Title: Transitioning High-Performance Computing Systems through Dynamic Scheduling and Resource Allocation

Abstract: This keynote talk will delve into the current challenges in High-Performance Computing (HPC) systems, such as the waiting times and low resource utilization derived from batch queue systems, and the underutilization of GPUs due to their fixed allocation. The speaker will then introduce two solutions that address these issues: time-slice execution and the AI computing broker. Time-slice execution efficiently runs applications by eliminating unnecessary waiting times and idle nodes, thereby significantly improving system utilization and user experience. The AI computing broker, on the other hand, enhances GPU utilization by dynamically allocating GPUs only during necessary stages of an application's execution. This talk aims to introduce these new technologies to optimize the efficiency and enhance the usability of high-performance computing systems.
