             Summary: Performance issue codegen outer over ultra-sparse matrices
                 Key: SYSTEMML-1841
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1841
             Project: SystemML
          Issue Type: Bug
            Reporter: Matthias Boehm


Experiments with codegen outer operations over the Amazon Books review dataset (8,026,324
x 2,330,066, nnz=22,507,155, i.e., sparsity=10^(-6)) showed unnecessary overhead for this
ultra-sparse data set. This task aims to remove this overhead.
