Exa-DI: the first mini-application resulting from co-development is now available!
Following the Exa-DI general meetings, working groups were formed to produce applications on four major themes. The first mini application on high-precision discretisation is now available.
Following the Exa-DI workshops, four working groups (WGs) were formed, bringing together all the players involved in co-design and co-development: Exa-DI’s Computational and Data Science (CDT) team, members of the various targeted NumPEx projects, and application demonstration teams. These groups focus on efficient discretisation, unstructured meshes, block-structured AMR, and AI applied to linear inverse problems at exascale, and are now actively moving forward.
Thanks to these WGs, the first shared mini-applications, representative of the technical challenges of exascale applications, are currently being developed. They integrate high value-added software components (libraries, frameworks, tools) provided by other NumPEx teams. In this context, the first mini-application on high-precision discretisation is now available, with others to follow soon.
A documentation hub, set up in early 2025, is gradually centralising tutorials and technical documents of general interest for NumPEx Exa-DI. It includes: the NumPEx software catalogue, webinars and training courses, documentation on co-design and CDT packaging, and much more.
Feel free to consult it to stay up to date on the tools and resources available.

Exa-DI: Facilitating the deployment of HPC applications with Package Managers
Exa-DI is proud to present its series of training courses for users of package managers, designed to optimise their user experience.
Deploying and porting applications on supercomputers remains a complex and time-consuming task. NumPEx encourages users to leverage package managers, allowing for precise and direct control of their software stack, with a particular focus on Guix and Spack.
A series of training courses and support events has been organised to assist users:
• Tutorial: Introduction to Guix – October 2025
• Tutorial @ Compass25: Guix-deploy – June 2025
• Coding session: Publishing packages on Guix-Science – May 2025
• Tutorial: Spack for beginners (online) – April 2025
• Tutorial: Using Guix and Spack for deploying applications on supercomputers – February 2025
Switching to new deployment methods takes time. NumPEx supports users by offering training, support, software packaging, tool improvements, and partnerships with computing centres to optimise the user experience.
