Title

Exploring the Intersection of HPC and AI: Challenges and Opportunities in Performance Portability and Decentralized Learning

Abstract

The convergence of high-performance computing (HPC) and artificial intelligence (AI) has proven strong results on a wide range of applications that demand higher computational power due to the vast amounts of data and analytics enabled by heterogeneous HPC platforms. However, given the complexity of developing efficient portable HPC and AI applications, performance engineering presents serious challenges. This talk discusses the challenges that have emerged with developing portable HPC and data-driven applications and how we are likely to react to those challenges. In particular, it presents our contribution to automating the process of selecting an appropriate configuration based on the properties of the code to achieve speedups and power efficiency. Additionally, it presents our approach on performance portability for deploying efficient AI kernels across multiple platforms with only a minimum of programming effort. Finally, the talk gives an overview of our ongoing research on AI-assisted parallelism discovery and high-performance decentralized learning.
