 +===== IO500 =====
  
-<io500 +This is the list from Supercomputing 2020 compiled with the data announced by [[http://io500.org|IO500]]. 
-date=2017-11 +The IO500 was supported by VI4IO and is now an independent activity. 
-</io500>+Please see for new lists the [[http://io500.org|IO500]] webpage.
  
-===== IO500 List =====+The current lists with links to the CDCL (as known) are available at: 
 +    * [[:io500:list:20-11:start|IO-500 list]]  
 +    * [[:io500:list:20-11:10node|10 Node Challenge list]] 
 +    * [[:io500:list:20-11:full|Full list]] 
 +    * [[:io500:list:20-11:historic|Historical list]]
  
-The above table shows the current IO500 list as of SC17.  By default the merely shows the top-level summary information.+The list shows the best result for a given combination of system/institution/filesystem.
  
-===== Expanding the table ===== +<io500> 
- +date=2020-11 
-To show more data, such as the individual benchmark scores, use the "Add column" drop-down box above.  There are shortcuts, such as ior.*, to add all of the individual benchmarks within a group.  The three groups are the bandwidth scores, as measured with ior, the metadata scores, as measured with mdtest, and the find scores (currently just one), as measured with the find utility. +list=io500

-===== Adding custom columns =====+radar=true 
 +controls=true 
 +</io500>
  
-To add a custom (i.e. derived) column, merely enter an equation in the Equation field above. 
  
-For equations you may use variables, i.e., use the group name of the metrics you want to use and replace space in the variable name with underscore, for example: +[[https://www.vi4io.org/assets/io500/2020-11/data.csv|Download the complete data of the ranked list as CSV]]
-  * io500.score information.client_nodes +
-  * io500.bw information.client_nodes +
-  * mdtest.easy_create information.client_nodes+
  
-If the metrics name is unambiguous, you may omit the group name, i.e., the following is valid: +[[https://www.vi4io.org/assets/io500/2020-11/data-10.csv|Download the complete 10 Node Challenge list as CSV]]
-  * score client_nodes +
-  * bw client_nodes +
-  * easy_create client_nodes+
  
-====== Scoring information ======+[[https://www.vi4io.org/assets/io500/2020-11/data-full.csv|Download complete data of the full list as CSV]]
  
-The score by which the ranking is computed is the 'score' column This 'score' column is merely the square root of the product of the 'bw' and 'md' scores The 'bw' score is the geometric mean of the IOR scores and the 'md' score is the geometric mean of the mdtest scores and the find scores.+[[https://www.vi4io.org/assets/io500/2020-11/data-historic.csv|Download the complete data of the historic list as CSV]]

-  * [[std:io500:start|For details of the approach, see the IO-500 effort]]+//§ these metadata scores are not compatible because of rule changes in SC19 [[https://github.com/VI4IO/io-500-dev/blob/master/CHANGELOG.md|Changelog]]

-====== Submit for the next list ======+Further lists with more detail can be found on the navigation menu. 
 +For example, a list with [[internal:io500:full|radar chart and configurable scoring]].
  
-Please consider submitting your own result to make it onto the next list!  Fetching, compiling, and running the IO500 Benchmarks is surprisingly straightforward.  Although tuning can be challenging.  Instructions for the former can be found in our [[https://github.com/VI4IO/io-500-dev|github repo]].  Help with the latter can be found in our various [[https://www.vi4io.org/std/io500/start#communication_contribution|communication channels]].
