tf.raw_ops.CollectiveAllToAllV2

Mutually exchanges multiple tensors of identical type and shape.
tf.raw_ops.CollectiveAllToAllV2(
input,
group_size,
group_key,
instance_key,
ordering_token,
communication_hint='auto',
timeout_seconds=0,
is_stateless=False,
name=None
)
is_stateless means each op does not need control dependencies to other collective ops. In this case, keys that are unique at runtime (e.g. instance_key) should be used to distinguish collective groups.
Args |
|---|
input | A Tensor. Must be one of the following types: bfloat16, float32, half, float64, int32, int64. |
group_size | A Tensor of type int32. |
group_key | A Tensor of type int32. |
instance_key | A Tensor of type int32. |
ordering_token | A list of Tensor objects with type resource. |
communication_hint | An optional string. Defaults to "auto". |
timeout_seconds | An optional float. Defaults to 0. |
is_stateless | An optional bool. Defaults to False. |
name | A name for the operation (optional). |
Returns |
|---|
A Tensor. Has the same type as input. |
