ONNX Runtime and AMD logo side by side

ONNX Runtime is an open-source project that is designed to accelerate machine learning across a wide range of frameworks, operating systems, and hardware platforms. Today, we are excited to announce a preview version of ONNX Runtime in release 1.8.1 featuring support for AMD Instinct™ GPUs facilitated by the AMD ROCm™ open software platform. Users can now use AMD Instinct™ GPUs with ONNX Runtime to accelerate distributed training for large-scale DNN models. AMD ROCm™ becomes the latest ONNX Runtime execution provider, continuing the Microsoft mission to endorse choice and versatility in targeting different compute devices and server platforms.

The ROCm Open Software Platform

ROCm is AMD’s open software platform for GPU-accelerated high-performance computing and machine learning workloads.  Since the first ROCm release in 2016, the ROCm platform has evolved to support additional math, AI and machine learning, and communication libraries and tools, a wider set of Linux® distributions, and a range of new GPUs. This includes the AMD Instinct™ MI100 GPU, the first AMD data center accelerator based on the compute-optimized AMD CDNA™ architecture.

The primary focus of ROCm has been high-performance computing at scale. The combined capabilities of ROCm and the AMD Instinct family of data center accelerators are well suited to accelerate AI/ML training using ONNX Runtime.

Accelerated training with ONNX Runtime on AMD GPUs

Large transformer models like GPT2 have proven themselves state of the art in natural language processing (NLP) tasks like NLP understanding, generation, and translation. They are also proving useful in applications like time-series prediction and computer vision. Due to their size, these models need to be trained in a large‑scale, distributed GPU environment. ONNX Runtime, with support from AMD (rocBLAS, MIOpen, hipRAND, and RCCL) libraries, enables users to train large transformer models in mixed‑precision in a distributed AMD GPU environment. Thus, ONNX Runtime on ROCm supports training state-of-art models like BERT, GPT-2, T5, BART, and more using AMD Instinct™ GPUs. Data scientists, researchers, students, and others in the community have an option to accelerate workloads using ONNX Runtime on AMD GPUs. This includes AMD Instinct™ MI100, AMD Radeon Instinct™ MI50, and AMD Radeon™ Pro VII GPUs.

Today, we are happy to announce the preview of Python™ packages supporting ONNX Runtime on ROCm, making it easy to get started with ROCm and ONNX Runtime.

Training performance acceleration

In this preview, we have demonstrated clear performance gains with ONNX runtime using AMD GPUs for fine-tuning GPT2 using HuggingFace on eight AMD Instinct™ MI100 GPUs. We see an 18 percent performance gain in these experiments relative to standalone PyTorch along and validated well-matched loss curves.

In general, the preview ONNX Runtime-ROCm library can be used in multi-node MI100 AMD GPU configurations with high-speed interconnects for inter-GPU communications. As we proceed to our official release, we expect users to see excellent performance across a wide range of Transformer models and ML/AI workloads, offering users a highly performant choice for their datacenter applications.

Getting started with ONNX runtime on AMD GPUs

With Python packages

In a ROCm enabled environment, users can get off to a quick start with a pip install:

pip install onnxruntime-training -f

Plugging their Pytorch script to ONNX runtime only* requires wrapping the model with

model = ORTModule(model)

More details are available at pytorch/ort: Accelerate PyTorch models with ONNX Runtime.

*PyTorch model should use standard PyTorch to support export to ONNX.

With Dockerfiles

Users can also take advantage of a simple Dockerfile to get pre-configured packages of the ROCm libraries, Pytorch, and ONNX Runtime.

The stable ONNX runtime 1.8.1 release is now available at ort/Dockerfile.ort-torch181-onnxruntime-stable-rocm4.2-ubuntu18.04 at main · pytorch/ort

More details are available at pytorch/ort.
