  2. Agenda • Background / History • ECMA-383 1st edition (Plan A) • Issues with Plan A • Plan B proposal • Challenges with Plan B Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 2

  3. Background and History • Ecma International: an industry association founded in 1961, dedicated to standardization of ICT & CE products • http://www.ecma-international.org/ • Organisation membership from Asia, Europe and America • Companies, Research institutes, Single person companies • 2003: Ecma issued the world’s first environmentally conscious design standard (ECMA-341) • Aimed at the designer, provides pragmatic advice on how to reduce the environmental footprint of an ICT/CE product at the design stage. • ECMA-341 now available as IEC 62075. • Neither of these standards provide energy measurement criteria Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 3

  4. Ecma TC38-TG2 • In Q4/05, Ecma set up Task Group 2 within Technical Committee 38 to create energy [efficiency] standards • Initial scope was desktop and notebook computers • Kevin Fisher of Intel is the convenor • In order to ensure maximum transparency and a wide adoption of the work, Ecma agreed to the participation of non-Ecma member companies • Participants include: • IBM, HP, Dell, Toshiba, Gateway, Sony • Apple, Microsoft, Novell • Lexmark, Ricoh, Océ • Intel, AMD, nVidia, VIA technologies • Ecos, ICF, ITI, LBNL, Terra Novum • Observers include: • EPA (US), EC (EU), CSC (China) Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 4

  5. Energy environment for Computers • Voluntary and regulatory • Energy Star, TopRunner, EuP Lot 6 etc. • IEC 62301 exists today for measuring off mode. • The goal for Ecma TC38-TG2 was from the outset to determine a more holistic approach to measuring energy [efficiency] of computers. Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 5

  6. Plan A • Ecma TC38-TG2 embarked on Plan A • Three vectors required: • Energy consumption (annualised) • Capabilities • Performance • Require a benchmark to: • measure performance • enumerate capabilities • run workloads for measuring Active energy consumption • Require a set of criteria for compliant benchmarks Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 6

  7. Rational for the 3 vectors in Plan A Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 7

  8. Measuring Energy, Performance and Capabilities • Classifications: • Computer type: Notebook or Desktop • Workloads: Office productivity or Media Rich (others such as 3D or HD to be defined) • Duty cycle: How long is the machine doing work vs. idle or sleep? • Two key vectors: Power and Time • Historical emphasis has been on Power. The new concept was to place more emphasis on Time. Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 8

  10. Summary of the 1st edition ECMA-383 • Initial focus on Desktop and Portable Computers • Provides a consistent test methodology and reporting structure • In support of the standard a benchmark is required • Three components: • UUT workload classification: Rich media or office productivity • Performance and capability measurement • Energy consumption per workload and defined duty cycle Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 10

  11. Benchmark Criteria • The 1st edition of the Ecma Standard does not specify THE benchmark. • It provides criteria that a self declared benchmark must comply with • “Criteria for a benchmark that can be self declared by its developer to be used in support of the Ecma Standard: ECMA-383 1st Edition” • A benchmark developer would self declare compliance, inform Ecma who would add a link to their benchmark on the Ecma web site. • ECMA-383 provides the relevant Ecma url’s Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 11

  12. Problems with Plan A • The link with a benchmark has been problematic • Criteria for BM compliance complicated • Approval process open to criticism • Overheads to run the standard and benchmark high • Costs associated with BM purchase and renewal • Test time in excess of 1 hour • Performance vector complicated • How do you define Performance? • Difficulty in reaching agreement on performance measurement vector (e.g. the benchmark score) • Performance benchmarks already exist today • Simple enumeration of Capabilities does not allow for product to product comparisons • Three vectors as output: How do they all relate? Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 12

  13. Plan B required • Goals of plan B • Find replacement criteria for Performance to enable energy consumption comparisons of like machines • Reduce / remove the link to a benchmark • Provide a standard that can be used to measure power consumption in all energy states and report energy consumption over a given period of time (e.g. annualised) • Timescales for Plan B • Be ready for Ecma GA in December 2009 • Work in parallel with IEC TC108 WG Environment Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 13

  14. Plan B: The proposal • Replace the Capability and Performance vectors used in Plan A with a Categorisation vector • Enable the comparison of energy consumption of like for like machines • Categorisation details need to be defined. Examples would be: • Processor: # cores, # physical processors, cache etc • Audio: s/n ratio, # channels etc. • Graphics: size of memory, GPU capabilities etc • Memory: How big, how fast • Storage: Number and size of devices • Enable the standard to measure power in any or all power states: e.g. Off, Sleep, idle, active Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 14

  15. Plan B: The Benefits • Removed the link with a BM (however see next slide for Active power discussions) • The standard becomes simpler, faster and cheaper for user • More holistic standard for energy measurement • User can choose to measure power / energy in any power state, or: • Report overall energy consumption over a given period of time, and: • Compare like machines Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 15

  16. Plan B: The challenges • Categorisation: Not a new concept but will require much debate and comparison of ideas • Energy consumption in Active mode, two arguments: • On an annualised basis, the energy consumed in active is negligible therefore it could be considered as idle • In the coming years, idle time will reduce and so active energy will become more important • If active energy mode included: What workload to run to demonstrate real world active mode energy consumption? Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 16

  17. Plan B: Next steps • Define a roadmap for December completion • Categorisation and Active energy are risk factors • Solicit ideas from all members on Categorisation techniques • Agree how to handle Active power • Start basics of the standard (definitions, test flow etc) • Agree a working process between IEC and Ecma Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 17

  19. Address 4. ????? Thank you! Rue du Rhône 114 CH-1204 Geneva T: +41 22 849 6000 F: +41 22 849 6001 www.ecma-international.org Ecma is driven purely by the will of its members It is run by industry for industry, and is aware of your time and cost constraints Proven system for getting things done right and on time The know-how of the secretariat, GA and CC guides technical experts through international standardization jungle The Ecma process filters out non-commercial interests, resolves competitive clashes which are not productive The “fast track” by Ecma saves you time and money. If you get three members together for a project, it can not be stopped by other members Ecma works readily on several competing solutions to the same problem The development of an Ecma Standard takes (typically) no more than half the time required to develop a similar standard in any competing forum. Ecma Standards are recognized worldwide as amongst the highest quality Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 19
