As AI models continue to scale in size and complexity, deploying them efficiently requires strategic resource allocation. Tensor parallelism (TP) is a valuable technique for distributing workloads across multiple GPUs, reducing memory constraints, and enabling inference for large-scale models. However, the choice of TP configuration isn’t one-size-fits-all—it directly impacts performance, networking overhead, and cost efficiency.
This blog will introduce you to the updated AMD Docker image, specifically built and optimized for distributed training. As you will see, the optimized AMD ROCm Docker image makes training large AI models faster and more efficient. It includes updates such as better fine-tuning tools, improved performance for multi-GPU setups, and support for FP8 precision, which helps speed up training while using less memory, and can provide you with an overall smoother and more efficient training experience on popular models such as Flux and Llama 3.1 running on AMD GPUs.
AMD is excited to announce Instella, a family of fully open state-of-the-art 3-billion-parameter language models (LMs) trained from scratch on AMD Instinct™ MI300X GPUs. Instella models outperform existing fully open models of similar sizes and achieve competitive performance compared to state-of-the-art open-weight models such as Llama-3.2-3B, Gemma-2-2B, and Qwen-2.5-3B, including their instruction-tuned counterparts.
In this blog, we explore how DeepSeek-R1 achieves competitive performance on AMD Instinct™ MI300X GPUs, along with performance comparisons to H200 and a short demo application showcasing real-world usage. By leveraging MI300X, users can deploy DeepSeek-R1 and V3 models on a single node with impressive efficiency. In just two weeks, optimizations using SGLang have unlocked up to a 4X boost in inference speed, ensuring efficient scaling, lower latency, and optimized throughput. The MI300X’s high-bandwidth memory (HBM) and compute power enable execution of complex AI workloads, handling longer sequences and demanding reasoning tasks. With AMD and the SGLang community driving ongoing optimizations—including fused MoE kernels, MLA kernel fusion, and speculative decoding—MI300X is set to deliver an even more powerful AI inference experience.
PyTorch Fully Sharded Data Parallel (FSDP) is a data parallelism technique that enables the training of large-scale models in a memory-efficient manner. FSDP achieves this memory efficiency by sharding model parameters, optimizer states, and/or gradients across GPUs, reducing the memory footprint required by each GPU. This enables the training of large-scale models with lower total GPU memory than DDP (Distributed Data Parallel), in which the model weights and optimizer states are replicated across all processes. To learn more about DDP, refer to Distributed Data Parallel (DDP) training on AMD GPU with ROCm.
Optimizing LLM performance on GPUs is challenging due to diverse model needs, memory constraints, and balancing latency and throughput. This document examines how hardware utilization, memory and communication bandwidth and scaling, contribute to inference performance, detailing optimal configurations for AMD Instinct™ MI300X GPUs.
Composer, developed by MosaicML, is an open-source deep learning training library built on top of PyTorch, designed to simplify and optimize distributed training workflows. It supports scalable training on multiple nodes and efficiently handles datasets of various sizes. Composer integrates advanced techniques such as PyTorch Fully Sharded Data Parallelism (FSDP), elastic sharded checkpointing, training callbacks, and speed-up algorithms to enhance training performance and flexibility. It closely resembles PyTorch’s torchrun and has demonstrated exceptional efficiency when scaling to hundreds of GPUs.
In this blog post we will cover the bitsandbytes 8-bit representations. As you will see, the bitsandbytes 8-bit representations significantly help reduce the memory needed for fine-tuning and inferencing LLMs. There are many quantization techniques used in the field to decrease a model size, but bitsandbytes offers quantization to decrease the size of optimizer states as well. This post will help you understand the basic principles underlying the bitsandbytes 8-bit representations, explain the bitsandbytes 8-bit optimizer and LLM.int8 techniques, and show you how to implement these on AMD GPUs using ROCm.
Meta’s Llama models now support multimodal capabilities, expanding their functionality beyond traditional text-only applications. The Llama 3.2 models are available in a range of sizes, including medium-sized 11B and 90B multimodal models for vision-text reasoning tasks, and lightweight 1B and 3B text-only models designed for edge and mobile devices.
As the scale and complexity of generative AI and deep learning models grow, multinode training, basically dividing a training job across several processors, has become an essential strategy to speed up training and fine-tuning processes of large generative AI models like SDXL. By distributing the training workload across multiple GPUs on multiple nodes, multinode setups can significantly accelerate the training process.
In this blog post we will show you, step-by step, how to set-up and fine-tune a Stable Diffusion XL (SDXL) model in a multinode Oracle Cloud Infrastructure’s (OCI) Kubernetes Engine (OKE) on AMD GPUs using ROCm.
