Enhancing HPC Usability: Overcoming Challenges in High-Performance Computing for Science

Join us for the FAST-OS Workshop on July 9-10, 2002, led by Fred Johnson, as we explore the ongoing challenges in high-performance computing (HPC) for scientific applications. Despite advancements over the past fifteen years, many systems remain inefficient and fragile. Our vision is to develop a comprehensive integrated software environment that dramatically improves application performance, ease of use, and time to solution. We'll discuss system administration, software development, and the importance of various HPC components such as schedulers, compilers, visualizations, and fault tolerance.
