---
Mixed precision training uses lower precision data types to reduce memory usage and increase training speed while maintaining model quality. Axolotl supports several mixed precision formats:
- **FP16** - Half precision 16-bit (Pascal generation+)
- **BF16** - Brain Float 16-bit (Ampere generation+)
- **FP8** - 8-bit floating point (Hopper generation+)
## FP16 Mixed Precision {#sec-fp16}
### Overview {#sec-fp16-overview}
FP16 is the traditional half-precision format, supported on older GPUs but can be less numerically stable than BF16.
### Configuration {#sec-fp16-config}
```{.yaml}
fp16: true
```
### FP16 Considerations {#sec-fp16-considerations}
- May require gradient scaling to prevent underflow
- Less numerically stable than BF16
- Can cause training instability with some model architectures
- Consider using BF16 if your hardware supports it
## BF16 Mixed Precision {#sec-bf16}
### Overview {#sec-bf16-overview}
BF16 (Brain Float 16) offers better numerical stability than FP16 and is the recommended mixed precision format for modern GPUs. It provides the same dynamic range as FP32 while using half the memory.
### Configuration {#sec-bf16-config}
```{.yaml}
# Automatic BF16 detection (recommended)
bf16: auto
# Or explicitly enable
bf16: true
# For evaluation with BF16
bf16: full # Equivalent to bf16_full_eval in the HF trainer
```
## FP8 Mixed Precision {#sec-fp8}
::: {.callout-note}
FP8 support is experimental and requires compatible hardware (H100, H200) and recent PyTorch versions with TorchAO.
:::
### What is FP8? {#sec-fp8-overview}
FP8 (8-bit floating point) can provide significant time savings compared to FP16/BF16 while maintaining training stability. Axolotl's implementation uses PyTorch's TorchAO library with "tensorwise" scaling strategy.
### Requirements {#sec-fp8-software}
- Hopper+ GPUs (H100/H200)
- PyTorch 2.7+ (+ compatible TorchAO version)
- CUDA 12.4+
### Configuration {#sec-fp8-config}
Add to your YAML config:
```{.yaml}
# Enable FP8 mixed precision
fp8: true
# Optional: Enable FP8 for FSDP all-gather operations
fp8_enable_fsdp_float8_all_gather: true
# Enable torch.compile (almost always necessary for FP8 speedups)
torch_compile: true
```
::: {.callout-important}
**torch.compile is critical for FP8 performance**
FP8 training requires `torch_compile: true` to see meaningful speedups. Without compilation, FP8 may actually be slower and use more memory than FP16/BF16.
:::
### Advanced FP8 Configs {#sec-fp8-advanced}
For [FSDP](multi-gpu.qmd#sec-fsdp) (Fully Sharded Data Parallel) training:
```{.yaml}
fp8: true
fp8_enable_fsdp_float8_all_gather: true
torch_compile: true
# FSDP configuration
fsdp_version: 2
fsdp_config:
offload_params: false
cpu_ram_efficient_loading: true
auto_wrap_policy: TRANSFORMER_BASED_WRAP
transformer_layer_cls_to_wrap: LlamaDecoderLayer
state_dict_type: FULL_STATE_DICT
reshard_after_forward: true
```
## Best Practices {#sec-best-practices}
### Choosing Precision Format {#sec-choosing-format}
- **Start with automatic detection**: `bf16: auto`
- **For Hopper+ (H100/H200)**: Try FP8 + torch.compile for maximum speed
- **For Ampere (A100/RTX 30/40)**: Use BF16
- **For older Pascal/Turing GPUs**: Use FP16 with caution
- **For very old or unsupported GPUs**: Use FP32
### Validation and Testing {#sec-validation}
Always validate your mixed precision setup:
- **Start with a small dataset** to verify stability
- **Monitor loss curves** for irregularities
- **Compare with FP32 baseline** when possible
- **Test evaluation metrics** match expectations
### FP8 Particulars {#sec-fp8-details}
- Use cases
- Single GPU training
- Multi GPU training with FSDP2 or Deepspeed
- Speedups
- Please refer to the [TorchAO FP8 training benchmarks](https://github.com/pytorch/ao/tree/main/torchao/float8#rowwise-scaling) for expected matmul speedups for different (M, K, N) settings
- Concrete number for LLaMA 3 8B training can be found [here](https://github.com/pytorch/ao/tree/main/torchao/float8#training-benchmarks)
- Known issues:
- FP8 + DDP + `torch.compile` (causes [error](https://gist.github.com/djsaunde/0c1664c32e44a64d31b5e01b4aafe5c4))
- FP8 + FSDP2 + `torch.compile` + FSDP2 activation checkpointing tends to be _slower_ than the BF16 equivalent training
- Flash Attention 2 does not play nicely with `torch.compile`
See `examples/llama-3/3b-fp8-fsdp2.yaml` for an optimized example config. Enabling FP8 mixed precision + FP8 all-gather training results in ~10% faster iterations per second vs. BF16 for a relatively small (3B param) model

title: "N-D Parallelism (Beta)"
---
Axolotl enables training models at scale by composing different parallelism techniques. This is essential when:
- A model's weights are too large to fit on a single GPU's memory.
- A model's activations, especially with very long contexts, are too large for a single GPU.
- You want to accelerate training by using multiple GPUs or nodes.
or combinations of the above!
## Core Concepts
Parallelism strategies can be combined. The key is understanding how each one divides the workload. PyTorch's `DeviceMesh` is the modern way to manage these combinations, creating a logical grid of your GPUs and assigning different parallel strategies to different dimensions of the grid.
### Data Parallelism {#sec-dp}
Data Parallelism focuses on splitting the global data batch across GPUs.
- Distributed Data Parallel (DDP): The classic approach. The full model is replicated on every GPU. Each GPU processes a different slice of the data batch. Gradients are then averaged across all GPUs after the backward pass to keep the models synchronized. This can substantially improve data throughput compared to single-device training, but requires that each GPU is able to hold the entire model, its gradients, and optimizer states.
- [Fully Sharded Data Parallel (FSDP)](multi-gpu.qmd#fully-sharded-data-parallel-(fsdp)): A highly memory-efficient form of data parallelism (inspired by DeepSpeed's ZeRO). Instead of replicating the model, FSDP shards the model's *parameters, gradients, and optimizer states* across the GPUs in the data-parallel group. During computation, each GPU receives the specific parameters it needs via an `all_gather` operation just before they are used, and they can be discarded immediately after (`reshard-after-forward`).
- FSDP maps to ZeRO stages:
- ZeRO-2 (`reshard_after_forward=False`): Shards gradients and optimizer states. Model weights are replicated on each GPU.
- ZeRO-3 (`reshard_after_forward=True`): Shards gradients, optimizer states, AND model parameters. This provides the most memory savings at the cost of more communication (re-gathering parameters for both forward and backward passes).
### [Experimental] Tensor Parallelism (TP) {#sec-tp}
Also known as "horizontal model parallelism," as described in the [Megatron-LM paper](https://arxiv.org/pdf/1909.08053.pdf). Instead of splitting the batch, TP splits the model's layers themselves across GPUs.
- How it works: For a linear layer `Y = XA`, the weight matrix `A` is split column-wise (`A = [A_1, A_2]`). The computation becomes `Y_1 = XA_1` and `Y_2 = XA_2`, which can happen in parallel on different GPUs. The final output `Y` is simply the concatenation of `Y_1` and `Y_2`. Check [this comment](https://github.com/huggingface/transformers/issues/10321#issuecomment-783543530) for more detailed info.
- Requirement: TP involves frequent, small communications within a forward/backward pass. It requires a very fast interconnect between GPUs (e.g., NVLink) and is typically not recommended across different nodes.
### Context Parallelism (CP) {#sec-cp}
Context Parallelism, also called [Sequence Parallelism](sequence_parallelism.qmd), addresses the memory bottleneck from long sequences. The input sequence itself is split along the sequence length dimension and distributed across GPUs.
- How it works: If you have a sequence of 8192 tokens and a `context_parallel_size` of 4, each GPU will only handle a chunk of 2048 tokens.
- The Challenge: Attention is not local; every token needs to "attend to" every other token. Splitting the sequence breaks this.
- The Solution (`ring-flash-attention`): An efficient communication protocol is used. To compute attention for its local sequence chunk, each GPU passes its Key-Value (KV) cache to its neighbor in a "ring." After `N-1` steps, every GPU has seen the KV-cache from all other GPUs, allowing it to compute the correct attention values for its chunk. This is implemented using the highly optimized `flash-attention` kernel at each step.
### Hybrid Sharding Data Parallel (HSDP) {#sec-hsdp}
HSDP is a 2D strategy that intelligently combines FSDP and DDP, typically for multi-node training.
- Intra-Node (within a machine): Use FSDP. This is efficient because GPUs on the same node have fast interconnects (NVLink), making the `all_gather` operations for sharded parameters fast.
- Inter-Node (across machines): Use DDP. The gradient synchronization between nodes is less frequent than FSDP's parameter gathering, making it a better fit for the slower node-to-node network (e.g., Ethernet/Infiniband).
- Example: With 2 nodes of 8 GPUs each (16 total), you could have `dp_shard_size=8` (FSDP within each node) and `dp_replicate_size=2` (DDP across the two nodes).
## Usage
```yaml
# FSDP config. See https://docs.axolotl.ai/docs/multi-gpu.html#sec-fsdp
fsdp_version: 2
fsdp_config:

## Examples
::: {.callout-tip}
See our example configs [here](https://github.com/axolotl-ai-cloud/axolotl/tree/main/examples/distributed-parallel).
:::
1. HSDP on 2 nodes with 4 GPUs each (8 GPUs total):
- You want FSDP within each node and DDP across nodes.
- Set `dp_shard_size: 4` and `dp_replicate_size: 2`.
2. FSDP + TP on a single 8-GPU node:
- You want to split the model across 4 GPUs using FSDP, and further split each layer across 2 GPUs with TP.
- Set `dp_shard_size: 4` and `tensor_parallel_size: 2`.
3. FSDP + CP on a single 8-GPU node for long context:
- You want to shard the model across all 8 GPUs and also split the sequence length across all 8 GPUs.
- Set `dp_shard_size: 8` and `context_parallel_size: 8`. Note: this means the data parallel group and context parallel group are the same. A more common setup might be to shard across a smaller group.
## Support Matrix
This matrix describes how different parallelism methods can be combined in Axolotl.
| Combination | `dp_replicate_size` | `dp_shard_size` | `tp_size` | `cp_size` | Status & Notes |
| --- | :---: | :---: |:---:|:---:|---|
| **FSDP** (ZeRO-3) | 1 | >1 | 1 | 1 | ✅ Fully supported. Shards model across all GPUs. |
| **HSDP** | >1 | >1 | 1 | 1 | ✅ Fully supported. FSDP intra-node, DDP inter-node. |
| **FSDP + TP** | 1 | >1 | >1 | 1 | ✅ **2D Parallelism**. Shards the model across a `dp_shard` group, and TP-splits layers within the `tp` group. |
| **HSDP + TP** | >1 | >1 | >1 | 1 | ✅ **3D Parallelism**. A powerful but complex combination. |
| **FSDP + CP** | 1 | >1 | 1 | >1 | ✅ **2D Parallelism**. Combines FSDP with context parallelism. |
| **FSDP + TP + CP**| 1 | >1 | >1| >1| ✅ **3D Parallelism**. Another advanced combination. |
| DDP + TP/CP | >1 | 1 | >1 | >1 | ❌ **Not Supported**. The `ParallelismConfig` explicitly prevents this, as composing pure DDP with TP or CP is currently not supported. You should use FSDP + TP/CP instead (`dp_shard_size > 1`). |
| Just TP / CP | 1 | 1 | >1 | >1 | ✅ Supported. Useful for inference or when the model fits on one GPU but context is too long. |
- `tp_size` refers to `tensor_parallel_size`
- `cp_size` refers to `context_parallel_size`

## Effect on Batch Size
When using sequence parallelism, your effective global batch size is **divided** by the `context_parallel_size`. This happens because:
When using sequence parallelism, your effective global batch size is **divided** by the `sequence_parallel_degree`. This happens because:
- Each group of `context_parallel_size` GPUs works on the same batch (just different parts of each sequence)
- Each group of `sequence_parallel_degree` GPUs works on the same batch (just different parts of each sequence)
- The number of batches processed per step decreases
For example:
- With 8 GPUs and no sequence parallelism: 8 different batches processed per step
- With 8 GPUs and `context_parallel_size=4`: Only 2 different batches processed per step (each split across 4 GPUs)
- With 8 GPUs and `sequence_parallel_degree=4`: Only 2 different batches processed per step (each split across 4 GPUs)
- If your per-GPU `micro_batch_size` is 2, the global batch size decreases from 16 to 4

# Arctic Long Sequence Training (ALST)
Artic Long Sequence Training (ALST) is a technique for training long context models using a variety of optimization
techniques. It is a combination of:
- TiledMLP: Leverage tiling over the sequence dimension on MLP layers to reduce memory usage
- Tiled Loss: Using optimized loss functions like Liger-Kernel or Cut Cross Entropy to reduce memory usage
- Activation Offloading: Offload activations to CPU RAM to reduce memory usage
For more information, you can check out the ALST paper [here](https://www.arxiv.org/abs/2506.13996).

# Finetune ArceeAI's AFM with Axolotl
[Arcee Foundation Models (AFM)](https://huggingface.co/collections/arcee-ai/afm-45b-68823397c351603014963473) are a family of 4.5B parameter open weight models trained by Arcee.ai.
This guide shows how to fine-tune it with Axolotl with multi-turn conversations and proper masking.
Thanks to the team at Arcee.ai for using Axolotl in supervised fine-tuning the AFM model.
## Getting started
1. Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html). You need to install from main as AFM is only on nightly or use our latest [Docker images](https://docs.axolotl.ai/docs/docker.html).
Here is an example of how to install from main for pip:
```bash
# Ensure you have Pytorch installed (Pytorch 2.6.0 min)
git clone https://github.com/axolotl-ai-cloud/axolotl.git
cd axolotl
pip3 install packaging==23.2 setuptools==75.8.0 wheel ninja
pip3 install --no-build-isolation -e '.[flash-attn]'
```
2. Run the finetuning example:
```bash
axolotl train examples/arcee/afm-4.5b-qlora.yaml
```
This config uses about 7.8GiB VRAM.
Let us know how it goes. Happy finetuning! 🚀
### TIPS
- For inference, the official Arcee.ai team recommends `top_p: 0.95`, `temperature: 0.5`, `top_k: 50`, and `repeat_penalty: 1.1`.
- You can run a full finetuning by removing the `adapter: qlora` and `load_in_4bit: true` from the config.
- Read more on how to load your own dataset at [docs](https://docs.axolotl.ai/docs/dataset_loading.html).
- The dataset format follows the OpenAI Messages format as seen [here](https://docs.axolotl.ai/docs/dataset-formats/conversation.html#chat_template).

# ND Parallelism Examples
This directory contains example configurations for training models using ND Parallelism in Axolotl. These examples demonstrate how to compose different parallelism strategies (FSDP, TP, CP, HSDP) for efficient multi-GPU training.
## Quick Start
1. Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html).
2. Run the command below:
```bash
# Train Qwen3 8B with FSDP + TP + CP on a single 8-GPU node
axolotl train examples/distributed-parallel/qwen3-8b-fsdp-tp-cp.yaml
# Train Llama 3.1 8B with HSDP + TP on 2 nodes (16 GPUs total)
axolotl train examples/distributed-parallel/llama-3_1-8b-hsdp-tp.yaml
```
## Example Configurations
### Single Node (8 GPUs)
**Qwen3 8B with FSDP + TP + CP** ([qwen3-8b-fsdp-tp-cp.yaml](./qwen3-8b-fsdp-tp-cp.yaml))
- Uses all 3 parallelism dimensions on a single node
- Ideal for: when model weights, activations, and/or context are too large to fit on single GPU
```yaml
dp_shard_size: 2 # FSDP across 2 GPUs
tensor_parallel_size: 2 # TP across 2 GPUs
context_parallel_size: 2 # CP across 2 GPUs
# Total: 2 × 2 × 2 = 8 GPUs
```
### Multi-Node
**Llama 3.1 8B with HSDP + TP** ([llama-3_1-8b-hsdp-tp.yaml](./llama-3_1-8b-hsdp-tp.yaml))
- FSDP & TP within nodes, DDP across nodes to minimize inter-node communication
- Ideal for: Scaling to multiple nodes while maintaining training efficiency
```yaml
dp_shard_size: 4 # FSDP within each 4-GPU group
tensor_parallel_size: 2 # TP within each node
dp_replicate_size: 2 # DDP across 2 groups
# Total: (4 × 2) × 2 = 16 GPUs (2 nodes)
```
