This document provides an overview of how the Mahout Scala DSL (distributed
algebraic operators) is implemented over the H2O backend engine. The document
is aimed at Mahout developers, to give a high level description of the design
so that one can explore the code inside `h2o/` with some context.
-## [H2O](http://h2o.ai/) Overview
+## H2O Overview
H2O is a distributed scalable machine learning system. Internal architecture
of H2O has a distributed math engine (h2o-core) and a separate layer on top for
algorithms and UI. The Mahout integration requires only the math engine
(h2o-core).

Within mahout.git, the top level directory, `h2o/` holds all the source code
related to the H2O backend engine. Part of the code (that interfaces with the
rest of the Mahout componenets) is in Scala, and part of the code (that
interfaces with h2o-core and implements algebraic operators) is in Java. Here
is a brief overview of what functionality can be found where within `h2o/`.
