DLPack Tensor Exchange

When to Use

Use this skill when the user asks how attribute data moves in or out of ovstage as tensors: building DLTensors for a write, reading tensor data back, choosing CPU vs CUDA residency, synchronizing GPU producers/consumers with cuda_sync, writing through ovstage-allocated map buffers, passing sparse/gathered data (index_map / mask), or how long returned tensor data stays valid.

Inputs
