SPECapc Project Group Rules

The Application Performance Characterization Project Committee Rules

Version 2.19

Last Updated: 07/28/2014

Overview
1. General Philosophy
  1. All rules declared in "The Graphics and Workstation Performance Group (SPEC/GWPG): Rules For Project Groups" document (known hereafter as the GWPG Project Groups Ruleset) apply, unless specifically overruled by a rule in this document.
2. General Philosophy
  1. Within SPEC's Graphics and Workstation Performance Group (SPEC/GWPG) there was a strong belief that it is important to benchmark graphics performance based on actual applications. Application-level benchmarks exist, but they are not standardized and they do not cover a wide range of application areas. Thus, the Application Performance Characterization (SPECapc^SM) Project was created within the GWPG to create a broad-ranging set of standardized benchmarks for graphics-intensive applications.
  2. The SPECapc seeks to develop benchmarks for generating accurate application-level graphics performance measures in an open, accessible and well-publicized manner.
  3. The SPECapc wishes to contribute to the coherence of the field of application performance measurement and evaluation so that vendors will be better able to present well-defined performance measures and customers will be better able to compare and evaluate vendors products and environments.
  4. The SPECapc will provide formal beta benchmarks to members and final benchmark releases to the public in a timely fashion.
  5. Hardware and software used to run the SPECapc benchmarks must provide a suitable environment for running typical (not just benchmark) workloads for the applications in question.
  6. SPECapc reserves the right to adapt its benchmarks as it deems necessary to preserve its goal of fair and useful benchmarking (e.g. remove benchmark, modify benchmark code or data, etc). If a change is made to the suite, SPECapc will notify the appropriate parties (i.e. SPECapc members and users of the benchmark) and SPECapc will re-designate the benchmark by changing its name and/or version. In the case that a benchmark is removed in whole or in part, SPECapc reserves the right to republish in summary form "adapted" results for previously published systems, converted to the new metric. In the case of other changes, such a republication may necessitate re-testing and may require support from the original test sponsor.
3. Overview of Optimizations
  1. SPECapc is aware of the importance of optimizations in producing the best system performance. SPECapc is also aware that it is sometimes hard to draw an exact line between legitimate optimizations that happen to benefit SPECapc benchmarks and optimizations that specifically target SPECapc benchmarks. However, with the list below, SPECapc wants to increase awareness of implementers and end-users to issues of unwanted benchmark-specific optimizations that would be incompatible with SPECapc's goal of fair benchmarking.
  2. To ensure that results are relevant to end-users, SPECapc expects that the hardware and software implementations used for running SPECapc benchmarks adhere to a set of general rules for optimizations.
4. General Rules for Optimization
  1. Optimizations must generate correct images and results for the application under test, for both the benchmark case and similar cases. Correct images and results are those deemed by the majority of the SPECapc electorate, potentially with input from the associated independent software vendor (ISV) and/or end-users, to be sufficiently adherent to the intent behind the application.
  2. Optimizations must improve performance for a class of workloads where the class of workloads must be larger than a single SPECapc benchmark or SPECapc benchmark suite.
  3. For any given optimization a system should generate correct images with and without said optimization. An optimization should not reduce system stability.
  4. The vendor encourages the implementation for general use (not just for running a single SPECapc benchmark or SPECapc benchmark suite).
  5. The implementation is generally available, documented and supported by the providing vendor.
  6. In the case where it appears that the above guidelines have not been followed, SPECapc may investigate such a claim and request that the optimization in question (e.g. one using SPECapc benchmark-specific pattern matching) be removed and the results resubmitted. Or, SPECapc may request that the vendor correct the deficiency (e.g. make the optimization more general purpose or correct problems with image generation) before submitting results based on the optimization.
  7. It is expected that system vendors would endorse the general use of these optimizations by customers who seek to achieve good application performance.
  8. No pre-computed (e.g. driver-cached) images, geometric data, or state may be substituted within an SPECapc benchmark on the basis of detecting that said benchmark is running (e.g. pattern matching of command stream or recognition of benchmark's name).
Benchmarks
1. Benchmark Acceptance
  1. Benchmark components are defined as
    1. specific revision of an application,
    2. run rules, scripts and associated data sets.
  2. New or modified benchmark components require a 2/3-majority vote to be accepted for publication. Selection of datecode versions of a specific revision of an application is by majority vote.
  3. A minimum 3-week review period is required for new or significantly modified benchmark components.
  4. At the end of the review period a vote will be called to approve the proposed changes.
  5. An amendment to a benchmark component during the review period must be unanimously accepted. If not, the review period shall be restarted.
2. Benchmark Code Versioning
  1. Benchmarks use the following version coding: M.m (e.g. SPECapc^SM for Pro/ENGINEER 20.0 v1.1) M is the major release number and m is the minor release number.
  2. The major release number is only incremented when large amounts of code are changed and the scripting language is dramatically changed as a result -- backward compatibility is highly unlikely when moving scripts or data sets between major releases (e.g. running v2 scripts on a v3 executable would almost certainly fail).
  3. The minor release number is bumped if some small set of code is replaced or removed - but the standard, unchanged scripts and data sets, as a whole, must run on the new version (but perhaps with different performance).
  4. When there is a new major release of a benchmark, submissions using the previous release will be accepted for at least one submission cycle. When a superceded benchmark is retired, the associated run-rules will be archived in an "archived benchmark run-rules document" posted on the Previous SPECapc Benchmarks web-page.
Submission, Review and Publication
1. General Benchmark Run Rules
  1. The system under test must correctly perform all of the operations being requested by the application during the benchmark.
  2. No changes to any files associated with the benchmark are permitted excepted as noted in the benchmark-specific rules (section 5 of this document).
  3. The entire display raster must be available for use by the application being benchmarked.
  4. It is not permissible to override the intended behavior of the application through any means including, but not limited to, registry settings or environment variables.

  6. The system under test can not skip frames during the benchmark run.
  7. It is not permissible to change the system configuration during the running of a given benchmark. That is, one can't power off the system, make some changes, then power back on and run the rest of the benchmark.
  8. Results submitted must be obtained using the scripts, models, and application revisions which are specified for that submission cycle by the SPECapc.
  9. The color depth used must be at least 24 bits (true color), with at least 8 bits of red, 8 bits of green and 8 bits of blue, unless otherwise specified.

  13. The monitor used in the benchmark must support the stated resolution and refresh rate.
  14. The benchmark must successfully obtain all requested window sizes, with no reduction or clipping of any benchmark-related windows. Windows created by the benchmark must not be obscured on the screen by anything other than other elements created by the benchmark.
  15. Tests may be run with or without a desktop/window manager if the application allows this, but must be run on some native windowing system.
  16. It is not permissible to interact with the system under test to influence the progress of the benchmark during execution.
