  r"""Outputs a tensor containing the reduction across all input tensors.

  Outputs a tensor containing the reduction across all input tensors passed to ops
  within the same `shared_name.
  
  The graph should be constructed so if one op runs with shared_name value `c`,
  then `num_devices` ops will run with shared_name value `c`.  Failure to do so
  will cause the graph execution to fail to complete.
  
  input: the input to the reduction
  data: the value of the reduction across all `num_devices` devices.
  reduction: the reduction operation to perform.
  num_devices: The number of devices participating in this reduction.
  shared_name: Identifier that shared between ops of the same reduction.

  Args:
    input: A `Tensor`. Must be one of the following types: `half`, `float32`, `float64`, `int32`, `int64`.
    reduction: A `string` from: `"min", "max", "prod", "sum"`.
    num_devices: An `int`.
    shared_name: A `string`.
