Published 4 times per year, the TPC Benchmark Status Report is a digest of the activities of the TPC and its technical subcommittees.

The TPC held a General Council meeting on September 2nd in Chicago, IL. The TPC-H Maintenance Subcommittee posted version 2.12.0 which corrected the 30TB and 100TB dbgen problems and made enhancements to dbgen to disallow dangerous or malfunctioning options. The Energy Subcommittee updated the TPC-Energy specification to version 1.2.1 to further clarify some definitions and to change some audit verifications. Finally, the TPC-Virtualization Development Subcommittee has progressed its activities from creating a specification draft to prototyping.

The TPC-C Maintenance Subcommittee had no outstanding issues to discuss at the meeting. The subcommittee will continue to monitor the benchmark, along with any TAB interpretations and rulings, for discussion and possible inclusion in future versions of the TPC-C specification.

The TPC-H Maintenance Subcommittee posted revision 2.12.0 which corrects the 30TB and 100TB dbgen problems and disallows many dangerous or malfunctioning dbgen options and option combinations. TPC-H version 2.11.0 became obsolete on October 31st 2010.

Work continues on upcoming revisions while discussion on a major revision (3.0) has begun.

The TPC-E Maintenance Subcommittee had no outstanding issues to discuss at the meeting. The subcommittee will continue to monitor the benchmark, along with any TAB interpretations and rulings, for discussion and possible inclusion in future versions of the TPC-E specification.

The ETL benchmark subcommittee is continuing to develop various aspects of the specification. There has been progress on setting the data scaling rules, defining the benchmark metrics and determining what a qualifying implementation is. The subcommittee expects to send out an RFP for the development of the data generator. Interested parties should contact the TPC Administrator.

The second TPC Technology Conference on Performance Evaluation and Benchmarking (TPCTC 2010) was a big success. The papers and keynotes will be posted to the web site shortly. The TPC is encouraging industry experts and researchers to submit novel ideas and methodologies in performance evaluation, measurement and characterization for 2012 and beyond. Conference information is available at www.tpc.org/tpctc/tpctc2010.

The TPC-Virtualization Development Committee is moving forward from a draft specification to data that can determine the practicality of the design. Prototyping tasks have been identified and assigned, with several member companies about to begin prototyping.

Organizations that are interested in influencing the TPC-Virtualization benchmark are encouraged to become members.

The TPC Energy sub-committee has updated the specification to version 1.2.1 which clarifies some clauses and adds definitions. The TPC-Energy Specification 1.2.1 has been approved by the TPC membership and is now the current version of TPC-Energy Benchmark Specification.

The Energy Measurement System (EMS) is at revision 1.2.0 and has no additional changes from the previous release.

TPC-Energy results continue to be published on all TPC-Benchmarks (TPC-C, TPC-H, and TPC-E). The TPC web-site has these results posted and the Executive Summaries and Full Disclosure Reports are available for downloading (accessible via the Results Detail web page).

Version 1.5.0 of the Pricing Specification is currently required for all TPC benchmarks. The Price Maintenance Committee has no requests for changes of the current version of the specification.

Most of the queries available on www.tpc.org have been tailored for mobile devices and are accessible at 'obsolete link'. Due to the reduced real estate on mobile devices some of the information available on the regular web site had to be dropped, but we believe that the new mobile links will be a valuable source for finding benchmark results on your mobile device.

We welcome opportunities to present the benefits and status of TPC benchmarks: if you are interested in inviting someone from the TPC for a presentation, please contact Michael Majdalany (majdalany @ tpc.org)
