#sdy Insert
sdy.all_reduce
ops in-sdy-insert-explicit-reshards
pass.If an op has a sharded reduction factor (e.g., contracting dim of dot) after reshards are inserted, we should insert a
sdy.all_reduce
with the axes that shard all reduction factors.In the future, when we have support for unreduced axes in TensorShardingAttr, we can have this pass insert a reshard from unreduced axes to replicated axes, and insert the all-reduce later on.
