Emerging Trends in Software Tools for Exascale Application Development

The recent achievement of exascale computing performance represents a monumental leap in high-performance computing, yet it introduces a complex landscape for software developers. The increased diversity and intricacy of these supercomputing systems necessitate a new era of algorithms and programming techniques tailored for optimal performance across varied architectures. Key to leveraging these capabilities is the development and deployment of sophisticated software tools that can effectively diagnose performance bottlenecks and debug code in the exascale context. In spite of that, as architectures evolve rapidly, existing tools may fall short in addressing the unique challenges posed by these powerful machines.

This Research Topic aims to explore the evolving role of software tools in the era of post-exascale computing. We are particularly interested in submissions that provide a forward-looking perspective on the tools and strategies needed to support application development on these advanced systems. As developers grapple with increased complexity and strive for portability among disparate architectures, the development of innovative, scalable software tools becomes ever more critical. These tools should not only address current performance analysis and debugging needs but also anticipate future developments in computing architecture.

We invite contributions that examine a wide range of topics within this theme, including but not limited to:
• The development of performance measurement and visualization tools designed for exascale systems.
• Advances in debugging and correctness-checking applications at scale.
• New approaches for modeling and predicting performance across diverse computational architectures.
• Innovative strategies for managing resource utilization effectively—from single-node memory usage to multi-node orchestration.
• Case studies demonstrating effective tool usage in real-world exascale computing scenarios.
Through this call for papers, we aim to gather insights into the successes, challenges, and emerging directions in the field of software tools for exascale computing. Submissions should aim to provide actionable insights into how tools can evolve to meet the demands of the next generation of high-performance computing platforms, thereby enabling developers to fully exploit the potential of exascale technology.
