Workshop on Numerical Algorithms and Computer Arithmetic for Computational Science 2026 (NACA 2026)
in conjunction with
The International Conference on Computational Science 2026 (ICCS 2026)
Description
The Workshop on Numerical Algorithms and Computer Arithmetic for Computational Science 2026 (NACA 2026) welcomes submissions that showcase advancements in numerical algorithms and computer arithmetic across various fields of computational science. This includes modelling and simulation, as well as high-performance computing and data-intensive algorithms for scientific applications. While submissions can explore a wide array of topics, the following areas are particularly of interests:
Foundations of computer arithmetic: emerging number systems and their applications
Novel arithmetic algorithms, their analysis, and applications
Efficient, high-performance, novel implementations of computer arithmetic in software and hardware
Integer or floating-point operations, elementary and special functions, multiple-precision computing, interval arithmetic
New algorithms and properties of floating-point arithmetic in emerging domains and applications
Computer arithmetic has always been at the core of the digital age and is currently driving innovation in domains such as artificial intelligence, high-performance computing, signal processing and security. Scientists across diverse fields heavily rely on numerical algorithms that require computer arithmetic awareness to avoid oversolving. There is a specific demand for scalable tools that are highly efficient and achieve high user-productivity while solving large-scale problems on massively parallel systems. This Thematic Track focuses on numerical algorithms and computer arithmetic, giving special attention to the latest scientific trends and challenges related to implementing numerical software libraries. The objective is to bring together researchers from different institutes, enabling the exchange of experiences and fostering research collaborations.
