## Description ## This is the branch to add the zero sharding (especially partitioning gradient). The changes can be divided into three part: 1. in C++, I add an operation called reduce operation. It will do nothing in forward but reduce gradient on backward. 2. Then open an API called backward option to delete the output of certain graph. ## Checklist ## ### Essentials ### - [ ] PR's title starts with a category (e.g. [BUGFIX], [MODEL], [TUTORIAL], [FEATURE], [DOC], etc) - [ ] Changes are complete (i.e. I finished coding on this PR) - [ ] All changes have test coverage - [ ] Code is well-documented ### Changes ### - [ ] Feature1, tests, (and when applicable, API doc) - [ ] Feature2, tests, (and when applicable, API doc) ## Comments ## - If this change is a backward incompatible change, why must this change be made. - Interesting edge cases to note here -- This is an automated message from the Apache Git Service.
