SystemML 0.15
> Full aggregation support in rowwise templates
> ---------------------------------------------
>
> Key: SYSTEMML-1725
> URL: https://issues.apache.org/jira/browse/SYSTEMML-1725
> Project: SystemML
> Issue Type: Sub-task
> Components: Compiler, Runtime
> Reporter: Matthias Boehm
> Assignee: Matthias Boehm
> Fix For: SystemML 0.15
>
>
> There are a number of scripts such as Mlogreg, where we currently compile a
> sequence of row-wise and cell-wise templates because expressions consist of
> (1) various row aggregations, and (2) some additional cellwise operations
> with final full aggregate. This creates unnecessary intermediates and
> partially redundant computation. Hence, we should directly support full
> aggregations (at least sum) in rowwise templates as well.
