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

             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.
