Description

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

Caused by: java.lang.IllegalArgumentException: No enum constant org.apache.sysml.hops.codegen.cplan.CNodeBinary.BinType.CBIND

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.
