      19. Subsequent to publication, any change to or replacement of elements for a submitted configuration must not result in more than a 5% performance degradation in the submitted benchmark results. Upon demonstration of such a degradation, the submitted results for this configuration will be removed from the SPEC public website.

      20. On or before the date of publication, the submitted configuration shall be available for purchase by the public, for the specified price or less, with a firm delivery date of 60 days or less. Submissions will be categorized as either “Single Supplier” or “Multiple Supplier”, where “Single Supplier” is defined as a configuration where all hardware, OS, and drivers are sold and supported by the submitting supplier. “Supported” is defined as providing hardware, drivers and associated technical support, and that the drivers are available from the system supplier. “Multiple Supplier” is defined as a configuration built and supported by multiple suppliers.

      21. “Multiple supplier” system pricing must include enough detail to reproduce all aspects of the submission, including performance and price, and include all hardware and O/S costs necessary to run benchmark.

      22. For all benchmarks, the submitted result file must contain the exact performance results as generated by the benchmark. Fields carrying performance results may not be altered.
    3. Submission Process Rules

      1. Each benchmark is considered a separate submission.

      2. Submissions of each benchmark's results (e.g. Maya6.5™, Solidworks 2007™, SPECviewperf, etc.) must be in separate tar/zip files.

      3. A submitter of benchmark results must upload his or her submission to the proper server location by the submission deadline date and time. The submitter must not create any new directories on the server when uploading the submission.

      9. If a submitter is notified that their submission format is incorrect, they must re-send their submission in proper format within 3 business days of notification.

    4. Review Period Rules

      1. SPEC/GWPG project group members shall keep all submitted results confidential to the respective project group until those results appear on the public SPEC web site. The exception to this rule is that members are free to make their own submitted results public at any time.

      2. SPEC Office assigns reviewers to submitters. Reviewers must acknowledge the assignment by email to the SPEC office. If no acknowledgments are received by end of the second day of the review period, the SPEC office will reassign reviewers.

      3. Members who wish not to review the submission of other specific members due to conflict of interest must submit that list to the SPEC office prior to the submission deadline. The SPEC office will hold the list in confidence from other members.

      4. The various SPECapc and SPECgpc pools of eligible reviewers will be independent of each other. The SPEC office will send the list of contact information for the submissions under review.

      5. All members will have access to all benchmark submissions once the review period begins.

      6. The review period shall be 5 calendar days.

      9. Any reviewer who has one or more questions relating to a submission must:

        1. Pose the question(s) to the submitter and cc the primary reviewer, OR

        2. Pose the question(s) to the primary reviewer. The primary reviewer must then pose the question(s) to the submitter, OR

        3. Pose the question(s) to an officer of the respective project group. The officer must then pose the question(s) to the submitter and cc the primary reviewer

      10. With permission of the primary reviewer, as communicated through the respective project group's email alias, the submitter can request that their submission be rejected on stated technical grounds.

      11. With permission of the primary reviewer, as communicated through the respective project group's email alias, a submitter may resubmit a submission to resolve issues found during the review process. The submitter must notify the respective project group's mailing list with the date and version of the resubmitted file(s).

      12. The submitter must provide the primary reviewer access to the system under test at the submitter's facilities if requested by the reviewer during the review period. The reviewer must state prior to the visit what part of the submission is going to be verified. Travel expenses are the responsibility of the reviewer.

      13. If the reviewer disputes the stated pricing, the submitter must provide documentation that the system can be purchased for the price quoted.

      14. By the end of the review period, the primary reviewer of a submission must designate the status of the submission one of: “accepted without comment”, "accepted with comment", “pending with comment”, or “rejected with comment”. The submitter may appeal a rejection as described in "Review Appeal Rules" below.

      15. Any comments for rejection of a submission received after the end of the review period will not delay publication of the submission.

      16. A submission designated “pending with comment” will not go public and will remain pending until the submitter addresses all comments. Once the comments are addressed the web master will post to the public site. Any member who feels comments are not satisfactorily addressed may challenge the submission according to Section IV.6 for challenging approved results.

      17. If a submitter repeatedly makes submissions that are non-compliant or which do not address concerns identified in the previously-assigned reviewers' rejection comments, the reviewer may engage the committee to solicit appropriate action, which may be up to and including an embargo on submissions from that submitter for a period of time.

    5. Review Appeal Rules

      1. The appeal period shall have the same duration as one submission cycle, and shall immediately follow the review period.

      2. Any submitter of a rejected submission can make their case to the respective project group's email alias during the appeal period.

      3. At the end of the appeal period, if there is no resolution, the project group Chair shall call a vote to accept or reject the submission.

      4. The project group electorate votes on accepting or rejecting an appealed submission. A simple majority is required to accept or reject the appeal. In case of a tie the submission is rejected.

    6. Challenging Accepted Results

      1. Any member may challenge accepted results at any time. This includes:

        1. archived results,

        2. currently published results, and

        3. resubmitted results not subject to the regular submission review process.

      2. The burden of proof that the result should be modified is on the member who is challenging the result.

      3. The challenge must be ratified by a majority vote of the project group's electorate.

      4. The project group Chair will call a special review cycle for a resubmission in the event that there is a ratified challenge to currently published results.

      5. A ratified challenge to archived results can only result in annotation, not removal or modification. The annotation will be determined by the majority of the electorate. It is the responsibility of the challenger to verify that the results have been annotated correctly on the public website within two working days from the ratification of the challenge.

  4. Publication Rules

    1. Official Publication

      1. Benchmark results for publication by the SPECgpc or the SPECapc must adhere to Articles concerning "Overview", "Benchmark Run Rules" and "Submission and Review Rules" as presented in this document AND the respective project group's rules document.
