(Keynote Presentation) Performance Optimization and Portability: Strategies for the Era of Heterogeneous HPC Systems
DescriptionIn today’s HPC landscape and especially in tomorrow’s even more complex systems, performance optimization and portability are critical for maximizing computational efficiency, minimizing energy consumption, and ensuring that applications can seamlessly adapt to rapidly evolving heterogeneous architectures.This talk will discuss challenges and solutions for performance optimization and portability of applications in modern HPC systems featuring increasingly heterogeneous architectures. Drawing from recent experiences in optimizing legacy applications, new simulation frameworks, and complex data analysis pipelines, we will examine approaches to effectively leveraging multiple levels of parallelism—both within nodes and across nodes—while maintaining performance portability. Topics will include scheduling libraries and autotuning, scalable domain decomposition, and runtime scheduling of workflows integrating AI, data management, and simulations. The discussion will conclude with recommendations for exploiting the multilevel parallelism and heterogeneity of next-generation accelerated HPC systems.
