             Summary: Perftest stratstats w/ codegen getting stuck in optimization
                 Key: SYSTEMML-2021
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-2021
             Project: SystemML
          Issue Type: Bug
            Reporter: Matthias Boehm


On stratstats 10K, the codegen optimizer gets stuck during plan enumeration of a DAG partition
with 274,877,906,944 plans. During initial compilation, the same partition was processed in
2.8s as most candidate plans have been successfully pruned by cost or structure.
