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

             Summary: Performance permutation matrix multiply
                 Key: SYSTEMML-2015
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-2015
             Project: SystemML
          Issue Type: Task
            Reporter: Matthias Boehm


The SystemML compiler usually tries to eliminate unnecessary permutation matrix multiplications.
However, whenever this is not possible, there are a couple of unnecessary overheads related
to diag, removeEmpty that this task aims to address.
