Details
Do not mention proprietary info or link to internal work items in this PR.
Work item: "Internal", or link to GitHub issue (if applicable).
What were the changes?
Initializing all ranks to the same value to avoid failure of UT AllReduce for FP8 type
Why were the changes made?
The UT was failed before for FP8 types.
How was the outcome achieved?
Due to floating-point math not being commutative, the ordering in which ranks are added will matter, we need to initialize all the ranks to the same value to avoid it.
