             Summary: Performance sparse relu_backward operations
                 Key: SYSTEMML-2129
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-2129
             Project: SystemML
          Issue Type: Sub-task
            Reporter: Matthias Boehm


This task aims to fix performance issues in sparse relu_backward operations, including dedicated
implementations for sparse-dense combinations, sparse output allocation (to avoid dense allocation
and conversion to sparse), and thread-local nnz maintenance.
