             Summary: Large GC overhead for scripts w/ row-wise generated 
                 Key: SYSTEMML-1836
             Project: SystemML
          Issue Type: Bug
            Reporter: Matthias Boehm

This task aims to improve the unnecessary large garbage collection overhead for 
scripts with many row-wise fused operators. For example, Kmeans and Mlogreg 
over 10M x 10 inputs show GC overheads of 102s and 37s, respectively.
