Summary: Improve the performance of binary cell-wise operations
Key: SYSTEMML-824
URL: https://issues.apache.org/jira/browse/SYSTEMML-824
Project: SystemML
Issue Type: Task
Reporter: Niketan Pansare
The cellwise (matrix-matrix as well as matrix-scalar) operations take
significant amount of time while training Lenet. Here are few ways to improve
the performance of cell-wise operations:
1. Inject in-place updates [1] (saving on zero-ing out the matrix).
2. Fused cell-wise operations (as an example, recently added axpy operations).
3. Parallelize cellwise operations (initial investigation need to be conducted
before proceeding in this direction especially in sparse case:
https://github.com/apache/incubator-systemml/blob/master/src/main/java/org/apache/sysml/runtime/matrix/data/LibMatrixBincell.java#L274).
