Summary: Improve efficiency sparse-unsafe cellwise operations
Key: SYSTEMML-1591
URL: https://issues.apache.org/jira/browse/SYSTEMML-1591
Project: SystemML
Issue Type: Sub-task
Reporter: Matthias Boehm
For sparse-unsafe cellwise operations, we currently iterate over all cells and
use binary search to access the individual values. This is unnecessarily
inefficient to should be reworked in favor of a sequential scan with gap
handling, which would also allow us to consolidate the different code paths for
sparse-safe and -unsafe operations.
