FP8 Training (Floating Point 8-bit Training) Explained

FP8 (Floating Point 8-bit) is an 8-bit floating-point format used to reduce computational costs and memory usage in large model training while maintaining numerical precision comparable to FP16/BF16. Compared to traditional FP32 (32-bit floating point) and FP16 (16-bit floating point), FP8 further compresses data storage and computational demands, making large model training and inference more efficient.

1. Why FP8 Training?

As large language models (LLMs) grow in parameter size (e.g., DeepSeek-V3 with 6.7T parameters), training and inference face the following challenges:

  • Huge Memory Usage: FP32 requires 4 bytes to store a floating-point number, FP16 requires 2 bytes, while FP8 needs only 1 byte, significantly reducing GPU memory requirements, increasing batch size, and minimizing computational overflow.

  • Computational Performance Limitations: Matrix operations (e.g., MatMul and GEMM) dominate computational resources in large model training. FP8 allows computational units to process more data in parallel, increasing throughput.

  • Energy Optimization: Large model training consumes substantial power. FP8 reduces data transfer and computational demands, lowering overall power consumption and improving GPU efficiency.

2. FP8 Format vs. Traditional Floating-Point Formats

FP8 is not a single format but has two main variants:

  1. E4M3 (Exponent 4-bit, Mantissa 3-bit)

  • Suitable for activations (Activation)

  • 4-bit exponent, 3-bit mantissa, 1-bit sign

  • Smaller representation range but retains more dynamic changes

  1. E5M2 (Exponent 5-bit, Mantissa 2-bit)

  • Suitable for weights (Weights)

  • 5-bit exponent, 2-bit mantissa, 1-bit sign

  • Larger representation range but slightly lower precision

Comparison Example:

Format Exponent Bits Mantissa Bits Representation Range Applicable Scenario
FP32 8 23 ±10³⁸ High-precision deep learning
FP16 5 10 ±65,504 Conventional deep learning training/inference
BF16 8 7 ±3.9 × 10³⁸ More stable computation, lower precision than FP16
FP8 (E4M3) 4 3 ±448 Suitable for activations
FP8 (E5M2) 5 2 ±57344 Suitable for weights

3. Application of FP8 in DeepSeek-V3 Training

DeepSeek-V3 employs FP8 mixed-precision training to optimize model training efficiency, including:

  • FP8 training for weights and activations, reducing memory usage by over 50%;

  • FP8 computation for matrix multiplication (GEMM), enhancing computational throughput;

  • Mixed FP8+BF16 training, where:

    • Weights use E5M2

    • Activations use E4M3

    • Critical gradient calculations remain in BF16 for stability.

4. Challenges and Optimizations in FP8 Training

While FP8 training offers significant storage and computational optimizations, it also presents challenges:

  1. Numerical Precision Loss: With only 7-8 total storage bits (even fewer than FP16), FP8 may cause gradient overflow, affecting model convergence.

    • Solution: DeepSeek-V3 uses dynamic scaling to normalize FP8 values dynamically, ensuring stable precision.

  2. Computational Unit Support: Traditional GPUs (e.g., RTX 30 series) do not support FP8, requiring specialized hardware optimization.

    • Solution: FP8 training requires GPUs supporting NVIDIA Hopper or Ada Lovelace architectures, such as H100, A100, H800.

5. Future Prospects for FP8 Training

FP8 training has become a trend in large model optimization and is likely to be widely used in:

  • Ultra-large LLMs (e.g., DeepSeek-V3, Gemini, GPT-5)

  • Efficient model distillation (reducing training costs)

  • Low-power AI computing (improving energy efficiency)

  • High-concurrency AI tasks (reducing inference latency)

What is DualPipe Parallelism?

DualPipe Parallelism is a computation-communication overlap optimization strategy designed to enhance the efficiency of large-scale distributed training, particularly for MoE (Mixture of Experts) models and ultra-large LLMs (such as DeepSeek-V3). Its core idea is to overlap computation and communication, reducing the idle time of GPUs waiting for data transfer.

In traditional distributed training, especially in MoE structures:

  • Each GPU needs to share experts with multiple nodes, compute results, and then exchange data via All-to-All communication.

  • Since computation and communication are executed serially (communication starts only after computation is complete), communication delay becomes a bottleneck, affecting training efficiency.

DualPipe Parallelism uses dual pipeline technology to overlap computation and communication, significantly reducing the idle time of GPU resources and improving GPU utilization.

1. Why DualPipe Parallelism?

In DeepSeek-V3 training:

  • MoE Structure: Dynamic task allocation across nodes is required, with each GPU potentially handling multiple experts' computations.

  • Traditional All-to-All Communication: Easily leads to communication congestion, especially in training clusters with 1000+ GPUs, where communication time can exceed computation time.

  • DualPipe Parallelism: By overlapping computation and communication, training tasks do not need to wait for communication completion to start the next computation, effectively improving GPU computational efficiency.

2. How DualPipe Parallelism Works

DualPipe Parallelism enhances efficiency through three key optimization steps:

2.1 Computation-Communication Pipeline Overlap

  • While computing the current batch of data, simultaneously communicate the previous batch's data.

  • This way, computational tasks do not idle while waiting for data synchronization, and GPU computational resources are fully utilized.

📌 Illustration (Traditional vs. DualPipe):

Traditional Approach (Serial Computation and Communication)

Compute Batch1 → Transmit Batch1 → Compute Batch2 → Transmit Batch2 → ...

DualPipe Approach (Parallel Computation and Communication)

Compute Batch1 → Compute Batch2
Transmit Batch1 → Transmit Batch2

DualPipe allows simultaneous computation and communication, avoiding GPU idling.

2.2 Dynamic Expert Routing

  • In MoE structures, some experts may be "hotter" than others (i.e., used by more tokens), leading to uneven GPU computational load.

  • DualPipe employs a dynamic expert routing mechanism to pre-schedule the optimal expert combination during the computation phase, reducing communication pressure.

2.3 Parallel Gradient Synchronization

  • During training, gradients need to be synchronized across different GPUs.

  • Traditional Method: Synchronize all gradients after computing them (serial).

  • DualPipe: Synchronize the previous batch's gradients while computing the next batch's gradients, reducing gradient synchronization wait time.

3. Advantages of DualPipe Parallelism

Reduced Communication Wait

  • Computation and communication overlap, reducing 80%+ communication wait time, enhancing GPU computational efficiency.

Improved GPU Resource Utilization

  • During training, GPUs no longer idle while waiting for data transfer, increasing overall throughput by 20%-30%.

Optimized MoE Computation

  • Specifically designed for Mixture of Experts (MoE), ensuring more balanced expert allocation and reducing the load on hot GPUs.

Reduced Communication Bottlenecks in Distributed Training

  • In training clusters with 2048+ GPUs, reduces 30%+ communication overhead, effectively boosting large-scale LLM training efficiency.

4. DualPipe Parallelism vs. Other Parallel Methods

Parallel Method Computation-Communication Overlap Suitable for MoE Suitable for Large-Scale Training Communication Optimization
Data Parallelism (DP) ❌ No ✅ Yes ✅ Yes ❌ Requires gradient synchronization
Tensor Parallelism (TP) ❌ No ✅ Yes ✅ Yes ❌ Requires extensive communication
Expert Parallelism (EP) ❌ No ✅ Yes ✅ Yes ❌ Requires expert load balancing
DualPipe Parallelism ✅ Yes ✅ Yes ✅ Yes ✅ Efficient All-to-All communication

📌 Summary:

  • Data Parallelism (DP) and Tensor Parallelism (TP) are suitable for conventional Transformer structures but suffer from high communication overhead in MoE structures, limiting training efficiency.

  • DualPipe Parallelism is a specialized computational optimization for MoE and ultra-large LLMs, maximizing computation-communication overlap and overall training efficiency.

5. Application of DualPipe Parallelism in DeepSeek-V3 Training

DeepSeek-V3's training combines DualPipe Parallelism + FP8 mixed-precision training:

  • DualPipe computation-communication overlap optimizes expert load balancing in MoE computations;

  • FP8 low-precision training reduces memory usage and enhances computational throughput;

  • InfiniBand + NVLink with DualPipe parallelism improves cross-node communication efficiency, enabling training on 2048+ GPUs.
