Parallelism Concepts

See: 🤗 Model Parallelism for additional details

Single GPU

Figure 1: SLOW !! model size limited by GPU memory

Data Parallel (DP)

• The simplest and most common parallelism technique

• Workers maintain identical copies of the complete model and work on a subset of the data

  • Multiple copies of the same setup
    • each copy gets fed unique data
    • all copies compute gradients w.r.t local model
    • everyone syncs up before updating weights

• The processing is done in parallel and all setups are synchronized at the end of each training step.

Figure 2: Data Parallel Training

Tensor Parallel (TP)

• Each tensor is split up into multiple chunks
• So, instead of having the whole tensor reside on a single GPU, each shard of the tensor resides on its designated GPU
  • During processing each shard gets processed separately and in parallel on different GPUs and the results are synced at the end of the step.
  • This is what one may call horizontal parallelism, as the splitting happens on horizontal level.

Figure 3: Tensor Parallel Training

Pipeline Parallel (PP)

• Model is split up vertically (layer-level) across multiple GPUs, so that only one or several layers of the model are places on a single GPU
  • Each GPU processes in parallel different stages of the pipeline and working on a small chunk of the batch.

Figure 4: Pipeline Parallelism

ZeRO

Figure 5: DeepSpeed + ZeRO

• Shards tensors (~ similar to TP), except:

  • whole tensor gets reconstructed as needed

  • Doesn’t require model modifications !!

• Depending on the ZeRO stage (1, 2, 3), we can offload:

  1. Stage 1: optimizer states

  2. Stage 2: gradients + opt. states

  3. Stage 3: model params + grads + opt. states

  with increasing ZeRO stage, we are able to free up increasing amounts of GPU memory

• ZeRO Data Parallel

  • ZeRO powered data parallelism is shown below

• It also supports various offloading techniques to compensate for limited GPU memory.

• 🔗 See also:

  • ZeRO — DeepSpeed 0.14.5 documentation
  • ZeRO-Offload
  • ZeRO & DeepSpeed: New system optimizations enable training models with over 100 billion parameters - Microsoft Research

FSDP

• Instead of maintaining per-GPU copy of {params, grads, opt_states}, FSDP shards (distributes) these across data-parallel workers
  • can optionally offload the sharded model params to CPU

FSDP Workflow. Source

  • Introducing PyTorch Fully Sharded Data Parallel (FSDP) API | PyTorch

Data Parallelism

Data Parallel Training

• Relatively simple to get up and running (minor modifications to code)
• saforem2/ezpz
• PyTorch – DDP
• DeepSpeed

Figure 6: Data Parallelism

Also see: 🎬 “Parallel Training Techniques”_

Deal with Data

• At each training step, we want to ensure that each worker receives unique data

• This can be done in one of two ways:

  1. Manually partition data (ahead of time) and assign different sections to different workers
     1. Each worker can only see their local portion of the data
  2. From each worker, randomly select a mini-batch
     1. Each worker can see the full dataset
  ⚠️ Warning

  Don’t forget your seed!

  When randomly selecting, it is important that each worker uses different seeds to ensure they receive unique data

Broadcast Initial State

• At the start of training (or when loading from a checkpoint), we want all of our workers to be initialized consistently

  • Broadcast the model and optimizer states from rank() == 0 worker

  flowchart TD
    0["GPU0"] --> 1["GPU 1"]
    0 --> 2["GPU 2"]
    0 -->|Model + Optimizer State| 3["GPU 3"]
    0 --> ...
    0 --> N["GPU N"]

Best Practices

🤝 Keeping things in Sync

Computation stalls during communication !!

Keeping the communication to computation ratio small is important for effective scaling.

• Use parallel IO whenever possible
  • Feed each rank from different files
  • Use MPI IO to have each rank read its own batch from a file
  • Use several ranks to read data, MPI to scatter to remaining ranks
    • Most practical in big at-scale training
• Take advantage of data storage
  • Use striping on lustre
  • Use the right optimizations for Aurora, Polaris, etc.
• Preload data when possible
  • Offloading to a GPU frees CPU cycles for loading the next batch of data
    • minimize IO latency this way

Why Distributed Training?

• Splitting data across workers \longrightarrow larger batch size³
  • [micro_batch_size = 1] \times [N GPUs] \rightarrow [global_batch_size = N]
• Smooth loss landscape
• Improved gradient estimators
• Less iterations needed for same number of epochs
  • May need to train for more epochs if another change is not made
  • e.g. scaling learning rate
• See Large Batch Training of Convolutional Networks

Deciding on a Parallelism Strategy

Single GPU

• Model fits onto a single GPU:
  • Normal use
• Model DOES NOT fit on a single GPU:
  • ZeRO + Offload CPU (or, optionally, NVMe)
• Largest layer DOES NOT fit on a single GPU:
  • ZeRO + Enable Memory Centric Tiling (MCT)
    • MCT Allows running of arbitrarily large layers by automatically splitting them and executing them sequentially.

Single Node / Multi-GPU

• Model fits onto a single GPU

  • DDP
  • ZeRO

• Model DOES NOT fit onto a single GPU[^connectivity]

  1. Pipeline Parallelism (PP)
  2. ZeRO
  3. Tensor Parallelism (TP)

• With sufficiently fast connectivity between nodes, these three strategies should be comparable.

  Otherwise, PP > ZeRO \simeq TP.

Multi-Node / Multi-GPU

• When you have fast inter-node connectivity:

  • ZeRO (virtually NO modifications)
  • PP + ZeRO + TP + DP (less communication, at the cost of MAJOR modifications)

    • when you have slow inter-node connectivity and still low on GPU memory:

      DP + PP + TP + ZeRO-1

  • NOTE: TP is almost always used within a single node, e.g. TP <= GPUS_PER_NODE

Tensor (/ Model) Parallel Training: Example

\begin{align*} y &= \sum_{i} w_{i} * x_{i} \\ &= w_0 * x_0 + w_1 * x_1 + w_2 * x_2 \end{align*}

1. Compute y_{0} = w_{0} * x_{0} and send to \longrightarrow GPU1
2. Compute y_{1} = y_{0} + w_{1} * x_{1} and send to \longrightarrow GPU2
3. Compute y = y_{1} + w_{2} * x_{2} ✅

  subgraph X0["GPU0"]

  end

    b["w1"]

  subgraph X2["GPU2"]
    direction LR
    c["w2"]
  end
  X1 & X0 <--> X2
  X0 <--> X1
  x["x0, x1, x2"] --> X0

Model Parallel Training

• Split up network over multiple workers
  • Each receives disjoint subset
  • All communication associated with subsets are distributed
• Communication whenever dataflow between two subsets
• Typically more complicated to implement than data parallel training
• Suitable when the model is too large to fit onto a single device (CPU / GPU)
• argonne-lcf/Megatron-DeepSpeed
• 🤗 huggingface/nanotron

Figure 7

Tensor (Model) Parallelism⁴

• In Tensor Paralleism each GPU processes only a slice of a tensor and only aggregates the full tensor for operations that require the whole thing.

  • The main building block of any transformer is a fully connected nn.Linear followed by a nonlinear activation GeLU.

    • Y = GeLU(XA), where X and Y are the input and output vectors, and A is the weight matrix.

  • If we look at the computation in matrix form, it’s easy to see how the matrix multiplication can be split between multiple GPUs:

3D Parallelism

• DP + TP + PP (3D) Parallelism

Figure 9: Figure taken from 3D parallelism: Scaling to trillion-parameter models

Collective Communication

Typically, we assign 1 rank to each GPU (or accelerator), i.e. rank \in [0, 1, ..., WORLD_SIZE-1].

AllReduce

• Perform reductions on data (e.g. sum, min, max) across ranks, send result back to everyone

Figure 10: All-Reduce operation: each rank receives the reduction of input values across ranks.

Reduce

• Perform a reduction on data across ranks, send to individual

Figure 11: Reduce operation: one rank receives the reduction of input values across ranks

Broadcast

• broadcast (send) a tensor x from one rank to all ranks

Figure 12

AllGather

• Gathers tensors from the whole group in a list.

Figure 13

Scatter

• Scatters a list of tensors to the whole group

Figure 14

Collective Operations

⌛ Timeouts

• Collective operations have to be called for each rank to form a complete collective operation.
  • Failure to do so will result in other ranks waiting indefinitely

parallelism, lr_schedule, ...}

3. Supervised Fine-Tuning

   • Instruction Tuning
   • Alignment

4. Deploy (+ monitor, re-evaluate, etc.)
