[jira] [Commented] (MAHOUT-1942) Algorithms should be applicable to incore matrices

["Trevor Grant (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAHOUT-1942?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16060394#comment-16060394 ] 

Trevor Grant commented on MAHOUT-1942:
--------------------------------------

Move to close this as "won't fix"

It has become evident that majority of algorithms fall into one of two categories-

1) Highly parallelizable- an incore version is distributed out via a map/reduce function, the distributed version is simply a wrapper

2) A not Highly parallelizable- In which case the optimal implementation for the incore and distributed version differ significantly. 

By convention then, in the algorithms framework, models and fitters are presumed to be distributed unless `InCore` is the prefix of the class name.
