----------------------------------------
Summary: Improve Left-Indexing Performance with (Nested) Parfor
Loops
Key: SYSTEMML-633
URL: https://issues.apache.org/jira/browse/SYSTEMML-633
Project: SystemML
Issue Type: Improvement
Reporter: Mike Dusenberry
In the experimental deep learning DML library I've been building
([https://github.com/dusenberrymw/systemml-nn|https://github.com/dusenberrymw/systemml-nn]),
I've experienced severe bottlenecks due to *left-indexing* in parfor loops.
Here, I will highlight a few particular instances, but the same issue is shared
across many areas of the library, particularly in the convolution and max
pooling layers.
