oneflow.comm.scatter(tensor, scatter_list=None, src=0)

Scatters a list of tensors to all processes in a group.

Each process will receive exactly one tensor and store its data in the tensor argument.

  • tensor (Tensor) – Output tensor.

  • scatter_list (list[Tensor]) – List of tensors to scatter (default is None, must be specified on the source rank)

  • src (int) – Source rank (default is 0)
