convolution operations
Matthias Boehm created SYSTEMML-1381:
----------------------------------------
Summary: Negative memory estimates of convolution operations
Key: SYSTEMML-1381
URL: https://issues.apache.org/jira/browse/SYSTEMML-1381
Project: SystemML
Issue Type: Bug
Reporter: Matthias Boehm
Recent experiments with convolution operations in a parfor context, showed several issues related to the memory estimates of these operations:
