[jira] [Created] (SYSTEMML-1832) Redundant checkpoint instructions
before loops
Matthias Boehm created SYSTEMML-1832:
----------------------------------------
Summary: Redundant checkpoint instructions before loops
Key: SYSTEMML-1832
URL: https://issues.apache.org/jira/browse/SYSTEMML-1832
Project: SystemML
Issue Type: Bug
Reporter: Matthias Boehm
Static rewrites include HOP DAG and statement block rewrites. We apply these rewrites multiple times during compilation (e.g., rewrites followed by multiple passes of IPA). Some of the static rewrites such as {{RewriteInjectSparkLoopCheckpointing}} assume that they are called once for a program. Applying them multiple times leads to redundant statement blocks with redundant checkpoint instructions. Accordingly, IPA should explicitly disable such rewrites.
