Symbolic Representation of Layer-wise Parallelism
In layer-wise parallelism, the computation for a given block, denoted as , is represented by . The forward pass is symbolized by an upward arrow (), and the backward pass by a downward arrow (). For instance, the forward and backward computations for Block 1 would be shown as () and (), while for Block 2 they would be () and ().

Symbolic Representation of Layer-wise Parallelism
A large neural network decoder, consisting of 12 sequential processing blocks, is distributed across 12 separate workers, with each worker assigned exactly one block. For a single input, the computation proceeds sequentially through the workers from 1 to 12 during the forward pass, and then in reverse from 12 to 1 during the backward pass. What is the primary factor limiting the overall computational efficiency of this specific arrangement?
A 3-block neural network decoder is distributed across 3 workers using layer-wise parallelism, with each worker responsible for one block (Worker 1 has Block 1, Worker 2 has Block 2, and Worker 3 has Block 3). For a single training iteration, arrange the following computational events in the correct chronological order.

A computational process involving two sequential blocks, Block 1 (B₁) and Block 2 (B₂), is represented by the following sequence of operations: B₁ ↑, B₂ ↑, B₂ ↓, B₁ ↓. What does this sequence describe?
A neural network model is divided into three computational blocks (Block 1, Block 2, and Block 3) for layer-wise parallelism. Arrange the symbolic representations of the computations for a single, complete forward and backward pass in the correct chronological order.
