----------------------------------------
Summary: Shuffle-free spark reblock of aligned binary block
matrices
Key: SYSTEMML-1920
URL: https://issues.apache.org/jira/browse/SYSTEMML-1920
Project: SystemML
Issue Type: Task
Reporter: Matthias Boehm
Given a scenario of, for instance, a reblock of binary block matrices from 16K
to 1K, we should provide a shuffle-free reblock to exploit such aligned
blocksizes, where it's guaranteed that blocks can be created locally without
overlap.
