With the explanation > The main problem for reduction by reference is that, prior to this PR, we > were shuffling (from remote lanes within the same warp or across different > warps within the block) pointers/references to the private reduction values > rather than the private reduction values themselves. this PR makes sense to me. Would be good if it could be added to the summary.
