Summary: Improve CLA robustness for incompressible inputs
Key: SYSTEMML-1916
URL: https://issues.apache.org/jira/browse/SYSTEMML-1916
Project: SystemML
Issue Type: Sub-task
Reporter: Matthias Boehm
This task aims to add a very check pre-filtering step to check for completely
incompressible blocks, in which case we should immediately return the original
block instead of going through the elaborate compression process and ending up
with a single column group in UC format.
