Title: Enabling Efficient Trillion Parameter Scale Training for Deep Learning Models

Abstract: Deep Learning (DL) is driving unprecedented progress in a wide range of Artificial Intelligence domains, including natural language processing, vision, speech, and multimodal. Sustaining this rapid pace of AI revolution, however, requires practical solutions to the extreme demands of model scaling on the compute, memory, communication, and storage components of modern computing hardware. To address this challenge, we created a deep learning optimization library called DeepSpeed to make distributed model training and inference efficient, effective, and easy on commodity hardware. This talk will focus on DeepSpeed optimizations for improving memory and compute of extreme-scale model training.

Speaker Bio:Olatunji (Tunji) Ruwase is the lead and co-founder of the DeepSpeed project at Microsoft. His broad industry and research background spans compilers, operating systems, and hardware accelerators. His current focus is on systems and convergence optimizations, and frameworks for efficient distributed training and inference of deep learning models. His research results on DL training, inference, and hyperparameter search are used in multiple Microsoft systems and products, such as Azure, Ads, Bing, Catapult, and HyperDrive. Tunji earned a PhD in Computer Science from Carnegie Mellon University under the guidance of Professor Todd Mowry.

Title: Toward a Holistic Performance Evaluation of Large Language Models Across Diverse AI Accelerators

Abstract: Artificial intelligence (AI) methods have become critical in scientific applications to help accelerate scientific discovery. Large language models (LLMs) are being considered a promising approach to address some challenging problems because of their superior generalization capabilities across domains. The effectiveness of the models and the accuracy of the applications are contingent upon their efficient execution on the underlying hardware infrastructure. Specialized AI accelerator hardware systems have recently become available for accelerating AI applications. However, the comparative performance of these AI accelerators on large language models has not been previously studied. In this work, we systematically study LLMs on multiple AI accelerators along with GPUs and evaluate their performance characteristics for these models. We evaluate these systems with (i) a micro-benchmark using a core transformer block, (ii) a GPT-model, and (iii) an LLM-driven science use case, GenSLM.

Next, I will focus on recent work on evaluating inference capabilities of these systems, besides an orthogonal approach of various implementation frameworks. I will present our findings and analyses of the models’ performance to better understand the intrinsic capabilities of AI accelerators in this benchmarking effort

Title: A 4D Hybrid Algorithm to Scale Parallel Training to Thousands of GPUs

Abstract: Training large language models (LLMs) has become a highly compute-intensive domain of AI research, requiring clusters with tens of thousands of GPUs. Heavy communication, in particular, collective operations, can become a critical performance bottleneck in scaling the training of multi billion-parameter neural networks to large-scale parallel systems. In this talk, I will present a novel 3D tensor + data parallel hybrid algorithm implemented in a highly scalable, open-source framework called AxoNN. I will describe several performance optimizations in AxoNN to overlap non-blocking collectives with computation, and use of performance models to decide performance optimal configurations within the large search space defined by our 4D algorithm. These have resulted in unprecedented scaling and peak flop/s on NVIDIA A100 and AMD MI250X GPU-based supercomputers.
