khannaekta opened a new pull request #459: DL: Add support for asymmetric segment distribution to preprocessor
URL: https://github.com/apache/madlib/pull/459
 
 
   JIRA: MADLIB-1392
   
   This commit adds a new parameter `distribution_rules`, to the functions
   `training_preprocessor_dl()` and `validation_preprocessor_dl()`. This
   parameter specifies how to distribute the `output_table` on the cluster,
   `all_segments` being the default value. This change adds a new column to
   the output summary table `gpu_config`, containing values based on the
   input `distribution_rules`.
