 +===== IO500 =====
  
-<io500>  +This is the list from Supercomputing 2020 compiled with the data announced by [[http://io500.org|IO500]].
-date=2017-11 +
-</io500>+
  
-===== IO500 List =====+The IO500 was supported by VI4IO and is now an independent activity. 
 +Please see for new lists the [[http://io500.org|IO500]] webpage.
  
-The above table shows the current IO500 list as of SC17.  By default the merely shows the top-level summary information.+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]]
  
-===== Expanding the table =====+The list shows the best result for a given combination of system/institution/filesystem.
  
-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. +<io500> 
- +date=2020-11 
-===== Adding custom columns ===== +list=io500 
- +version=v5 
-To add a custom (i.e. derived) column, merely enter an equation in the Equation field above. +radar=true 
- +controls=true 
-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: +</io500>
-  * 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: 
-  * score / client_nodes 
-  * bw / client_nodes 
-  * easy_create / client_nodes 
  
-====== Scoring information ======+[[https://www.vi4io.org/assets/io500/2020-11/data.csv|Download the complete data of the ranked 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-10.csv|Download the complete 10 Node Challenge list as CSV]]

-====== Submit for the next list ====== 
  
-Please consider submitting your own result to make it onto the next list! +//Values with* indicate that a value for the computation was missing.// \\ 
-Instructions are provided on the [[io500:submission|submission page]].+//§ these metadata scores are not compatible because of rule changes in SC19 [[https://github.com/VI4IO/io-500-dev/blob/master/CHANGELOG.md|Changelog]].
