>             Project: SystemML
>          Issue Type: Sub-task

>            Reporter: Matthias Boehm
>            Assignee: Matthias Boehm
>             Fix For: SystemML 1.0
> This task aims to support spark codegen instructions (for all templates) over 
> multiple RDD inputs if not all side inputs fit into the local and remote 
> broadcast memory budgets. In detail, this might entail either (1) generating 
> custom RDD operations and functions for various combinations of input RDDs, 
> or (2) a generalization of the related spark instructions regarding the input 
> RDD construction and a generic function signature.
