High Performance Machine Learning, Deep Learning, and Data Science
Speakers: Dhabaleswar K. (DK) Panda, Hari Subramoni, Arpan Jain, and Aamir Shafi (The Ohio State University)
Recent advances in Machine and Deep Learning (ML/DL) have led to many exciting challenges and opportunities. Modern ML/DL and Data Science frameworks including TensorFlow, PyTorch, and Dask have emerged that offer high- performance training and deployment for various types of ML models and Deep Neural Networks (DNNs). This tutorial provides an overview of recent trends in ML/DL and the role of cutting-edge hardware architectures and interconnects in moving the field forward. We will also present an overview of different DNN architectures and ML/DL frameworks with special focus on parallelization strategies for model training. We highlight new challenges and opportunities for communication runtimes to exploit high-performance CPU/GPU architectures to efficiently support large-scale distributed training. We also highlight some of our co-design efforts to utilize MPI for large-scale DNN training on cutting-edge CPU/GPU architectures available on modern HPC clusters. The tutorial covers training traditional ML models including— K-Means, linear regression, nearest neighbours—using the cuML framework accelerated using MVAPICH2-GDR. Also, the tutorial presents accelerating GPU-based Data Science applications using MPI4Dask, which is an MPI-based backend for Dask. Throughout the tutorial, we include hands-on exercises to enable attendees to gain first-hand experience of running distributed ML/DL training and Dask on a modern GPU cluster.
