Exa-MA: Methods and Algorithms for Exascale

Building the future of exascale computing through advanced numerical methods, AI-enhanced algorithms, and production-ready open-source software.

1. Our Mission

The Exa-MA project is part of France’s PEPR NumPEx initiative, dedicated to pushing the frontiers of exascale computing. We develop and deploy:

Advanced Methods

Novel discretizations, solvers, and algorithms optimized for exascale architectures

AI Integration

Scientific machine learning for simulation, model reduction, and optimization

Open Software

Production-ready libraries that abstract hardware complexity and enable seamless portability

Validated Impact

Demonstrators, benchmarks, and real-world applications across scientific domains

Exa-MA brings together leading French institutions (CEA, École Polytechnique, Inria, Sorbonne Université, Université de Strasbourg) with a budget of 6.255 M€ over the project duration.
