PROGRAM
The objective of such workshop is multifold:
- Engage with the Community of Expert Users: Conduct an in-depth consultation process with domain experts to identify the essential core functionalities required by application codes, ensuring that the ExaNLA library meets the most pressing needs of its primary users.
- Initiate Brainstorming Sessions: Begin a series of collaborative discussions to address the needs and challenges in developing the new ExaNLA library.
- Programming Languages: Evaluate the suitability of different programming languages for developing a high-performance and scalable ExaNLA library.
- Parallel Programming Models: Explore various parallel programming models that can optimize the library’s performance on modern architectures.
- Interfaces: Consider user-friendly and versatile interfaces that facilitate easy integration with existing applications and workflows.
- Templating: Discuss the use of templating to enhance code reuse, flexibility, and maintainability, allowing for easier adaptation to different computational environments and various range of accuracy.
- Fault Tolerance: Design and develop an efficient fault tolerance middleware for the ExaNLA library, and explore options for integrating a checkpointing mechanism into it.
- Designing for Performance and Adaptability: Explore the feasibility of incorporating automatic mechanisms within the library to enhance performance and adaptability.
- Automatic Symmetry Discovery and Algorithm Selection: Implement features that can automatically detect symmetries in matrices and select the most appropriate algorithms, optimizing computational efficiency.
- AI-Driven Optimization: Utilize AI techniques to optimize and select platform-specific kernels dynamically, ensuring that the library can leverage the best available hardware resources.
- Establish a Robust RSE Framework: Set up a research software engineering (RSE) framework based on Agile methodologies to ensure a streamlined and efficient development process. This framework incorporates:
- Continuous Integration (CI): Regularly integrate code changes to maintain software stability and identify issues early.
- Continuous Development (CD): Enable ongoing software enhancements and feature additions.
- Continuous Benchmarking (CB): Implement a process for regular performance testing to ensure the library meets its speed and scalability targets.
- Test Driven Development (TDD): Adopt a TDD approach to ensure code reliability and robustness, with tests guiding development from the outset.
- Application-driven benchmarking: Perpetual execution of application-driven benchmarks, including comparison against evolving existing libraries.
