Advances in Artificial Intelligence (AI) and Machine Learning (ML) are beginning to revolutionize medicine, manufacturing, commerce, transportation, and other key aspects of our lives. However, such transformative effects are predicated on providing high-performance compute capabilities to enable these learning algorithms. Domain specific accelerators are an efficient and performant means to meet the compute requirements of these large-scale AI/ML. As the new age data-centers become heterogeneous with these emerging domain specific hardware, we must rethink both the architecture and the corresponding system stack.
In this talk, I will provide an overview of my contributions to design, deploy, and utilize accelerators for a wide class of AI/ML applications. I will first discuss pioneering works TABLA and DaNA, which are comprehensive full-stack solutions for machine learning accelerators that integrate with data management systems. These solutions expose a high-level programming interface to programmers that have limited knowledge about hardware design, nevertheless, can benefit from performance and efficiency gains through acceleration. Then, I will describe FAE, a novel framework that leverages statistical properties of data to best utilize the heterogeneous compute and memory resources for recommender model training. Finally, I will conclude with my future research vision towards devising architectures and systems for sustainable massive-scale distributed AI/ML by exploring the challenges which arise from the cross-pollination of different components in the data processing pipeline.
