[GitHub] [systemds] phaniarnab opened a new pull request, #1783: [SYSTEMDS-3497] Refactor to add LOP rewrite step in compilation
phaniarnab opened a new pull request, #1783:
URL: https://github.com/apache/systemds/pull/1783
This patch adds a new step in the compilation (and recompilation) steps to rewrite Lop DAGs (single and multi-statement block). Current rewrite passes include adding prefetch, broadcast and checkpoint nodes. This refactoring allows us easily add new rewrite rules and separate the Lop rewrites from operator ordering.
