-----------------------------------
Assignee: Janardhan
> Candidate exploration w/ unknowns
> ---------------------------------
>
> Key: SYSTEMML-2066
> URL: https://issues.apache.org/jira/browse/SYSTEMML-2066
> Project: SystemML
> Issue Type: Sub-task
> Reporter: Matthias Boehm
> Assignee: Janardhan
> Priority: Major
>
> Various JMLC applications (for low-latency scoring) would also benefit from
> code generation. However, by default, JMLC disables dynamic recompilation in
> order to avoid unnecessary compilation overhead. Since both candidate
> exploration and candidate selection rely on sizes for validity constraints
> and cost comparisons, the unknowns during initial compilation can lead to
> invalid plans (e.g., selecting a vector side input as main input).
> This task aims to introduce a new candidate exploration mode that only
> considers safe candidates such as unary operations, or binary matrix-scalars
> operations, which do not depend on size information.
