Summary: Fix GPU tests for single precision
Key: SYSTEMML-1975
URL: https://issues.apache.org/jira/browse/SYSTEMML-1975
Project: SystemML
Issue Type: Bug
Reporter: Niketan Pansare
The current GPU tests for single precision compares the results of double
precision operation on CPU with single precision operation on GPU. So, it is
difficult to compare the results. When we support single precision on CPU, we
can rework the GPU tests to fix the following tests:
