----------------------------------------

             Summary: Matrix multiplication chain opt not applied
                 Key: SYSTEMML-1641
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1641
             Project: SystemML
          Issue Type: Bug
    Affects Versions: SystemML 0.14
            Reporter: Matthias Boehm


A recent change in SystemML 0.14 that simplified the hop visit status introduced a bug in
our matrix multiplication chain optimization rewrites, which effectively disabled this rewrite
altogether.
