Unified Inference Frontend (UIF) consolidates the following compute platforms under one AMD inference solution with unified tools and runtime:
- AMD EPYC™ and AMD Ryzen™ processors
- AMD Instinct™ and AMD Radeon™ GPUs
- AMD Versal™ Adaptive SoCs
- Field Programmable Gate Arrays (FPGAs)
UIF accelerates deep learning inference applications on all AMD compute platforms for popular machine learning frameworks, including TensorFlow, PyTorch, and ONNXRT. It consists of tools, libraries, models, and example designs optimized for AMD platforms. These enable deep learning application and framework developers to enhance inference performance across various workloads, including computer vision, natural language processing, and recommender systems.
UIF 1.2 adds support for AMD Radeon™ GPUs in addition to AMD Instinct™ GPUs. Currently, MIGraphX is the acceleration library for both Radeon and Instinct GPUs for Deep Learning Inference. UIF supports 50 optimized models for Instinct and Radeon GPUs and 84 for EPYC CPUs. The AMD Vitis™ AI Optimizer tool is released as part of the Vitis AI 3.5 stack. UIF Quantizer is released in the PyTorch and TensorFlow Docker® images. Leveraging the UIF Optimizer and Quantizer enables performance benefits for customers when running with the MIGraphX and ZenDNN backends for Instinct and Radeon GPUs and EPYC CPUs, respectively. This release also adds MIGraphX backend for AMD Inference Server. This document provides information about downloading, building, and running the UIF v1.2 release.
The highlights of this release are as follows:
AMD Radeon™ GPU:
- Support for AMD Radeon™ PRO V620 and W6800 GPUs. For more information about the product, see https://www.amd.com/en/products/professional-graphics/amd-radeon-pro-w6800.
- Tools for optimizing inference models and deploying inference using the AMD ROCm™ platform.
- Inclusion of the rocAL library.
Model Zoo:
- Expanded set of models for AMD CPUs and new models for AMD GPUs.
ZenDNN:
- TensorFlow, PyTorch, and ONNXRT with ZenDNN packages for download (from the ZenDNN web site)
ROCm:
- Docker containers containing tools for optimizing models for inference
- 50 models enabled to run on AMD ROCm platform using MIGraphX inference engine
- Up to 5.3x the throughput (images/second) running PT-OFA-ResNet50 with 78% pruned FP16 model on an AMD MI100 accelerator powered production server compared to the baseline FP32 PT- ResNet50v1.5 model. (ZD-041)
- Docker containers for running AMD Inference Server
AMD Inference Server provides a common interface for all inference modes:
- Common C++ and server APIs for model deployment
- Backend interface for using TensorFlow/PyTorch in inference for ZenDNN
- Additional UIF 1.2 optimized models examples for Inference Server
- Integration with KServe
Introducing Once-For-All (OFA), a neural architecture search method that efficiently customizes sub-networks for diverse hardware platforms, avoiding high computation costs. OFA can achieve up to 1.69x speedup on MI100 GPUs compared to ResNet50 baselines.
