             Summary: Perftest Mlogreg 10M x 1K, icpt 1 codegen failing w/ unsupported cbind in cell
                 Key: SYSTEMML-2028
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-2028
             Project: SystemML
          Issue Type: Bug
            Reporter: Matthias Boehm


The perftest scenario Mlogreg icpt 1 for 10M x 1K is failing due to unsupported cbind in cell templates.

The root cause is that row memo table entries are converted to cell entries due to violated blocksize constaints, this is however not valid for cbind and similar operations that are not supported in cell templates.
