Frequently Asked Questions

  1. When is the Green500 list going to be released?
    1. Currently, the Green500 has three releases per year: November, February, and June. The inaugural list was released on November 15, 2007 at SC|07. The second release was in February 28, 2008, and third release was on June 30, 2008. The next list will be released November 2008 during SC|08.
  2. Can I receive an embargoed pre-release?
    1. Unfortunately, no. At present, the Green500 is released shortly after the TOP500 and must be updated with new TOP500 entries. This precludes providing early lists.
  3. What trends do you see on the Green500 list? Which manufacturer does well?
    1. We currently don't have any trends. You may draw your own conclusions from the list itself.
  4. At publication time, will you be specific as to which form of power was used?
    1. Yes. We will use "measured power" if a formal submission is made here and if the number makes sense relative to the peak power rating. Furthermore, the list will indeed explicitly show whether measured or peak power was used. (Since "measured power" will be less than "peak power", it is advantageous to make a formal Green500 submission.)
  5. Which version of the TOP500 list are you planning to use the Green500 list? In other words, will the TOP500 list from June be used as your base line for the November Green500 list?
    1. We will use the TOP500 list for November to generate the November Green500 list, and the TOP500 June list for the Green500 June list. Therefore, there may be a slight delay between the TOP500 release and the Green500 release. For the February Green500 list, see the next question.
  6. Can you give me more details about the February Green500 list?
    1. The February list will use performance data from the November TOP500 list, but will include only new power submissions that were unavailable at the time of November Green500 release. We will use performance data from the November TOP500 list. We will not accept new performance data.
  7. There are many entries listed in the TOP500 list as anonymous. Can I do the same in the Green500 list?
    1. Yes, for now.
  8. Why don't you include the performance data from the TOP500 list on your site?
    1. The Green500 ranks systems by energy-efficiency (e.g., performance-per-watt). For performance rankings and information, we encourage you to visit the TOP500 website.
  9. Aside from the November, February, and June releases, is the Green500 subject to change?
    1. Our policy is to fix errors as soon as possible. A side effect of this policy is that the list may change between releases to fix errors.
