hello, I'm looking into how to use subgroup shuffle to get maximum performance for matrix multiply. And I searched online and couldn't find an example of how to use the "shuffle" feature to share data within work-items in a sub-group. Attached article gives some instructions but there is no full code. Is there any read-to-go code to demostrate how to use "shuffle"? Thanks in advance!
