Don't we need more checks, here? What happens if we call
annotate_custom_sharding
beforemark_sharding
? Is this supposed to work?Uh oh!

Yes, it should work - but the intended behavior here could be ambiguous. At that point,
mark_sharding
would similarly just be adding a custom sharding op, since the provided tensor has an IR custom sharding value/node - not a device data node. If we want themark_sharding
following it to identify the parent Device Data node IR and invoke a sharded data transfer - that is something we can discuss/evaluate.The problem is that, in most cases,
mark_sharding
is intended to be used as expected for any Device Data node, since it'll have an async runtime buffer alloc over the sharded segments only. In this case, each device would have its own sharded data, and that'll be reflected on the HLO inputs. But what if users want to explicitly have an XLA IR custom sharding over a device data node - that including a replicated tensor as an input to the graph, or simply additional annotations that relies on the XLA compiler to add the optimal CC ops to accommodate the hint.
