer is not allowed for all currently accepted analyzers and will invalidate the result.

11.5.7 Average Power Factor

Average power factor for each interval as reported by the PTDaemon instance connected to this power analyzer.

11.5.8 Average Active Power (W)

Average active power in Watts for each interval as reported by the PTDaemon instance connected to this power analyzer.

In this column a "Sum""Total" field is added, showing the aggregated active power for all measurement intervals over all power analyzers.

11.5.9 Power Measurement Uncertainty (%)

The average uncertainty of the reported power readings for each test phase as calculated by PTDaemon based on the range settings. The value must be within the 1% limit defined in section "1.20.1 Power Analyzer Requirements" of the SERT Run and Reporting Rules document.

For some analyzers range reading may not be supported. The uncertainty calculation may still be possible based on manual or command line range settings. More details are given in the measurement setup guide (see SPECpower_Measurement_Setup_Guide.pdf).

11.5.10 Minimum Temperature (°C)

The minimum ambient temperature for each interval as measured by the temperature sensor. All values are measured in ten second intervals, evaluated by the PTDaemon and reported to the test harness at the end of each interval.
